Sustainable fisheries management is key to restoring and maintaining ecological function and benefits to people, but it requires accurate information about patterns of resource use, particularly fishing pressure. In most coral reef fisheries and other data-poor contexts, obtaining such information is challenging and remains an impediment to effective management. We developed the most comprehens...

the native fishes of springs, ghanats and caves of iran are uniquely significant, since they are rear and, because of pollution, dryness, . purposeful or accidental introduction of exotic species and over all, because of industrialization are in danger. the stock of valuable fishes of iran are declining while they have not been completely identified. the stock of these fishes, particularly thos...

Shark take, driven by vast demand for meat and fins, is increasing. We set out to gain insights into the impact of small-scale longline fisheries in Peru. Onboard observers were used to document catch from 145 longline fishing trips (1668 fishing days) originating from Ilo, southern Peru. Fishing effort is divided into two seasons: targeting dolphinfish (Coryphaena hippurus; December to Februar...

We found that concentrations of nitrogen (N) in the stomach of voles varied between forest sites. Concentrations of nitrogen as well as the ratio of nitrogen to carbon (C) in stomach content were not different between the sexes or with season. Body mass varied between sites and between seasons but were unrelated to N concentration in spite that the body mass of voles in the spring season were o...

14 We report analyses of a dataset spanning 38 years of near-annual fishing for Antarctic toothfish 15 Dissostichus mawsoni, using a vertical setline through the fast ice of McMurdo Sound, 16 Antarctica, 1972-2010. This constitutes one of the longest biological time series in the Southern 17 Ocean, and certainly the longest for any fish. Fish total length, condition and catch per unit 18 effort...

Tropical rainforest regions are urbanizing rapidly, yet the role of emerging metropolises in driving wildlife overharvesting in forests and inland waters is unknown. We present evidence of a large defaunation shadow around a rainforest metropolis. Using interviews with 392 rural fishers, we show that fishing has severely depleted a large-bodied keystone fish species, tambaqui (Colossoma macropo...
