花尾胡椒鲷为底层鱼类,以觅食底栖动物为主;早期幼鱼经盐度淡化驯养,能适应低盐度咸水池塘饲养。均全长3.5cm。重0.63g的幼鱼经74d池塘中间培育,长成均全长10.99cm、重27.32g,成活率87.5％。全长日均增长率1.55％,与养殖天数的关系式为L=3.6502e~(0150d);体重日均增重0.37g,日均增长率5.09％,与养殖天数的关系式为W=0.7603e~(0.0504d);全长与体重的回归方程为W=9.4642×10~3L~(3.3566),是沿海咸、海水池塘新的底层优良混养鱼类。
Flower-tip pepper sea bream as the bottom of the fish to feed predatory animals; early juvenile saltwater desalination domestication, to adapt to low salinity saline ponds feeding. Are full-length 3.5cm. The juveniles weighing 0.63g were cultivated in the middle of the 74d pond. The average length of the juveniles was 10.99cm and the weight was 27.32g. The survival rate was 87.5%. The average daily growth rate of full length was 1.55%, which was related to the number of days of cultivation as L = 3.6502e ~ (0150d). The daily weight gain was 0.37g, the average daily growth rate was 5.09% e ~ (0.0504d). The regression equation of total length and body weight was W = 9.4642 × 10 ~ 3L ~ (3.3566), which was a good new mixed culture fish in the coastal salty and seawater ponds.
