Changes in the overexploited demersal fish assemblages in the Northwest Atlantic: the Southern Grand Banks and the Flemish Cap

  title={Changes in the overexploited demersal fish assemblages in the Northwest Atlantic: the Southern Grand Banks and the Flemish Cap},
  author={Adriana Nogueira Gassent},
The Northwest Atlantic fishery is one of the most important Spanish fisheries in distant waters. This region has suffered several collapses of the exploited demersal resources, the latest during the period 1985-1993. The thesis aims to determine the impact of fishing and climate variations on the size and species composition of demersal fish communities in two fishing grounds of NAFO (Northwest Atlantic Fisheries Organization) Regulatory Area (Div.3MNO). We propose to identify, describe and map… Expand


Changes in the exploited demersal fish assemblages in the Southern Grand Banks (NAFO Divisions 3NO): 2002–2013
The Newfoundland Shelf supported one of the world’s greatest fisheries until the main commercial species collapsed more than two decades ago. Wecalculated three ecological indices for individualExpand
Changes and trends in the demersal fish community of the Flemish Cap, Northwest Atlantic, in the period 1988–2008
The Flemish Cap fish community (NAFO Division 3M) has been fished since the 1950s, and major changes in the biomass and abundance of its most important commercial species have been reported since theExpand
Persistence and Variation on the Groundfish Assemblages on the Southern Grand Banks (NAFO Divisions 3NO): 2002-2011
Data from EU-Spain bottom trawl surveys in the NAFO Regulatory Area were analyzed to examine patterns on the South of Grand Banks of groundfish assemblage structure and diversity in relation to depth, finding redfish is the dominant species in the second shallow and intermediate assemblages and Diversity appears inversely related to biomass in the differentassemblages.

Persistence and Variation in the Distribution of Bottom-trawl Fish Assemblages over the Flemish Cap
The aim of this study is to test the variability of the assemblages defined in the Flemish Cap area, and to find out if changes can be related with the constant decrease of the biomass of the main demersal fish species like Atlantic cod and American plaice. Expand
Structure and distribution of demersal fish assemblages on the northeast Newfoundland and Labrador Shelf
Multivariate analysis of 14 years of scientific survey data has distinguished four groundfish assemblage areas on the Northeast Newfoundland and Labrador Shelf. The assemblages were characterized byExpand
Zonation and Associations of Dominant Fish Fauna in Flemish Cap
Data from 682 demersal trawls between 126 and 738 m were made on Flemish Cap in summer during the research surveys in the years 1989-1994. Despite the fact that the depth range for all species wasExpand
The effects of fishing on demersal fish communities of the Scotian Shelf
Since the 1970s, average individual weight of commercially targeted demersal fish on the Scotian Shelf (Canada) decreased by 51% on the eastern shelf and by 41% on the western shelf. For bothExpand
Assessing the impact of fisheries on demersal fish assemblages of the Mauritanian continental shelf, 1987-1999, using dominance curves
The diagnosis of a ‘‘stressed’’ assemblage seems to converge with the results of a similar study conducted off Senegal, but here there was no trend in impact during the period of study. Expand
Temporal changes in the fish community resulting from a summer fishing moratorium in the northern East China Sea
The results revealed that the fish community has undergone a direc- tional change, in terms of relative biomass composition, following the implementation of the morato- rium, with increasing trends in Pseudosciaena polyactis and Lophius litulon and decreasing trends in Pampus argenteus and Acropoma japonicum.

Community structure and diversity of demersal fish assemblages: the role of fishery
Environmental variability and overexploitation, as well as differences in species´ life-history strategies, have both influenced the structure of the demersal fish assemblages found along the depth gradient studied. Expand
