Guide to the rules and regulations to know before performing sea-fishing activities to supply aquariums and zoos.
Applies to England
Catching marine species
Aquariums, zoos and similar enterprises in the UK source wild-caught marine species for display, research and feeding purposes.
You must have a fishing vessel licence issued by one of the UK or Crown dependency fisheries administrations to fish for profit for sea fish (including shellfish) from a UK vessel. It is an offence to fish for profit from a vessel without a licence. If you don’t have a fishing vessel licence you will need to charter a licensed fishing vessel.
The Single issuing Authority issues licences for all commercial fishing vessels in UK waters.
Any UK boat measuring 10 metres or under which does not have an engine to power the boat, does not need to have a licence and may sell their catch.
Quota, effort and minimum landing sizes
You will have to comply with quota, effort and minimum landing size regulations unless you have a relevant dispensation (exemption). These rules apply even if the vessel is chartered by an organisation on whose behalf the species are collected.
MMO may issue a dispensation to a vessel from certain UK laws for scientific research. Collecting species for supply to aquariums for display purposes will not normally fulfill the criteria for this.
MMO will only consider requests when evidence proves the dispensation is necessary and appropriate for scientific investigation.
Some marine species are protected by international and national wildlife laws from intentional or deliberate disturbance, taking, harm and killing, and in some cases possession or sale. The laws can apply to activities from a vessel and from the shore. MMO will not issue a dispensation for any protected species.
A European marine site (EMS) is any created to protected species and habitats, or birds. You must check whether your activity is restricted in the areas before you collect any specimens.
Some coastal areas are designated as sites of special scientific interest (SSSI) and you must check with Natural England before collecting specimens if any restrictions apply. See the complete list of SSSIs.
A fishing licence is not needed to collect marine species from the shore if you are not using a fishing vessel. You may require a dispensation from an inshore fisheries and conservation authority (IFCA) from their byelaws, which regulate shore and vessel activities within their district. A byelaw may require a permit to carry out certain activities and apply restrictions to, for example:
- minimum sizes of marine species
- type and quantity of fishing gear
- access such as closed periods or areas
Check with the relevant IFCA before collecting specimens.
Buying marine species
It is against the law to buy fish from a vessel that doesn’t have a UK or EU fishing vessel licence unless the vessel does not require a vessel licence.
A buyer must be registered to buy first-sale fish directly from a licensed fishing vessel if it is for display or animal feed purposes.
If you are buying fish second-sale from a registered merchant or fish seller, you don’t need to register.
First-sale fish purchases must be notified to MMO in a sales note within 24 hours of the sale if submitted electronically, or 48 hours in paper format. You can register for free on the Registered Buyers and Sellers Scheme.
An individual or company does not have to register as a buyer of first-sale fish or submit sales notes to purchase shore-caught fish.
