The fish breeding technology has been developed very fast in last few decades and new technologies and knowledges in aquaculture industry have been bringing new problems to solve (e.g. selective breeding programs, fish welfare, best offspring needs, candidate species, etc.). In addition, there are breeding difficulties in some fish species (e.g.: Bluefin tuna, ell, grouper, etc.), therefore many institutions and companies have been giving effort to put in practice to produce these candidate aquaculture species. Two fish propagation methods were developed by the partner institute (Hungarian University of Agriculture and Life Sciences, formerly known Szent István University) researchers. These methods which will be studied in this project opens new doors to cope with many of these problems which have been faced by aquaculture industry and related scientific researches nowadays. Sperm injection, the one of the developed methods, had already been studied on some easy cultured freshwater species Cyprinus carpio and Clarias gariepinus (TRL 4) and one of the main Mediterranean cultured fish species, Dicentrarchus labrax, (TRL 3). The second method, ovarian hormone lavage, was studied on Clarias gariepinus (TRL 3) and will be first time studied on marine fish species (TRL1). The preliminary results of two methods which were not optimized yet, have been promising a new perspective for fish culture future, consortium assumes. By this project, the consortium believes in to carry Technology Readiness Levels to TRL7.
