Length-weight relationship, condition factor and size composition of Periophthalmus barbarus (Linneaus 1766 ) in New Calabar River, Nigeria

摘要

A study on the length-weight relationship, condition factor and size composition of Periophthalmus barbarus consisting of 1572 samples over a period of twelve months (February 2008- January 2009) in New Calabar River Nigeria revealed a length range of 4.1-14,2cm mean (8.64±1.27) and weight of 0.70-39.62g mean (11.16±7.29). The growth was negatively allometric (2.73±0.0545). The condition factor for the species was 1.190±0.047. Slight variations were observed in the condition factor of various size classes with the midclass recording the least values. The size distribution of the species had a normal curve.
