The collapse of Caribbean coral reefs has been attributed in part to historic overfishing, but whether fish assemblages can recover and how such recovery might affect the benthic reef community has not been tested across appropriate scales. We surveyed the biomass of reef communities across a range in fish abundance from 14 to 593 g m(-2), a gradient exceeding that of any previously reported fo...

Marine mammals, as top predators in the marine food web, are sentinels of changes in the oceans and public health. Pollution in the sea and overfishing of seafood resources affects these organisms just as much as it affects human beings. Medics, especially doctors, have an influential reach to patients, and are in an ideal position to get better acquainted with ongoing marine environmental issu...

Impacts of chronic overfishing are evident in population depletions worldwide, yet indirect ecosystem effects induced by predator removal from oceanic food webs remain unpredictable. As abundances of all 11 great sharks that consume other elasmobranchs (rays, skates, and small sharks) fell over the past 35 years, 12 of 14 of these prey species increased in coastal northwest Atlantic ecosystems....

The overfishing of the sandfish Holothuria scabra is increasing due to its various benefits, thus reducing population in nature. This study aimed examine sandfish's length-weight relationship and condition factors on North Coast Sumbawa Island, with sampling locations at two stations, Ai Limung (Pungkit Village), Labu Prajak (Batu Bangka Village). was conducted September-October 2022. A total 1...

Despite different approaches used to assign the risk scores for missing information in productivity susceptibility analysis (PSA)—a widely semi-quantitative assessment tool target and non-target fisheries stocks—for selected attributes of a given species, no formal comparison has been made between scoring terms how well they can predict species vulnerability. The present study evaluated PSA fin...
