Something that has happened many times and will probably continue to happen as long as a refinery is in the area. Hopefully local wildlife will see minimal damage but given the proximity to the Ferry Point Pier I wouldn't be surprised if the shoreline rocks are covered in oil or petroleum residue. Locals know best what damage has been done.
Two thoughts, one in regard to take by anglers and one in regard to take by the commercials.
(1) Currently the daily limit for anglers is ten gallons (approximately 100 pounds or 520 fish). That's far more than most people would ever eat or I imagine use in a fishing season if saved for bait. If the possession rule is followed, that one day catch cannot be supplemented by additional herring day after day. Unfortunately when herring runs are on the rules are broken by many people, both the daily take and possession rules. Not by everyone but by many. I think a 20-fish limit would be too low but perhaps the limit should be changed to one five gallon bucket? Of course people will still break the rule.
(2) Then there are the commercial boats that take hundreds of tons of herring (the 2019-2020 quota in San Francisco Bay was 834 tons). When given the contrast in numbers, many would argue that the recreational anglers take is just a fraction of the overall take so shouldn’t they receive new restrictions.
Of course the same can be said in many fisheries and it is one reason the Fish and Wildlife Department has always given far more attention to the commercial fisheries than to recreational angling.
