Nutritional requirement of cultivable fin fish: larvae, juveniles and adultsDebiprasad1997
Fish is among the healthiest foods on the planet. It is loaded with important nutrients, such as protein and vitamin D. Fish is also the world's best source of omega-3 fatty acids, which are incredibly important for human body and brain.
Manufactured feeds are an important part of modern commercial aquaculture, providing the balanced nutrition needed by farmed fish.
In the development of modern aquaculture, starting in the 1970s, fishmeal and fish oil were key components of the feeds for these species. They are combined with other ingredients such as vegetable proteins, cereal grains, vitamins and minerals and formed into feed pellets.
The global supply of fish meal and fish oil is finite and fully utilized. Alternative or nontraditional feedstuffs may differ in terms of taste, smell, texture, and color, as well as nutrient composition, from the traditional feedstuffs, which are produced largely from the natural prey of the fish being raised. Alternative feedstuffs may also contain compounds and antinutritional factors that affect digestive or sensory physiology.
Another important area of fish nutrition for the next 20 years will be larval fish nutrition. Currently, the cost and difficulty of rearing a great number of species from the first feeding to the juvenile stage are the most severe bottlenecks to the development of aquaculture production of nontraditional species.

CAGE CULTURE OF FISH THEIR TREND,STATUS AND PRODUCTION Ashish sahu
Cage culture is an aquaculture production system where fish are held in Cage. Cage culture of fish utilizes existing water resources but encloses the fish in a cage which allows water to pass freely through the enclosures and the surrounding water body. Cages are used to culture several types of shell fish and finfish species in fresh, brackish and marine waters. Cages in freshwaters are used for food fish culture and for fry to fingerling rearing.
In 1950s modern cage culture began with the initiation of production of synthetic materials for cage construction. Fish production in cages became highly popular among the small or limited resource farmers who are looking for alternatives to traditional agricultural crops. The mesh size of the cage is kept smaller than the fish body. In India cage culture have been attempted first for Air breathing fish. Cage mesh netting made from synthetic material that can resist decomposition in water for a long period of time. Cage are used to culture several type of shell fish and fin fishes in fresh , brackish and marine water. Cage in fresh water are used for food fish culture and for fry to fingerling rearing. Cages are generally small, ranging in freshwater reservoirs from 1 square meter (m2) to 500 m2.

Cage culture is a system in which the cultured Fish 0r animal are enclosed from all side allowing water to pass freely through the enclosures and the surrounding water body.
HISTORY-
Cage culture seem to have developed around 200 year ago in Cambodia where fisherman used to keep clarias spp. And some other fishes in bamboo made cage. Cage culture is traditional in part of Indonesia also attempted for the first time in air breathing fishes in swamp for raising major carp in running water in the river, Yamuna and Ganga at Allahabad and for raising Common carp , Catla , Silver carp, Rohu , Snakehead and Tilapia in still water body of Karnataka. In India sea cage start in 2007 for culture sea bass at Vishakhapatnam by CMFRI. anchored in streams which are practically open sewers. Common carp , where cage are in the southern USA. Around 80 species are being culture in cage. In India cage culture was initially culture in bamboo cage is practice in west java, since early 1940. Modern cage culture in open water bodies probably originated in Japan in early 1950. According to FAO cage culture is being practiced in more than 62 countries and has a become high tech business in developed countries such as floating and submerged cage culture of Salmonids in Norway, Canada and Scotland, Tuna and Yellowtails in Japan , Chinese carp in China, and catfish.

Broodstock And Hatchery Management Of Penaeus Monodonsush_p
Shrimp aquaculture is an important and valuable production sector that has been growing rapidly over the past two decades. Success is largely based on the quality of post larvae, particularly their health condition, thus making hatchery production of quality post larvae crucial to the sector’s sustainability. Vietnam is the leading producer of black tiger shrimp in the world with a production of 300,000 tons in 2011, followed by India and Indonesia with a production of 187,900 tons and 126,200 tons respectively.
Major contribution of the tiger shrimp to global shrimp production and the economic losses resulting from disease outbreaks, it is essential that the shrimp-farming sector invest in good management practices for the production of healthy and quality seed. The Indian shrimp hatchery industry has established a detailed guidance and protocols for improving the productivity, health management, biosecurity and sustainability of the sector. Following a brief review of shrimp hatchery development in India, the major requirements for hatchery production are discussed under the headings: infrastructure, facility maintenance, inlet water quality and treatment, wastewater treatment, biosecurity, standard operating procedures (SOPS), the Hazard Analysis Critical Control Point (HACCP) approach, chemical use during the hatchery production process and health assessment. Pre-spawning procedures include the use of wild, domesticated and specific pathogen free/ specific pathogen resistant (SPF/SPR) broodstock, broodstock selection and holding techniques, transport, utilization, health screening, maturation, nutrition and spawning, egg hatching; nauplius selection, egg/ nauplius disinfection and washing and holding, disease testing and transportation of nauplii. Post-spawning procedures include: larval-rearing unit preparation, larval rearing/health management, larval nutrition and feed management, important larval diseases, quality testing/selection of PL for stocking, PL harvest and transportation, nursery rearing and record keeping.

Whiteleg shrimp (Litopenaeus vannamei, formerly Penaeus vannamei), also known as Pacific white shrimp or King prawn, is a variety of prawn of the eastern Pacific Ocean commonly caught or farmed for food.L. vannamei is a decapod crustacean which is native to the Eastern Pacific Coast of Central and
South America from Tumbes, Peru in the south to Mexico in the north. It has been introduced widely around the world since the 1970s, but especially since 2000, as it has become the principle
cultured shrimp species in Asia. The species itself is not considered a major threat to biodiversity, does not appear to have formed breeding populations, and has generally resulted in positive economic impacts in non-indigenous areas. An examination of current lists of invasive species
published by the International Union for Conservation of Nature’s Invasive Species Specialist Group (IUCN, 2004) revealed no listings for L. vannamei. As mentioned, L. vannamei has been anthropogenically introduced as an aquaculture species to several areas of the world to which it is
not native.

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

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.

Operation “Blue Star” is the only event in the history of Independent India where the state went into war with its own people. Even after about 40 years it is not clear if it was culmination of states anger over people of the region, a political game of power or start of dictatorial chapter in the democratic setup.
The people of Punjab felt alienated from main stream due to denial of their just demands during a long democratic struggle since independence. As it happen all over the word, it led to militant struggle with great loss of lives of military, police and civilian personnel. Killing of Indira Gandhi and massacre of innocent Sikhs in Delhi and other India cities was also associated with this movement.
