The decrease of fish captures and the increasing demand of aquatic
products for human consumption have boosted aquaculture to convert it
in an important agronomic activity around the world. One of the bottlenecks
that limit the development of this industry is the time required for most of the
cultured fish species to reach the commercial size. The regulatory system
controlling fish growth is now much better understood and we should take
advantage of this knowledge to apply it to fish culture production. Recent
advances on the role of growth hormone (GH) and the insulin-like growth
factors (IGFs) axis, and its relationship with anabolic and proteolytic systems,
involved in remodelling of fish muscle, will be reviewed in different in vivo as
well as in vitro models that aim to optimize growth and flesh quality. First,
the possibility to increase growth in terms of biological limitation has been
studied with GH prolonged treatments. The search for adequate components
or potential additives to the diet that can determine a better GH/IGF axis status
will be summarized. Finally, the physical activity of the fish during the culture
can increase growth and model the muscle structure improving flesh texture.
The regulatory mechanisms for such processes have been investigated in
different species and will be also presented. All these approaches combined
with other technical improvements can result in a significant increase of fish
production and quality, necessary to satisfy the society demand for healthy
aquatic products.
