Sea Lion Entanglement and Injury by Fishing Line and Fishing Net

By March 2, 2022March 6th, 2022Sea Lion

Too many times I have come across sea lions entangled and injured by fishing line.  It sickens me.  For each sea lion that survives such a mess, I believe there are many others than do not survive. In fact, I believe many that become entangled in fishing line or nets never even make it back to the surface, held underwater to drown by the deadly gear.  This juvenile sea lion was spotted in La Jolla recently. I photographed it and reported its condition and location to the Sea World rescue program. They had seen it before but had been unable to capture it, and were planning to try again.  I hope they were successful.
