| 摘 要： | A two-month study was conducted to test the e?ects of macroalgae on the growth and survivorship of
juvenile lined seahorse (Hippocampus erectus) in aquaria. Twenty-day old seahorses were cultured
in the tanks with green alga Chaetomorpha linum, red alga Gracilaria tikvahiae, green plastic
artiˉcial plant (stargrass), and black plastic net, respectively. Increases in wet mass and standard
length for the seahorses were signiˉcantly higher in the tanks with macroalgae than those without
macroalgae. The seahorse survivorships in the two macroalgal treatments were also signiˉcantly
higher than those of the two treatments without macroalgae. In the treatments with macroalgae,
the DO and pH were higher than those without marcoalgae. During the experiment, the color of
seahorses was changed to certain extent. In the green background (the treatments with C. linum and
stargrass), 24.1%{28.4% of black seahorses decreased over time; whereas in the black (plastic net) or
brown (G. tikvahiae) background treatments, 14.1%{16.3% of yellow seahorses decreased over time,
for matching that of the background. Furthermore, the survival rate of seahorse was correlation
with DO and pH, and strong correlation with standard length, wet mass and CF. Polyculture with
macroalgae, survival rates of seahorse were higher than without macroaglae.
