The study was designed to develop a reliable technique for inducing ovarian maturation and spawning in Litopenaeus stylirostris and Litopenaeus vannamei, as an alternative to the traditional and destructive eyestalk ablation. Two combinations of molecules were evaluated: (a) serotonin (5-HT) at 50 μg g -1 body weight (b.w.)+juvenile hormone (JH III) at 227 ng g -1 b.w., and...
The effect of serotonin (5-hydroxytryptamine, 5-HT) injection on the ovarian maturation and spawning of wild Penaeus vannamei was investigated. The neurotransmitter was evaluated at 15 μg g -1 body weight (b.w.) and 50 μg g -1 b.w., applied at day 1, 11 and 21. The effect was compared against a control group, which received the injection of the sterile vehicle solution (NaCl...
