Abstract
The growth hormone (GH) secretion in cyprinids and other teleost species is
apparently regulated by several neuroendocrine factors working together. Somatostatin
is the primary inhibitor of basal and stimulated GH release while the other inhibitors
are norepinephrine and serotonin. The GH secretion is stimulated by GH- releasing
hormone, gonadotropin-releasing hormone, thyrotropin-releasing hormone,
cholecystokinin, bombesin, neuropeptide Y, dopamine and galanin. The growth rate
of cultured fish may be stimulated by neuroendocrine factors added to food, or by
administration of GH or recombinant GH preparations. Techniques for enhancing
growth rates of cultured fish are in an experimental stage.
