(Elsevier, 1992)
The effect of light color (green, blue and white fluorescent lights, with natural light as a control) on maturation in intact and eyestalk-ablated Penaeus monodon was tested in 12-m<sup>3</sup> broodstock tanks. Size and ...
A comparison of the annual changes in testicular activity and serum androgen levels between the early and delayed maturing groups of male Cottus hangiongensis
(Springer Verlag, 1992)
Annual changes in testicular activity and concentration of two serum androgens were monitored in two groups of the river-sculpin Cottus hangiongensis collected from the upper and lower reaches of a river at southern Hokkaido, ...
Ovarian changes and female-specific protein levels during sexual maturation of the white shrimp Penaeus indicus
(Society of Israeli Aquaculture and Marine Biotechnology, 1992)
The histological changes in the ovary and female-specific protein levels in the hemolymph during sexual maturation of Penaeus indicus were determined. Ovarian maturation was classified into four stages: immature stage, ...
Lunar synchronization of spawning in sea bass, Lates calcarifer (Bloch): Effect of luteinizing hormone-releasing hormone analogue (LHRHa) treatment
(Wiley-Blackwell, 1992)
Based on egg collection records, spontaneous spawning activity of sea bass, Lates calcarifer (Bloch), reared in floating net cages followed a semilunar cycle. The peak of multiple spawnings coincided with declining spring ...
