Estimating common dolphin bycatch in the pole-and-line tuna fishery in the Azores [PDF]

PeerJ, 2018
Small-scale artisanal fisheries can have a significant negative impact in cetacean populations. Cetacean bycatch has been documented in the pole-and-line tuna fishery in the Azores with common dolphins being the species more frequently taken.

Estimating Bycatch Mortality for Marine Mammals: Concepts and Best Practices

Frontiers in Marine Science, 2021
Fisheries bycatch is the greatest current source of human-caused deaths of marine mammals worldwide, with severe impacts on the health and viability of many populations.

Impacts of local human activities on the Antarctic environment [PDF]

, 2008
We review the scientific literature, especially from the past decade, on the impacts of human activities on the Antarctic environment. A range of impacts has been identified at a variety of spatial and temporal scales.

Mitigating Seabird Bycatch during Hauling by Pelagic Longline Vessels

PLoS ONE, 2014
Bycatch in longline fisheries threatens the viability of some seabird populations. The Hawaii longline swordfish fishery reduced seabird captures by an order of magnitude primarily through mitigating bycatch during setting. Now, 75% of captures occur during hauling.

Determining optimal pinger spacing for harbour porpoise bycatch mitigation [PDF]

Endangered Species Research, 2013
A trial was conducted in the Danish North Sea hake gillnet fishery in July to September 2006 to determine whether the spacing of the Aquatec AQUAmark100 pinger could be increased without reducing the effectiveness of the pinger in mitigating harbour porpoise bycatch.

Slow sink rate in floated-demersal longline and implications for seabird bycatch risk.

PLoS ONE, 2022
Bycatch of birds in longline fisheries is a global conservation issue, with between 160,000-320,000 seabirds killed each year, primarily through being caught and drowned as they attempt to snatch baits off hooks as they are set.

Mitigating bycatch in Mediterranean trammel net fisheries using species-specific gear modifications. [PDF]

R Soc Open Sci, 2023
Small-scale fisheries (SSF) use static gear which are thought to interact with marine ecosystems more benignly than towed gear. Despite this, trammel nets, one of the most extensively used type of fishing gear in the Mediterranean SSF, generate large amounts of discards, which can account for 25% or more of the captured biomass ...

Mitigating slipping-related mortality from purse seine fisheries for small pelagic fish: case studies from European Atlantic waters [PDF]

, 2019
The release of unwanted catches (UWC) from purse seines, while the catch is still in the water, is known as “slipping”. Once thought to be a benign process, compared to discarding UWC overboard from the fishing vessel, it is now recognised that “slipping”

Cetaceans value and conservation in the Mediterranean Sea [PDF]

, 2015
This review provides an overview of the Mediterranean diversity and conservation status of cetaceans, and the value associated with their conservation and non-consumptive use. Mediterranean Sea is one of the world's diversity hotspots.

High contrast panels and lights do not reduce bird bycatch in Baltic Sea gillnet fisheries

Global Ecology and Conservation, 2019
Bycatch is a cause of mortality among marine mammals, sea turtles, fish and birds. For some species this mortality may be sufficient to cause population declines.
