This study investigates the relationship between the total length and
body weight of the blackmouth catshark Galeus melastomus
Rafinesque, 1810 sampled along the Mediterranean coast of Türkiye
within the boundaries of the Geographical Sub-Area 24 during August
and September 2023. A total of 336 individuals, 106 females and 230
males, were caught using bottom trawl. The total length and body
weight of females range from 17.6 to 54.2 cm and 15.5 to 630 g,
respectively. For males, the range is from 16.1 to 50.7 cm in length and
from 13.0 to 426 g in weight. When considering both sexes together,
the range is from 16.1 to 54.2 cm in length and from 13.0 to 630 g in
weight. The average weight of males was calculated to be 169.43 ±
7.21 g with a standard error, while the average length of males was
36.96 ± 0.64 cm. Similarly, the average weight of females was 145.34
± 15.67 g, and the average length of females was 32.32 ± 1.06 cm. The
average length of all individuals without sex separation is 35.5 ± 0.56
cm, and the average weight is 161.83 ± 6.99 g. The length-weight
relationship is determined as W = 0.002×L3.13 (r2 = 0.97) for females,
W = 0.003×L2.94 (r2 = 0.98) for males, and W = 0.003×L3.00 (r2 =
0.98) for all individuals. The results obtained from this study are
expected to contribute to filling the knowledge gap by highlighting the
relationship between the length and weight of the blackmouth catshark
in the examined area. It will also enable comparisons with other deepsea locations in the Mediterranean Sea on this particular species.
