Abstract

In this study, total length-weight relationships and condition factor of
shi drum (Umbrina cirrosa) were examined in the North-eastern Mediterranean Sea. Umbrina cirrosa individuals were
captured by gillnets between May 2017- April 2018 at a depth of 15 m from
Mersin Bay. A total of 218 (115 male and 103 female) U. cirrosa were collected. Minimum-maximum length and weight of
caught fishes were determined as 13.5-26.7cm and 19.12-214.04g for females and
13.8-26.8cm and 21.48-201.75g for males respectively. Total length-weight
relationships of U. cirrosa were
found as W=0.0028*TL^3.42, R²=0.989, SEb=0.024 for
combined sexes, W=0.0029*TL^3.414, R²=0.988, SEb=0.037 for
females and W=0.0028*TL^3.423, R²=0.998, SEb=0.031 for
males. 95% Confidence intervals for b value for combined sexes were 3.371-3.466.
According to b values, combined sexes, females and males showed a positive
allometric growth (t-test: p<0.05). Condition factors were 0.923±0.063 for
all specimens, 0.930±0.009 for females and 0.917±0.008.
