Potamon persicum Pretzmann,1962’nin et verimi ve kimyasal bileşimi

Abstract

In this study, morphometric measurement, meat yield, moisture, pH, protein, fat, fatty acids and ash content were determined in a total of 102 (15 female and 87 male) freshwater crab (Potamon persicum Pretzmann,1962) caught from xxxxxxxx. Meat yield in male and in female crabs were found to be as 12.75±0.38% and 10.93±0.32% respectively. It has been observed that moisture and protein amounts were higher in female crabs than in male crabs. The amounts of fat were 0.96±0.31% in male crabs and 0.97±0.35% in female crabs. The ash contents were found to be as 2.68±0.04% in male crabs and as 2.66±0.03% in female crabs. It was determined that the content of monounsaturated fatty acids (female:male 33.56%:37,44%) in female and male crabs were higher than polyunsaturated (female:male 24.19%:21.62%) and saturated fatty acid (female:male 28.11%:32.85%) content. The highest fatty acid was found to be as omega-9, in terms of omega-3 (male crabs % 8.54, female crabs %14.85), omega-6 (male crabs % 10.04, female crabs %5.46) and omega-9 fatty acids (male crabs % 23.65, female crabs %19.14) in freshwater crab (Potamon persicum Pretzmann,1962) meat.
