What's most firepower for coyotes and skunks?

The following questions were asked on the California Department of Fish & Game (DFG) website:

Question: I live in Imperial County and would like to go coyote and skunk hunting but need to know the biggest caliber of gun that can be used. I do see that for raccoon you may not use a caliber larger that a .22 rimfire. What can I use for coyote and skunk?

Answer: There is no maximum rifle caliber specified in Fish and Game regulations for taking coyotes and skunks (non-game mammals). Fish and Game regulations authorize non-game mammals to be taken in any manner (see section 475 in the Mammal Hunting Regulation booklet). This authorization includes firearms with no further description or restriction, except when hunting within the California condor range where lead ammunition is prohibited (California Code of Regulations Title 14, section 475(f)).

Question: Is it legal to pick up sand dollars on the beaches of San Francisco, with or without a fishing license, even though some are still alive — purple in color with hair (fuzz)?

Answer: If you are in an area where tidal invertebrates may be taken, you may take and/or possess up to 35 live sand dollars. A current sport fishing license is required for anyone 16 years of age or older. A license is not required to pick up empty shells. See section 29.05 in the Ocean Fishing Regulations for a list of areas where it is legal to take fish from the beach/tidepool areas.

Question: What kind of a fishing license is required for a person working in California on a visa from a foreign country?

Answer: A non-resident license, which may cover one, two or 10 days, or a calendar year of state fishing privileges, would be required to fish in state waters for anyone who is not a California resident. For more information, please see www.dfg.ca.gov/licensing/fishing/fishdescrip.html.

Question: Can a felon with a California hunting license and appropriate tags for deer hunting or for any other game legally hunt with a crossbow during rifle season?

Answer: Felons may not possess firearms at any time (firearms are defined in California Penal Code, section 12001(b)). Crossbows are not considered archery equipment or a firearm, but they are considered to be a deadly weapon and can be used during rifle seasons. Department of Fish and Game regulations do not prohibit a felon from using a crossbow to hunt with, however, the person should first check with their parole officer to see if a crossbow violates their conditions of parole.
