|Abstract:||This study evaluated reproductive performance of non-ablated Litopenaeus vannamei and the quality of their offspring under commercial conditions. Five tanks were stocked with non-ablated female and other five with ablated individuals as control. Two different larval rearing trials (Larviculture I and II) have been conducted. Six larviculture tanks (n = 3) were used on the first trial (LI) and ten for the second one (LII) (n = 3). Postlarvae from LII were used for nursery and grow-out. Spawning event and hatching rate per day were similar between both treatments. Mating success, mortality of female and number of eggs and nauplii per tank per day of non-ablated group were significantly lower than ablated female. Non-ablated female fecundity (number of eggs and nauplii per spawned female per day) was significantly higher than control. There was no significant difference between daily larval stage index of larvae in LI and LII. The response to the salinity stress test, and final survival and weight in LI was similar. However in LII, postlarvae derived from non-ablated had significantly higher survival to salinity stress test. Identical survival, final weight, weekly growth, feed conversion rate and yield were observed in nursery. The same was observed in grow-out, including weight gain and specific growth rate. Overall this study demonstrates that non-ablated females can have comparable level of productivity to ablated females in intensive commercial hatchery conditions. Their offspring perform comparably in all culture stages with evidence of enhanced resistance to stress in larvae derived from non-ablated female broodstock.|
