The impact of lost pots in crustacean fishery - A study from 2016

A study published in 2016 claims that by removing 9 % of the lost traps and pots in a area, the annual crustacean harvest will increase by 27%.

Every year, millions of pots and traps are lost in crustacean fisheries around the world. Derelict fishing gear has been found to produce several harmful environmental and ecological effects, however socioeconomic consequences have been investigated less frequently.

In 2016, there was published a analyzis of the the economic effects of a substantial derelict/lost pot removal program in the United States. By combining spatially resolved data on derelict pot removals with commercial blue crab (Callinectes sapidus) harvests and effort, the study showed that by removing 34,408 derelict pots  (9 %) led to significant gains in gear efficiency and an additional harvest of 13,504 MT. This was a 27% increase above that which would have occurred without removals.

The model results was extended into a global analysis, which indicated that by annually removing around than 10% of the lost pots and traps from major crustacean fisheries, the annually landings could increase by 293 929 MT. This has a value of 831 million US dollars.
