Abstract:
This dataset contains information on catches reported in the harbours of Santa Catarina state, southern Brazil, between the years 2000 and 2019. Historically, these harbours have concentrated a significant part of the demersal fishing fleet that operates widely on the Brazilian Meridional Margin (BMM), from 21°S to the southern border of Brazilian EEZ (34°S) and from the coastal areas down to 500 m depths. Landed catches were monitored by a research team based on the University of 'Vale do Itajaí' (UNIVALI) along a sequence of scientific projects and contracts developed to meet governmental demands for oceanic and deep fisheries development and management, and in support of the licensing processes of the offshore oil and gas exploration activities.
This catch composition time series shows an annual compilation of total catches discriminated by species caught by trawlers (single trawlers, pair or twin trawlers and double trawlers) and gill net industrial fisheries. These species represent altogether over 81% of total reported catch in the period. The remainder amount of landings was reported as groups of species (e.g. sharks) or categories indiscriminated by species and were excluded from the database.
