The article focuses on the development of grouper culture. It notes that while volitional spawning can apparently be achieved in at least some grouper species, many more appear to undergo maturation in captivity and can be induced to spawn with hormones. Also, the transition from female to male sex in groupers is generally influenced to some degree by social circumstances but the extent to which hierarchies and size differences are involved can be very significant. Groupers generally change sex during their life-times, maturing as females and then becoming males as they grow larger and older.

The article discusses a genetic improvement in the African sharptooth catfish. In a 2005 study, Martins et al. documented significant individual growth variation among individually housed juveniles of this species. Although variation was low in terms of initial body weight and feed consumption, final body weight, specific growth rate and feed conversion ratio all exhibited high variation by the end of the growth trial. While many genetic studies require dividing individual spawns into smaller portions for incubation under varying conditions, it is not always easy to handle and manipulate these small aliquots under practical conditions. With its rapid growth, tolerance of poor environmental conditions and high fillet yield, the sharptooth catfish has tremendous potential for aquaculture in Africa and elsewhere. Genetic improvement of captive stocks will be an important aspect in the expansion of its production.

The article relates the concept of genetic correlations to the evaluation of the economic traits of fish culture. The author claims that the determination of the correlation of the traits of aquatic organisms can give fish farmers the ability to estimate phenotypic, environmental and genetic correlations between traits. He defines genetic correlations as the relationships between phenomena, characteristics or variables that are based on genetic influences. Based on the article, gene products can affect traits such as coloration, finnage or disease resistance.
