Fish Health Unit Report of Activities Undertaken in 2018 and 2019
This report summarises the activities undertaken by the Fish Health Unit (FHU) of the Marine
Institute (MI) in 2018 and 2019. The services of the FHU, undertaken on behalf of the State,
are largely driven by European and national legislation on aquatic animal health. European
Council Directive 2006/88/EC on animal health requirements for aquaculture animals lays
down rules for the control of aquatic animal health within the EU. The directive is enacted in
Irish Law by Statutory Instrument (SI) 261 of 2008. The MI is the Competent Authority (CA)
responsible for implementation of aquatic animal health regulation in Ireland as described in
these statutes.
Aquatic animal health regulations in SI 261 of 2008 apply to finfish farms, shellfish farms, and
put and take fisheries, and require that such aquaculture production businesses (APBs) obtain
a Fish Health Authorisation (FHA) from the CA prior to operation

Full text available online: http://www.int-res.com/articles/dao2008/83/d083p181.pdfpeer-reviewedViral gametocytic hypertrophy (VGH) was detected during an investigation of mortalities in Pacific oysters Crassostrea gigas from 2 separate Irish production sites. The basophilic inclusions were observed in the gonad tissue of oysters sampled in August and October 2007. The oysters involved did not show any macroscopic disease signs. Transmission electron microscopy demonstrated the presence of viral particles in these intranuclear inclusions. The particles were small, non-enveloped, icosahedral and approximately 50 nm in diameter and thus had characteristics similar to the Papillomaviridae and Polyomaviridae families. No host defence reaction was observed. The viral particles described here appear to be similar to those described in C. virginica from the USA and Canada and to those described in C. gigas from Korea and France
Detection of koi herpesvirus (KHV) in koi carp (Cyprinus carpio L.) imported into Ireland.
Peer-reviewedThis report described the first detections of koi herpesvirus (KHV) in the Republic of
Ireland in imported koi carp. In both cases the KHV suspicions were confirmed by
molecular diagnosis and the infected stocks culled.Funder: Marine Institut
Fish Health Unit Report of Activities Undertaken in 2022
This report summarises the activities undertaken by the Fish Health Unit of the Marine Institute in 2022. Regulation (EU) 2016/429 lays down the rules for the prevention and control of animal diseases which are transmissible to animal or humans and the Marine Institute is the Competent Authority responsible for implementation of this regulation in Ireland. The purpose of this report is to provide all stakeholders with an improved understanding of the operations of the Marine Institute in fish health, and the findings encountered by the Fish Health Unit in 2022
Fish Health Unit Report of Activities Undertaken in 2021
This report summarises the activities undertaken by the Fish Health Unit (FHU) of the Marine Institute (MI) in 2021. The services of the FHU, undertaken on behalf of the State, are largely driven by European legislation on aquatic animal health. New EU Animal Health Law came into force from April 21st 2021. Regulation (EU) 2016/429 lays down the rules for the prevention and control of animal diseases which are transmissible to animal or humans and has replaced the regulatory framework provided by Directive 2006/88/EC. The MI is the Competent Authority (CA) responsible for implementation of aquatic animal health regulation in Ireland

Impacto de microvariantes del herpesvirus de los ostreidos 1 en el cultivo de ostra japonesa en los hemisferios Norte y Sur desde 2008
Mollusc farming is the third most productive aquaculture activity in the world, and the Pacific oyster (Crassostrea gigas) is one of the most important farmed species. Since 2008, mass mortalities in C. gigas due to ostreid herpesvirus 1 microvariants have challenged the viability of this industry in Europe, New Zealand and Australia. Ten years after the emergence of this disease, there is evidence that the industry
has become consolidated into fewer, larger companies, with the displacement of small farming enterprises and loss of employment in coastal communities. Rather than seeking technical solutions, the industry has turned to compensatory production strategies, such as increasing the number of spat placed on farms,
higher market prices for table oysters and direct marketing, which appear to have allowed profitability. Biosecurity policies and responses to outbreaks, including those from within the industry, have had unintended consequences for hatcheries and farmers in areas free of disease, mainly caused by restrictions on animal movements, and have not prevented global spread. There may be opportunities
for better coordination of industry and government responses to epizootic disease emergence in aquaculture. There is certainly a need for increased adoption of technical advances from research, once these solutions have been adequately verified.info:eu-repo/semantics/publishedVersio
