Catch and release
Q: What’s the best way to release freshwater fish unharmed?
A: The California Department of Fish and Wildlife (CDFW) recommends these five tips:
Land your fish as carefully and quickly as possible.
Try to avoid removing the fish from the water. Underwater unhooking and release is preferred.
Do not squeeze the fish, or touch its eyes or gills.
Remove only those hooks that you can see and remove easily, otherwise clip the line near the mouth on deep hooked fish.
Use artificial lures (no bait) to minimize deep hooking. Barbless hooks or hooks with flattened barbs make unhooking easier and less stressful on the fish.

Q: I saw lots of pintails while duck hunting in the Sacramento Valley this past season. I never had any trouble shooting my one per day pintail limit. Since there seems to be so many pintail, why are hunters limited to just one?
A: While pintail populations may appear healthy and plentiful in California in the fall and winter, habitat loss and other changes in the northern breeding grounds have greatly reduced the continental population of pintails, which has led to the one-bird limit.
Each year, the U.S. Fish and Wildlife Service (USFWS) establishes regulation frameworks for migratory bird hunting. California must set its waterfowl hunting regulations within those frameworks, which state the earliest dates waterfowl hunting may open, the maximum number of days hunting can occur, the latest dates hunting must close, and the maximum daily bag limit.
In California, the California Fish and Game Commission is responsible for adopting annual regulations pertaining to waterfowl hunting including opening and closing dates. Although states must set waterfowl hunting regulations within federal frameworks, they may adopt more stringent regulations. California does this via the Fish and Game Commission.
Northern pintail breeding population indices declined from the late 1970s through the early 1980s. At one time, the continental breeding population estimate was as high as 10 million pintail. However, by 1991 the estimated population was reduced to 1.8 million.
Similarly, recruitment indices (measured by the number of immature birds to adults in the bag) steadily declined. Even with recent record numbers of other dabbling duck species, pintails remain well below their long-term average.
In 2010, USFWS and the Flyway Councils developed an adaptive management framework to inform pintail harvest decisions. The current protocol allows for open season when the observed breeding population is equal to or greater than 1.75 million birds, and either a one or two bird daily bag limit.
For the 2021-22 season, the federal frameworks for pintail allowed for a 107-day season and one-bird daily bag for pintail.
California duck hunters see so many pintails each season because most of the North American pintail population winters in California and elsewhere along the Pacific Flyway. USFWS estimates that hunters in the Pacific Flyway account for about 55 percent of the nationwide pintail harvest.
Q: I recently vacationed in Aptos and found a dead sea otter on the beach. A park ranger said CDFW would collect it because they monitor sea otter causes of death. What typically kills sea otter?
A: CDFW has been monitoring sea otter mortality since 1968 to determine how to best care for injured or oiled sea otters and how to help recover California’s sea otter population. In recent years, the leading cause of death for sea otters has been bites from white sharks.
Sharks bite sea otters to determine if they are prey, but sometimes decide they’re not worth eating because they don’t have blubber like other marine mammals. Unfortunately, most sea otters that are bitten die from their wounds.
CDFW recently reviewed data from more than 500 sea otter necropsies and found that other causes of death include parasitic infections (mostly from land-based parasites) and poisoning by domoic acid.
Investigation of sea otter mortality is supported in part by the California Sea Otter Voluntary Contribution Fund. The public can help by donating to this fund on line 410 of the California state income tax form. Visit wildlife.ca.gov/Tax-Donation for more information.
