Spatial and temporal variations in seabird bycatch: Incidental bycatch in the Norwegian coastal gillnet-fishery. [PDF]

PLoS ONE, 2019
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 ...

Post-Capture Survival and Implications for By-Catch in a Multi-Species Coastal Gillnet Fishery. [PDF]

PLoS ONE, 2016
As fisheries shift towards ecosystem-based management, the need to reduce impacts on by-catch has been increasingly recognised. In this study the catch composition, discard rate, and post-capture survival of species caught by gillnets in Tasmania ...

Effect of gillnet mesh size on the capture probability and capture patterns in the Asian paddle crab (Charybdis japonica) fishery [PDF]

Heliyon
In the Asian paddle crab (Charybdis japonica) gillnet fishery in the Yellow Sea, China, the minimum mesh size (MMS) regulation has been of a major importance due to high bycatch rates of undersized crabs. In this study, we evaluated how gillnet mesh size

Spatiotemporal distribution and fishing ground driving mechanism of swimming crab Portunus trituberculatus in Hangzhou Bay and its adjacent waters [PDF]

Scientific Reports
The marine ecological environment of Hangzhou Bay and its adjacent waters ( 30°–31° N, 121.5–123.5° E ) shaped by various factors, serves as a spawning and feeding ground for diverse species of fish, shrimp and crabs, including a traditional gillnet ...

Gillnet colour affects catch efficiency in pearlspot (Etroplus suratensis) tropical estuary fishery [PDF]

Aquaculture and Fisheries, 2023
Gillnets are one of the most commonly used fishing gears in both marine and inland waters. Different colour filament nettings are often used in gillnets. However, the effect of gillnet colour on catch efficiency is unclear for most fisheries.

Impact of gillnet soaking time on survival, stress physiology, and muscle quality in Atlantic Cod (Gadus morhua) [PDF]

Animal Welfare
The aim of this study was to investigate the effects of gillnet soak time to gain a better understanding of fish welfare, mortality, stress, and quality (as measured as muscle haemoglobin) during experimental gillnet fishery of Atlantic cod (Gadus morhua)

Bycatch mitigation in the West Greenland lumpfish (Cyclopterus lumpus) fishery using modified gillnets [PDF]

Royal Society Open Science, 2023
Bycatch in gillnets is a global issue and mitigation measures that balance target species catch rates, bycatch reduction and fisher support are scarce. In the North Atlantic lumpfish fisheries, bycatch includes marine mammals and seabirds, and there are ...

Assessing fishery interaction on cetaceans stranded along the Italian coastline between 1986 and 2023. [PDF]

PLoS ONE
Monitoring stranded cetaceans represents a strategic method to assess their health, conservation status, and ecological role in the marine ecosystem. Efficient stranding networks and standardized protocols are essential to monitor this phenomenon and ...

Assessment of Australian Sea Lion Bycatch Mortality in a Gillnet Fishery, and Implementation and Evaluation of an Effective Mitigation Strategy

Frontiers in Marine Science, 2022
Globally, the bycatch of marine mammals in fisheries represents the greatest source of human-caused mortality that threatens the sustainability of many populations and species.

Gillnet selectivity for the north African catfish, Clarias gariepinus (Actinopterygii: Siluriformes: Clariidae), from the Upper Okavango Delta, Botswana [PDF]

Acta Ichthyologica et Piscatoria, 2015
Background. Successful fisheries management requires estimation of gillnet selectivity for optimum exploitation of the resource. In the Okavango Delta, no study has assessed the selectivity of gillnets for Clarias gariepinus (Burchell, 1822) which is an ...
