Peas (Pisum sativum) are one of the four most important crops next to soybean, groundnut, and beans. It is a particularly important legume in temperate areas with numerous food (dry seed, vegetable) and feed (seed, fodder) usages.

Field peas have attracted considerable attention as an animal feed due to increased production in Europe and Canada and thus reliable supply and competitive price. Pea seed meal has been trialled in Atlantic salmon, Rainbow trout and European sea bass with encouraging results.

Peas, when unprocessed, contain moderate levels of protein 22-25 percent but also several anti-nutritional factors (ANF); however, the levels of ANFs in peas are low compared with other legumes and peas did not induce enteritis in the distal intestine in Atlantic salmon as seen when feeding soybean meal. New feed processing technologies have provided more suitable products for use in high protein aquafeeds.

Pea protein concentrate (PPC) is produced by fine grinding dehulled peas into pea flour, followed by air processing which separates the particles based on differences in size and density. The resulting concentrate has higher protein and lower carbohydrate and ANF contents compared with unprocessed peas, and thus would be a promising protein source in aquaculture feeds.

The following study examined the efficacy and nutritional properties of pea seed protein concentrate as an alternative feed ingredient and protein source for all-male tilapia (Oreochromis niloticus) culture incorporating growth and digestibility trials.
