Over the years knowledge of fish breeding requirements has improved and the ability developed to induce breeding artificially, through the use of natural or synthetic hormones and/or environmental manipulations.
Biotechnology is the use of biological systems or living organisms in production processes and this has found a wide range of useful applications in fisheries and aquaculture. The field of genetic biotechnology ranges from simple techniques such as hybridization, to more complex processes such as the transfer of specific genes between species to create GMOs (Genetically Modified Organisms).
It brings opportunities, for instance, to increase growth rate in farmed species, boost the nutritional value of aqua feeds, improve fish health, help restore and protect environments, extend the range of aquatic species and, improve the management and conservation of wild stocks.
Biotechnology could be one of the answers to problems faced by the aquaculture industry.

I think genetic biotechnology can also be used in conserving the gene banks of species. In this era of commercialization, people tend to ignore the species affected. If we could identify the genes present in the DNA; would help in the future to restore affected populations.
On the other hand, and for production purposes, biological traits not sought today might be needed in the future, and a recovery path must be left available through which we can trace back the species of affected populations.
