Biosecurity protocols needed for shrimp feeds, feeding practices « Global Aquaculture Advocate

Aquaculture is a fast-growing sector of livestock production, but has attracted criticism owing to the practice of using marine ingredients as feed, usually in the form of fishmeal and fish oil. This is followed by a survey of the current trends in the production of fishmeal and fish oil from raw materials of marine origin and of the changing pattern of inclusion in aquaculture feeds, as well as their use in land animal feeds and human nutritional products. Particular attention is paid to the substitution of marine feed ingredients by vegetable proteins and oils and by recycled land animal products in aquaculture diets. A global input and output analysis indicates that there is a substantial net production of fish owing to use of marine ingredients for aquaculture feed and that continuing future growth of aquaculture is unlikely to threaten stocks of wild fish currently used for reduction. This counters a principal criticism of using marine ingredients. It is concluded that future growth of fed aquaculture will be associated with proportionately greater use of land animal and plant proteins, oils and carbohydrate sources, and with a continuing decline in depend- ence on marine ingredients.

Aquaculture: are the criticisms justified? Feeding fish to fish

The cultured shrimp sector is one of the most profitable in the global aquaculture industry. Despite its global importance, the shrimp farming industry has suffered a number of important disease outbreaks that have caused significant economic losses over the last several years. Other land-based, meat-producing industries have developed in the same manner, so the shrimp farming sector can benefit from their learning curves regarding the development and implementation of biosecurity protocols as it continues to expand global shrimp production. The use of formulated shrimp aquafeeds is an important component of and a significant reason why the shrimp farming industry has developed so successfully and essentially quadrupled global production in the last three decades. Biosecure shrimp feeds and on-farm feeding strategies involve all aquafeeds live, fresh or formulated and their management at every component of the shrimp production value-chain.
