Abstract

This study has been carried out to compare the effect of a locally manufactured shrimp feed by the national company of Arasco; to three imported commercial feeds (Rangen of USA, Marine feed of  Singapore and President of Taiwan) on two local shrimp species, the Tiger shrimp Penaeus monodon and The white shrimp P. indicus, for nursery and grow-out periods. Results revealed no significant difference (P 0.05) in survival rates, but final weight, length and production were significantly different (P< 0.05). 
Growth rates were with Rangen feed significantly higher (P< 0.05) over the rest of the feeds for  nursery and grow-out culture periods. (Marine feed) ranked second significantly (P< 0.05). President feed ranked third in comparison with Rangen and Marine feed and was better significantly 
(P< 0.05) when comparing with Arasco, in survival rates and growth with Penaeus indicus, but not with P. monodon (P> 0.05)  for both nursery and grow-out culture periods.
The (Arasco) feed was too high in cohesion of its grains to the three imported feeds.
