New Research Helps Breeding of Senegalese Sole

12 June 2012, at 1:00am

SPAIN - Researchers from the Institute of Research and Technology (IRTA) and the National Research Council (CSIC), led by Dr Joan Cerd, have succeeded in producing recombinant gonadotropins (rFSH and rLH) in Senegalese sole.

Gonadotropins are the major hormones responsible for the formation and maturation of gametes and, therefore, are key to developing methods for controlling reproduction of fish in captivity.

Senegalese sole aquaculture is currently limited by the inability to control reproduction, particularly of males bred in captivity, which show a varying semen quality and low rates of fertilisation.

Recombinant hormones that have occurred may have a significant impact on aquaculture and sole as it will enable the design of selective hormonal therapies for the induction of male sexual maturation and thus, optimise methods of in vitro fertilisation and cryopreservation of semen.

This work was funded by the Fundacin Ramn Areces and will soon be published in the international journal Biology of Reproductio.

Aquaculture is an increasingly important source of safe, nutritious, and sustainable seafood for people worldwide. Globally, aquaculture production must double by 2030 to keep pace with demand. These increases in demand for aquaculture products, food security considerations, and job creation have generated an increased need for skilled workers.
