The deep sea is the world's largest ecosystem, with high levels of biodiversity and many species that exhibit life-history characteristics that make them vulnerable to high levels of exploitation. Many fisheries in the deep sea have a track record of being unsustainable. In the northeast Atlantic, there has been a decline in the abundance of commercial fish species since deep-sea fishing commen...

Bottom fisheries: These are generally for groundflsh species such as rockfish, cod, and sole, which are caught by bottom trawling, the fishing practice of dragging large nets weighted with chains, rollers, or rock-hopper gear across the seafloor. Trawling is the fishing practice most destructive of marine habitats. regulatory agenci to generate these quota which ideall hould make fisheries sust...

Bottom trawling is associated with negative external effects such as seafloor pressure and high fuel use. Replacing bottom trawls passive gear, creels, therefore interesting for policymakers. We investigate the response of Norway lobster fishery in Sweden to an expanded creel area. Using economic model (FishRent), we analyse fleet structure, net present value two environmental indicators under ...

Bottom trawling is a common fisheries method and also widespread scientific sampling for benthic demersal species. Selectivity catchability are usually estimated using different meshes studies with alternative methods rare. In this study, to improve the estimation of trawl selectivity, we compare bottom catches recordings made by camera fitted on top net. Scientific was conducted along Northeas...

Bottom trawling causes widespread disturbance of sediments in shelf seas and can have a negative impact on benthic fauna. We conducted a large-scale assessment of bottom trawl fishing of benthic fauna in different habitats, using a theoretical, size-based model that included habitat features. Species richness was estimated based on a generalized body mass versus species richness relationship. T...
