PRODUCTION OF PENAEID SHRIMP IN EUROPE
– Risks and opportunities –
Over the past few years, the shrimp industry – in particular the RAS production of Litopenaeus vannamei – has experienced vast growth throughout Europe. While focusing on the implementation of new production methods, increased production standards and optimized system design, the European shrimp grower gave scant attention on the supply of post larvae as the import of PL`s was uncomplicated and relatively inexpensive.
Earlier last year, the major PL supplier of the European marked announced a halt in supply as of October 2018. Even though the European shrimp producers were long aware of this bottleneck and the reliance on a single importer, they failed to establish diverse supply sources.
To face this bottleneck and to find suitable approaches to these issues, the Competence Network Aquaculture, Future Ocean and the EuroShrimp Team organized a presentation series with a subsequent workshop to deal with the upcoming problems the European shrimp aquaculture has to face in the close future.
Recent research at the AWI in Bremerhaven and by Egyptian researchers at NIOF in Alexandria has shown that shrimp and tilapia are optimal for culture in the same RAS system. Growth rates indicate that tilapia biowaste/faeces can be used as a sole diet for high-value shrimp, irrespective of the feeding regime. Beyond known benefits such as higher yield and efficient resource use, our results show that co-culture of the two species is successful in terms of nutritional provision and shrimp health status.

We at AWI and the University of Auckland have been busy, with the support of the Federal Ministry of education and Research and the Royal Society of New Zealand and have released new studies on sound in aquaculture including RAS and pond shrimp farms which can be found here. We continue our studies and hope to present you with some results directly testing the impact of soundscapes on shrimp stress and immune responses very soon.
