- Abstract
A 84-day feeding experiment of two juvenile horseshoe crab species, including nine formulated diets with three digestible protein ( DP) levels (36%, 40% and 44%) and three digestible energy ( DE) levels (14, 16 and 18 kJ g−1) versus the control, fed on frozen brine shrimp ( Artemia salina), was conducted. The results showed that the survival rate of Tachypleus tridentatus ranged from 67% to 100%, while that of Carcinoscorpius rotundicauda varied from 44% to 100%. The results also indicated that the formulated diet containing 40% DP with 14 kJ g−1 DE was the best, in terms of growth and feed utilization, for the two juvenile horseshoe crab species. Final body weight ( FBW), thermal-unit growth coefficient ( TGC), feed efficiency ( FE), nitrogen retention efficiency ( NRE) and energy retention efficiency ( ERE) of T. tridentatus fed 40% DP and 14 kJ g−1 DE were significantly higher than that of T. tridentatus fed the control diet. However, for C. rotundicauda, only significantly higher FE, NRE and ERE were found in juveniles fed 40% DP and 14 kJ g−1 DE than the control diet. The present findings revealed that the optimum DP/ DE ratio for the two species was 28 g protein MJ−1.
