中文摘要

The color metamorphosis, growth performance, food intake, total harvest weight and survival rate of
a juvenile hybrid ornamental fish, blood parrotfish fish (Cichlasoma citrinellum × Cichlasoma synspilum)
was studied at three different temperature, 18oC, the temperature of natural variation (24.4-28.7oC) and
32oC for 84 days, respectively. The results showed that growth rate of blood parrotfish reared at 32oC
was significant higher than that of blood parrotfish reared fish at 18oC and natural temperature variation,
resulted from the increase of food intake accompanying a decrease of feed conversion ratio. In addition,
an adverse temperature of 18oC results in an insignificant growth and no color metamorphosis in blood
parrotfish during 84 days of culture. Results of the present study strongly suggested that better rearing
temperature of blood parrotfish is 32oC.
