Location
Location
Location refers to two things:
- Where the fish population or stock lives, e.g., North Sea, or South Pacific.
- Who is managing the fishery. If it says “All areas”, this means that our scoring for management covers the same area as the fish stock.

Technical location
Technical location
A global system is used to split the ocean into different zones, areas, and subdivisions. Each zone is indicated by a number and/or letter. By law, this must be shown on all unprocessed seafood sold in the EU and UK, alongside the fishing method used to catch it. Look for these details on the packet to match your seafood to our ratings.

Hook & line (longline)
Longlining uses a long fishing line with baited hooks. There can be hundreds of hooks on one line. The type and size of the hook, the bait used, and the position of the longline (at the surface, mid-water, or on the sea floor) vary depending on what fishers are trying to catch.
Hook & line (pole & line)
Pole & line, or baitboat, fishing involves a number of rods being set up on a boat. They might be operated by hand or mechanically. Bait is used to attract the target species. It’s also known as one-by-one fishing because the fish are landed onto the boat one at a time.
Pot, trap or creel
Pots, traps and creels are small containers which are left on the seabed for a period of time, and later retrieved by boats. Bait is used to attract animals into them. They are usually made of wire and nylon netting and structured so that animals can enter but not leave. A boat can carry and set out anything from dozens to hundreds of pots at a time, depending on its size.

How we worked out this Rating
Stock status
The size and health of a fish population, or 'stock', that is being targeted by fishermen is a crucial indicator of whether a fishery is sustainable. If the stock is too small to withstand fishing, it is at risk of crashing. We look at how big the stock is, and how much pressure there is from fishing, to assess this. The target level that many fisheries aim for is 'Maximum Sustainable Yield' - the most fish that can be caught year after year whilst keeping the population at a healthy size.
With limited data for Conger eel (Conger conger), an absence of stock assessments and global catches at lowest ever recorded levels, there is concern for stock biomass. UK catches have remained stable, thus no concern for fishing pressure in this area.
Route 2 scoring has been applied to this rating owing to the lack of reference points for fishing pressure and biomass. Conger eel has low resilience to fishing pressure.
European conger eel (Conger conger) is an important commercial and recreational fishing species of the Northeast Atlantic and Mediterranean. The global conger eel fishery peaked in 1994, at 19,036 tonnes. There has been a significant drop in global catches in the last decade, from 18,500 tonnes in 2011, declining 455 by 2019, to 10,139 tonnes. In 2020, global catch reached its lowest ever level (9,507 tonnes) since records began in 1980.
Changes in landings can indicate changes in population sizes. However, there may be other causes, including changes in fishing practices, reduced incentive to catch the species if market value is low, and impacts from Covid. In the UK, MMO data indicates that average price per kg decreased 11% from 2016-2021, from £1.03/kg to £0.92/kg. Over the same period, landings declined 13%. However, there is no comparable data for global catches, and no analysis of the cause of the decline in any fisheries.
There is no data on the population structure and ecology of the species, although research suggests the Northeast Atlantic and the Mediterranean populations are probably separate. Very little information is available about biomass or population trends. In the absence of information about this species, there is concern for biomass.
UK catches have remained around 200 tonnes since 2012. In recent years (2016-2021), average catch in the UK has been 189 tonnes. This represents a relatively small proportion of global landings (1.8%, 2020). As recent landings are below the long-term average, and the UK fishery is a small contributor to fishing pressure on this species, we consider there to be no concern for fishing pressure in this area.
Management
Good management is vital to be sure that fishing doesn't cause fish populations to decline. We look at whether regulations follow the best available scientific advice, how well compliance is monitored and enforced, and whether this is effective in maintaining healthy fish stocks.

Capture method
Environmental impacts of fishing vary hugely, depending on the method used and where it's happening. We look at whether the fishing gear being used could have an effect on seabed habitats, and if so, how severe might this be. We also review whether it catches any other species by accident (bycatch), and what effect this might have on those species - especially if they're Endangered, Threatened, or Protected.
