Aquaculture and diseases

The production of fish and shellfish via aquaculture continues to grow worldwide. This growth makes aquaculture increasingly vulnerable to infectious diseases that can cause serious illness, mortality, and economic losses. With our bioveterinary research, we contribute to sustainable and healthy aquaculture by providing accredited diagnostics, expert consultancy, and applied research on aquatic animal diseases. 

Our specialised fish and shellfish disease laboratory in Lelystad was established in 1985. This laboratory has extensive experience with diseases affecting cultured fish intended for human consumption, as well as ornamental and wild fish, crustaceans, and shellfish. We offer rapid, accredited diagnostic testing to identify outbreaks early and provide scientific support for prevention and control.

The aquatic laboratory serves as the Dutch National Reference Laboratory (NRL) for fish and shellfish diseases, as designated by the EU. It was the first fish disease laboratory in Europe to be accredited for ISO 9001 and ISO 17025 (EN 45001) quality standards. 

As the National Reference Laboratory we:
•    Diagnose diseases in the aquaculture, ornamental fish, and wild fish industries.
•    Support outbreak investigations in cooperation with the Dutch Food and Consumer Product Safety Authority (NVWA).
•    Perform export certification diagnostics for live fish in collaboration with the NVWA.
•    Act as a knowledge and advisory center for the Ministry of Agriculture, Nature and Food Quality (LNV).
•    Conduct applied research on fish and shellfish diseases present in the Netherlands, specializing in eel and carp diseases.

Our scientists develop molecular detection methods for key pathogens, including the Koi herpes virus (KHV), the eel herpes virus (EHV), the oyster parasite Bonamia, and the shellfish bacterium Nocardia. Our research projects include studies on the eel swim bladder parasite (Anguillicola crassus), common eel parasites, and bacterial and viral infections in eel populations. 

Through our extensive national and international network, we partner with universities, research institutes, and government organizations to exchange knowledge and materials. This collaboration contributes to improved aquatic animal health, safer trade, and a more resilient ecosystem.

A healthy aquaculture industry requires strong collaboration between scientists, government officials, and industry leaders. Our aquatic experts invite partners to collaborate on improving the detection, prevention, and control of fish and shellfish diseases. We welcome collaboration on diagnostic innovations, health monitoring, and applied research projects that promote sustainable aquaculture and biosecurity.
