Tendency Of Organic Aquaculture Development
The document discusses the development of organic aquaculture. It defines organic aquaculture as a production system that promotes biodiversity and biological cycles with minimal off-farm inputs. Common organic aquaculture species include salmon, carp, trout, shrimp, mussels and tilapia. Organic aquaculture has grown in Europe in recent decades and production is estimated to reach 500 million euros by 2011, though markets are still limited. Research focuses on alternative feeds and disease management to further the development of the industry.
Better practice guidelines for fish farmers
The document presents guidelines for sustainable and responsible marine pen and cage aquaculture in the Philippines. It discusses developing Better Practice Guidelines (BPGs) to provide farmers with practical advice based on lessons learned. The BPGs cover the full production cycle and aim to improve environmental management, animal welfare, social and economic sustainability over time. Key areas addressed include siting, design, hatchery practices, feeding, health, quality assurance, monitoring, social responsibility and waste management.
Ornamental fish culture
Ornamental fish culture provides opportunities for entrepreneurship and income generation. It requires a minimum of 500 sq ft of land and access to fresh water and electricity. Selection of quality broodstock is important, as different species prefer different water parameters for breeding. Beginners should start with livebearers like guppies and later move to egg-layers, focusing on one species at a time. CIFA has developed technologies for breeding 16 indigenous ornamental fish species and commercializing an endangered species. It conducts national training programs and facilitates entrepreneurs with business plans and information on government subsidies.
Jayachandran aquaculture systems
Aquaculture is the farming of aquatic organisms such as fish, mollusks, crustaceans, and plants. It involves interventions like regular stocking, feeding, and protection from predators to enhance production. Aquaculture provides food and nutritional security as capture fisheries production has stagnated. There are many types of aquaculture systems ranging from extensive pond culture to intensive recirculating aquaculture systems. Traditional Indian aquaculture includes integrated fish farming in paddy fields and modified extensive shrimp farming systems.
Organic aquaponics & organic aquaculture
This document presents information on organic aquaculture and aquaponics from a student presentation. It defines organic aquaculture according to IFOAM standards and discusses the differences between conventional and organic aquaculture systems. Specifically, it notes that organic aquaculture uses closed systems, avoids GMOs and antibiotics, relies on biological pest control, and aims to recycle nutrients and water. It then describes the components and functioning of a recirculating aquaculture system. Additional sections cover organic fish feeds, integrated organic aquaculture methods like aquaponics and fish-paddy culture, and case studies on the economic viability and costs of organic carp farming.
PROJECT REPORT PRESENTATION1
This project report presentation summarizes the design of a recirculating aquaculture system. It includes sections on introduction, objectives, literature review, methodology, results and recommendations. The student, Andrew Ayuka, designed a system with 12 culture tanks that can hold over 7,000 tilapia fish. Key aspects of the design include sizing the biofilter area at 375 square meters and volume at 1.735 cubic meters. Drawings show the layout and front view of the designed RAS. The conclusions discuss the advantages of RAS over fish ponds, and recommendations provide suggestions to support further research, development and training to advance aquaculture in Kenya.
ORGANIC AQUA - AQUACULTURE
Physiological stress and physical injury are the primary factors contributing to fish disease and mortality in aquaculture. Poor water quality, high fish density, parasites, pathogens, pollution and inadequate nutrition cause stress. Stress suppresses the immune system, disrupts osmoregulation, and reduces growth and reproduction, potentially causing death. Organicaqua's natural products help manage stress and disease by maintaining good water quality, dissolved oxygen levels, and appropriate temperatures and pH levels. The products stimulate aerobic waste decomposition, nitrification, and healthy dissolved oxygen levels to reduce stress, pathogens, and diseases and increase fish growth and stocking capacity. Before and after pictures from a case study show the products successfully treated toxic blue-green algae
Sewage fed fisheries
This document discusses sewage-fed fish culture, which involves using treated sewage water to culture fish. It provides background on the history and present status of sewage-fed fish culture. The key processes involved are primary and secondary sewage treatment through sedimentation, dilution, and storage before releasing into fish ponds. Farmers culture various fish species using techniques like pond preparation, primary fertilization through sewage, stocking, feeding, and harvesting fish for market. While sewage-fed culture benefits waste recycling and low input costs, it can also pose health risks if not properly managed.

This document summarizes a case study of introducing more environmentally friendly fishing gears for ornamental fisheries in Kepulauan Seribu, Indonesia. Previously, cyanide fishing had damaged coral reefs and provided low economic returns for fishermen. The study introduced alternative gears like barrier nets, mini harpoons, and fish traps from 2006-2007. Using these gears provided economic benefits by reducing costs, increasing fish quality and prices, and improving fishermen's livelihoods and health. The document recommends further developing and promoting sustainable fishing gears while restricting damaging practices and monitoring fish populations.
Fishery 8
This document discusses fishery, fish cultivation, kinds of fish, and the external and internal parts of fish and their functions. Fishery involves catching, handling, marketing, and preserving fish or aquatic products. Fish cultivation is the raising of aquatic products under controlled environments and is a good source of income, especially for export. There are two main kinds of fish - fin fish which have fins and scales, and shellfish which have outer shells like oysters, shrimps, crabs, crayfish, scallops, lobsters, and prawns. The document then lists the external and internal parts of fish and their functions.
Sewage fed fish culture
This document discusses sewage-fed fish culture as a new approach to pond fishing that has several advantages. Treated sewage water is rich in nutrients and can be used for aquaculture at low cost, requiring no fertilizer or supplemental feeding. The sewage undergoes sedimentation, dilution with fresh water, and storage with duckweeds to remove contaminants before use in fish ponds. Higher stocking densities and regular harvesting provide high production and profits. Sewage-fed fish culture improves water quality while generating additional income for farmers.
Recirculation in fish
The document discusses the application of recirculating aquaculture systems (RAS) in fish farming. RAS filter and recycle water from fish tanks through a treatment process before returning it to the tanks. This allows for high fish stocking densities while using little water. Key components of RAS include fish tanks, mechanical and biological filtration to remove waste, and oxygenation. RAS provide environmental and production benefits over other systems but also have higher capital and operating costs due to the water treatment infrastructure required.

This document discusses site selection factors for aquaculture. It outlines several key factors that must be considered, including ecological factors like water availability, quality and climate; biological factors; and social/economic factors. Specifically, it discusses water quality parameters like temperature, dissolved oxygen, pH, ammonia, nitrite and nitrate levels, and plankton quantities that greatly impact fish and shrimp survival. Maintaining optimal ranges for these various water quality parameters is essential for successful aquaculture production.
Aquaponic gardening
- Aquaponic gardening combines aquaculture (raising fish) and hydroponics (cultivating plants in water) to create a symbiotic system where the waste from the fish provides nutrients for the plants and the plants help filter the water for the fish.
- Several aquaponic systems were set up in Tanzania and South Korea to demonstrate how to integrate fish farming and vegetable/plant cultivation using locally available materials. Water quality parameters like pH and dissolved solids were monitored over time, showing the system helps purify the water.
- The aquaponic systems provided fresh fish and plants locally with less water, land, and nutrients needed compared to traditional soil-based gardening. They also required
Organic farming
Organic aquaculture refers to ecological production management systems that promote biodiversity and biological cycles. It is based on minimal off-farm inputs and holistic practices. Historically, organic aquaculture developed from the organic agriculture movement in the early 1990s in Europe. Standards were established and production has grown significantly since, now totaling over 50,000 tonnes globally per year. Major species include salmon, shrimp, and carp. Principles of organic aquaculture standards include an absence of GMOs, limited stocking densities, and nutrient recycling rather than intensive inputs. While still nascent, organic aquaculture is growing in India through projects like organic scampi farming in Andhra Pradesh.

This document describes the pond-based hatchery method for fingerling production. It involves stocking breeders into earthen ponds to spawn naturally. Fingerlings are collected after 21 days and ponds are drained after 45-50 days. The method has simple management but fingerlings vary in size. Preparation includes pond draining, pest elimination, fertilizing, and installing screens. Breeders are conditioned for 2 weeks before stocking. Fingerlings are collected weekly by seining until ponds are drained and reconditioned for the next cycle.

The students conducted experiments to analyze various properties of water, including:
1) Having students taste tap water and bottled water in a blind taste test, finding most students rated bottled water higher.
2) Surveying families to measure home water usage, finding an average of 195 liters per day and most were able to reduce usage with conservation tips.
3) Learning about the local water treatment and distribution system to ensure safe, clean drinking water through filtration, disinfection, and quality testing.
Aquaculture presentation by Komakech Richard
The document discusses the opportunities and challenges of aquaculture in Uganda. It begins by introducing aquaculture and explaining its importance as global fish catches decline and demand rises. Uganda has opportunities for aquaculture development including abundant water resources, suitable land, market availability, and fish species. However, challenges include the labor and capital intensity, lack of research and extension support, unreliable fish seed supply, absence of clear government policy, and environmental costs. While aquaculture can boost fish production, many factors must be addressed for the industry to thrive in Uganda.

FRESHWATER FARMING OF BRACKISHWATER SHRIMP, PENAEUS MONODON (FABRICIUS) WIT...American Research Thoughts
Abstract: Brackish water shrimp (Penaeus monodon) farming expanded rapidly after the technical
viability of this culture system was established and farmers discovered that the high profits derived
from shrimp production could easily offset increased costs associated with this culture. These factors
facilitate the spread of brackish water shrimp farming into freshwater agricultural areas of Purba
Medinipur district of West Bengal that never experience salt water intrusion. The emergence of
brackish water shrimp farming within paddy growing regions of Purba Medinipur district has raised
concerns regarding potential environmental impacts and the suitability of conducting this activity
within highly productive freshwater agricultural areas. In the present study an attempt had been
made to farm the black tiger shrimp, Penaeus monodon in almost freshwater condition with
innovative technologies in 04 earthen tanks each with 0.4 ha water spread area under Contai -III Dev.
Block in Purba Medinipur district in the year 2011 (April to August). The PCR tested P. monodon
seeds (PL15) were stocked in all freshwater earthen tanks after proper acclimatization @
50,000nos/tank. The salinity of the tanks was recorded between 0.0063 ppt to 0.04 ppt. The shrimps
were fed with branded feed and the feeding schedule was based on check-tray method as well as a feed
chart given by the concerned manufacturer.IRSP Water Quality Monitoring Protocol
Water is an essential element for our survival. Unfortunately, while Pakistan is blessed with adequate surface and groundwater resources, rapid population growth, urbanization and unsustainable water consumption practices have placed immense stress on the quality as well as the quantity of water resources in the country. Deterioration in water quality and contamination of lakes, rivers and groundwater aquifers has resulted in increased water-borne diseases and other health impacts.

The cost of acquiring information by natural selection
This is a short talk that I gave at the Banff International Research Station workshop on Modeling and Theory in Population Biology. The idea is to try to understand how the burden of natural selection relates to the amount of information that selection puts into the genome.
It's based on the first part of this research paper:

Candidate young stellar objects in the S-cluster: Kinematic analysis of a sub...
Context. The observation of several L-band emission sources in the S cluster has led to a rich discussion of their nature. However, a definitive answer to the classification of the dusty objects requires an explanation for the detection of compact Doppler-shifted Brγ emission. The ionized hydrogen in combination with the observation of mid-infrared L-band continuum emission suggests that most of these sources are embedded in a dusty envelope. These embedded sources are part of the S-cluster, and their relationship to the S-stars is still under debate. To date, the question of the origin of these two populations has been vague, although all explanations favor migration processes for the individual cluster members. Aims. This work revisits the S-cluster and its dusty members orbiting the supermassive black hole SgrA* on bound Keplerian orbits from a kinematic perspective. The aim is to explore the Keplerian parameters for patterns that might imply a nonrandom distribution of the sample. Additionally, various analytical aspects are considered to address the nature of the dusty sources. Methods. Based on the photometric analysis, we estimated the individual H−K and K−L colors for the source sample and compared the results to known cluster members. The classification revealed a noticeable contrast between the S-stars and the dusty sources. To fit the flux-density distribution, we utilized the radiative transfer code HYPERION and implemented a young stellar object Class I model. We obtained the position angle from the Keplerian fit results; additionally, we analyzed the distribution of the inclinations and the longitudes of the ascending node. Results. The colors of the dusty sources suggest a stellar nature consistent with the spectral energy distribution in the near and midinfrared domains. Furthermore, the evaporation timescales of dusty and gaseous clumps in the vicinity of SgrA* are much shorter ( 2yr) than the epochs covered by the observations (≈15yr). In addition to the strong evidence for the stellar classification of the D-sources, we also find a clear disk-like pattern following the arrangements of S-stars proposed in the literature. Furthermore, we find a global intrinsic inclination for all dusty sources of 60 ± 20◦, implying a common formation process. Conclusions. The pattern of the dusty sources manifested in the distribution of the position angles, inclinations, and longitudes of the ascending node strongly suggests two different scenarios: the main-sequence stars and the dusty stellar S-cluster sources share a common formation history or migrated with a similar formation channel in the vicinity of SgrA*. Alternatively, the gravitational influence of SgrA* in combination with a massive perturber, such as a putative intermediate mass black hole in the IRS 13 cluster, forces the dusty objects and S-stars to follow a particular orbital arrangement.

EWOCS-I: The catalog of X-ray sources in Westerlund 1 from the Extended Weste...
Context. With a mass exceeding several 104 M⊙ and a rich and dense population of massive stars, supermassive young star clusters
represent the most massive star-forming environment that is dominated by the feedback from massive stars and gravitational interactions
among stars.
Aims. In this paper we present the Extended Westerlund 1 and 2 Open Clusters Survey (EWOCS) project, which aims to investigate
the influence of the starburst environment on the formation of stars and planets, and on the evolution of both low and high mass stars.
The primary targets of this project are Westerlund 1 and 2, the closest supermassive star clusters to the Sun.
Methods. The project is based primarily on recent observations conducted with the Chandra and JWST observatories. Specifically,
the Chandra survey of Westerlund 1 consists of 36 new ACIS-I observations, nearly co-pointed, for a total exposure time of 1 Msec.
Additionally, we included 8 archival Chandra/ACIS-S observations. This paper presents the resulting catalog of X-ray sources within
and around Westerlund 1. Sources were detected by combining various existing methods, and photon extraction and source validation
were carried out using the ACIS-Extract software.
Results. The EWOCS X-ray catalog comprises 5963 validated sources out of the 9420 initially provided to ACIS-Extract, reaching a
photon flux threshold of approximately 2 × 10−8 photons cm−2
s
−1
. The X-ray sources exhibit a highly concentrated spatial distribution,
with 1075 sources located within the central 1 arcmin. We have successfully detected X-ray emissions from 126 out of the 166 known
massive stars of the cluster, and we have collected over 71 000 photons from the magnetar CXO J164710.20-455217.

Microbial interaction
Microorganisms interacts with each other and can be physically associated with another organisms in a variety of ways.
One organism can be located on the surface of another organism as an ectobiont or located within another organism as endobiont.
Microbial interaction may be positive such as mutualism, proto-cooperation, commensalism or may be negative such as parasitism, predation or competition
Types of microbial interaction
Positive interaction: mutualism, proto-cooperation, commensalism
Negative interaction: Ammensalism (antagonism), parasitism, predation, competition
I. Mutualism:
It is defined as the relationship in which each organism in interaction gets benefits from association. It is an obligatory relationship in which mutualist and host are metabolically dependent on each other.
Mutualistic relationship is very specific where one member of association cannot be replaced by another species.
Mutualism require close physical contact between interacting organisms.
Relationship of mutualism allows organisms to exist in habitat that could not occupied by either species alone.
Mutualistic relationship between organisms allows them to act as a single organism.
Examples of mutualism:
i. Lichens:
Lichens are excellent example of mutualism.
They are the association of specific fungi and certain genus of algae. In lichen, fungal partner is called mycobiont and algal partner is called
II. Syntrophism:
It is an association in which the growth of one organism either depends on or improved by the substrate provided by another organism.
In syntrophism both organism in association gets benefits.
Compound A
Utilized by population 1
Compound B
Utilized by population 2
Compound C
utilized by both Population 1+2
Products
In this theoretical example of syntrophism, population 1 is able to utilize and metabolize compound A, forming compound B but cannot metabolize beyond compound B without co-operation of population 2. Population 2is unable to utilize compound A but it can metabolize compound B forming compound C. Then both population 1 and 2 are able to carry out metabolic reaction which leads to formation of end product that neither population could produce alone.
Examples of syntrophism:
i. Methanogenic ecosystem in sludge digester
Methane produced by methanogenic bacteria depends upon interspecies hydrogen transfer by other fermentative bacteria.
Anaerobic fermentative bacteria generate CO2 and H2 utilizing carbohydrates which is then utilized by methanogenic bacteria (Methanobacter) to produce methane.
ii. Lactobacillus arobinosus and Enterococcus faecalis:
In the minimal media, Lactobacillus arobinosus and Enterococcus faecalis are able to grow together but not alone.
The synergistic relationship between E. faecalis and L. arobinosus occurs in which E. faecalis require folic acid
