Abstract: (10548 Views)
With regard to the importance of polychaete Perinereis nuntia in diet of shrimp broodstock, achieving its breeding and culture bio technique is an important goal in shrimp industry. For this purpose, usage of diets inducing the highest growth and the lowest mortality is of importance. The effect of four different dietary treatments including commercial shrimp diet- Biomar, Lansy shrimp diet containing Spirulina micro algae, Enteromorpha green algae and Ulva green algae on growth and survival of this species was examined at 35 ppt salinity in present study. A number of 480 Polychaetes with average initial weight of 0.01 ± 0.002 g in four treatments and three replicates were fed the diets for three months. The results indicated significant effect of diet on final weight and survival of Polychaete. Treatments fed with commercial shrimp diet and diet containing Spirulina had higher final weight than treatments fed with Enteromorpha and Ulva algae (P<0.05). Treatments fed with Enteromorpha and Ulva algae had higher survival rates than other treatments (P<0.05). Regarding the high survival rate of treatments fed with Enteromorpha green algae and Ulva green algae and the very low weight gain difference of these two treatments with treatments fed with commercial shrimp diet and diet containing Spirulina, it is recommended to use Enteromorpha and Ulva green algae in raring Perinereis nuntia polychaete.
