Abstract:

This study aims at investigating the variation in protein levels in the muscles of three local carnivorous fish species across three different seasons. The species studied were Leuciscus vorax, Silurus triostegus, and Coptodon zillii. The results revealed differences in muscle protein levels among these species. In autumn, the average muscle protein concentration was 19.5 ± 0.5% for L. vorax, 22.9 ± 0.5% for S. triostegus, and 16.3 ± 0.5% for C. zillii. During winter, the protein concentration was 18.9 ± 0.4% for L. vorax, 20.5 ± 0.5% for S. triostegus, and 18.9 ± 0.5% for C. zillii. In spring, the protein concentration increased to 20.4 ± 0.2% for L. vorax, 19.9 ± 0.5% for S. triostegus, and 18.8 ± 0.5% for C. zillii. The study also examined the activity of digestive enzymes such as ALP, GPT, and GOT in the flesh of these three species across the seasonal changes. This study aims at determining the optimal muscle protein levels in these carnivorous fish species, which vary with the seasons and the ecological characteristics of their habitats. This information can help assess the nutritional value of consuming the flesh of these fish.
