A project exploring the benthic habitats of the continental shelf of West Greenland to examine the impact of the shrimp trawl fishery.
Fishing is a very important industry in Greenland, so ensuring long term sustainability is essential for both their economy and environment. The northern shrimp fishery of West Greenland is seeking certification of sustainability from the Marine Stewardship Council. As part of this process, researchers at ZSL, in partnership with the Greenland Institute of Natural Resources, are independently assessing the impact of the fishery on the seabed habitats of the area.
The seabed of West Greenland is home to many amazing organisms as well as the commercially important northern shrimp (Pandalus borealis). There are sea cumbers burrowing in the mud, starfish and brittlestars crawling on the surface, the delicate lattice frameworks of bryozoans alongside corals and sponges, to name but a few.
We are documenting and measuring the diversity to compare with fishing activity at hundreds of stations from the southern tip of Greenland, up into the Arctic circle. With these data we will evaluate the impact of trawling on habitats in the region, and provide important evidence to assist in the conservation of these important habitats.
To date, we have taken more than a thousand images of the seabed of West Greenland using a benthic camera aboard the survey vessel M/T Paamiut. You can see some images from these surveys here (Greenland Benthic Images). Some of these images contain hundreds of organisms (our record is more than 600 individuals in one image!). To help us analyse these images we have been working with computer scientists at UCL to develop image processing software.
Surveys of the seabed and time consuming and expensive. We cannot hope to examine more that a small portion of the seabed. However, we can use the limited sampling to learn about the environmental requirements of important habitat forming species. We use these data to develop habitat suitability models to predict the distribution of key species to develop more comprehensive maps of the area.
Tricky trawling game
This fun and informative game teaches about Arctic seafloor animals, the impacts of deep-sea trawling and sustainable fishery. Can you fish without damaging the animals that live on the seafloor?
