Using a Dinosaur Blind for Waterfowl Hunting?

Question: I realize this may sound like a really dumb question or a joke, but I’m honestly being serious. Can I make a plywood cutout of a dinosaur to hide behind so that I can better sneak up on waterfowl? I recently heard about using a plywood cutout of a cow as a way to approach ducks and geese. However, I then saw that this is illegal in California because hunters are not allowed to use something that looks like a mammal to approach waterfowl. Dinosaurs aren’t mammals though so I don’t see why this wouldn’t work, but I just wanted to ask. (Sydney M.)

Answer: Fish and Game Code, section 3502, which is derived from a provision of the Penal Code dating to 1909, prohibits using “any mammal (except a dog) or an imitation of a mammal as a blind in approaching or taking game birds.” Since dinosaurs are not mammals, you will be ok as long as your blind can’t be confused with a mammal.

Is a SUP considered a vessel?
Question: Is a stand-up-paddle (SUP) board considered a vessel when used in the taking of abalone? I ask because I’m wondering if I have to fill out my abalone tag on my SUP before coming to shore. (Jonathan W.)

Answer: No, you may wait until you come ashore to tag and fill out your abalone report card. Although California Code of Regulations Title 14, section 29.16(b)(1) requires that people taking abalone “shall tag any red abalone either immediately upon exiting the water or immediately upon boarding a vessel, whichever occurs first,” it also provides that people “who dive from a non-motorized vessel such as a kayak that is in the water may wait until immediately after disembarking from the non-motorized vessel to tag and record any abalone in possession.”

Still confused about antibiotics in stocked fish
Question: I just read with interest in the Modesto Bee your answer to the question about antibiotics in stocked fish. The answer doesn’t make sense to me. First, you say that hatchery fish are treated with antibiotics when necessary to save their lives and it is done on an as-needed basis. Knowing that hatchery fish number in the tens of thousands, and no individual fish would be pulled out and antibiotics delivered to just those fish, you must be saying, yes, they are treated, right? And then you finish the answer with “none of the stocked fish have antibiotics.” Huh? (Barbara S.)

Answer: Sorry for any confusion. When the fish need to be treated with antibiotics, then they are treated as a group since most ailments would be ones that would affect them all. Antibiotics are only used when necessary to save lives, and there is a good chance that none of the fish raised during a growing cycle were ever treated with antibiotics at all.

Prior to the Federal Drug Administration (FDA) approving (registering) any antibiotics for use in food fish, they set withdrawal times to ensure public safely. Withdrawal times are meant to guarantee that residual antibiotics are either non-detectable, or lower than the FDA’s acceptable limits, prior to the fish being released.

Once all treatments are finished, the fish are held for the required time for the chemicals to work their way out of their bodies. Only after this time can those fish finally be planted and available for human consumption.

Some other agricultural industries have been criticized for using antibiotics as a growth aid. We don’t do that for the fish we supply to our anglers.

Sport fishing on a commercial crab boat?
Question: Can commercial boats sport fish for Dungeness crab during the sport season when the commercial season is closed? (Anonymous)

Answer: Yes, if the commercial vessel is not engaged in any commercial activity (FGC, section 7856(f)), the commercial vessel does not hold a Dungeness crab vessel permit (CCR Title 14, section 132.1(a)), and everyone taking crab or fishing onboard has a sport fishing license and is following sport fishing regulations.

Why Tag Large Trophy Trout?

Rainbow Trout _RB097

CDFW’s Eastern Sierras hatcheries, especially Fish Springs, have been placing floy tags on broodstock, or super catchable, fish to inform the public that CDFW is stocking larger fish than the usual two-to-four-pound fish. (CDFW photo)

Question: A friend caught a tagged fish in Deadman’s Creek near Glass Creek in Mono County. The tag was on the top fin of the fish, orange in color, about one inch long and slightly thinner than a spaghetti noodle with black printing on it. The message on the tag read: “CA DFW TROPHY – DO NOT REPORT.” What exactly does this mean? (Paul and Gloria W.)

Answer: This was likely a derby fish from Crowley Lake that migrated upstream. According to California Department of Fish and Wildlife (CDFW) Fisheries Environmental Scientist Nick Buckmaster, “CA DFW-Trophy” floy tags are put on broodstock (or any large trout) that CDFW’s Fish Springs Hatchery releases in an effort to show the fishing public that CDFW does stock fish larger than the usual “catchables.” Many of these fish go to “special waters” for tournaments or events.

According to CDFW Fish Springs Hatchery Manager Matt Norris, who oversees the hatchery that stocks Deadman Creek, we do not have record of any trophy trout being stocked in Deadman Creek, but broodstock have been placed into the Upper Owens River and Crowley Lake (downstream of Deadman Creek). In spring many of our Eastern Sierra rainbow trout move into smaller headwater streams (such as Deadman Creek) to spawn, and this may be the case here.

CDFW’s Eastern Sierras hatcheries, especially Fish Springs, have been placing floy tags on broodstock, or super catchable, fish to inform the public that CDFW is stocking larger fish than the usual two-to-four-pound fish.

Crabbing from jetties?
Question: I have a question regarding crabbing on jetties. I have a valid sports fishing license and I am wondering if I can use more than two rods on the Pillar Point jetty? I’ve always thought there are no limits on the number of rods that can be used for ocean fishing, besides on public piers and special targeted species regulations. I will be mainly using crab snares with six loops. Is a valid fishing license even required to fish on jetties? (John)

Answer: If a jetty meets the definition of a public pier, no license is required but there are gear restrictions. “On public piers, no person shall use more than two rods and lines, two hand lines, or two nets, traps or other appliances used to take crabs” (California Code of Regulations Title 14, section 28.65).

“A public pier is a publicly owned manmade structure that has the following characteristics: is connected, above the mean high tide, to the main coastline or to the landmass of a named and charted natural island; has unrestricted free access for the general public; and has been built or currently functions for the primary purpose of allowing angling access to ocean waters. Additionally, publicly owned jetties or breakwaters that are connected to land, as described above, that have free unrestricted access for the general public and whose purpose it is to form the most seaward protective boundary of an ocean harbor are public piers. Jetties, breakwaters, promenades, sea walls, moles, docks, linings, barriers and other structures that are not the most seaward protective boundary of an ocean harbor, are not public piers” (CCR Title 14, section 1.88.)

In this case, the two outermost jetties at Pillar Point Harbor meet the definition of public piers. The inner jetties do not meet the definition as they are not the most seaward protective boundary, and the harbor district currently does not allow fishing from them.

For any jetties or piers that do not meet the definition of a public pier (as in section 1.88), anglers need a fishing license and are able to use as many lines or other appliances as wanted, per regulations.

Documentation needed to collect and keep antler sheds?
Question: I work on a ranch with a lot of property. Among the wildlife on the property, there are a lot of deer. Whenever I hike around I find antler sheds. I was wondering if it is legal for me to take them, and if so, what documentation would I need to keep them? (Lindy K., Sacramento)

Answer: It is legal to collect antlers that have been naturally shed or dropped by deer or elk in California. No documentation is needed to possess them. Keep in mind that everything in nature is recycled. Many mammals, rodents in particular, gnaw on shed antlers as they are valuable sources of calcium and other micronutrients. Recognize that if you remove it from the field, you are denying that source of nutrient. Next time you find a shed antler, inspect it closely and you will often see teeth marks from these animals. Also, be sure to check local regulations because some areas (e.g. most parks) do not allow collecting of sheds in areas under their jurisdiction. Fish and Game Code, section 3039(c) provides the authority to have them and sell them.

Question: How do you tell a hatchery trout from a wild trout in Central Valley rivers? The regulations for the Stanislaus River below Goodwin Dam state you can keep two hatchery trout or hatchery steelhead. Hatchery steelhead have clipped adipose fins. If I catch a trout and it has an adipose fin, do I just assume it’s not a hatchery trout? (Judi A.)

Answer: Hatchery trout or hatchery steelhead are those showing a healed adipose fin clip (adipose fin is absent). Unless otherwise provided, all other trout and steelhead must be immediately released. Wild trout or steelhead are those not showing a healed adipose fin clip (adipose fin is present) (California Code of Regulations Title 14, section 7.50).

Squirrels for crabs
Question: Can legally taken California ground squirrels (a non-game mammal) be used for bait in Dungeness crab traps? (Bret H.)

Answer: Yes, ground squirrels can be used as bait, but remember they are also vectors of a number of flea borne diseases, so use caution when handling them.

Hunting around my house
Question: I live in a rural area. Can I legally hunt within 150 yards of my own residence? Can I hunt within 150 yards of anyone else’s if I have their written permission? (Jess K.)

Answer: Yes. These are safety zone restrictions but as long as there are no other local laws or ordinances that prohibit hunting or the discharge of a firearm, then you can hunt within 150 yards of your own residence or any other residence where you have obtained express permission of the owner or person in possession of the premises (FGC section 3004(a). (LED Feb 14)

Catch and release fishing during a closed season
Question: In the freshwater regulation hand book under Section 1.38 it states: “CLOSED SEASON. That period during which the taking of fish, amphibians, reptiles, mollusks or crustaceans is prohibited.” This leads to my question regarding whether a person can still fish during a closed season as long they release all the fish they catch? In other words, I would practice catch and release and use barbless hooks to protect the fish from further harm. The regulation restricts the taking of fish, but no fish will be taken. I am very confused. Can you help clarify? It’s kind of twisted and confusing. (Robin O.)

Answer: Fishing during a closed season is prohibited, period. Even though you don’t intend to take any fish away with you, the definition of take is to “Hunt, pursue, catch, capture or kill fish, amphibians, reptiles, mollusks, crustaceans or invertebrates or attempting to do so” (CCR Title 14, section 1.80). Therefore, despite your best methods, even the attempt to fish is prohibited.

There are few exceptions, but the take of crayfish other than with hook and line is authorized when a stream is otherwise closed to fishing (CCR Title 14, section 5.35(e)). Typically, crayfish may be taken only by hand, hook and line, dip net or with traps not over three feet in greatest dimension (CCR Title 14, section 5.35). Most crayfish have no limit and the season is open all year. However, Shasta crayfish are protected and so there are specific river and lake closures listed for their protection in the 2014-2015 California Freshwater Fishing Regulations booklet (see page 21), as well as online at http://www.dfg.ca.gov/regulations/. Look for subsection (d) of this section for the closed waters to avoid.

Taking crabs by SCUBA
Question: I am heading to the beach this weekend, I bought a fishing license and I am planning to do some SCUBA diving. Can I take a big bag with me and collect up to 35 rock crabs from the ocean using SCUBA? (Jimmy P.)

Answer: Yes. Take of all crabs of the Cancer genus, except Dungeness crabs, but including yellow crabs, rock crabs, red crabs and slender crabs is allowed all year. While using SCUBA, crabs may be taken by hand only with no hooked devices in possession (CCR Title 114, section 29.80(g)).

The limit is 35 and the minimum size is four inches measured by the shortest distance through the body, from edge of shell to edge of shell at the widest part, except there is no minimum size in Fish and Game districts 8 and 9 (around Humboldt Bay). They may be brought to the surface of the water for measuring, but no undersize crabs may be placed in any type of receiver, kept on the person or retained in any person’s possession or under his direct control; all crabs must be measured immediately and any undersize crabs must be released immediately into the water (CCR Title 14, section 29.85 (b)(c)).
