Greenland’s coastal cod fishery shows mixed trends in stock levels, according to a new national report. The report is based on 328 responses from active coastal fishermen and is the first systematic collection of their direct observations.
Stock levels vary across regions
41% of fishermen report about the same amount of cod as before. 27% say they see more cod, while 24% say they see fewer.
These observations align with scientific assessments that indicate weaker cod populations north of Nuuk and stronger stocks south of Nuuk.
Climate and whales seen as main drivers
When asked what affects cod stocks, fishermen most often point to climate change. 35% say climate is the key driver. 21% point to whales as a significant factor. Lost gear, fishing pressure and variations in young cod recruitment are mentioned less often.
The ministry notes that fishermen spend far more time at sea than research vessels, and their observations will now be used in conjunction with scientific data in future management planning.
Cod size is mostly stable, but more small fish in some areas
Most fishermen say cod today are the same size as they were one to five years ago. However, more fishermen report smaller cod when comparing to five years ago, suggesting a gradual change over time.
Industry data from East Greenland also show an increase in smaller cod, which some see as a sign of strong new year-classes.
Bycatch stable – but logistics still a problem
The most common bycatch species in coastal cod fishing are wolffish, arctic skate, redfish and spotted wolffish. Most fishermen say bycatch levels are stable.
Eighty-two per cent of fishermen say the number of fishing licences is appropriate.
However, many report problems with delays in collecting live cod from holding cages. 46% of fishermen using cages say collection needs to happen more often to avoid losses.
The ministry says the survey will be repeated annually to monitor changes more closely.
