Abstract: (5011 Views)
This experiment was performed to determine the suitable quantity of highly unsaturated fatty acids (HUFA) for survival and growth of female broodstock of White leg shrimp (Litopenaeus vannamei) during a 2- months culture period (from Apr 3 to Jun 4, 2008). Brood feed was similar in all treatmints containing and Isonitrogeneous (31.5 % protein): but the only difference between dry diets of the test was varying levels of HUFA (1, 2 and 3%). This research tested the effect of dietary HUFA on the survival ratio (SVR) and the body weight (%WG) and body length (% L), compared to those fed on fresh meals (Prenereis worm, melalis and cuttlefish). The survival ratio didn’t differ significantly between all diets (P>0.05). The (% L) in control diet was significantly higher than other treatments (P<0.05) and then1% HUFA diet was significantly higher. The (%WG) in 1% HUFA diet was significantly higher comared to other treatments (P<0.05).
