Growth and survival rates of domesticated and non-domesticated breeding stocks of Penaeus monodon Fabricius, 1798 cultured in ponds and tanks
ISRAELI JOURNAL OF AQUACULTURE-BAMIDGEH(2022)
Abstract
Sourced breeders from domesticated broodstocks have played an essential role in the steady development of shrimp culture in many countries. In the present study, two experiments were performed in Tra Vinh province, Vietnam, to compare the culturing benefits of sourced breeding stocks from domesticated and non-domesticated Penaeus monodon broodstock. The first 90-day experiment was randomly arranged with three repetitions in six earthen ponds (1,500-2,000 m(2)). Experimental shrimp (PL12) were stocked at a density of 20 ind.m(-2). The second experiment was randomly designed with three repetitions in six composite tanks (6.0 m(3)). PL15 of experimental shrimp were cultured at a density of 30 ind. m(-2) for 120 days. Grobest pellet feed (40 % protein) was used in both experiments. At experiment termination, the mean weight (26.09 g) and length (15.68 cm) under pond culture, as well as respective values of 15.57 g, and 13.21 cm under tank culture, for D-shrimp were significantly higher than those of W-shrimp (p<0.05). Similarly, the survival rate (84.33 %), FCR (0.98), and yield (3,558 kg ha(-1)) under pond culture, as well as the survival rate (87.59 %) and yield (470 g m(-3)) under tank culture, of D-shrimp were significantly better than those of W-shrimp (p<0.05). These results prove that the grow-out culture of shrimp postlarvae from domesticated broodstocks resulted in superior performance to those from wild broodstocks.
