研究了闽——粤东族大黄鱼象山港养殖群数量与质量性状,结果认为:象山港养殖大黄鱼第Ⅱ背鳍软鳍条数、鳃耙数可数性状比自然大黄鱼在数目上减少。性状指标头长/眼径,尾柄长/尾柄高,体长/体高等5项可量性状在均值上减少。而体长/头长,头长/吻长两项可量性状指标在均值上呈上升趋势。象山港养殖大黄鱼的脂肪含量远比自然产大黄鱼高(6.4倍),而鱼体中的各氨基酸含量及总量前者比后者低。
The population and quality traits of the large yellow croaker Xiangshan Harbor in Fujian-Yuedong were studied. The results showed that the number of soft-fin II dorsal fin of cultured yellow croaker in Xiangshan Harbor was smaller than that of natural large yellow croaker. Traits index head length / eye diameter, caudal peduncle length / caudal peduncle height, body length / body height five measurable traits decreased in the mean. The body length / head length, head length / length two indicators of measurable amount of the average upward trend. Xiangshan Port farmed large yellow croaker fat than natural large yellow croaker (6.4 times), and the fish in the amino acid content and total amount of the former than the latter.
