Modern developments in transport technology are from two levels; one is from an understanding of internal physiological mechanisms of the fish and the optimal requirements, ensuring maximum survival of fish under transport and the other is from a study of the environmental parameters of the medium in which fish are transported. Under anaesthesia fish can be transported without water even, provided the skin and gills are kept moist under low temperature. The cryopreservation of fish sperm for use at any convenient time can be referred to here, though this would concern seed production more directly than live seed transport.
Fish culture is classified based on the number of fish species as monoculture and polyculture. This is the culture of single species of fish in a pond or tank. The culture of trout, tilapia, catfish , carps are typical examples of monoculture.
The principle of integrated fish farming involves farming of fish along with livestock or/and agricultural crops.. This type of farming offers great efficiency in resource utilization, as waste or by product from one system is
effectively recycled. It also enables effective utilization of available farming space for maximizing production.
•The rising cost of protein-rich fish food and chemical fertilizers
as well as the general concern for energy conservation have created awareness in the utilization of rice and other crop fields and livestock wastes for fish culture. Fish culture in combination with agriculture or livestock is a unique and lucrative venture and provides a higher farm income, makes available a cheap source of protein for the
rural population, increases productivity on small land-holdings
and increases the supply of feeds for the farm livestock.
Scope of Integrated Fish Farming
The scope of integrated farming is considerably
wide. Ducks and geese are raised in pond, and pond- dykes are used for horticultural and agricultural
crop products and animal rearing.
The system provides meat, milk, eggs, fruits,
vegetables, mushroom, fodder and grains, in
addition to fish.
Hence this system provides better production, provides more employment, and improves socio- economic status of farmers and betterment of rural economy.
Classification of Integrated Fish Farming
Integrated fish farming can be broadly classified into two, namely Agriculture-fish and Livestock-fish systems
Agriculture-fish systems- Agri-based systems include rice-fish integration,
horticulture-fish system, mushroom- fish system, seri-fish system.
Livestock-fish systems- Livestock-fish system includes cattle-fish system, system, pig-fish system, poultry-fish system, duck-fish system, goat-fish system, rabbit-fish system.

With the emerging concern on environmental cost more specifically greenhouse gas emission related with conventional livestock rearing for meat has come to a problematic situation. Therefore, animal scientists and human nutritionists collectively try to develop a new trend of rearing non-conventional livestock for meat purposes. Some of the non conventional species are already being exploited to commercial levels. This presentation attempts to discuss some key points about non conventional livestock in a brief and simple manner.
Mealworm as a sustainable Feed resourceSarzamin Khan
Meal Worm as a source of Poultry and animal feed is a strong candidate to cater the Future need in Changing Global Climate. The presentation describes the importance and production of meal worm.
Fish- livestock farming systems are recognized as highly assured technology where predetermined quantum of livestock waste obtained by rearing the live stock in the pond area is applied in pond to raise the fish crop without any other additional supply of nutrients. The main potential linkages between livestock and fish production concern use of nutrients, particularly reuse of livestock manures for fish production. The term nutrients mainly refer to elements such as nitrogen (N) and phosphorus (P) which function as fertilizers to stimulate natural food webs rather than conventional livestock nutrition usage such as feed ingredients. Both production and processing of livestock generate by-products that can be used for aquaculture. Direct use of livestock production wastes is the most widespread and conventionally recognized type of integrated farming. Production wastes include manure, urine and spilled feed; and they may be used as fresh inputs or be processed in some way before use.
Based on the type of livestock used for integration there are many combinations in livestock-fish systems. Some of the combination are listed and discussed below.
Cattle-Fish Culture
Manuring of fish pond by using cow dung is one of the common practices all-over the world. A healthy cow excretes over 4,000-5,000 kg dung, 3,500-4,000 lt urine on an annual basis. Manuring with cow dung, which is rich in nutrients results in increase of natural food organism and bacteria in fishpond. A unit of 5-6 cows can provide adequate manure for 1 ha of pond. In addition to 9,000 kg of milk, about 3,000-4,000 kg fish/ha/year can also be harvested with such integration.
Cowshed should be built close to fishpond to simplify handling of cow manure. A cow requires about 7,000-8,000 kg of green grass annually. Grass carp utilizes the left over grasses, which are about 2,500 kg. Fish also utilize the fine feed which consists of grains wasted by cows. In place of raw cow dung, biogas slurry could be used with equally good production. Twenty to thirty thousand kg of biogas slurry are recycled in 1 ha water area to get over 4000 kg of fish without feed or any fertilizer application.
Pig-Fish system
The waste produced by 30-40 pigs is equivalent to 1 tonne of ammonium sulphate. Exotic breeds like White Yorkshire, Landrace and Hampshire are reared in pig-sty near the fish pond. Depending on the size of the fishponds and their manure requirements, such a system can either be built on the bund dividing two fishponds or on the dry-side of the bund. Pigsties, however, may also be constructed in a nearby place where the urine and dung of pigs are first allowed to the oxidation tanks (digestion chambers) of biogas plants for the production of methane for household use. The liquid manure (slurry) is then discharged into the fishponds through small ditches running through pond bunds. Alternately, the pig manure may be heaped in localized places of fishponds or may be applied in fishponds.
Plant Power vs Power Plant by Sena Crutchley (PAVE)VegFund
The Piedmont Area Vegan Educators (PAVE) have developed an informative presentation titled “Plant Power vs Power Plant: What We Consume and the Environment,” which they’ve used as the basis for talks with local environmental organizations. The presentation clearly and concisely lays out the facts and issues of our food and lifestyle choices and their relationship to the environment. PAVE graciously agreed to share it with the VegFund community as a valuable resource for all vegan advocates.

Embracing GenAI - A Strategic ImperativePeter Windle
Artificial Intelligence (AI) technologies such as Generative AI, Image Generators and Large Language Models have had a dramatic impact on teaching, learning and assessment over the past 18 months. The most immediate threat AI posed was to Academic Integrity with Higher Education Institutes (HEIs) focusing their efforts on combating the use of GenAI in assessment. Guidelines were developed for staff and students, policies put in place too. Innovative educators have forged paths in the use of Generative AI for teaching, learning and assessments leading to pockets of transformation springing up across HEIs, often with little or no top-down guidance, support or direction.
This Gasta posits a strategic approach to integrating AI into HEIs to prepare staff, students and the curriculum for an evolving world and workplace. We will highlight the advantages of working with these technologies beyond the realm of teaching, learning and assessment by considering prompt engineering skills, industry impact, curriculum changes, and the need for staff upskilling. In contrast, not engaging strategically with Generative AI poses risks, including falling behind peers, missed opportunities and failing to ensure our graduates remain employable. The rapid evolution of AI technologies necessitates a proactive and strategic approach if we are to remain relevant.

The French Revolution, which began in 1789, was a period of radical social and political upheaval in France. It marked the decline of absolute monarchies, the rise of secular and democratic republics, and the eventual rise of Napoleon Bonaparte. This revolutionary period is crucial in understanding the transition from feudalism to modernity in Europe.

June 3, 2024 Anti-Semitism Letter Sent to MIT President Kornbluth and MIT Cor...Levi Shapiro
Letter from the Congress of the United States regarding Anti-Semitism sent June 3rd to MIT President Sally Kornbluth, MIT Corp Chair, Mark Gorenberg
Dear Dr. Kornbluth and Mr. Gorenberg,
The US House of Representatives is deeply concerned by ongoing and pervasive acts of antisemitic
harassment and intimidation at the Massachusetts Institute of Technology (MIT). Failing to act decisively to ensure a safe learning environment for all students would be a grave dereliction of your responsibilities as President of MIT and Chair of the MIT Corporation.
This Congress will not stand idly by and allow an environment hostile to Jewish students to persist. The House believes that your institution is in violation of Title VI of the Civil Rights Act, and the inability or
unwillingness to rectify this violation through action requires accountability.
Postsecondary education is a unique opportunity for students to learn and have their ideas and beliefs challenged. However, universities receiving hundreds of millions of federal funds annually have denied
students that opportunity and have been hijacked to become venues for the promotion of terrorism, antisemitic harassment and intimidation, unlawful encampments, and in some cases, assaults and riots.
The House of Representatives will not countenance the use of federal funds to indoctrinate students into hateful, antisemitic, anti-American supporters of terrorism. Investigations into campus antisemitism by the Committee on Education and the Workforce and the Committee on Ways and Means have been expanded into a Congress-wide probe across all relevant jurisdictions to address this national crisis. The undersigned Committees will conduct oversight into the use of federal funds at MIT and its learning environment under authorities granted to each Committee.
• The Committee on Education and the Workforce has been investigating your institution since December 7, 2023. The Committee has broad jurisdiction over postsecondary education, including its compliance with Title VI of the Civil Rights Act, campus safety concerns over disruptions to the learning environment, and the awarding of federal student aid under the Higher Education Act.
• The Committee on Oversight and Accountability is investigating the sources of funding and other support flowing to groups espousing pro-Hamas propaganda and engaged in antisemitic harassment and intimidation of students. The Committee on Oversight and Accountability is the principal oversight committee of the US House of Representatives and has broad authority to investigate “any matter” at “any time” under House Rule X.
• The Committee on Ways and Means has been investigating several universities since November 15, 2023, when the Committee held a hearing entitled From Ivory Towers to Dark Corners: Investigating the Nexus Between Antisemitism, Tax-Exempt Universities, and Terror Financing. The Committee followed the hearing with letters to those institutions on January 10, 202

3. Semi intensive system Semi intensive fish culture system is more prevalent and
involves rather small ponds(0.5 to 1 hectare in an area) with
higher stocking density (10000 to 15000 fish/ha).
Basically in this system care is taken to develop naturals
foods by fertilization with/without supplemental feeding.
However the major food source is natural food
Yield is moderate (3 to 10 ton/ha) and survival rate is high.
4. Why Semi intensive culture system
is preferred
.Low cost more production
Comparatively cleaner system as compared with
extensive culture system
More fishes can be reared in natural ponds
7. Selection of supplementary
Feed
Use the feed stuff that are of
Good nutritional values with high protein
and carbohydrates and low fiber
Well accepted by the fish we want to feed
Cheap in price
Available easily most of fish growing
season
8. Materials that can be used as
feed supplement
Small animals:Earthworms , Snails and
Termites
Plant materials:Grasses legumes leaves
seeds fruits and vegetables
Kitchen :wastes
Brewery; Wastes and yeasts
Manures; chicken dropping pig manure
etc
Rice; Broken polishing bran
9. How fine feed stuff should be
Adopt the size of feed stuff particles to the mouth size
of the fish to reduce feed loss and maximize feed
utilization
10. Stocking density of fish in semi
intensive culture
The stocking density of fish ponds describes the
number of fish that are stocked initially per unit area.
It is one of the most important factors in determining
the production of fish farm.
At low levels ,increased the stocking density will
increase yeild.
