Fandel, A. Bearzi, M. & T. Cook. 2015. Effects of Ocean Recreational Users
on Coastal Bottlenose Dolphins (Tursiops truncatus) in the Santa Monica Bay,
California. Bulletin of the Southern California Academy of Sciences 114(2):
63-75


Abstract.‹Coastal bottlenose dolphins (Tursiops truncatus) have been
observed in proximity to swimmers, kayakers, stand-up paddle boarders and
surfers along near- shore corridors in the Santa Monica Bay, California.
>From 1997 to 2012, a total of 220 coastal boat-based focal follows of
dolphin schools were conducted in this area to determine a) the type and
proximity of encounters between ocean recreational users and coastal
dolphins, and b) the effects of these encounters on bottlenose dolphins¹
behavior. The majority of encounters involved dolphins and surfers (77.93%,
n=145 encounters), and overall, neutral reactions were observed in response
to encounters (61.93%, n=176 behavioral responses). Interactions between
bottlenose dolphins and recreational users were recorded only once, and
changes in dolphin behavior were observed more frequently when recreational
users were at distances of less than three meters from a school. Although
the current impact of human activities on coastal bottlenose dolphin
behavior does not appear to be significant in the Santa Monica Bay, there is
a need to: 1) adopt a precautionary approach in view of the increasing
presence of ocean recreational users along this coastline, and 2) regularly
monitor these encounters to determine potential changes in the type and
proximity of encounters, as well as changes in dolphin behavioral responses.
