Spanish Researchers Successfully Breed Queen Corvina Fish in Captivity27 September 2013
SPAIN - The National University (UNA) is breeding the queen corvina fish (Cynoscion albus) in captivity after its catches in the wild have declined in recent years.
The queen corvina is one of the most commercially important fish caught in the Gulf of Nicoya.
Juan Bertoglia Richards, School of Biological Sciences at UNA, is now focusing on reproducing the fish in captivity. His work is a first step towards queen corvina aquaculture in the Gulf of Nicoya.
After keeping the fish in captivity for more than two years, hormonal induction was carried out.
"After waiting for about 48 hours, both females and males released their sexual products to the water, achieving fertilization and obtaining the first captive fertilized eggs," said Jorge Boza Abarca, coordinator of the Laboratory.
"The fish are hard to get wild, because they are caught by artisanal fishermen in the Gulf of Nicoya and exposed to hours of stress by staying hooked on the hooks, and then transported by boat to the breeding tanks," said Mr Boza.
Achieving the breeding of queen corvina in captivity is the first step in the development of mariculture in the Gulf of Nicoya.
