Mesopelagic fishes are a vital component of the biological carbon pump and are, to date, largely unexploited. In recent years, there has been an increased interest in harvesting the mesopelagic zone to produce fish feed for aquaculture. However, great uncertainties exist in how the mesopelagic zone interacts with the climate and food webs, presenting a dilemma for policy.

- The study explores the impact of global seafood trade networks on the sustainability of fisheries, finding that trade connectivity plays a crucial role.
- An analysis of over 400,000 trade flows and 876 fish species indicates that fragmented trade networks with strong intra-group ties lead to higher biomass levels.
- The research suggests that improved collaboration between fisheries authorities and trade organizations is essential for fostering sustainable fishing practices.
Fishers with individual catch quota, but limited control over the mix of species caught, depend on trade and catch-quota balancing allowances to fully utilize their quota without discarding. However, these allowances can theoretically lead to overfishing if total allowable catches (TACs) are consistently exceeded. This study investigates usage of balancing allowances by the Icelandic demersal fleet over 2001-2017, for over 1,900 vessels.
