Inhibiting hormone gonadotrophin (GnIH) and their use for controlling puberty, reproduction, intake and growth in fish

Inhibiting hormone gonadotrophin (GnIH) and their use for controlling puberty, reproduction, intake and growth in fish. # The bass, Dicentrarchus labrax, is one of the most cultivated species in the EU. Cultivation problem is the advancement of puberty, leading to poor growth and deteriorating quality of meat. The present invention is in the field of Biotechnology (Aquaculture sector application). The invention relates to the cloning strategy inhibiting hormone gonadotrophin (GnIH) bass, containing two new peptides of the RFamida family. These peptides were synthesized and used to generate specific antibodies and have demonstrated inhibitory effects on different neuroendocrine and endocrine factors that control reproduction of seabass. This invention can be of interest to control puberty, reproduction, intake and growth of fish.
