Some Morphological Characteristics of Five Marine Fish Species of Hormozgan coastal waters (Northern Persian Gulf)
Journal Title: Caspian Journal of Applied Sciences Research - Year 2012, Vol 1, Issue 6
Abstract
Length-weight relationships, condition factors and optimum length were estimated for five fish species of Hormozgan coastal waters, namely Leiognathus bindus, Platycephalus indicus, Pseudorhombus arsius, Upeneus sulphureus and Arius thalassinus. Collection of samples was conducted on bimonthly basis from January 2010 to January 2011 using bottom trawl net from depths of 5–28m. All length-weight relationships were highly significant and the parameter b ranged between 2.584 in U. sulphureus and 3.146 in L. bindus. Relative weight (Wr) had significant differences between caught species (Kruskal-Wallis test, χ2=36.342 and P<0.001) and ranged from 59.42% (L. bindus) to 134.00% (P. indicus). Relative condition factor (Krel) also ranged from 0.98 ± 0.11 and 0.98 ± 0.17 (A. thalassinus and P. arsius, respectively) to 1.07 ± 0.35 (P. indicus). The optimum length (Lopt) were calculated for all species and ranged from 8cm in L. bindus and 68cm in A. thalassinus. Present study provides basic information for fisheries management in the Persian Gulf.
