The biggest threat to the California Short Beaked Common dolphin population is the drift gill net fishery here. They are the most frequently killed cetacean species by the California drift gill net fishery.
Short Beaked Common dolphins are also affected by; ocean pollution (plastics, heavy metals and chemicals), noise pollution and habitat degradation.
Currently a bill to ban the drift net gill fishery practice is working its way through the levels of government. This may be the largest single action to ensure healthy populations of Short Beaked Common dolphins in San Diego and California.
