海马是海水水族箱中受欢迎的观赏鱼，颜色更鲜艳的个体价格更高。我们研究了基质颜色、光照强度和水温对直立海马幼鱼的存活和体色变化的影响。在为期6周的研究中，在混合颜色（绿色和橙色、绿色和红色）基质中养殖的幼鱼比在单一颜色基质（绿色、橙色、红色或黑色）中养殖的幼鱼具有更高的存活率和变色率（F - 5,F - (18) = 2.764，F - 5,F - 18 = 56.225，P < 0.05）。幼鱼的变色率随着光照强度（500、1000、1500、2000、2500和3000勒克斯）的增加而增加，在500勒克斯光照下养殖的幼鱼存活率最高（85.35 ± 5.18%）。在不同基质颜色处理中，开始变色的幼鱼的湿重、标准体长和日龄范围从产后17.26 ± 2.23天、湿重0.054 ± 0.007克、体长3.12 ± 0.31厘米（绿色和橙色混合基质）到产后25.66 ± 6.21天、湿重0.082 ± 0.013克、体长3.68 ± 0.59厘米（黑色基质）；在不同光照强度处理中，从产后14.57 ± 2.35天、湿重0.043 ± 0.009克、体长3.09 ± 0.62厘米（3000勒克斯）到产后18.41 ± 3.73天、湿重0.067 ± 0.008克、体长3.87 ± 0.49厘米（500勒克斯）。在三种温度（23℃、26℃和29℃）下养殖的幼鱼在5周后的存活率和变色率差异显著（F - 2,F - 9 = 11.053，P

Seahorses are popular ornamental fish for marine aquaria, with more colorful individuals commanding higher prices. We investigated the effects of substrate color, light intensity and water temperature on the survival and skin color change of the juvenile seahorse, Hippocampus erectus. During the 6-week study, the juveniles cultured with substrates of mixed colors (green and orange, green and red) had higher survival and color change rates than those with a single color substrate (green, orange, red, or black, F-5,F- (18) = 2.764, F-5,F- 18 = 56.225, P < 0.05). Color change rate of the juveniles increased with increasing light intensity (500, 1000, 1500, 2000, 2500 and 3000 lx) with juveniles cultured at 500 lx had the highest survival rate (85.35 +/- 5.18%). The wet weight, standard body length and age of the juveniles that began to change their skin color ranged from 0.054 +/- 0.007 g, 3.12 +/- 0.31 cm and 17.26 +/- 2.23 days post partum (green and orange substrate mixture) to 0.082 +/- 0.013 g, 3.68 +/- 0.59 cm and 25.66 +/- 6.21 days post partum (black) among the substrate color treatments; and from 0.043 +/- 0.009 g, 3.09 +/- 0.62 cm, and 14.57 +/- 2.35 days post partum (3000 lx) to 0.067 +/- 0.008 g. 3.87 +/- 0.49 cm, and 18.41 +/- 3.73 days post partum (500 x) among the light intensity treatments. Survival rate and color change rate of the juveniles cultured at three temperatures (23 degrees C, 26 degrees C. and 29 degrees C) differed significantly after 5 weeks (F-2,F- 9 = 11.053, P
