Progress in longfin yellowtail and white trevally farming

The Aquaculture Research Group, composed of scientists from the Canarian Marine Science Institute (ICCM) and the University of Las Palmas de Gran Canaria (ULPGC) has made significant progress in the semi-industrial production of fast growing species in the Canaries.
In the case of the longfin yellowtail and greater amberjack (S. rivoliana and S. dumerilli) and the white trevally (Pseudocaranx dentex), the team has already been able to transfer them to offshore cages for fattening.
These tasks are carried out in collaboration with the company Canexmar SL.
The progress achieved so far will be presented at the International Congress AQUA 2012 'Global Aquaculture-Securing Our Future', which will be held in Prague from 1 to 5 September.
For some years the Canary Islands has had a firm commitment to promoting fast growing species farming, such as the longfin yellowtail and the white trevally to diversify the local fishing industry.
Under the project Improvement of larval rearing techniques of (Seriola rivoliana): Determination of essential fatty acid requirements in larval stage and food sequence optimization (METCSER), significant progress in improving aspects related to larval husbandry was achieved.
Fundamentally, progress was made in nutritional value, which limits the survival of longfin yellowtail larvae.
This project is funded through the projects call for 2011 Scientific-Technological Research of the Canary Islands Administration, reported ULPGC.
The analysis of the work done in the first annual period (2011) indicates that longfin yellowtail has the ability to gain weight, reaching 2 kg in 14 months, using only commercial feed.
It is hoped that these findings contribute to determining the potential for fattening of both species under industrial conditions and to making the first market studies.
