New Technology Aims to Protect Whales from Fishing Gear Entanglements

The Problem of Whale Entanglements

• 🐋 Entanglements in fishing lines have significantly impacted marine mammal populations, contributing to humpback whales being on the endangered species list.
• ⚠️ Since 2007, approximately 922 endangered humpback whales have died or been maimed due to ropes from fishing gear, according to NOAA.
• 🎣 Traditional crab fishing methods, used for over 170 years in San Francisco, rely on long lines of rope that pose a severe risk to whales.

Innovative Pop-Up Gear Technology

• 💡 A new remote-controlled pop-up balloon-like device is being tested to signal crab cages on the ocean floor to ascend to the surface.
• 📡 This technology utilizes an acoustic release system, with a transducer sending a signal to the release unit, originally developed by the military.
• ✅ Fisherman Bran Little is pioneering this pop-up gear, aiming to retrieve his crab cages without harming whales.

Challenges and Adoption in the Fishing Industry

• 💰 The new technology comes with an additional cost of $50 per cage, which is a significant hurdle for an already cash-strapped industry.
• 📉 Many fishermen have faced numerous losses over the decades, making them hesitant to adopt new, expensive technologies.
• 🗣️ Some fishermen, like Bran Little, were initially skeptical of the pop-up gear but found it to be feasible and effective after testing.

Regulatory Measures and Future Outlook

• 🗓️ California's Department of Fish and Wildlife has shortened the crab fishing season due to the heightened risk of migrating whales.
• 🐳 Whales follow their food source, krill, closer to shore, increasing their proximity to fishing gear.
• 📈 Bran Little has invested $25,000 in the pop-up technology and hopes to continue fishing successfully while protecting whales.
