Fish and shellfish farming

​​​​Fish farming concessions are mainly in the east and south east of the Island's intertidal and subtidal zone, due to the favourable topography and weather conditions. There is also a subtidal concession in St Aubin's Bay.

Disease status of fish, shellfish and crustacea

Jersey has a high health status with regard to fish, mollusc and crustacean diseases. The listed diseases and disease status for Jersey are on our notifiable diseases page.

Control areas for notifiable disease outbreaks

If a notifiable disease is confirmed, Natural Environment (NE) puts controls in place to limit the spread of disease. These are known as confirmed designations.

If your fish or shellfish are in a confirmed designation, you must:

  • comply with any conditions issued by NE
  • get written permission from NE to move fish and / or shellfish and equipment (allow at least 5 working days)

A Jersey Notice of Confirmed Designation has been made for shellfish - Bonamia ostreae.

New Concessions

Natural Environment is responsible for administration and control of the fish farming industry. As crown land is used by the industry it is necessary to ensure wide and comprehensive consultation before a new concession is granted. Those consulted include:

  • the Fisheries and Marine Resources Panel
  • Jersey Harbours
  • the Natural Environment section of the Department of the Environment 
  • members of the public

Marine shellfis​​h farming

The Pacific Oyster, 'crassostrea gigas', currently forms the backbone of the industry with production equalling three quarters of the total production in the UK. Other species farmed are:

  • the mussel, 'mytilus edulis'
  • the scallop, 'pecten maximus'
  • the ormer, 'haliotis tuberculata'

Marine fin fish far​​ming

The only marine fin fish currently farmed is the turbot, 'scophthalmus maximus', at St Catherine’s.

Importati​​on of stock

The Island has EU disease free status which means that any stock imported into Jersey must conform to strict rules. 

Aquaculture production businesses (APB)

Under EU Legislation (Aquatic Animal Health) (Jersey) Regulations 2016, all APBs must be authorised by the Minister for the Environment.  APBs normally include the following:

  • finfish farms
  • shellfish farms
  • crustacean farms

You can download documents from the Public Register of Authorised Aquaculture Production Businesses:

Importers of ornamental fish

It is an offence to operate an aquaculture production business without valid authorisation.

Shell​​fish monitoring

To ensure food safety is monitored in accordance with EU legislation, the Department of th​e Environment funds and carries out sampling programmes of Jersey's farmed shellfish harvesting industry.

Classifica​tion of shellfish harvesting areas

The production areas for bivalve molluscs in Jersey are detailed below. These are controlled by Annex II of Regulation 854/2004.

Classification of bivalve molluscs production areas 2021 / 2022

Sanitary s​urveys

Under EU regulations an assessment of sources of pollution must be undertaken and a sampling plan established for all new shellfish harvesting areas.
