Status of aquaculture with respect to nutrition and feedAuthor(s):
Aquaculture is basically rearing of aquatic animals, majorly fishes. Fish is very important animals and considered as a poor man protein food due to its lesser price. Fish consumers are greatly increasing with the current annual per capita consumption of 20/Kg. From the past 50 years, around 90% of the fish populations were destroyed by commercial fishing as fishermen use massive ships, innovative electronic equipment and satellites to find the fish for fishing. It is imperative to note that some areas due to low catch, fishermen are finding alternate jobs for their livelihood. According to FAO, there was a steep growth in the aquaculture industry for the last seven decades as the dependence of capture fishery for fish has greatly reduced. In that sense, only by capture fishery it is really difficult to meet the protein requirement to the human population; thus, aquaculture is now playing a substantial role. In aquaculture, profitability relies on the production of healthy fish which require quality ingredients and diets. Also, the performance and growth of aquaculture industry will greatly affect by feed costs as they constitutes around 50 to 60% of the total operating cost and therefore, fish nutrition and feed research are expected from these areas. The nutritional research encompasses the study of nutrients necessary for the maintenance of life. While the feed research covers the study on the preparation of quality ingredients which yield nutrients needed for the growth and performances of the animals. At present, works on fish feed nutrition is concentrated on the following areas: the nutrient requirements for larval, adult and broodstock fishes; metabolic role of each nutrients on growth and reproduction; manufacturing of artificial feed using low cost unconventional feedstuffs replacing with costliest conventional feed ingredients; identification of feed additives to improve the metabolism and growth; formulation of the standard feeds using quality and low polluting nutrients. The present paper discusses the challenges and scope of aquaculture industry in relation to nutrition and feed; but special attention has given to the aforementioned areas.Pages: 333-345 | 1766 Views 141 DownloadsDownload Full Article:
