Can vertical separation of species in trawls be utilized to reduce bycatch in shrimp fisheries?
PLoS ONE, 2021 Several shrimp trawl fisheries use a Nordmöre sorting grid to avoid bycatch of fish. However, small fish can pass through the grid. Therefore, the retention of juvenile fish often remains an issue during shrimp trawling.

Polar cod egg and larval drift patterns in the Svalbard archipelago [PDF]
Polar Biology, 2019 AbstractSpawning of polar cod (Boreogadus saida) in the vicinity of the Svalbard archipelago has not been directly observed. From the distribution pattern of polar cod 0-group observed during annual monitoring of the Barents Sea, it has, however, been inferred that spawning occurs in Svalbard waters most years.

Key processes regulating the early life history of Barents Sea polar cod [PDF]
Polar Biology, 2020 AbstractThe polar cod (Boreogadus saida) in the Barents Sea is one of the main stocks of this species in the Arctic, reaching a total biomass of almost 2 million tonnes in some years. It has been fluctuating considerably in abundance, and in recent years, it has been at a low level.
