Length-Weight Relationships Of Six Fish Species From Mangroves Of Qinzhou Harbor, Southern China

The length-weight relationships (LWRs) for six species were estimated. Fish were captured in the mangroves of Qinzhou Harbour, China, but also some specimens were purchased from fishermen. The sampling was undertaken monthly between May 2011 and April 2012 using seines (mesh size 5-10 mm; height 4 m; length 400 m) and traps (mesh size 8.5 mm; 35 cm(2) x 10 m for one unit) at seven sampling sites. Standard length was measured (precision 0.1 cm) and weight determined (precision 0.01 g) after preservation in formaldehyde (10%). Besides the equation parametersa(intercept) andb(slope) we determined also the 95% confidence limits for both parameters as well as the coefficient of correlation.
