摘要: The lined seahorse, Hippocampus erectus (Perry), is an important species in both medicinal and aquarium trades. The aim of this study was to evaluate the effects of stocking density (1, 3 and 5 individuals L-1) on the growth performance and survival of the early-stage juvenile H. erectus. The height (HT), wet weight, weight gain (WG) and specific growth rate (SGR) were affected significantly by the stocking density during the 40-day study. The HT, WG and SGR of the seahorse at 1 and 3 juveniles L-1 were significantly higher than that at 5 juveniles L-1. The survival of juveniles at the three stocking densities was not significantly different at day 25 (90.3 +/- 4.5%, 86.7 +/- 4.2% and 86.2 +/- 3.8% for 1, 3 and 5 juveniles L-1 respectively), but was significantly different at day 40 (87.8 +/- 3.9%, 69.6 +/- 4.2% and 52.9 +/- 2.8% for 1, 3 and 5 juveniles L-1 respectively). For the early-stage juvenile H. erectus, we recommend a stocking density of 3 juveniles L-1, but the density should be reduced to 1-2 juveniles L-1 to avoid reduced and variable growth and high mortality after 25 days.
