چکیده

2 ABSTRACT The Galápagos Islands are one of Earth's last biodiversity edens. As such, the conservation of their terrestrial and marine wildlife, including the sustainable management of local fisheries, is of paramount importance. Although the commercial exploitation of marine resources in the Galápagos did not begin until the 1930s, issues of overexploitation and mismanagement are already of serious concern. However, to date, research on Galápagos fisheries has been largely species or island specific, and no long-term cumulative catch statistics exist. In this study, total landings associated with the industrial and artisanal fisheries of the Galápagos Islands, were compiled and analyzed in an effort to accurately depict the amount of seafood that has been extracted from this region over the last six decades. The total catch for all sectors from 1950-2010 was 797,000 t, of which industrially caught tuna made up 80%. Our results also show a high degree of fishing down within the inshore ecosystem catch, whereby planktivorous mullets have replaced high trophic level groupers within the past three decades. This shift has coincided with the spatial expansion of the Galápagos fishing fleet to farther offshore , where predatory species are not yet depleted. In addition to legally caught and exported seafood, the Galápagos is also a hotspot for illegal fishing. Of primary concern is the amount of shark finning that has occurred and continues to occur in the Galápagos Marine Reserve, despite attempts at mitigating this ecologically destructive and wasteful practice.

From bonito to anchovy : a reconstruction of Turkey ’ s marine fisheries catches ( 1950 - 2010 )

Turkey’s marine fisheries catches were estimated for the 1950-2010 time period using a reconstruction approach, which estimated all fisheries removals, including unreported landings, recreational landings and discards. We added these estimates to the ‘official’ data, as reported in TURKSTAT, which are also available from the United Nations’ Food and Agriculture Organization (FAO). The total rec...

Fisheries catches from Pacific Island coral reefs are rarely recorded in official statistics. Reconstruction of catch estimates with limited hard data requires interpolation and assumptions, justifiable only by the unsatisfactory alternative of continued substitution of zero catches, a common policy interpretation for ‘no data’. Uncertainties associated with reconstructions are high, requiring ...

1. The fauna of the Galápagos Island chain is characterized by high biodiversity and endemism. Thus, the conservation of its terrestrial and marine wildlife, including the sustainable management of local fisheries, is of paramount importance. 2. Although the commercial exploitation of fish in the Galápagos did not intensify until the mid-1900s, issues of overexploitation and mismanagement are a...

Benin ’ s fisheries : a catch reconstruction , 1950 - 20101

Total marine fisheries catches from the Exclusive Economic Zone of Benin and its coastal lagoons were estimated between 1950 and 2010. The reconstruction considered artisanal and industrial sectors and their discards, subsistence fisheries from the marine and lagoon waters including those generated by women for the first time. Small-scale catch estimates were obtained using catch per unit of ef...

Reconstructed Marine Fisheries Catches at a Remote Island Group: Pitcairn Islands (1950–2014)

The remote Pitcairn Island Group in the South Pacific was designated one of the world’s largest marine reserves in 2016, encompassing some of the few remaining near-pristine areas within EEZ boundaries. Pitcairn’s domestic fisheries are small-scale, and consist mainly of subsistence (non-commercial) and limited artisanal (commercial) catches. There is no locally-based industrial (large-scale co...
