Sea Lion Welfare: Fishery Conflict, Shooting, and Captivity

California sea lions face welfare threats from fishery conflict shooting, entanglement, and poor conditions in marine entertainment facilities.

Key Facts

California sea lions have recovered from near extinction to 340,000 individuals
They are shot illegally by fishers throughout their range despite federal protection
Entanglement in fishing gear causes flipper loss and drowning in significant numbers
Sea lions perform in marine parks globally under conditions that cause chronic stress
Domoic acid toxin from harmful algal blooms causes seizures and death in thousands annually

Welfare Considerations

Sea lions shot by fishers experience gunshot wounds that may not be immediately fatal, causing prolonged suffering before death or rescue. Entangled individuals develop severe lacerations as they grow into the constricting gear. Domoic acid poisoning causes violent seizures over hours or days. Sea lions performing in marine parks spend their lives in small pools, exhibiting stereotypic behaviors. Each welfare challenge is separate but compounds for individuals in degraded coastal ecosystems.

Support the Marine Mammal Protection Act and oppose weakening of sea lion protections
