Warty Crab (Eriphia verrucosa) in the Black Sea: Biochemical Composition in the Post-reproductive Period

This study explores variations in the biochemical composition of female and male warty crabs, Eriphia verrucosa, after the reproductive period in the Black Sea. Specimens were collected from fishermen at the conclusion of the breeding season (late July) for analysis. Biochemical analysis revealed significant differences between females and males. Females exhibited higher average moisture (77.89%), slightly lower crude protein (20.96%), similar crude lipid (0.91%), and slightly higher crude ash (2.66%) compared to males (moisture: 76.30%, protein: 21.44%, lipid: 0.79%, ash: 2.47%). The study highlighted significant differences in crude protein and lipid values (p < 0.05) between sexes, with females showing lower protein content. This suggests a metabolic shift post-reproduction, where females decrease protein and potentially increase lipid content, possibly to support energy demands during ovulation. These findings offer insights into the physiological adaptations of E. verrucosa in response to their reproductive cycle, enhancing understanding of their metabolic strategies in the post-reproductive period."
