In Striostrea prismatica, along the southern coast of Ecuador, for example, gametogenesis is associated with thermal cycles (surface seawater temperature) and GI values peak in the warmer summer months (January-February) (Loor & Sonnenholzner 2014).
In Florida, gametogenesis and spawning were shown to occur during the spring-summer and late summer, respectively (Engstrom, 1980; Mosher, 1982).
This pattern of expression, higher in male gonads than in female gonads, could be due to the need for steroidogenic hormones in males during gametogenesis for which the cyp17a1 gene is responsible.
Organised by the Ministry of Interior, the First World Congress in Artificial Gametogenesis brought together some of the foremost researchers on the subject to present their findings on the viability of using such treatment in the future.
Effects of inbreeding on growth, gametogenesis, gonad production, quality and MYP expression in the sea urchin Strongylocentrotus intermedius.
sellowiana male and female gametogenesis has not been investigated previously.
Further, the MYP of sea urchins persists throughout development, a result inconsistent with its presumed role in nutrition for gametogenesis or development.
The distinction between sexes is only possible during the period of gametogenesis. Indeed, the differentiation between sexes is based on the color of the gonads.
A conditioning technique used in laboratory is to increase the temperature gradually to stimulate gametogenesis. This treatment activates the process responsible for extending the period of gamete production (Muranaka and Lannan, 1984).
Therefore, detailed information on the timing of gametogenesis is needed as a baseline for better understanding of coral spawning pattern as well as its reproductive strategy and implication on its sustainability in a region.
