Ho Chí Minh ABSTRACT Tiger shrimp P. monodon and marine fishes are common fish cultured in coastal area of Vietnam. The study on nutrition for such species has not much when compared to freshwater fish species. Trash fish is the traditional feed for marine cultured fish and tiger shrimp in semi-intensive system. The supply is not stable in term of quality and quantity. Moreover the price has increased. Therefore finding alternative feed for trash fish is very important and crucial issues Using pellet feed in which fishmeal was replaced by plant protein that started in 90 s decade. Vietnam has 23 feed mill to produce pellet feed for shrimp. The annual production was estimated 200 000-250 000 tons. The feed mill capacity can meet the demand but Vietnam still annually imported a small amount of pellet feed at 2-5 . Using pellet for marine fish has not been common even thought there are successful trials of using pellet feed for cobia seabass in Vietnam.
