Report Details

We are filing this report on Mile 99 to document the dead female Salmon Shark (Lamna ditropis) that we found washing up onshore. This week has been very warm, and the wind as been from the south so there is a "down-welling" condition. Also, the water is quite warm, in the 60's. The shark appeared to have been bitten by another shark, but it is hard for us to determine if this was the cause of death or if this was after the shark died.

Human Activities
