This slide deck defines this remarkable development, highlighting the opportunity that's sure to place stakeholders at the forefront of a market shift. To Appreciate the Magnitude of our extraordinary development, we must first paint the picture of an industry that's responsible for producing a food product that’s prized in every corner of the globe, regardless of socioeconomic standing, religious belief, or geographical location. We’ll look at the good, bad, and ugly, as it is today, and show you how the significance of our story stands to change everything. The Good The United States Loves Shrimp Consumptive shrimp is one of the most sought-after foods in the world. Americans alone consume more than one billion pounds of shrimp annually, making this by far the most popular seafood for consumption in the United States. According to the World Wildlife Federation, "Shrimp is the most valuable traded marine product in the world today. In 2005, farmed shrimp was a $10.6 Billion industry.” Today, the global shrimp farming industry has grown by nearly 325% in 15 years to about $45 Billion. The Bad America Doesn’t Produce Enough Up to and until now, the United States had no method for producing enough shrimp to satisfy the appetite of the American Consumer.

[email protected] Central Marine Fisheries Research Institute, Kochi - 18 Mariculture of finfish on a commercial scale is non-existent in India. CMFRI, RGCA of MPEDA, CIBA are the Institutions promoting finfish mariculture with demonstrated seed production capabilities of Asian seabass (Lates calcarifer), cobia (Rachycentron canadum) and silver pompano (Trachynotus blochii). Seed production is not sufficient enough togo in for commercial scale investment. Requisite private investment has not flown into this segment of aquabusiness and Public Private Partnerships (PPP) are yet to take off. The scenario being this in the case of one (seed) of the two major inputs in this food production system, feeds and feeding, which is the other is the subject of elaboration here. Quality marine fish like king seer, pomfrets and tuna retails at more than Rs.400/- per kg in domestic markets. In metro cities it Rs.1000/- per kg is not surprising. With this purchasing power in the domestic market, most of the farmed marine fish is sold to such a clientele which is ever increasing in India. Therefore, without any assurance of a sustainable supply of such fish from capture fisheries, there is no doubt that we have to farm quality marine fish. With as deficit in seed supply at present, let us examine nutrition, feeds and feed technology required for this farming system in India. Farming sites, technologies of cage fabrication and launch, day-to-day management, social issues, policy, economics and health management, harvest and marketing, development of value chains, traceability and certification are all equally important and may or may not be dealt with in this training programme.

  • Fishery Basics – Seafood Markets Types of Fishery Products
    Fishery Basics – Seafood Markets Types of Fishery Products Fish products are highly traded and valuable commodities around the world. Seafood products are high in unsaturated fats and contain many proteins and other compounds that enhance good health. Fisheries products can be sold as live, fresh, frozen, preserved, or processed. There are a variety of methods to preserve fishery products, such as fermenting (e.g., fish pastes), drying, smoking (e.g., smoked Salmon), salting, or pickling (e.g., pickled Herring) to name a few. Fish for human consumption can be sold in its entirety or in parts, like filets found in grocery stores. The vast majority of fishery products produced in the world are intended for human consumption. During 2008, 115 million t (253 billion lbs) of the world fish production was marketed and sold for human consumption. The remaining 27 million t (59 billion lbs) of fishery production from 2008 was utilized for non-food purposes. For example, 20.8 million t (45 billion lbs) was used for reduction purposes, creating fishmeal and fish oil to feed livestock or to be used as feed in aquaculture operations. The remainder was used for ornamental and cultural purposes as well as live bait and pharmaceutical uses. Similar to the advancement of fishing gear and navigation technology (See Fishing Gear), there have been many advances in the seafood-processing sector over the years. Prior to these developments, most seafood was only available in areas close to coastal towns. The modern canning process originated in France in the early 1800s. Cold storage and freezing plants, to store excess harvests of seafood, were created as early as 1892.

  • Fishery Oceanographic Study on the Baleen Whaling Grounds
    FISHERY OCEANOGRAPHIC STUDY ON THE BALEEN WHALING GROUNDS KEIJI NASU INTRODUCTION A Fishery oceanographic study of the whaling grounds seeks to find the factors control­ ling the abundance of whales in the waters and in general has been a subject of interest to whalers. In the previous paper (Nasu 1963), the author discussed the oceanography and baleen whaling grounds in the subarctic Pacific Ocean. In this paper, the oceanographic environment of the baleen whaling grounds in the coastal region ofJapan, subarctic Pacific Ocean, and Antarctic Ocean are discussed. J apa­ nese oceanographic observations in the whaling grounds mainly have been carried on by the whaling factory ships and whale making research boats using bathyther­ mographs and reversing thermomenters. Most observations were made at surface. From the results of the biological studies on the whaling grounds by Marr ( 1956, 1962) and Nemoto (1959) the author presumed that the feeding depth is less than about 50 m. Therefore, this study was made mainly on the oceanographic environ­ ment of the surface layer of the whaling grounds. In the coastal region of Japan Uda (1953, 1954) plotted the maps of annual whaling grounds for each 10 days and analyzed the relation between the whaling grounds and the hydrographic condition based on data of the daily whaling reports during 1910-1951. A study of the subarctic Pacific Ocean whaling grounds in relation to meteorological and oceanographic conditions was made by U da and Nasu (1956) and Nasu (1957, 1960, 1963). Nemoto (1957, 1959) also had reported in detail on the subject from the point of the food of baleen whales and the ecology of plankton.

NAIR Central Institute of Fisheries Technology, Coct)in - 682 029. ABSTRACT There are good possibilities for expanding the consumer sector in both the traditional and nontraditional marine products. Frozen shrimp continues to be the item of highest demand in foreign markets. Individual quick frozen (IQF) prawns which are indeed value added products and have already penetrated international markets elicit export incentive from development agencies like the Marine Products Export Development Authority. With the projected potential of 1.8 lakh tonnes of cephalopods against the current yield . of 13,000 tonnes, there are good prospects of increasing exports of frozen &;JUid and cuttlefish. The technology of packing fish in retortable pouches as an alternative to canning has now been perfected. Salted fish mirice has good market potential within the country and abroad. Diversification of fish products which are acceptable to larger fish consuming communities would alone ensure profitable utilization of our marine resources. INTRODUCTION India's total marine fish ·landings amount to 1.53 million metric tonnes against the harvestable resource of 4. 5 million ton nes projected potential. Of the landings, just over 65% are con­ sumed in fresh condition, about 20% converted· into salted and dried products, 4% reducted into fish meal and 7% made into frozen products which almost exclusively go for export purpose.

  • Resources for Fish Feed in Future Mariculture
    Vol. 1: 187–200, 2011 AQUACULTURE ENVIRONMENT INTERACTIONS Published online March 10 doi: 10.3354/aei00019 Aquacult Environ Interact OPENPEN ACCESSCCESS AS I SEE IT Resources for fish feed in future mariculture Yngvar Olsen* Trondhjem Biological Station, Department of Biology, Norwegian University of Science and Technology, 7491 Trondheim, Norway ABSTRACT: There is a growing concern about the ability to produce enough nutritious food to feed the global human population in this century. Environmental conflicts and a limited freshwater supply constrain further developments in agriculture; global fisheries have levelled off, and aquaculture may have to play a more prominent role in supplying human food. Freshwater is important, but it is also a major challenge to cultivate the oceans in an environmentally, economically and energy- friendly way. To support this, a long-term vision must be to derive new sources of feed, primarily taken from outside the human food chain, and to move carnivore production to a lower trophic level. The main aim of this paper is to speculate on how feed supplies can be produced for an expanding aquaculture industry by and beyond 2050 and to establish a roadmap of the actions needed to achieve this. Resources from agriculture, fish meal and fish oil are the major components of pellet fish feeds. All cultured animals take advantage of a certain fraction of fish meal in the feed, and marine carnivores depend on a supply of marine lipids containing highly unsaturated fatty acids (HUFA, with ≥3 double bonds and ≥20 carbon chain length) in the feed. The availability of HUFA is likely the main constraint for developing carnivore aquaculture in the next decades.

Mariculture has been contributing substantially to the global fish production in recent years. It accounted for about 29.2 per cent of world aquaculture production by value. It is a fact that India is still in infancy in mariculture production in the global scenario. Since mariculture is the only hope for increasing seafood production in the coming years, the research and development in this sector is of paramount importance. In fact, such thrust was not given in India and hence, it was felt necessary to develop viable seed production and farming technologies to develop mariculture. The R&D efforts in this direction yielded commendable results within a few years and Mandapam Regional Centre of ICAR CMFRI succeeded in captive breeding and seed production of two high value marine fishes namely, Cobia, Rachycentron canadum and Silver pompano, Trachinotus blochii for the first time in the country.
