Yellowtail kingfish and corvina drum promoted to boost aquaculture
(CHILE, 6/25/2014)
The Chilean government intends to boost the culture of species such as corvina drum (Cilus gilberti) and yellowtail kingfish (Seriola lalandi) as part of a strategic plan to develop the fisheries-aquaculture sector.
The Undersecretariat of Fisheries and Aquaculture (SUBPESCA) indicated that the intention is to promote alternative aquaculture resources to the production of salmon and also partially solve the problem of lower income in the fisheries sector due to the decline in catches, the newspaper El Mercurio informed.
The yellowtail kingfish and the corvina drum are species under research as part of a programme of the Corporation for the Promotion of Production (CORFO).
According to the fishery and aquaculture sector advisory of the entity, Sonia Barria, they have been working on this initiative for three years and they are beginning to develop farmed species-related lines.
Each resource is investigated considering different topics. In the case of the yellowtail kingfish, part of the research is the pre-fattening and fattening processes on land. This involves the development of a line of crops and cages or ponds to be able to raise fish on land, Barria explained.
Meanwhile, the company Acuícola Norte -- developer and co-financier of the study --works with a laboratory engaged in producing vaccines to combat diseases affecting the yellowtail kingfish.
From SUBPESCA it has been stressed that Acuicola Norte is already exporting juvenile specimens of yellowtail kingfish to the European Union market.
The executive director of the Centre for Development and Technology Transfer (CDTT) of Fundación Chile, Axel Klimpel, noted that this resource is fully adaptable to farming in captivity and has good production rates.
"We believe it is a species that deserves special attention and should continue to develop along with technological adaptations, since it presents an interesting diversification alternative for aquaculture diversification in northern Chile," he pointed out.
"Currently, we have the juvenile production technology completely under control," he added.
Fundación Chile is also addressing the corvina drum development research, together with CORFO.
In this regard, Klimpel explained that "the intention is to develop the whole culture technology, from juvenile production to the fattening process and adult fish harvesting."
The CDTT, located in the Bay of Tongoy, is working in corvina drum fattening in cage platforms in Region IV, Coquimbo, and has made "significant progress in reproduction of" corvina drum, "which makes it possible to have preliminary juvenile production technology."
During this study, the fish are kept in ponds on land with sea water, fed with fresh fish and food supplements, and with a daily record of the main environmental parameters.
Once the juvenile production stage is mastered, the next step is the development of technology for the corvina drum commercial production.
The head of SUBPESCA aquaculture division, José Miguel Burgos, thinks that apart from the corvina drum and the yellowtail kingfish, seaweed farming is another activity with great potential for the aquaculture sector.
"We believe that Chile has a lot of advantages over countries that are now producing these species," he stressed.
