Biophysical Characteristics and the Anthropogenic Activities in San Roque Riv...YogeshIJTSRD
River provides essential various ecosystem goods and services that are essential for living organisms’ survival. As such, its quality must be maintained to ensure the healthy condition of the environment as well as the safety of the community. The study aimed to assess the biophysical characteristics and the anthropogenic activities in San Roque River, Northern Samar. It employed descriptive research combined with laboratory analysis and SPSS was employed to treat and analyze the data.The study revealed that the physico chemical characteristics of the water in San Roque River in terms of temperature, pH, TSS, TDS, and turbidity were within the DENR standards. However, the water of the river was highly contaminated with total coli forms and fecal coli forms. Likewise, the salinity was beyond from the standard that made the water of the river salty. T test revealed that the characteristics of water during high and low tides showed no significant differences. On the contrary. It has shown significant difference on water parameters in terms of temperature, pH, TSS, TDS, BOD, and DO between high tide and the standards. Likewise, pH, TSS, BOD, and DO have shown significant difference on low tide with the standards. It also revealed that there were anthropogenic activities and practices of the community living along the river that directly affect the water quality and condition of the river. Moreover, this also concludes that there were no significant relationships on the characteristics of the water and the anthropogenic activities. Lastly, the San Roque River was classified as Class D river at the time of the conduct of the study. This concludes that the river needed rehabilitation so that the potential uses of the river would be maximized which would redound to better benefits of the community. Elvin L. Jarito | Gerald T.

Aquatic ecosystems are hot spots of most terrestrial biodiversity. They interact with their surrounding terrestrial area through food webs and habitat resources. The aquatic ecosystems also attract a wide range of other fauna including wading and migrating birds, amphibians, riparian mammals and insects. Furthermore, aquatic ecosystems have ability to recycle nutrients of wastewater. Despite many benefits they have, their potentiality in the rehabilitation of quarries is not well recognized. The recent effort on the rehabilitation of quarry site is mostly focused on terrestrial plants despite the fact that quarries life are heterogeneous ecosystems. Owing to this reason, there is a need of using the potential of aquatic ecosystems to enhance the rehabilitation of quarries sites. The present project is therefore focused on establishing the aquatic ecosystem at Wazo hill quarry.
The project won the 1st Prize in National Quarry Life Award in 2014 in Tanzania.

Spatial water quality variations of DMMMSU-NLUC watershed and citizens’ aware...Jomar Aban
The research study was able to capture the social perspectives of DMMMSU-NLUC stakeholders pertaining to sustainable watershed resources management. Gender seemed to have played a major factor when it comes to the awareness and initiatives of the respondents. Males seem to be more aware than females when it comes to theories but females, on the other hand, seem to be more aware of the practical concepts on watershed resources management. Further, females prefer to conduct hands-on community outreach activities regarding watershed conservation than males. In contrary, males prefer to be more initiative by attending more seminars regarding watershed management. Work and social status also played a key role in terms of the awareness and initiatives of respondents. Students, local government officials, and local citizens are only fairly aware on the effects of industrialization in our watershed resources. It is even surprising to know that local government officials are not aware on the effect of siltation to the quality and biodiversity of watershed resources.

Developing Australia's Tropical Water ResourceseWater
As Australia looks increasingly to its tropical northern lands as a prospective ‘food-bowl for Asia’ we should reflect on two important questions:
(i) Have we gained sufficient knowledge and wisdom from a century of unsustainable irrigation practices in southern Australia to do things differently in the future?
(ii) Is Northern Australia really the agricultural utopia that some in the community argue, and do the potential rewards justify the risks to our largely pristine and biodiverse tropical river basins?
Part one of this series describes the environmental consequences of water resources development in Australia’s south – in the Murray-Darling Basin.

Determination of pH, Dissolved Oxygen, Sulphate, Phosphate and Total Hardness...Hanieh Farzaneh
Sampling of the Physico-chemical factors from two stations on the surface water of Kukkarahalli Lake in Mysore City-India was carried out biweekly over a period of 3 months of 2014. The aims were to determine some Physico chemical parameters of water pollution. Temperature was measured using mercury in glass thermometer. Dissolved oxygen was determined by modified Winkler azide method while Phosphate was determined by Vendo Molybdate Method, Estimation of Sulphate as Sulphur in sample by Nephelometric Method, measurements of total hardness by Complexometric Method. The result revealed that the major causes of water quality deterioration were related to excess usage of fertilizers and chemicals for increasing yield of the crop or releasing the sewage into the lake, due to cumulative effect of human activities where in sewage disposal oxygen is used in decomposing these organic water, eutrophication which causes algal bloom and therefore inability of oxygen to adequately dissolved in the water or the lentic nature of the site where was no serious upturns. As this Lake also used to be a source of water supply to the city of Mysore, and today is a house of different variety of birds, animals, plants and fishes it is very essential to stop sewage disposal and illegal excessive land encroachments to eliminate the eutropohication of the lake, which this results of the Physico-chemical examination of this lake could be helpful in the management of the lake for its water quality and fisheries.
Ulhas River estuary has been polluted due to several anthropogenic activities in the nearby urban and industrial areas viz. Thane, Dombivli, Kalyan, Mumbra, Biwandi and Mira-Bhayander. the anthropogenic activities like sewage water and industrial effluent influx, agricultural fields, sand excavation, solid waste dumping has put tremendous pressure on the inhabitant fish species from the ambient water. Mudskippers were not the exception during the present study. The species like Boleophthalmus dussumieiri (Cuv. & Val.) fishery had dwindled to a threatened limit during the study. It was envisage to analyse the water quality through hydrological study and its impact on fishery of Boleophthalmus dussumieiri in the Ulhas River estuary.

Abstract: Environment is made up of natural factors like air, water and land. Each and every human activities
supports directly/indirectly by natural factors. India is facing a problem of natural resource scarcity, especially
of water in view of population growth and economic development. Due to growth of Population, advancement in
agriculture, urbanization and industrialization has made surface water pollution a great problem and decreased
the availability of drinking water. Many parts of the world face such a scarcity of water. Lakes are important
feature of the Earth’s landscape which are not only the source of precious water, but provide valuable habitats
to plants and animals, moderate hydrological cycles, influence microclimate, enhance the aesthetic beauty of
the landscape and extend many recreational opportunities to humankind .For issues, perspectives on pollution,
restoration and management of Bellandur Lake Falls under Bangalore Metropolitan city is very essential to
know their status but so far, there was no systematic environmental study carried out. Hence now the following
studies are essential namely Characteristics, Status, Effects (on surrounding Groundwater, Soil, Humans
health, Vegetables, Animals etc.,), resolving the issues of degradation, preparation of conceptual design for
restoration and management.

ABSTRACT- Fresh water resources are not unlimited. The high rate of increase of human population of Nepal and the
rapid rate of industrialization have created problems of disposal of waste water products. The domestic wastes, excretory
materials of both human and animals and industrial effluents are discharged into the nearly lakes, rivers, reservoirs and
tanks and even in the catchment area of the above water bodies. The undesirable substances are regularly mixed into the
water of pond through surface run-off that degrades the water quality. Since last several years, there have been added an
array of agricultural pesticides and insecticides, which are further seriously aggravating the problem of pollution both for
public health and aquaculture. The detailed information of water quality and status of affected living organisms of water
bodies are necessary for the implementation of any management plan. The present investigation encompasses on plankton
identifying the ecological quality of Chhapakaiya pond Birgunj, Nepal. Seasonal sampling from all the sampling sites (site
A, B, C, D) in winter, summer and rainy season for period of 12 months (November 2014 – October 2015) at 9:00-11: 00
AM. A total of 27 taxa from different classes of zooplankton were reported. The zooplanktons were reported to be
maximum (774.4 unit/L) during summer and minimum (539.2 unit/L) during the rainy season in Chhapakaiya pond.

Variation of Growth Dynamics and Resource Allocation Patterns of Dictamnus albusBRNSS Publication Hub
Dictamnus albus is a medicinally important plant distributed throughout South and central Europe, temperate Asia, and Himalayas. The present study was devised for the 1st time to understand the variation in growth characteristics and changes in allocation patterns in relation to altitude and habitats of Kashmir Himalaya. The present investigation revealed extensive variability in morphological parameters both within and across the individuals of different populations. Our findings clearly displayed significant divergence among sites which reveal a definite impact of altitude and habitat on morphological and reproductive features of the species under study. Our results are very useful to introduce the species into cultivation and developing strategies for conservation.
Macrobenthic Invertebrate assemblage along gradients of the river Basantar (J...Agriculture Journal IJOEAR
Abstract— A limnological investigation was carried out in River Basantar in the Jammu province of Jammu & Kashmir (India) during the period from December, 2009 to November, 2011 in order to analyse the effect of industrial pollution on the diversity and population density of Macrobenthic invertebrate fauna along the longitudinal profile of the river. A total of 27 macrobenthic invertebrate taxa inhabited the river; among these Arthropoda dominated the macrobenthic community (81.48%, 22 species) followed by Annelida (11.11%, 3 species) and Mollusca (7.41%, 2 species). The Discharge Zone (St II) had the highest mean standing crop of macrobenthic population while the lowest species number. Oligochaetes (Annelida) and Dipterans (Arthropoda) exhibited their abundance at polluted sites whereas Odonates, Ephemeropterans, Hemipterans, Coleopterans (Arthropoda) and Molluscs were abundant at least polluted sites. Tubifex tubifex, Branchiura sowerbyi, Limnodrillus hoffmeisteri, Chironomus, Tubifera, Psychoda and Physa acuta were identified as pollution indicator taxa while Progomphus, Cloeon, Baetis and Gyraulus as sensitive taxa.
Status of Phytoplankton Community of Kisumu Bay, Winam Gulf, Lake Victoria, K...theijes
Lake Victoria has undergone remarkable and diverse ecological perturbations which are as a result of physical, chemical and biological processes, together with human activities that take place in the watershed area and within the lake itself. The most observed effects include increases in phytoplankton biomass and frequent algal blooms. In this study species composition, abundance, spatial and temporal distribution of phytoplankton as well as total phytoplankton biomass of Kisumu Bay, (Winam Gulf), Lake Victoria, Kenya was studied for six months in the wake of climate change. Sampling was done every two weeks using a Van Dorn Water sampler to take water samples and algal cells were counted under an inverted microscope with the help of a Sedge-Wick Rafter Cell in order to determine density. Phytoplankton biomass indicated by chlorophyll-content was determined through cold extraction in acetone and subsequent quantification by spectrophotometry. Physicochemical parameters were measured in situ using respective meters, while plant nutrient levels were determined by spectrophotometric methods following standard methods of APHA 1985 and Gems (1992) Handbook. ANOVA test was used to determine any temporal and spatial variability in the biological factors. Regression and Pearson’s correlation analyses were done to establish relationships between these factors. LSD test was done to determine means which were significantly different. The results indicated that a total of 36 genera of algae belonging to Cyanophyta, Bacillariophyta, Chlorophyta and Pyrrophyta were present, with dominance of the classes in terms of number of species being in that order. Chroococcus species was the most abundant and its density was significantly different from all the others. Most algal species were more or less homogenously distributed in the bay (p=1.0000) and over the study period (p=1.0000), but their densities varied significantly between different species (p<0.0001). From these results, it can be concluded that the phytoplankton community within the bay is becoming very dynamic and could possibly portray the status in the whole lake. Diatoms are becoming increasingly dominant. There is continual increasing trend in physico-chemical factors. The information obtained from this work contributes to the understanding of ecological changes in the bay in response to climate change and variability and thus the threat to biodiversity. This information is therefore important for ecological and management purposes of the lake and understanding effects of climate change on ecosystem structure, functioning and productivity.
Macrobenthic community-structure--an-approach-to-assess-coastal-water-polluti...Md. Monjurul Hasan
A research on the assemblages of benthic macro faunal community in the coastal areas of Bangladesh was
conducted during February-March, 2015 following the standard methods to assess the status of environmental
pollution. The abundance (r=0.846) and species richness (r=0.864) of the macrobenthic communities were
signifcantly influenced by the water salinity of the sampling sites (p ≤ 0.05). Both the study areas namely the
Bakkhali River Estuary and the Meghna River Estuary showing the highest (3909 ± 540 ind./m2) and lowest (2236
± 689 ind./m2) density of benthic macrofaunal abundance respectively might be considered as moderately polluted
areas according to the results obtained from Shannon-Wiener index of species diversity (2.69 ± 0.13 and 2.00 ± 0.11
respectively) and Margalef’s species richness (2.21 ± 0.43 and 1.36 ± 0.11 respectively). Therefore, it is plausible
that the macrobenthic community explained in the present study might be a key future outline to assess the status of
coastal water pollution of those concerned areas of Bangladesh.

The continuous discharge of effluents into Warri River, impacts on its water quality parameters as well as plankton species which requires commensurate surveillance. This study focuses on its physicochemical characteristics and their influence on plankton composition and abundance. The surface water samples and plankton collected monthly from June to November 2014 were analyzed using standard methods. The physicochemical parameters showed variations among the stations. The ANOVA results revealed that water temperature, transparency, turbidity, TDS, conductivity, pH, acidity, Dissolved Oxygen and phosphate were significantly different (P <0.05) among the studied sites. A total of 849 plankton species identified; 814 species were phytoplankton consisting of four groups (Bacillariophyta> Chlorophyta> Euglenophyta> Cyanophyta, arranged in order of dominance. While zooplankton had 35 species grouped into 5 groups; Rotifera> Copepoda> Protozoa> Cladocera> Arachnida, in order of dominance. Pearson correlation revealed a significant correlation between different Plankton species population and some parameters (p<0.05). The principal component analysis labelled acidity, organic load, mineralization, nutrient, and organic pollution as influential factors governing plankton abundance in the studied area. These factors identify with materials from industries and human activities along the river, which results in the alteration of plankton composition, particularly Melosira granulata (Ehrenberg) Ralfs,1861. Inferred biological indicator of the water body. Diversity indices ranged from 0.28 to 1.39; Station 2 had the highest (1.39) and Station 1 the lowest species richness, a highly polluted river.

Effective Application Security in Software Delivery lifecycle using Deployment Firewall and DBOM
The modern software delivery process (or the CI/CD process) includes many tools, distributed teams, open-source code, and cloud platforms. Constant focus on speed to release software to market, along with the traditional slow and manual security checks has caused gaps in continuous security as an important piece in the software supply chain. Today organizations feel more susceptible to external and internal cyber threats due to the vast attack surface in their applications supply chain and the lack of end-to-end governance and risk management.
The software team must secure its software delivery process to avoid vulnerability and security breaches. This needs to be achieved with existing tool chains and without extensive rework of the delivery processes. This talk will present strategies and techniques for providing visibility into the true risk of the existing vulnerabilities, preventing the introduction of security issues in the software, resolving vulnerabilities in production environments quickly, and capturing the deployment bill of materials (DBOM).

Climate Impact of Software Testing at Nordic Testing DaysKari Kakkonen
My slides at Nordic Testing Days 6.6.2024
Climate impact / sustainability of software testing discussed on the talk. ICT and testing must carry their part of global responsibility to help with the climat warming. We can minimize the carbon footprint but we can also have a carbon handprint, a positive impact on the climate. Quality characteristics can be added with sustainability, and then measured continuously. Test environments can be used less, and in smaller scale and on demand. Test techniques can be used in optimizing or minimizing number of tests. Test automation can be used to speed up testing.
Observability Concepts EVERY Developer Should Know -- DeveloperWeek Europe.pdfPaige Cruz
Monitoring and observability aren’t traditionally found in software curriculums and many of us cobble this knowledge together from whatever vendor or ecosystem we were first introduced to and whatever is a part of your current company’s observability stack.
While the dev and ops silo continues to crumble….many organizations still relegate monitoring & observability as the purview of ops, infra and SRE teams. This is a mistake - achieving a highly observable system requires collaboration up and down the stack.
I, a former op, would like to extend an invitation to all application developers to join the observability party will share these foundational concepts to build on:

Epistemic Interaction - tuning interfaces to provide information for AI supportAlan Dix
Paper presented at SYNERGY workshop at AVI 2024, Genoa, Italy. 3rd June 2024
https://alandix.com/academic/papers/synergy2024-epistemic/
As machine learning integrates deeper into human-computer interactions, the concept of epistemic interaction emerges, aiming to refine these interactions to enhance system adaptability. This approach encourages minor, intentional adjustments in user behaviour to enrich the data available for system learning. This paper introduces epistemic interaction within the context of human-system communication, illustrating how deliberate interaction design can improve system understanding and adaptation. Through concrete examples, we demonstrate the potential of epistemic interaction to significantly advance human-computer interaction by leveraging intuitive human communication strategies to inform system design and functionality, offering a novel pathway for enriching user-system engagements.

Removing Uninteresting Bytes in Software FuzzingAftab Hussain
Imagine a world where software fuzzing, the process of mutating bytes in test seeds to uncover hidden and erroneous program behaviors, becomes faster and more effective. A lot depends on the initial seeds, which can significantly dictate the trajectory of a fuzzing campaign, particularly in terms of how long it takes to uncover interesting behaviour in your code. We introduce DIAR, a technique designed to speedup fuzzing campaigns by pinpointing and eliminating those uninteresting bytes in the seeds. Picture this: instead of wasting valuable resources on meaningless mutations in large, bloated seeds, DIAR removes the unnecessary bytes, streamlining the entire process.
In this work, we equipped AFL, a popular fuzzer, with DIAR and examined two critical Linux libraries -- Libxml's xmllint, a tool for parsing xml documents, and Binutil's readelf, an essential debugging and security analysis command-line tool used to display detailed information about ELF (Executable and Linkable Format). Our preliminary results show that AFL+DIAR does not only discover new paths more quickly but also achieves higher coverage overall. This work thus showcases how starting with lean and optimized seeds can lead to faster, more comprehensive fuzzing campaigns -- and DIAR helps you find such seeds.

I. INTRODUCTION
Kashmir, being predominantly an agricultural economy and having water and land as its most valuable natural resources, has lakes as the main sources of water, followed by rivers, streams and springs. These water bodies have a bearing on the economy of the state besides providing us the source of portable water, fish, vegetable foods and fodder. The freshwater bodies of Kashmir have not remained immune to anthropogenic pressures as a result of which many water bodies have got deteriorated during the last 50 years. As a result of degraded water quality, aquatic biodiversity has also got severely affected. In an aquatic ecosystem the life of aquatic biota is closely dependent on the physical, chemical and biological characteristics of water, each of which directly acts as a controlling factor. Therefore, for understanding the dynamics of an organism, a population or a community, knowledge of both the organism and its environment is required. It is in this backdrop of the rich biodiversity of the world famous Wular lake, a Wetland of International Importance (Ramsar site) confronting a number of ecological stresses, the present study on crustaceans, an important component of zooplankton community in terms of its diversity and abundance has been undertaken during 2013-2014 with a view to obtain the baseline data on such an important group of animals serving as an important link in theaquatic food chain and being very good and sensitive bio indicators to monitor the trophic status of the water body. The importance of zooplankton in other studies has also been highlighted by many workers. The occurrence and abundance of zooplankton depends on the productivity of the lake, which in turn is influenced by abiotic factors and the level of nutrients in the water body. Further, zooplankton occupies a key position in ecological pyramids and their role in trophic-dynamics is noteworthy (Pandit, 1980, 99). The physico-chemical parameters and nutrient status of water body play an important role in governing the production of plankton (especially zooplankton) which is the natural food of many species of fishes and also support the necessary amount of protein for the rapid growth of larval carps (Rahman and Hussain, 2008). Major zooplankton forms vary in their relative abundance and they belong to three groups: (i) Phylum Protozoa, (ii) Phylum Rotifera and (iii) Class Crustacea which is itself composed of orders like Cladocera, Copepoda, and Ostracoda.

Kashmir Valley situated in the northern part of Indiawithin the Himalayan region has a number of fresh waterbodies. These water bodies have a great diversity due totheir differences in origin and altitude. Increasingpopulation on the other hand has been responsible forintroducing many undesirable changes to these waterbodies. Among these, the Dal Lake, WularLake, AncharLake and Manasbal Lakeover the years, havebeen subjected to over exploitation for economicpurposes. Open water areas of the Dal Lake, WularLake, AncharLake and Manasballake have beenconverted into floating gardens to enhance agriculturalproduction while lake peripheries have been encroachedupon to construct residential houses and hotels. A largenumber of houseboats have encroached within the lakearea. Household wastes and sewage are drained into thelake indiscriminately at several sites. Agricultural run-offfrom the surrounding fields, especially the fertilizer andpesticide wastes from the floating gardens enter into thelake water. The excessive load of nutrients in the Lakewater has resulted into luxuriant growth of aquatic plants. This indiscrimination has led to the pollution and encroachment in certain areas mostly in littoral and limnetic zones from which the aquatic life have been totally vanished or vulnerable. This leads to environmental stress on limnetic water bodies and aquatic life. 1.1Literature Survey
However, due to multiple of problems the lakes isheading towards its destruction. With this background,the present study was carried out at the selected sites ofDal Lake, Wular lake, Anchar lake and Manasballake ,at two different periods of time to find out thechanges in the water quality over the years and itsimpact on Zooplanktons especially crustaceans like calanoids, , coyclopoids, cladocerans, copepoda, rotifera and other organisms. The present study will alsoreveal the impact of de-weeding and the magnitude ofthreat imposed by discharges from urban humansettlements to the ecology of the lake, so that possibleconservative measures could be undertaken to restorethe aquatic life.
1.2 Materials and Methods The present study would prove useful in understanding the conservative planning and management of polluting factors.

2. Physico-chemical analysis: Sampling was done once in amonth and samples were collected from both surfaceand bottom of the Lakes in polyethylene bottles of1 L capacity from pre-selected sites with the help ofRuttner type water sampler (Ruttner, 1968). Samplingwas done between 10 am to 12 noon. For thephysico- chemical analysis, standard methods assuggested by Welch (1948), Murphy and Riley (1962),Mackereth (1963), Golterman and Clymo (1969), TrivedyandGoel (1986) and APHA (1989) were followed.
3. Zooplankton sampling:Zooplankton sampling was carriedout on monthly basis from March 2013 to Apr 2014. However, the sampling fromMarch 2013 to Apr 2014 was done on seasonal basis(2 seasons) from the open water areas of the Lake almostdevoid of aquatic plants. The study of zooplankton wasdivided into two parts, viz., qualitative and quantitativeanalysis. For Qualitative analysis, standard planktonicnet (64 nm pore dia) was hauled through vertical andhorizontal planes of the lake at selected sites.The plankton collected in the 50 mL polyethylene bottleconnected at the lower end of the net was preserved in5% formalin. Then, 1 mL of this sample was taken at atime in a Sedgwick Rafter chamber and studied underthe phase contrast inverted microscope (Nikon) andsimple microscope. The identification was done with thehelp of keys given by Ward and Whipple (1959),Mellanby (1963), Pennak (1978) and Tonapi (1980).To collect sample for quantitative analysis of zooplanktonpopulation, 10 L of water was filtered through theplankton net and the water was allowed to filter throughthe net, the planktons were concentrated in the 50 mLpolyethylene bottle connected at the lower end of the net.The sample thus, obtained was preserved in 5% formalinand further reduced in volume to 5 mL by centrifugation.About 1 mL of concentrated preserved sample was takenat a time in a Sedgwick Rafter Chamber (Whipple et al.,1927) and counting was done for each zooplanktontaxon. The entire 5 mL of the concentrated sample wasstudied under phase contrast inverted microscope(Nikon) and other microscope. The results are expressedas individuals per litre.

Zooplankton in the Dal Lake, Wular lake, Ancharlake and Manasbal lake is represented by rotifersand crustacean (Jeelaniet al., 2005). A total of 40 taxa ofZooplankton of Dal lake were recorded during both the periods ofstudy. In the past studies carried out from July 2000 to Aug 2002, a total of 27 rotifer and 13 crustaceansand fromMarch 2013 to Apr 2014, 8 rotifer and 5 crustacean taxawere recorded respectively (Table 1,2 3 and 4; Fig. 4). Therotifer fauna shows single peak in population densityduring summer at all the sites in both the studies. Thesite-I is open water area of these Lakes which does notreceive domestic water directly. The site-II is shallow anddensely vegetated with macrophytes and at this site,species diversity and population was highest of all thesites. Both site-III and site-IV receive direct discharge ofdomestic sewages. The species composition has beenfound to be almost similar except BrachionusangularisPallus which is found at site-IV. However, over a periodof one decade, there has been a decline in the number oftaxa of rotifer in the Lakes evident from the studies carriedout from March 2013 to Apr 2014 in which only 8 rotifertaxa were recorded. Crustacean population in both theperiods of study increased during summer with a singlepeak. In all, 13 crustaceans belonging to cladoceraandcopepod were recorded during July 2000 to Aug 2002.Out of these, 12 were present at site-I and 13 each at allother sites of the Lake. However, during the studiedperiod from March 2013 to Apr 2014, the crustaceandiversity has shown a considerable decrease over aperiod of time.

Zooplankton diversity in Dal Lake, Wular lake, Anchar lake and Manasballake. The excessive load of nutrients in the Lakes has resultedinto excessive growth of aquatic vegetation. In the recentpast, a large scale mechanical de-weeding in the Lakeshas resulted into loss of crustacean as the aquaticvegetation provides food and shelter to them.

III. CONCLUSION
Several measures are being taken to restore the pristine glory of the Dal Lake, Wularlake, Anchar lake and Manasbal lake back. However, few measuresadversely affect the Lake ecology in general.The machines in place for the removal of nutrient richsediments and aquatic plants from the Lakes resulted intoloss of biodiversity as is evident from this study. The use of mechanical de-weeder has also resulted intothe loss of species diversity of Zooplankton in the Lakeover a period of time. The entry of untreated sewage,agricultural run-off from the floating gardens and solidwaste within and outside into the Lake water has resultedin nutrient enrichment of the water that has led toluxuriant growth of aquatic plants. In the recent pastreduction/erratic precipitation levels has led to decreaseof fresh water entry into the Lakes. At present, there is avery little control over point and non-point source ofpollution and the lack of public participation have alsoresulted into deterioration of the Dal Lake, Wularlake, Anchar lake and Manasbal lake waters.Concept of polythene recycling machine named (polyrecyler) designed by Ar.Taha Mughal under the supervision and guidance of Author Urfan Ali.This project was presented in 15th national children science congress 2007 at department of science and technology, vidhiyaprathisthanBaramatipune.(India)The machine was highly appreciated by jury from different professional universities and colleges.Schemematic representation of this machine is given below.For experiment yarinumbal site of Dal Lake was taken.
IV. DESIGN
This machine is made up of rotter blades and used on sites where polythene bags and other non- disposable items are thrown .By the help of rotter these materials is extracted from weeds(azolla)and the allow to shift into oil chambers where oil and other impurities was allow to absorb by any absorbent or hair could be used as substitute. Now from oil chamber polythene would be shifted to burning incinerator,which was a connected burning outlet. It is of two types one. Used for emitting gases and the gas were treated and made it suitable for extinguishers. While as other one outlet contains residue matter which would be set into steel mould and mixed with the material which could be used to make sanitary tiles ACKNOWLEDGEMENTS Authors are thankful to the scientists of LAWDA DEPARTMENT KAHMIR.
