Marine Advice

The JNCC plays a key role in providing advice for marine nature conservation and the management of the information that underpins this advisory role.


Human uses of the seas are widespread. As a consequence general measures and guidelines are often more useful than an approach that is based on protecting individual sites. These more widespread measures form the basis of much of the marine advisory work of JNCC, which can be divided into three main areas:


  • Fisheries.
  • Offshore industry
  • Species


This site provides some background to current fisheries around the UK, their effects on the marine environment and aspects of fisheries management. There are also copies of the joint views of the UK statutory nature conservation agencies on fishing management, practice and policy.


We also provide advice on many aspects of the offshore industries, including oil and gas, renewable energy and offshore marine aggregates. JNCC provides an advisory service in case of oil spills or other major pollution incidents in UK waters.


Seismic surveys are carried out in the United Kingdom Continental Shelf (UKCS) during the search for, and management of, oil and gas reserves. Surveys do not necessarily pose a threat to marine mammals, but JNCC is consulted on whether consent should be granted for each individual survey.


We also provide advice on the conservation of marine species listed under legislation. They include cetaceans (whales, dolphins and porpoises), seabirds, fish and turtles. We also provide advice to help meet legal requirements to control and prevent non-native species, especially those that threaten native or protected species.


Non-native species are a concern because they may displace native organisms by preying on them or by out-competing them for resources like food and space. Once an invasive species has established itself in the marine environment it is likely to be impossible to remove.
