深海抗风浪网箱与传统网箱养殖大黄鱼数量性状差异的研究

The Difference Analysis of the the Cultured Pseudosciaena crocea Richardson Quantitative Characteristics Between in the Current-resistence Submerged Cages and the Traditional Cages

研究了深海抗风浪网箱与传统网箱养殖大黄鱼数量性状差异数量,结果表明:头长/体长、尾柄高/尾柄长、体高/体长两者之比值差异都极为显著。而鳃耙数、背鳍鳍条数t检验结果差异不显著。由此反映了深海抗风浪网箱养出来的大黄鱼头大、尾柄细、体形较传统网箱养殖大黄鱼瘦长。

In this paper, the quantitative characteristic difference of the cultured Pseudosciaena crocea Richardson in the current-resistence submerged cages and the tradional cages were studied.The results showed that there are big significant difference in HL/BL,CPD/CPL,BD/BL,but little in the number of gill and the ray of the dorsal. It can be seen that the Large Yellow Croakers Pseudosciaena crocea Richardson cultured in the current-resistence submerged cages have big heads , fine candal peduncles and good body shapes.
