Abstract EN
The objective of the study was to find a cost-effective feed from three commercial feeds, namely, Arasco (Saudi Arabia), Skretting (Turkey), and Biomar (Greece) for commercially producing silver black porgy (sobaity bream), Sparidentex hasta in Kuwait.
For confidentiality, these feeds were randomly given code names, diets 1, 2, and 3, which were known only to the investigating staffs.
The trash fish (diet 4) was used as the control.
The experiment was conducted for 28 wk with grow-out sobaity bream (210.0± 0.51 g) using a flow-through system consisting of twelve 1-m3 tanks.
There were three replicates for each treatment.
Fish were fed two times daily at satiation level.
The results showed that fish fed diet 2 resulted in significantly (P > 0.05) better growth performance, feed utilization, and higher fillet eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA) content compared to other diets.
A comparison of fillet quality of cultured and wild sobaity bream showed no significant (P >0.05) difference between sensory attributes, except that of ‘flavor’ in cooked fillets of wild sobaity bream.
A simple economic analysis showed that the cost per kilogram of fish production was significantly (P >0.05) the lowest in diet 2 (USD4.13), followed by diet 1 (USD5.70), diet 4 (USD6.33), and diet 3 (USD6.92).
Thus, based on growth performance, feed utilization, cost of production, and nutritional quality of fillet, it is concluded that diet 2 may be recommended for commercial culture of sobaity bream in Kuwait.
However, future research should focus on how to improve fillet quality of the cultured fish at par with wild fish by manipulating the feed formulation.
