Power point presentation in Fish diversity in Kankai river Jhapa district, Nepalumesh acharya
Fish are members of paraphyletic group of an organism that consist of all gills bearing aquatic carniates which lacks limbs with digits. Fish are considered as an important natural food resource, worldwide specially that of animal protein. Fishes are considered auspicious and symbolize as sign of fertility, power and prosperity in Nepal. There are about 185 fish species in Nepal belonging to 79 genera, 31 families and 11 orders (Shrestha. J.2001). 232 species of Fishes are found in Nepal (Shrestha T.K 2008). Among them 217 species are Indigenous and 15 species are exotic. The rivers of Nepal are really rich in fish fauna which need to be explored scientifically (shrestha. J.N.2001).
My study will deals with fish species present in kankai river of Jhapa district, which is largest and holiest river of jhapa district originated from george of mountains, flowing southward to low land of east terain. My research objective is to study the diversity of fish species in kankai River. To study the fish resources in kankai River, the condition of water will analyze with the help of water analysis kit. The fish will be collected with the help of local fishermen. The collected fish will be analyze in Tri-Chandra Multiple Campus Lab.

Aquaculture engineering is a multidisciplinary field of engineering and that aims to solve technical problems associated with farming of aquatic flora and fauna.
Nursery Pond Management
Objectives:
To obtain required amount of desirable species at desired time at desired price all the year round.
After completing these stages of management the nursery pond is prepared for rearing fry and fingerlings.
The next stage is to select culturable species for stocking in the prepared pond and other management.
If we prepare a good nursery pond we will get a good production .
Fishing Gear any form of equipment, implement, tool or mechanical device used to catch, collect or harvest fish. Fishermen in many parts of Bangladesh catch fish with their hands. In rural areas, in seasonal waters or beels, during winter, people can be usually seen fishing with different traditional gears while some even do so without any gear
Fishing is the art of catching fish and other aquatic animals. Many years ago man started using various type of gear used for hunting the terrestrial animals and for fishing also. It is very difficult to say which started first, but some time it is opined that fishing is younger. Reason behind it is easy to catch animals in the land than in the water. In olden days fishing was not having much importance as there was no demand for fish. Earlier fishing was restricted to a particular community but it is not so now. In order to meet the increased demand, fishing is now carried out industrially. Fishing technology not only concerns fishing gear, fishing methods and vessels but also concern Biological and Environmental factors

Trawl nets and bottom seines possess an initial selectiveness owing to their particular design and mode of operation. A mesh size limitation would vary considerably in effect from one type of trawl net to another. It is important therefore to consider gear selectivity and performance before we begin to think of mesh sizes and their effect.
Take a herring vinge trawl for example and two other bottom other trawls like the granton trawl and the shrimp trawl. All use otter boards, all are on the sea bed throughout the duration of the tow and all have the same basic structure of wings, square, bellies, bag and cod end. But their performances differ as much as those of a racing car, a truck and a tractor. All three nets could be fishing in the same area, yet the vinge trawl might take only herring, the granton trawl only demersal fish and the shrimp trawl primarily shrimp or prawn. Mesh size has little to do with this species selection. It is a function of other aspects of gear performance - speed of tow, headline height, ground contact, flow of water through the body of the net, otter door spread, length of ground-cables, and so on. The vinge trawl would have the smallest mesh in the cod end, yet it would take no cod, haddock or shrimp. The shrimp or prawn trawl would have a smaller mesh than the granton trawl yet it would capture only a small proportion of the bigger fish the granton trawl would take. To imagine that in these cases the size of mesh controls the size of fish caught would be as simplistic as to think that the respective speeds of the racing car, truck and tractor were determined by the size of their wheels.
In contrast to the trawls designed to capture one species or group of species, there are the multi-species trawls or combination trawls which take a great variety of fish. The North Sea prawn and fish trawl is a combination net designed to capture Nephrops norvegicus or Norway prawns, plus demersal fish like cod, haddock, skate, monks, plaice and lemon sole. Most bottom trawls in the tropics and sub-tropics are multi-species trawls taking fish which vary greatly from each other in size and shape. There is no common selectivity factor and no common minimum size or length for the various species. For these fisheries, a mesh regulation is at best an inadequate means of reducing juvenile mortality. It can be aimed only at the smallest of the main commercial species.
Asian Seabass is a very popular food fish in South Asian countries. This presentation deals with Asian seabass farming in Thailand which includes breeding, larval development, and growout technology. This presentation is a part of my internship work at the Asian Institute of technology.
Aquaculture is the most reliable sector to the providing world nutrias food. It is all depended on the cultivable species. Asian seabass is one of the candidate species for aquaculture because of the wide range of water quality tolerance, growth performance, and consumer preference. The Indian and Western Pacific Oceans are where Asian seabass is found in its natural habitat. It can be cultured in the earthen pond, floating or stationer cages, and recirculating system. Seed resources are available in rivers and lakes of fresh water, but aquaculture is the depending on the hatchery that produces seed because of the superior growth production. In the nursery phase, cannibalism is predominant in Asian seabass cultivation, which will improve via the grading of a shooter. Feeding is one of the important management for good growth performance and reducing cannibalism to give the optimum feed requirements. The growth rate of the Asian seabass is 400-600 g in 4 to 6 months. Asian seabass farmers are suffering from some infectious and non-infection diseases, it will improve via the good management practices of the culture promises. In this review paper, some key points of Asian seabass farming are covered for better understanding.

INTEGRATING SEAWEEED AQUACULTURE TO THE THIRD BIGGEST PORT IN THE UK: AQUACUL...Sara Barrento
ORAL PRESENTATION AQUACULTURE EUROPE 2017
For many years, we have managed our land and sea as isolated components of the total ecosystem. Great investments have been made in the optimization of monocultures systems. Policy and legislation are targeted to manage single use activities within a specific area. But there is now a better understanding and the will to maximize the value from unit area of sea. In this study, we present the first steps towards developing seaweed aquaculture in Milford Haven Port using derelict structures. Milford Haven is the largest trust port in Wales, and the port authority re-invests any profits to support the long-term viability of the port. The Milford Haven Waterway is situated within the Pembrokeshire SAC (Special Area of Conservation), who is responsible for enforcing the EU Habitats Directive.
Recent closure of local oil refinery has created economic hardship and left behind derelict coastal structures. The Milford Haven Port Authority (MHPA) aspires to transform the traditional ‘high carbon’ economy into new ‘low carbon’ economy by developing sustainable aquaculture in the waterway and surrounding grounds. The Port has the infrastructure and welcomes aquaculture businesses – one of the fastest and successful industries worldwide.
In this study, we did a preliminary inventory of unused structures suitable for building a rope platform that would also provide appropriate environmental conditions for seaweed growth. This oral presentation will focus on the challenges and opportunities of growing Saccharina latissima in a Port environment nearby a busy ferry traffic route.
How do fish respond to disturbances by recreational users Sara Barrento
This questionnaire is the result of Charlotte Brockington MSc. Charlotte's project aims to study how fish respond to disturbances by recreation activities such as boating, angling, swimming, cycling, and walking. If fish become habituated to the disturbances from recreational activities, they could then be at risk of predation due to their lack of avoidance behaviours. The information gathered from 230 questionnaires, experiment lab work and literature review will help inform river users management plans. This one year MSc was funded by the KESS2 project in collaboration with Canoe Wales, and Natural Resources Wales.
I collaborated with designers, software developers, and education developers to create not only this job aid but also user manuals and a web-based & desktop application designed to help fish farmers assess and improve the welfare of Lumpfish. You can scan the QR code to access the web-based application.

The Centre for Sustainable Aquatic Research (CSAR) have several industry grade RAS items they wish to donate to further support the development of aquaculture production businesses in Wales. If your aquaculture production business is based in Wales and you would like to benefit some of the items described below, we would like to hear from you.
At the national levels, seaweedaquaculture licensing procedures
need to be simplified for greater cy and efficiency while the social acceptability of seaweed concessions should be promoted. Moreover, it is important for all stakeholders and the whole industry (from policy makers, local authorities, researchers to the production sectors) to have trained
personnel, thus requiring the development of training programmes in regional and/or national centres.
Based on a detailed analysis of current seaweed aquaculture practices, regulations, health benefits and consumer demands, these guidelines aim to foster sustainability and protection of the marine environment. These guidelines also include expert opinions and assessmentsfrom the academic, private
and associative sectors, based mainly in Europe, but also on other continents. With this wide scope and using a field-based and scientific approach, we have aimed to produce a robust prospective reference document to support policy-makers and the elaboration of future European regulations.

First Symposium on Welfare in Aquaculture: Welfare Indicators for Novel Speci...Sara Barrento
Over five hundred and eighty species of aquatic species are farmed globally - most are fish. Lumpfish is a novel marine species to aquaculture and one of the fastest growing farmed fish in Europe. But novel species are challenging - there is little information to guide best practice and as a result this can impact on their welfare. Lumpfish are unique as they are not farmed for human consumption, they provide a service to salmon farmers. Lumpfish are cleaner fish - they clean sealice off salmon. This event aimed to bring to life the 1st Symposium on Welfare in Aquaculture the first edition focused on welfare indicators of novel species. This event explored commonalities and differences in the welfare requirements of different farmed species and asked whether some common welfare metrics exist. The morning symposium was followed by a workshop on lumpfish welfare in the afternoon.

"Understanding the Carbon Cycle: Processes, Human Impacts, and Strategies for...MMariSelvam4
The carbon cycle is a critical component of Earth's environmental system, governing the movement and transformation of carbon through various reservoirs, including the atmosphere, oceans, soil, and living organisms. This complex cycle involves several key processes such as photosynthesis, respiration, decomposition, and carbon sequestration, each contributing to the regulation of carbon levels on the planet.
Human activities, particularly fossil fuel combustion and deforestation, have significantly altered the natural carbon cycle, leading to increased atmospheric carbon dioxide concentrations and driving climate change. Understanding the intricacies of the carbon cycle is essential for assessing the impacts of these changes and developing effective mitigation strategies.
By studying the carbon cycle, scientists can identify carbon sources and sinks, measure carbon fluxes, and predict future trends. This knowledge is crucial for crafting policies aimed at reducing carbon emissions, enhancing carbon storage, and promoting sustainable practices. The carbon cycle's interplay with climate systems, ecosystems, and human activities underscores its importance in maintaining a stable and healthy planet.
In-depth exploration of the carbon cycle reveals the delicate balance required to sustain life and the urgent need to address anthropogenic influences. Through research, education, and policy, we can work towards restoring equilibrium in the carbon cycle and ensuring a sustainable future for generations to come.

UNDERSTANDING WHAT GREEN WASHING IS!.pdfJulietMogola
Many companies today use green washing to lure the public into thinking they are conserving the environment but in real sense they are doing more harm. There have been such several cases from very big companies here in Kenya and also globally. This ranges from various sectors from manufacturing and goes to consumer products. Educating people on greenwashing will enable people to make better choices based on their analysis and not on what they see on marketing sites.

17. Dr Sara Barrento SETTING THE STAGE: WHAT IS PRECISION AQUACULTURE? 5
Sealice are external parasites that feed on the
skin and mucus of the Atlantic salmon
Every year the salmon industry needs 50 million
lumpfish to clean salmon off sea lice
Sea lice impact salmon
Growth
Health
Welfare
18. Dr Sara Barrento SETTING THE STAGE: WHAT IS PRECISION AQUACULTURE? 6
Studies suggest that lumpfish can reduce the use of
anti-sea lice drugs by 80%
The salmon farming industry has
been criticized for not doing
enough to maintain the welfare of
lumpfish.
Concern among consumers
prompted pressure groups to
discourage the use of cleaner
fish until welfare standards are
met.
BUT

43. Sensors for Aquatic Monitoring
Prof. David Gethin OVERVIEW OF PRINTABLE SENSORS 2
Several commercial systems available to
measure key parameters:
1. Temperature (5 - 25°C)
2. pH (6-10)
3. Salinity (0-50pss)
4. Dissolved oxygen (0-20mg/l)
5. Total dissolved solids (0-60g/l)
6. Dissolved organic matter
7. Chlorophyl (0-200µg/l)
8. Turbidity (0-3000NTU)
9. Ionic salts (Nitrates etc)
10. ……. EXO2 Sonde – courtesy Xylem Analytics
Values in brackets are typical, generally commercial sensors have a wider working range
44. Data Capture, Retrieval and Management
Several options available
◦ Hand held from the sonde
◦ Wireless transmission to a receiving portal
◦ Very large data volumes can be generated
Management
◦ Time trend displays
◦ Space variation displays
◦ ……….
◦ Big data analytics
Prof. David Gethin OVERVIEW OF PRINTABLE SENSORS 3
45. The Need for Printable Sensors and Challenges
Commercial systems are accurate, but high cost
◦ Sonde + sensors – typically £20k
◦ Prevents widespread monitoring of aquatic environments
Printable sensors
◦ Offer potential for lower cost solutions
◦ Sensors to measure a range of parameters may be fabricated as an integrated system
Challenges
◦ Measurement accuracy – calibration against laboratory and commercial devices
◦ Survival in a harsh environment
◦ Working duration
Prof. David Gethin OVERVIEW OF PRINTABLE SENSORS 4
46. Potential Printed Sensors
1. Temperature (5 - 25°C)
2. pH (6-10)
3. Salinity (0-50pss) – via conductivity
4. Dissolved oxygen (0-20mg/l)
5. Total dissolved solids (0-60g/l) – via conductivity and temperature
Remaining parameters may be measured by optical methods (being developed
by Waterford)

83. Performance of monitoring equipment
Tidbits, tide gauges- no issues, long life reliable, low cost- can be lost. Good
value for money.
CT/CTD’s- give more information, fairly reliable, can suffer from fouling/clogging
and can get lost. Good value for money.
Datasondes (4a/5X’s). Spikey chlorophyll data/error readings. DO fluorescence
excellent. Fouling, critters living in the housing near sensors. Cost of units and
calibration is high. Spot reading hand held unit very good. Power drain when
sensor fails.
Current meters (Aandera). Extremely reliable data and robust (If only everything
in life was as reliable!). Costly. Have had a tractor drive over one and a dredger
drag one off its location. Can do spot readings from boat too with inline frame
(not live readings).
Brian O’Loan SHELLFISH AQUACULTURE AND SENSOR DEPLOYMENT IN THE SOUTHEAST OF IRELAND 25
84. Pressures/Concerns
E. coli shellfish classification ( B classification or better essential for industry) (Mussels and Oysters)
◦ WWTP’s
◦ Stormwater Overflows
◦ Pumping Station failures
◦ Agriculture
◦ Septic tanks
◦ The combination of pressures will vary from bay to bay.
Norovirus levels more of a concern for oyster industry
◦ Human sources (WWTP’S, Stormwater Overflows, Pumping Station Failures), Septic tanks
◦ Sales to Asian lucrative markets depends on very stringent levels for Norovirus.
◦ Depuration required but sometimes Norovirus can be too high for depuration to work fully.
Excessive Mortalities
◦ Microbial Causes (Herpes, Vibrio)
◦ Algal blooms (Oxygen/Toxins)
◦ Unknown causes?
Brian O’Loan SHELLFISH AQUACULTURE AND SENSOR DEPLOYMENT IN THE SOUTHEAST OF IRELAND 26
85. What the Shellfish Industry wants
Real Time Monitoring with alarms/notifications.
Year round monitoring but late spring to early autumn essential (I focus on June-September)
Better spread of monitoring locations (production areas are big)
More monitoring close to point pressures eg WWTP/Stormwater Overflows/Industrial
Discharges
Different priorities for each bay e.g. Impact of Chlorine Produced Oxidants on ecosystem and
turbidity monitoring.
Dissolved Oxygen crucial.
E. coli/Norovirus. Can sensors be developed to detect in the field?
Cheaper sensors.
Brian O’Loan SHELLFISH AQUACULTURE AND SENSOR DEPLOYMENT IN THE SOUTHEAST OF IRELAND 27
86. 3 Take home messages:
Requirement for monitoring shifting more towards protection of shellfish
Realtime data(preferably with notifications) is strongly desired by industry
Requirement for cheaper sensors and monitoring of new parameters over
greater area

As with many RAS facilities, CSAR makes use of
probes to monitor and adjust the following
parameters:
• Air temp, Water temp
• Salinity
• pH
• Oxygen levels
• CO2 levels
• Ozone
• Flow rates
• Tank depth
In addition, all probes are linked to a central
alarm system which includes hardware failure
backup
How can the current sensor tech in the sector
be enhanced?

REVERSE ENGINEERING:
A MACHINE VISION SOLUTION FOR AQUACULTURE
• Machine Vision
• Industry questions
• In this presentation
1. Where do the fish go?
2. Can clinging and swimming behavior be identified?
REVERSE ENGINEERING: A MACHINE VISION SOLUTION FOR AQUACULTURE
119. 1. Where do
the fish go?
Adrian Hodgkinson REVERSE ENGINEERING: A MACHINE VISION SOLUTION FOR AQUACULTURE 3
Faptic.xyz
Start from:
• visual representation
Gives insight:
• fish behaviour
• distributionin the watervolume
Indicates:
• e.g. fish aggregating to the surface can suggest low oxygen level
120. The process in reverse:
7. record underwater videosand detect fish in frames
6. define the position of individual fishin 3D space - (x, y, z) coordinates
5. distributethe total volume in small units
4. calculatethe number of fish inside unit volumes
3. calculatethe averagefish number in each unit
2. define a threshold for critical fish density
1. visualize the results

121. Employing machine vision
DETECT FISH DEFINE POSITION IN 3D
Stereoscopicimages are used in the
recordings.
We can calculate the (x, y, z) coordinates
of the detected fish.
We can visualize the position of the fish
inside the tank.

• AI - Deep Learning algorithms
• Fish position in the image 2D
(pixel coordinates)
122. Simplifying the results
DIVIDETHE TOTAL VOLUME FISH IN UNIT VOLUMES
Adrian Hodgkinson REVERSE ENGINEERING: A MACHINE VISION SOLUTION FOR AQUACULTURE 6
Faptic.xyz
• distribute the totalvolume in small units–
50x50x50 m units
u_x, u_y, u_z = 50, 50, 50
units_x = int((x_max-x_min)/u_x)
units_y = int((y_max-y_min)/u_y)
units_z = int((z_max-z_min)/u_z)
• Unit volumes are determined by the coordinates
of the vertices.
• The positionsof the fish are known.
• Counting the number of fish, when its positionis
inside the unit volume
(e.g. [25, 20, 36, 14, 22, …])
[[-100,-100,-100],
[-50, -100, -100],
[-50, -50, -100],
[-100, -50, -100],
[-100,-100,-50],
[-50, -100, -50],
[-50, -50, -50],
[-100, -50, -50]]
123. Simplifying the problem
AVERAGEFISH DENSITY IN UNIT VOLUME
- save historical data about counts
inside unit volumes
- calculate the average number for a
given period (e.g. 20 min)
- mark visually if the number of fish is
high in a specific part of the water

125. The process in reverse:
7. record underwater videosand track fish in frames
6. define the initialpositionof fish where the centroid shows up
5. in next frames identify again the fish/fishes positionand compare with previousone
4. fish swimming : compare new positionof lumpfish
with last position , if not equal -> lumpfish moves
3. fish clinging : compare new positionof lumpfish
with last position , if equal -> lumpfish doesn't move
2. count fish swimming and fish clinging
1. visualize the results

128. Clinging vs swimming behaviour
Adrian Hodgkinson REVERSE ENGINEERING: A MACHINE VISION SOLUTION FOR AQUACULTURE 12
Estimating behaviourtypes:
• Fish swimming:
Previous positionof fish detected is not equalto the new position.
• Fish clinging:
Previous position of fish detected is equal to the new position.
Example for distinguishingbehaviour:
Lumpfish 9 : in initialframe was found at 28.33 pixels and next frames the same at 28.33 = lumpfish clinging
Lumpfish 11: in initialframe was found at 31.59 pixels and next frames at 25.74 = lumpfish swimming
We represent an examplein the following images.
