Estimation of some hemolymph components in the swimming blue crab Portunus segnis and the invasive crab Eriocheir hepuensis in the Shatt al-Arab and northeastern Arabian Gulf, Iraq

الملخص

Seasonal fluctuations in the concentrations of the enzymes alanine transaminase ALT and
aspartae aminotransferase AST in males of Portunus segnis reached 28.5, with the lowest values
being 12.2. The greatest concentrations of the AST enzyme were 24.3, with the lowest concentrations
being 15.3. Females had the highest ALT enzyme values of 27.9 and the lowest readings of
12.3. The highest values for AST enzyme concentrations were 17.8 and the lowest values were
8.2, and the highest values for invasive crab males Eriocheir hepuensis were 64.2 and the lowest
values were 22.2; the highest values for AST enzyme concentrations were 69 and the lowest
concentrations were 28.2, while the highest values for ALT enzyme concentrations were 62.3 and
the lowest values were 25.3. The highest AST values were 67.9, while the lowest readings were
22.4. In terms of seasonal changes in total protein, glucose, and cholesterol concentrations in
male blue crabs, the highest and lowest total protein concentrations were 7.5 and 4.7, respectively,
while the highest and lowest glucose concentrations were 2.9 and 1.2, and the highest and lowest
cholesterol concentrations were 1.9 and 0.2, respectively, while in females it reached 1.9 and
0.2. The greatest and lowest total protein concentrations were 5 and 2.6, respectively, whereas
the highest and lowest glucose concentrations were 2.3 and 1.4, and the highest and lowest
cholesterol concentrations were 0.9 and 0.3. The highest and lowest concentrations of total
protein, glucose, and cholesterol in the invasive crab males were 1.4 and 2.9, respectively, as a
result of seasonal fluctuations in total protein, glucose, and cholesterol. The highest and lowest
glucose concentrations were 9.7 and 5.9, respectively, while the highest and lowest cholesterol
readings were 1.8 and 1.0. Females had the greatest and lowest total protein concentrations of
2.7 and 1.4, respectively, whereas the highest and lowest glucose concentrations were 7.0 and 3.0,
respectively, and the highest and lowest cholesterol concentrations were 1.9 and 1.3.
