Kachemak Bay otters' behavior seems unaffected by oyster farms
July 25, 2025
The growing Kachemak Bay mariculture industry and a booming population of local sea otters appear to have a surprisingly uneventful relationship, according to a new 四虎影院 study. The study, published recently in The Journal of Wildlife Management, focused on otters around a handful of oyster farms in the area, comparing their actions to otters that were foraging in nearby control areas without farming. During hundreds of hours of observations, otters weren't seen eating any oysters and the presence of mariculture operations didn't appear to have a notable effect on their behavior.
