The TNA project PIKEPERCHSPERM has been progressing in NAIK (Nemzeti Agrárkutatási és Innovációs Központ), Hungary, over the past few months. Entitled “Different application strategies of salmon gonadoliberin analogue (sGnRHa) to improve sperm quality in outdoor pond system reared pikeperch (Sander lucioperca)”, the project is being performed at the NAIK-SDC installation. Project leader Dr Mustafa Erkan Özgür (Malatya Turgut Özal University, Turkey) and Dr Selim Erdoğan (İnönü University, Turkey) are working with NAIK staff to evaluate pikeperch sperm quality obtained off-seasonally, six months prior to the natural spawning season. This might be the earliest report of pikeperch spermiation in outdoor reared broodstock, and results could provide new insights into pikeperch reproductive biology.

The AQUAEXCEL2020 TNA programme enables external teams to access project partners’ facilities via submission of research proposals, which are funded based on an independent evaluation. Access is offered to 39 research infrastructures of participating institutes, with experimental costs, travel and subsistence covered by AQUAEXCEL2020. Available facilities cover the entire range of production systems, environments, scales, fish species and fields of expertise. Access is available to EU and Associated States’ research teams, industry, and small and medium-sized enterprises (SMEs), based on the scientific excellence of proposals and relevance to the aquaculture sector.
