Length-Weight Relationships of Four Fish Species from Qinzhou Harbor, Guangxi, China

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
