The fauna of the Galapagos Island chain is characterized by high biodiversity and endemism. [] Key ResultThe total catch for all sectors from 1950–2010 was 797 000 t, of which industrially caught tuna made up 80%. The results also show a high degree of fishing down within the in-shore 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 Galapagos fishing fleet to areas further off…

Ecosystem effects of fishing & El Niño at the Galápagos Marine Reserve

Comparing ecosystem impacts caused by fishing and El Niño, fishing has had a greater negative impact on bacalao ecosystem role than regular El Niño events.

So Long and Thanks for All the Fish: Overexploitation of the Regionally Endemic Galapagos Grouper Mycteroperca olfax (Jenyns, 1840)

The results suggest the need for bacalao-specific management regulations that should include minimum and maximum landing sizes, slot limits, as well as a closed season during spawning from October to January, to limit the socio-economic disruption to the fishing community during the transition to a more sustainable management regime.

Interactions of tuna fisheries with the Galápagos marine reserve

The largest protected areas of any kind have all recently been established in the ocean. Since 2012, 5 protected areas that exceed 1 million km2 in size have been created, mostly in remote oceanic

International fisheries threaten globally endangered sharks in the Eastern Tropical Pacific Ocean: the case of the Fu Yuan Yu Leng 999 reefer vessel seized within the Galápagos Marine Reserve

A case study that exemplifies how industrial fisheries are likely depleting shark populations in the Eastern Tropical Pacific Ocean is presented, and exposes the magnitude of the threat that fishing industries and illegal trade represent to sharks in the eastern tropical Pacific Ocean.

Catch, bycatch and discards of the Galapagos Marine Reserve small-scale handline fishery

It is found that bycatch contributes to growth overfishing of some target species because they are discarded or used as bait before reaching their first maturity and recommended the implementation of a series of management measures to protect critical life stages of overexploited species and to improve the selectivity of the Galapagos handline fishery.

Unifying the catch data of a divided island: Cyprus’s marine fisheries catches, 1950–2010

The island of Cyprus has been divided since 1974 into the Turkish Cypriot north and the Greek Cypriot south. Here, we have reconstructed the total marine fishery removals for the island in its

Reconstruction of total marine fisheries catches for the Turks and Caicos Islands (1950-2012)

The Turks and Caicos Islands total marine fisheries catches were estimated for the 1950-2012 time period using a catch reconstruction approach, which estimated all fisheries removals, including the




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

Galapagos Islands : a hotspot of sea cucumber fisheries in Latin America and the Caribbean

The sea cucumber fishing activities started in the Galapagos Islands, Ecuador, in 1991 after the collapse of this venture in mainland Ecuador. Although there is only one species (Isostichopus fuscus)

Effects of Artisanal Fishing on Marine Communities in the Galápagos Islands

Abstract: The Galápagos Islands harbor some of the least impacted marine ecosystems in the tropics, but there are indications that local artisanal fishing is affecting exploited marine communities.

Rapid , recent and irreversible habitat loss : Scalesia forest on the Galapagos Islands

  • Environmental Science
  • 2012
The Galapagos biota has suffered few extinctions, due mainly to the late colonization by humans and the high level of protection on most of the archipelago as an uninhabited national park. Thus, the

From Whaling to Whale Watching: Cetacean Presence and Species Diversity in the Galapagos Marine Reserve

Before the Galapagos Archipelago became famous thanks to Darwin’s work on the theory of natural selection, it already was a hub in the global economy as an eighteenth-century whaling ground. Now a

The effects of fishing on sharks, rays, and chimaeras (chondrichthyans), and the implications for marine ecosystems

The effects of fishing on sharks, rays, and chimaeras (chondrichthyans), and the implications for marine ecosystems are examined at the single-species level and through trophic interactions.

Estimating the unreported catch of Eritrean Red Sea fisheries

Unreported catches from three major fisheries in the Eritrean Red Sea were investigated in order to estimate the impact of the total extraction of fish from the ecosystem, which will help the

Past and Distant Whaling and the Rapid Decline of Sperm Whales off the Galápagos Islands

It is generally expected that exploited whale populations should rebuild following the end of whaling. Using photographic identification of individuals during a series of field projects, we studied
