Aquatic animals exhibit a high degree of sexual plasticity, including genetic and environmental sex determination, sex change, and hermaphroditism. That makes aquatic animals amenable to techniques of sex control for aquaculture and basic studies of sex determination and differentiation. Sex control techniques have been applied to generate monosex stocks for higher yield in commercial aquaculture and also used to analyze the mechanism of sex differentiation. In addition to potential growth advantages, monosex stocks also have other benefits to aquaculture, such as improving body size traits and dress-out percentage, minimize ecological impact and body coloration at harvest. Monosex stocks can be obtained by two main approaches, one is the direct mean which treated aquatic animals with sex steroids or extreme temperature. An alternative strategy for monosex production is the indirect mean without hormone treatment, such as chromosome manipulation. Furthermore, sex reversal brood obtained by direct or indirect method can mate with the normal brood for producing monosex stocks.
Sex change is an important process in production of monosex stocks. During the sex change, critical pathway and genes involved in the sex differentiation are altered. Therefore, research on the genetic basis and potential mechanisms of sex differentiation is necessary for application in aquaculture and species conservation. In recent decades, remarkable progress has been obtained in sex control, sex differentiation mechanism and so on.
This Research Topic aims to provide an overview of the fundamental discoveries in the field of aquatic animal sex control and sex differentiation. We welcome submissions of different types of manuscripts including original research papers, reviews, and methods, including but not limited to:
We welcome submissions covering the following subtopics, but are not limited to:
1. Direct methodology for sex control, such as treatment using steroids, temperature, light, and/or pH value, etc.
2. Indirect methodology for sex control such as gynogenesis, induction of polyploidy, etc.
3. Mechanism of sex change of aquatic animals under various treatments.
4. The molecular mechanisms of sex differentiation
