The proposal in the House of Representatives by Congressman Alejandro Santana (RN ), requesting the Undersecretary of Fisheries "to bring a specific policy allowing negative control overpopulation of seals is causing capture fisheries" has not gone unnoticed, sparking protests from environmental groups and the delivery of NGOs related to the sea .
But there is overcrowding of these mammals in Chiloé?, According to Southern University's academic of Chile, Dr. Hector Pavés, "the wolf population has remained constant at around 30 000 individuals in the Lakes Region during the past ten years. Now, with data delivered in 2007 and the urgency to upgrade, there would be overpopulation. There would be fewer fish stocks, but that has more to do with management or other factors, rather than the presence of marine mammals. "
In fact, these records were raised at the workshop convened on 20 August by the SEREMI of Economics, the academic sector mitigation proposals submitted interaction sea \u200b\u200blions with artisanal or strategies of deterrence through acoustic systems in order to frighten the wolves, over the control of the population. Other experiences
control wolf population to favor fishing is not new. "Almost a century ago to do this every so often for political purposes and have no results. The extent of killing sea lions is ineffective and does not solve any of the problems of interaction between seals and fishing, only creates destruction of biodiversity and marine ecosystems, where wolves play a key role in maintaining the balance, "report Ecoceanos Executive Director, Juan Carlos Cardenas, citing the cases of Canada and Namibia, where the killing of wolves has been counterproductive. Thesis that supports the academic UACh: "I never desired results have been achieved by the removal of a predator into a system. The impact of the wolf in the total food web is unknown and we know that if at any time the predator is moved, will other birds, mammals and sharks, which will remain with available resources.
In fact, in Africa, the sector where there was interaction with fishermen mammals, we decided to remove the wolf populations. As a result, fishing was the first year, but the next one, because not really know what was the role of seals in the trophic structure. "
