Bycatch in the Maldivian pole-and-line tuna fishery.
Tropical tuna fisheries are among the largest worldwide, with some having significant bycatch issues. However, pole-and-line tuna fisheries are widely believed to have low bycatch rates, although these have rarely been quantified.

Reducing flatfish bycatch in roundfish fisheries
Abstract Flatfish bycatch is a concern in many demersal trawl fisheries around the world, especially for fisheries operating under discard-ban regulations. We introduce and assess the performance of FRESWIND (Flatfish Rigid EScape WINDows), a concept for a selection device that reduces flatfish bycatch in roundfish-directed fisheries. The new concept

The general decline of seabird populations worldwide raises large concerns. Although multiple factors are interacting to cause the observed trends, increased mortality from incidental bycatch in fisheries has proven to be important for many species ...

Do Harbour Porpoise Mortality Records Reflect Living Population Structure? A Matrix Population Model Diagnostic [PDF]
Using a matrix population model–based diagnostic, we show that age structures from harbour porpoise strandings, bycatch, and hunting records deviate from demographic expectations, with juveniles strongly over‐represented. These findings demonstrate that commonly used mortality datasets are not demographically representative of living populations and ...

Knowing the fishery to know the bycatch: bias-corrected estimates of harbour porpoise bycatch in gillnet fisheries [PDF]
Incidental captures (bycatch) remain a key global conservation threat for cetaceans. Bycatch of harbour porpoise Phocoena phocoena in set gillnets is routinely monitored in European Union fisheries, but generally relies on data collected at low spatio-temporal resolution or over short periods.

Best Practices for Assessing and Managing Bycatch of Marine Mammals
Bycatch in marine fisheries is the leading source of human-caused mortality for marine mammals, has contributed to substantial declines of many marine mammal populations and species, and the extinction of at least one.

Fisheries bycatch has been identified as the greatest threat to marine mammals worldwide. Characterizing the impacts of bycatch on marine mammals is challenging because it is difficult to both observe and quantify, particularly in small-scale fisheries ...

Cetacean bycatch in Indian Ocean tuna gillnet fisheries
Pelagic gillnet (driftnet) fisheries account for some 34% of Indian Ocean tuna catches. We combined published results from 10 bycatch sampling programmes (1981-2016) in Australia, Sri Lanka, India and Pakistan to estimate bycatch rates for cetaceans ...

Illuminating gillnets to save seabirds and the potential for multi-taxa bycatch mitigation [PDF]
Bycatch in net fisheries is recognized as a major source of mortality for many marine species, including seabirds. Few mitigation solutions, however, have been identified.

Uncertainties about the magnitude of bycatch in poorly assessed fisheries impede effective conservation management. In northern Peru, small-scale fisheries (SSF) bycatch negatively impacts marine megafauna populations and the livelihoods of fishers which
