A group of researchers of the University of the Valley of Itajaí (Univali) is preparing to transfer sardines (Sardinella brasiliensis) raised in captivity on the northern coast of Santa Catarina to tuna vessels, where they will be used as live bait for tuna fishing.
To reach this stage, about 8,000 sardine larvae produced at the Laboratory of Marine Fish Culture (Lapmar) of the Federal University of Santa Catarina (UFSC) had been transferred to a net tank before.
The larvae are developing in a farming area in Univali located in Itapocorói, in the town of Penha.
According to Gilberto Caetano Manzoni, Univali researcher and one of the project leaders, "the success of this action crowns eight years of research in the field of live bait production."
The live bait study began in 2005, when experts of the Cepsul/ICMBio and of the Technological Science Centre of the Earth and the Sea (CTTMar/Univali) began to investigate for the first time the reproduction of sardines in captivity, Univali reported.
The project gained momentum in 2010 thanks to the contribution of resources from the High Level Staff Improved Coordination (CAPES/MEC), through the establishment of an agreement with Lapmar/UFSC.
At that moment the study and the development of the methodology for sardine reproduction in laboratory were started.
Manzoni explained that the research was born out of the need to reduce fishing pressure on the sardine natural stocks, which were undergoing biomass changes due to overfishing.
"With the ability to produce the species in captivity, the ships do not need to go to sea to find sardines to be used as bait for catching tuna, which means saving time and fuel," noted the scientist.
The sardine fishery sources two important industrial fish production lines: canned tuna and sardines.
In the first case, it provides juvenile specimens that are used as bait in fishing for tuna while, in the second case, it is fished as a target species as adult specimens.
