Abstract
Using of alternative plant/animal based (except fish meal) raw materials is one of the most important application for decreasing feed cost in finfish feeds.
Meagre which is demanded from many countries because of its efficient meat quality and flovur and showed rapid growth under culture conditions is a potential
species. A nutrition trial with meagre, Argyrosomus regius was undertaken to evaluate the effect of replacing dietary fishmeal (FM) protein with pea protein
concentrate (PPC). A diet with FM as the main protein source was used for the control diet (FM). Four experimental diets were formulated to progressively replace
15% (PPC15), 30% (PPC30), 45% (PPC45) and 60% (PPC60) of FM protein. The study was carried out in 450-L fiberglass tanks connected to a closed recirculation
system. Eighteen fish per tank were randomly distributed into 15 tanks with three replicates. The diets were tested in triplicate for 12 weeks. The specific growth
rate (SGR) of fish fed diet PPC15 were not significantly different compared to fish fed the FM diet (P>0.05). Meagre fed FM, PPC15 and PPC30 had significantly
lower FCR compared with fish fed PPC45 and PPC60 (P<0.05). Total ammonia-nitrogen (TAN) excretion increased with elevated dietary PPC inclusion. In
conclusion, using 15% of pea protein concentrate in meagre feeds has been recommended.
