How science and technology can help save sharks

Every year, Shark Week gives us a peek into the world of shark research and the amazing science and technology developing to study these captivating animals. This year, we were amazed by ultrasounds for pregnant hammerhead sharks and measuring a goblin shark’s bite.  The latest science and technology can also help fishermen seeking other species to avoid sharks, protecting them from a significant source of injury and death while saving fishermen money.

Globally, shark bycatch represents one of the greatest threats – maybe the greatest threat, — to shark populations. Worldwide, sharks caught as bycatch can make up nearly half of the total reported catch, and that’s not counting the large amount of catch that goes unreported. Often, fishermen want to catch more valuable species like swordfish and tuna using pelagic longlines, one of the most prevalent fishing gears on the high seas, and hate accidentally catching sharks instead. So how can science and technology help solve this problem? Read More »

It's risky to start curvina season in the Upper Gulf without sufficient protections for vaquita


Before curvina fishing starts, the Government and fishing sector must urgently adopt additional measures to differentiate legal and orderly fishing from illegal activities, and to demonstrate that the curvina fishery does not interact with neither vaquita nor totoaba.

Fishing for curvina could start earlier than expected in the Upper Gulf of California, without the necessary management measures in place to demonstrate that this fishery does not affect the critically endangered vaquita. EDF has advocated (2016, 2017) for significantly improving management measures, has advised officials and has offered help with implementation. Allowing any fishing activity in the Upper Gulf without necessary measures in place has serious implications. We urge the Government of Mexico and the fishing communities to adopt them as soon as possible. Read More »

No time to lose: Solutions needed to protect the environment and economy of the Upper Gulf

montandoThis piece was originally published in Spanish on February 5, 2017 in El Universal.

The future of the vaquita – a porpoise endemic to the Upper Gulf of California – and the jobs of thousands of people living in the region are in jeopardy.

In recent weeks numerous reports have made public that rampant illegal poaching of the endangered totoaba fish continues – sought for its valuable swim bladder and sold for thousands of dollars in the Chinese black market.

Experts in fishing and environmental issues concur that totoaba poaching in the region is not only threatening the endangered totoaba, but is also the main source of mortality of the vaquita, which is on the brink of extinction. Environmental Defense Fund is seriously concerned about this situation and the equilibrium of the marine ecosystem in the Upper Gulf. Read More »

Electronic monitoring is improving fishery management across the country

EMWorkshop2014

In previous fishery monitoring posts we explored a variety of obstacles to collecting accurate and timely data from vessels in the Chesapeake Bay, West Coast and New England fisheries. These fisheries don’t just have monitoring challenges in common. They also share a solution: each region is piloting an electronic monitoring (EM) or electronic reporting (ER) system intended to make data collection more comprehensive, flexible and affordable. These are not the only regions exploring how new technologies can be integrated into fishery monitoring plans.  In fact, all eight of the U.S. fishery management regions have, or are currently testing EM or ER tools.

In 2013, the National Fish and Wildlife Foundation awarded a Fisheries Innovation Grant to Dorothy Lowman to convene a National Electronic Monitoring Workshop.  Lowman is a natural resource consultant and Chair of the Pacific Fishery Management Council.  EDF cosponsored the workshop, viewing it as a linchpin in bringing fishery leaders together to identify common challenges, and common solutions, to monitoring—one of the most important elements of fisheries management. The workshop facilitated information exchange across regions and helped address outstanding challenges in implementing cost-effective monitoring systems. After more than seven months of planning by a Steering Committee that included fishing industry, managers, monitoring companies and EDF, the National EM Workshop was held January 8th and 9th in Seattle, Washington.   More than 150 fishery managers and stakeholders from across the country attended the workshop along with select representatives from Canada, Denmark and Australia.
