From the 7-county (Bay Area) order issued on 3/16:
10. Definitions and Exemptions.
f. For the purposes of this Order, “Essential Businesses” means:
i. Healthcare Operations and Essential Infrastructure;
ii. Grocery stores, certified farmers’ markets, farm and produce stands, supermarkets, food banks, convenience stores, and other establishments engaged in the retail sale of canned food, dry goods, fresh fruits and vegetables, pet supply, fresh meats, fish, and poultry, and any other household consumer products (such as cleaning and personal care products). This includes stores that sell groceries and also sell other nongrocery products, and products necessary to maintaining the safety, sanitation, and essential operation of residences;
iii. Food cultivation, including farming, livestock, and fishing;
iv. Businesses that provide food, shelter, and social services, and other necessities of life for economically disadvantaged or otherwise needy individuals;
v. Newspapers, television, radio, and other media services;
vi. Gas stations and auto-supply, auto-repair, and related facilities;
However...
Call someone with authority in the area you want to fish. Don't assume--and don't heed the phony patriots who yak about God-given rights (for only their own special interests). They are imbeciles. Most times you will get an okay for shoreline or pier angling. Some areas or agencies, however, are confused and have stubbornly poorly apprised employees; or self-appointed autocrats. Like those who closed Eckley Pier but did not touch Ferry Point or Point Pinole, for example. I was at Ferry Point (not the pier; it was too packed with drunks and stoners) and saw a park policemen yelling at the anglers that they were too close together; and that he would return if more than 20 were on the pier. He never returned and other park employees had no idea what he was talking about. (He also did not mind or notice the poaching and the partying.)
So use common sense. Know the rules before you heed or break them. Do not assume--anything.
