Antibiotics in Hatchery Fish?

Trout planting_CDFWQuestion: I would like to fish at a local stocked pond. Do the California Department of Fish and Wildlife (CDFW) fish that are stocked there have antibiotics in their systems? Are they fed antibiotics on a routine basis or even on an occasional basis? I just want to be sure any fish I’m catching will be safe to eat. (Connie S., Big Pine)

Answer: CDFW hatchery fish are treated with antibiotics when it is necessary to save their lives. According to Dr. William Cox, CDFW Program Manager of Fish Production and Distribution, this is done on an as-needed basis and using only antibiotics that are approved and registered by the US Food and Drug Administration (FDA) for diseases listed on the label and in fish species approved. This is all done under veterinary prescriptions by CDFW veterinarians. To be approved by the FDA, there are many hurdles to prove human food safety, animal safety and environmental safety. These are all met in the process of becoming registered. So to answer your basic question, none of CDFW’s stocked fish have antibiotics when they are stocked for anglers. They are perfectly safe to eat.


Steel shot for chukars
Question: A friend told me that we are now required to use steel shot when hunting chukars (Red-legged Partridge). Is this a new regulation? Since these are introduced non-native birds, why shouldn’t they be treated similar to the Eurasian doves? Please let me know because I would not want to get a ticket. (Chris J.)

Answer: As you may know, we are in the middle of a transition to nonlead ammunition for all hunting in California. As of July 1, 2016, nonlead ammunition is now required for all hunting on CDFW wildlife areas and ecological reserves and when taking upland game birds with a shotgun, except for dove, quail, snipe and any game birds taken on licensed game bird clubs. In addition, nonlead shot is required when using a shotgun to take resident small game mammals, furbearing mammals, nongame mammals, nongame birds and any wildlife under the authority of a CDFW depredation permit.

In regards specifically to chukar (which are related to Red-legged Partridge but a different species), you are required to use nonlead shot when hunting them with a shotgun from this season on unless you are hunting at a licensed game bird club.

According to CDFW Upland Game Bird Senior Environmental Scientist Karen Fothergill, there is no species-related or ecological reason for the manner in which we are phasing-out lead ammunition. Rather, in order to implement the nonlead legislation in a way that is least disruptive to hunters, we coordinated question and answer sessions at sportsmen’s shows, held meetings with hunting organizations, hosted a series of public workshops throughout the state and sent letters to major ammunition manufacturers before we finalized the implementation plan.

Filleting sheephead at sea
Question: I was recently told that I could not fillet a sheephead aboard my vessel since they do not have a minimum fillet length but do have a size limit of 12 inches (California Code of Regulations Title 14, section 27.65).

My question is whether it still applies for a large sheephead if the fillet was longer than the 12-inch size limit? I am assuming the reason for not allowing sheephead to be filleted aboard a vessel is because it is difficult to determine the overall size of the fish from the fillet. However, if the fillet is greater than the minimum size limit for the species, it would seem like there should be some type of exception to the no fillet rule, or perhaps there is another reason I’m not considering?

Answer: Only those species listed as allowed to be filleted may be filleted on a vessel. Since California sheephead have a minimum size limit of 12 inches total length but no fillet length specified in the regulations, they may not be filleted while on any boat or brought ashore as fillets, steaks or chunks (CCR Title 14, section 27.65).

If you think this regulation for California sheephead should be revised to allow for a minimum fillet length allowance, you are welcome to bring a proposal before the California Fish and Game Commission for consideration.


Use of blue tarp with decoys
Question: Can I use a blue tarp and place dove decoys around it? I’m hoping the doves will think the blue tarp is water and will be attracted to fly over or land near the decoys. (Anonymous)

Answer: Sure, you can give it a try!
