Abstract

Aim of this study is to determine the length-weight relationships of
streaked gurnard, Trigloporus lastoviza, caught
from northeastern Mediterranean. T.
lastoviza specimens were captured by commercial bottom trawler at depth of
155 to 212m off the Iskenderun Bay, Turkey. A total of 84 specimens (52 females
and 32 males) were collected. Minimum-maximum length and weight of them were
determined as 10.5-26.1cm and 5.92-163.8g for females and 6.41-22.0cm and
4.91-92.96g for males respectively. Length-weight relationships of T. lastoviza were found as W=0.0055*L^3.104,
R²=0.793, SEb=0.175 for all individuals, W=0.0076*L^2.972,
R²=0.84, SEb=0.258 for females and W=0.0076*L^2.972, R²=0.75,
SEb=0.245 for males. The type of growth for all inviduals, females and males
were isometric growth (b=3).
