New factsheet spotlight: Marine Mammal Bycatch best practices

The Marine Mammal Bycatch Working Group of the Lenfest Ocean Program has released a new factsheet collating best practices for assessing and managing marine mammal bycatch. Bycatch in marine fisheries is the leading source of human-caused mortality of marine mammals globally. According to the Ocean Modelling Forum Marine Mammal Bycatch Working Group, developing quantitative assessments […]

A conservation success story for sea lions

Thanks to a decade long effort by the Australian Marine Conservation Society (AMCS) and Humane Society International (HSI), who collaborated with the government, scientists, and fishers, sea lion bycatch in South Australian fisheries has reduced by 98%. Following a report in 2010 showing that a large number of sea lions were killed in gillnets in […]

Estimating Bycatch Mortality for Marine Mammals

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. Recent regulations enacted in the United States under the Fish and Fish Product Import Provisions of its Marine Mammal Protection Act require nations with fisheries exporting fish and fish products […]

Virtual Panel on Best Practices to Estimate Marine Mammal Bycatch

In 2016, NOAA issued a new rule under the U.S. Marine Mammal Protection Act (MMPA) requiring nations with fisheries that export seafood to the U.S. to adhere to bycatch standards comparable to those of the U.S. The Ocean Modeling Forum’s Marine Mammal Protection Act (MMPA) Bycatch Working Group has developed an array of products and […]

Cost-benefit Analysis for Mitigation Measures in Fisheries with High Bycatch

The Agreement on the Conservation of Small Cetaceans of the Baltic, North East Atlantic, Irish and North Seas, (ASCOBANS), released a new report detailing a cost-benefit analysis for mitigation measures in fisheries with high bycatch. Bycatch is a major threat to cetacean conservation and welfare in European waters. The common dolphin (Delphinus delphis) and the harbour porpoise […]

New framework for marine mammal bycatch best practices

Bycatch in marine fisheries is the leading human-caused source of mortality for marine mammals. It has contributed to the decline and in some cases extinction of marine mammal populations and species. There is a growing need for better assessment of marine mammal bycatch in fisheries, which is set to increase even more with the introduction […]

IUCN Motion Adopted to Reduce Impacts of Incidental Capture

On September 8th 2021, at the IUCN World Conservation Congress, motion 027 – Reducing impacts of incidental capture on threatened marine species– was adopted. The motion calls for, among other things, actions to reduce the bycatch of Endangered, Threatened and Protected (ETP) marine species that is resulting in significant pressure to ETP species. The motion […]

Guidelines to prevent and reduce bycatch of marine mammals in capture fisheries

The Guidelines to Prevent and Reduce Bycatch of Marine Mammals in Capture Fisheries were produced by FAO in response to the request from the Committee on Fisheries at its Thirty-third Session in 2018 to develop technical guidelines on this subject, and are directed at decision-makers, planners, managers and all those involved in developing and implementing policy and technical interventions which relate to the bycatch of marine mammals in fisheries.
