Marine animal disentanglement

Addressing marine animal entanglement issues through awareness and disentanglement training workshops for fishermen in Scotland.

The Issue

  • Marine animals getting entangled in fishing gear and marine debris can cause injury, impairment and death.
  • In Scottish waters the species most vulnerable to entanglement include minke whales, humpback whales, basking sharks and leatherback turtles. Whales, dolphins and porpoises come under “strict protection” in Scottish law.
  • An at-sea survey found 22% of live minke whales observed on the west coast of Scotland showed evidence of an injury caused by an entanglement.

The Solution

  • The Scottish Entanglement Alliance (SEA) sets out to gather information on the extent and impact of marine animal entanglement, improve reporting rates and provide a platform for fishermen to suggest solutions for disentanglement.
  • SEA worked with fishermen to involve the industry in research and training around marine animal entanglement.
  • This engagement included a weekend disentanglement training course, attended by 22 fishermen and a specialist trainer from the USA.

The Process

  • The fishing industry highlighted that entanglement of a wide range of species was a problem in Scottish waters.
  • The Scottish Marine Animal Stranding Scheme (SMASS)  also saw there had been a rise in entanglement cases in recent years, four in 2014, eighteen in 2018 and fifteen in 2019.
  • Phase one of the SEA project was to establish whether entanglement was an issue, through speaking to fishermen along the coastline and gathering evidence.
  • SEA’s goal is to work closely with the Scottish inshore fleet to better understand the impacts of marine animal entanglements and to develop sustainable, proportional mitigation strategies.
  • Scotland has two long-term monitoring programmes to understand levels of bycatch and entanglements across the UK fleet; there is an on-board bycatch observer programme that is led by St Andrews University, and a strandings analysis programme that is led by the Scottish Marine Animal Stranding Scheme (SMASS).
  • The data collected within these programmes is essential to understand the extent of entanglement. It is important to work in collaboration with fishermen to understand the issue fully and to work together to identify and recommend ways to reduce entanglements.
  • Phase two of the SEA project will cover mitigation measures. The fishing industry are interested and engaged on how this could work, but the SEA Alliance is waiting on funding to be able to kick this off.
