Investigations: A baby with symmetrical gonads is most likely an under-virilised male and similarly absence of gonads and presence of uterus indicate a virilised female.
It weighed 114 g in body weight, 4.3 g in gonads, measured 70 mm TD and 38.4 mm in test height.
At the end of the experiment, the shrimp were dissected on ice, with the body and wet gonads weighed and then dried to a constant weight at 65 AdegC in an oven.
In the male fetus a fully comprehensive gender diagnosis will include the identification of: penis and prepuce, scrotum/testicular compartments, urethra and gonads. The penis is visualised in the ventro-caudal abdomen, just behind the umbilicus, may be partially/completely encased within the prepuce or appear fully extended and occasionally erect.
Gonads in an early development subphase were found in larger females, which had a mean TL of 220.5 mm (SD 39.9), a mean BW of 362.3 g (SD 150.7), a mean GW of 19.1 g (SD 9.7), and a mean GSI of 4% (SD 0.7).
Fish Biology--Particularly for female fish, a large proportion of seasonal weight fluctuations can be attributed to gains and losses in gonad weight.
After dissection, the individuals were sexed by observing the presence of lamellae on the female gonads and the relatively smooth male gonads as in Flynn and Benfey [42].
The aim of the study were to investigate the presence of heavy metal contaminants like Lead (Pb), Cadmium (Cd) and Nickel (Ni) in three commonly consumed fish, determine the concentration of bio-accumulated HMs in liver, gill, kidney, gonad and muscle of fish and find out whether the studied fish have elevated concentrations of HMs in their tissues that could render them dangerous for human consumption, by comparing with the maximum permissible limits proposed by FAO and WHO.
Indeed, they are easily recognizable by the color of the gonads: female gonads are green or brown in color, the males are pinkish cream.
Biopsy of the gonads confirmed them to be ovo-testes with predominance of testicular tissue.
