Project description

Project financed by  Program 4 (Partnership) from National Research, Development and Innovation Plan II, Project value 2.000.000 RON

There are many ways to increase fish production, but only a few of them can be implemented with minimal investments and high and quick impact. Biotechnologies are applied more often in aquaculture to an increasing range of species. For now, it is a trend in the European countries to diversify the fish species reared in intensive and super-intensive systems. One of these species is the pikeperch (Sander lucioperca). Some methods to ensure fish farms with larvae, fingerlings and juveniles must be developed, in order to support setting up and development of pikeperch farms. Pikeperch fingerling and juveniles is season-linked and depends on the pikeperch’s spawning in the natural waters or in ponds kept in the period of gonadal maturation. To raise the profit of the farms, some biotechnological techniques can be applied to the pikeperch, such as out-of-season spawning and obtaining female monosex populations, successfully applied until now to some other species (trout, carp). These techniques will led to the extension of spawning period and the increase of productivity, because only females will be reared, knowing that at this species they have a better growing rate than males, thus ensuring a safe and sustainable fish production. The possibility to supply eggs, larvae and fingerlings for the farms is ensured by the out of season spawning, creating thus the premises to obtain a large number of progenies, leading in time to the development of intensive and super-intensive pikeperch rearing farms, protecting in the same time the pikeperch from the natural basins. In this project we aim to develop a technology for intensive female pikeperch juveniles production, by using some biotechnological techniques such as the out-of-season spawning.
