本研究确定了隶属于4科的4种鱼类,即日本鱼(Inegocia japonica)、十棘鱼(Gerres decacanthus)、亚洲鱼(Sillago asiatica)和红鱼(Evynnis cardinalis)的总长度-重量关系。采用商业拖网在钦州港采集鱼类。2017年3月至12月每季度采集一次样本。记录每个标本的总长度和总重量,精度分别为0.1cm和0.1g。在采样期间,共收集和测量了111条鱼。长重关系异速生长系数(b)的变化幅度分别为:红雀花3.08、白花3.17、亚洲西洋槐3.18、十棘草3.19。发现这四种鱼类的生长是等距的。
This study determined the total length-weight relationships of the four fish species, Inegocia japonica, Gerres decacanthus, Sillago asiatica, and Evynnis cardinalis, belonging to four families. Fishes were collected using commercial trawls from Qinzhou harbor, China. Samples were collected quarterly from March to December 2017. Total length and weight of each specimen were recorded with an accuracy of 0.1cm and 0.1g, respectively. During the sampling period, a total of 111 fish individuals were collected and measured. The allometric coefficient (b) of length-weight relationship varied from 3.08 for Evynnis cardinalis, 3.17 for Inegocia japonica, 3.18 for Sillago asiatica and 3.19 for Gerres decacanthus. Growth was found as isometric for this four fish species.
