In addition to free fishing on public piers, there are 2 free fishing days per year (7/1/2017 and 9/2/2017).

Other than the above scenarios, fishing license is always required.

The majority of the fish species tends to be clean, and safe for human consumption. However, different species have different habits and may be infected from parasites or contaminated from chemical dump to the ocean. Though being very rare, some species of fish can be poisonous. Here are the a list of ocean species around Los Angeles considered as contaminated and not recommended for human consumption:
In addition, smelts are commonly carrying parasites in their meat. Dolphins and Pelicans who swallowed smelts by mistake, are often infected by these parasites as well. Though cooking the meat through can kill the parasites, making the worms not infective to human, many people don't like to consume meat with worms, and choose to release smelts upon catching.
Filleting a fish and examining the meat against sunlight to inspect any worm infection are always recommended. But in general, even though some small infection may exist, the small infected parts of a large fish are usually cut off, instead of completely throwing away a good fish.
Additionally, many cases of food poisoning were reported because of consumption of Cabezon eggs. The venom in the eggs stays effective after being cook through. It is highly recommended to not to eat eggs of a Cabezon.
Depending on where you live, you may need to buy the Ocean Enhancement Validation on your sport fishing license. Fishing in ocean around LA will require the Ocean Enhancement Validation, as required in ocean waters south of Point Arguello of Santa Barbara County.
