RECENT PROGRESS of crustacean nutrition

S. Koshio

Studies on crustacean nutrition have been progressed a lot past few years due to the high pressure on the important issues in aquaculture industry, such as environmental deteriorations, fishmeal shortage, disease outbreak etc.

In species category, Litopenaeus vannamei has become very popular in the literature due to the production increase in Asian and Latin American countries, following by Penaeus monodon, Marsupenaeus japonicus, Macrobrachium rosenbergii, Cherax quadricarinatus, and others.

Several potential alternative protein sources for fishmeal have been suggested such as canola meal, pea meal, lupin meal, peanut meal, soybean meal, soybean poultry by-product meal, squid protein and so on. In amino acid studies, the new coating method for protection of the leaching was reported. Studies on cholesterol, lecithin or phospholipids, fatty acids, triolein, cholestane have been conducted qualitatively and quantitatively using penaeid shrimps, crayfish and lobsters. The role of fiber or cellulose has also been investigated using freshwater species such as Macrobrachium and Cherax.

Nutrition and immunology have been paid attention recent years. There are several studies on the improvement of immunological condition of crustaceans by applying immuno-stimulants and micronutrients such as vitamins and fatty acids, and probiotics.

In this presentation, selective topics above are reviewed including larval studies of crustaceans.
