Development of an induced spawning technology and hatchery manual for the eurasian perch (perca fluviatilis)

The objective of percahatch project proposal is the development of an induced spawning technology for the eurasian perch (perca fluviatilis) and subsequently compilation of a hatchery manual for this fish species. Perch is one of the emerging species in european aquaculture with a high market deman

The objective of the project is the development of an induced spawning technology for the Eurasian perch (Perca fluviatilis), a fish species native to Europe and Asia that has a good market potential and increasing interest for aquaculture. The European Union is not self-sustaining in the market of aquaculture products – in fact, 54% of consumed aquaculture products comes from import. The EU aims to reduce this dependency and to increase the sustainable production of European aquaculture. The development of a more competitive and environmentally friendly aquaculture industry is a major focus of European funding, both through European Fisheries Policy and under EU R&D programmes. Therefore one of the broad lines of activities of the Horizon 2020 is unlocking the potential of aquatic living resources. The Eurasian perch is an emerging species in European aquaculture with a current annual production of around 50 tons within the European Union. The species is characterised by excellent boneless meat and individual market size of 160-200 g that is served to the customers in the form of fillets. In intensive aquaculture systems this size can be reached within 13 months with minimal losses. The full potential of intensive perch culture, however, is not utilised due to the lack of information on various details of culture conditions. The aim of our project is to get more information and details in order to remove the abovementioned barrier in the spawning. One of the technological details to which more attention should be paid is induced spawning. Currently most farms culturing perch obtain larvae from natural spawning of the broodstock. However, for the development of efficient intensive culture induced spawning is vital for the production of good quality fry. This allows the synchronisation of sexes, precise timing of ovulation and better scheduling of the entire production system. Induced spawning includes technological steps such as the preparation of spawners using a light and temperature regime, hormonal stimulation of ovulation and spermiation, stripping and fertilisation of gametes and incubation of fertilised eggs until hatching. In case of the Eurasian perch several details of induced spawning have been developed and described in detail, however, these have not been compiled into a single working technology that can be described and marketed as a product. In the current project we are planning to test the available information and knowledge in farm conditions and develop and induced spawning technology by describing the technological steps in detail. The developed technology will allow farmers to maximise the security of larval production for successful perch farming. The project result will contribute to strengthen the European farms in the global competition and increase the perch production in the EU, drawing attention on high standards and consumer protection. Furthermore it could implement one of the main focuses of the aquaculture strategy, namely the realisation of full potential of the aquaculture sector. Since the consortium leader is an SME the results of the project will be utilised in the market.
