Length-weight and length-length relationships of Red Scorpionfish (Scorpaena scrofa L. 1758) from Aegean Sea (Turkey)

Abstract

In this study, the length-weight and length-length relationships were investigated for S. scrofa from İzmir Bay, Aegean Sea. All fish sample lengths and weights were recorded to the nearest 0.01 cm and to 0.01 g. The measured total length values for females, males and combined sexes were 16-30.2 cm; 17.7-28 cm and 16-30.2 cm respectively. The weight values for females, males and combined sexes were 73.20-441 g; 89.80-378 g and 73.20-441 g respectively. According to t test results, there were no statistically significant differences for S. scrofa species (P˃0.05); therefore, female and male samples were evaluated together. The length-weight relationship equations as y=0.016x2.993(r²=0.914) for all specimens. The ‘b’ value of LWR was not significantly different from 3.0 and their growth type was isometric. Total length-standard length relationship equations were determined as y=1.287x+0.112 (r²=0.97). This study is helpful in providing information about length-weight and length-length relationships and the current study can be useful to compare stocks of the species in the different habitats.
