The Consortium for Wildlife Bycatch Reduction has won the 2013 Katerva Ecosystem Conservation Award!

The Katerva award is hailed as “the Nobel Prize of Sustainability.” The Katerva Award, now in its third year, draws upon a network of experts from science, business, academia, finance, and government to identify innovative projects in ten different categories that have the “greatest potential for both impact and scale” and have the potential to be applied in other locations and situations.

Society of Marine Mammology Symposium 2013

A collection of tweets from #SMM2013 about fisheries bycatch of marine mammals 

The 20th Biennial Conference on Marine Mammals was held at Otago University in Dunedin, New Zealand from December 9 to 13, 2013. Over 1000 scientists came together from around the world for 357 talks and about 400 posters about marine mammals. This year's theme was "Marine Mammal Conservation – Science Making a Difference" and featured a number of talks related to marine mammal bycatch in fisheries.

International Marine Mammal - Longline Bycatch Mitigation Workshop

In October 2013, researchers and fishermen from the United States, Europe, South America, Australia, and the Indian Ocean came together to identify reseach priorities for marine mammal bycatch mitigation techniques in longline fisheries.  

The workshop covered topics such as time-area closures, as well as several methods under evaluation in different parts of the world for reducing the bycatch and subsequent mortality of odontocetes in longline gear, including acoustic deterrents, weak hooks, and net sleeves.Many questions remain in understanding the efficacy of these mitigation meth

Marine mammal bycatch in gillnet fisheries, 1990-2011

Since the 1970s, fisheries bycatch has been increasingly recognized as a factor responsible for reducing or liminiting the recovery of marine mammal populations in many parts of the world. A new study from the Consortium for Wildlife Bycatch Reduction reviews reported marine mammal bycatch from the last two decades. 

Techniques for Reducing Marine Mammal Bycatch in Gillnets

Endangered Species Research Theme Section 


Bycatch in gillnets poses a serious threat to many marine mammals around the world. A new Theme Section in Endangered Species Research evaluates techniques to reduce marine mammal bycatch, including:

Addressing Bycatch in Artisanal Gillnet Fisheries

Workshop report from the 19th Biennial Conference on the Biology of Marine Mammals
 

While most of the research and development of bycatch reduction methods is focused in developed nations and commercial fisheries, some of the most severe coastal gillnet bycatch challenges are likely to be found in artisanal gillnet fisheries in developing nations. Efforts to address challenges in these coastal regions are stymied by a lack of information on the extent of the bycatch problem and the status of the species affected, as well as by social, cultural and economic factors that can cause artisanal fishing communities to resist implementing mitigation measures.

Large Whale Entanglements

Freeing Tangled Leviathans: The Whale Wrangler

Scott Landry, Director of the Whale Rescue Team at the Provincetown Center for Coastal Studies, and a partner on many of the Consortium's research projects, was recently in the Pacific Standard's article The Whale Wrangler.

New type of gillnet may help endangered dolphins

The Consortium's research on barium sulfate gillnets to reduce bycatch of Brazil's endangered franciscana dolphin was featured in the Brazilian newspaper O GLOBO, "Novo tipo de rede promete ajudar a proteger toninhas" 


Bycatch in gillnets is a serious threat to the franciscana dolphin (Pontopoia blainvillei), Brazil's most endangered dolphin. Gillnets are virtually invisible barriers for these dolphins, who frequently get trapped and drown in them. 

Lobster Pot Gear Configurations in the Gulf of Maine

The Consortium for Wildlife Bycatch Reduction has been working collaboratively with the Maine Lobstermen's Association (MLA) to identify innovative fishing gears and methods that are practical for fishermen but also reduce the frequency and severity of large whale entanglements from vertical lines (ropes that extend from the ocean surface to the trap on the ocean bottom).

Shark Behavioral Responses to Deterrents

Jordan, LK, Mandelman, JW and Kajiura, SM. 2011. Behavioral responses to weak electric fields and lanthanide metal in two shark species. Journal of Experimental Marine Biology and Ecology 409(1-2): 345-350.


Sharks are the main bycatch group for pelagic longline fisheries. Shark interactions with fisheries can have negative financial and safety consequences for fisheries and are destructive to shark populations. A product that could deter sharks from fisheries that has no negative effect on the target fish would benefit both fisheries and shark populations.
