Plastic debris is becoming a very prevalent problem for our world’s oceans. In fact two of the ocean’s largest features, the North Pacific and North Atlantic Subtropical gyres, have large patches of anthropogenic debris floating in its waters. There has been a significant amount of research that has found plastic or other anthropogenic debris in the stomachs of sea birds, invertebrates, marine mammals and planktivorous fishes. This debris can be harmful to these species as it can lead to physical entanglement, decreased nutrition from intestinal blockage, suffocation and decreased mobility; plastic can also be a vector for other harmful contaminants. As much research as there is about anthropogenic debris ingestion by the species mentioned, there aren’t many studies about ingestion by large marine fishes. This study set out to study this phenomenon by sampling large, pelagic predatory fishes from the central North Pacific subtropical gyre surrounding the Hawaiian Island archipelago.
Observers from NOAA’s Hawaii Observer Program where placed on commercial long lining vessels were they collected the stomachs of large pelagic fish species from deep and shallow waters. Stomach contents were analyzed back at the lab. Everything in the stomachs was weighed, both prey and anthropogenic debris, and the analysis was even able to weigh the microplastics (

Most of the sport fish caught are pelagic fish and do not live year round in sf bay. its not harmful to eat them. not many salmon are caught in the actual bay like someone said earlier and they are perfectly fine to eat anyways.
its the scrapper fish like croackers and other smaller fish that ingest the shit off the bottom which are harmful. though bigger fish do eat them and the chain is lengthened..it is still such a small trace amount and unless your some person who fishes everyday for dinner which i dought. (not many of those families can afford an internet sevice)
you wont get sick
