Sistemul integrat al acvaculturii în România

Abstract

The formation of the Bicaz man-made reservoir since 1960, with a volume of 1.2 billion cubic meters, 3000 ha, 90 m depth, also generated the problem of fish exploitation, complementary to the hydropower one. The ecological diagnosis of the lake, determined during 4 decades by the researchers of the “Stejaru” Research Station and later of the Potoci Biological Station belonging to the “Al.I.Cuza Iasi” University, showed a low fish productivity in natural trophic chain specific to the oligotrophic type lakes: 2 kg trout production per ha/year, has directed our research towards the application of the integrated aquaculture system, similar to the World trend as a result of the fishing cap in the seas and oceans, at about 100 million tons/year. The biotechnology for the growth of trout in floating cages in mountain lakes, with a productivity of 100 tons/ha/year has been developed and applied since 1986. In order to determine the trout behavior in captivity, the LS-1 Bathyscaphe was invented and put into operation. The specialization and patenting of aquaculture aquaculture was carried out in collaboration with the team of Commander Jaques Yves Couteau and Aqualog Canada. Currently, over 300 tons of trout/year are produced by aquaculture on Bicaz Lake.
