Outdoors Q&A: Properly Catching and Releasing Fish While Taking Photos?

Rule of thumb is to keep hands wet when holding fish out of water for photo-op

Taking photos of fish without putting them at risk can be tricky.

Question: My friends and I are all fly fishermen who promote catch-and-release fishing rather than taking fish for consumption.

Many other fishermen, fishing guides and lodges, as well as most fly fishing magazines, also claim to share this philosophy, but then publish untold numbers of photos of people holding the fish they’ve caught.

Typically, these photos reveal the fish being held for quite a few seconds out of water, and clearly their slime barrier is being broken by the clutching hands.

I wonder how many fish handled in this way ultimately die from the stress of being caught, held out of water and having their protective coating compromised.

While growing up, I was taught if you break the slime barrier, the fish will likely die. Is this true?

Moreover, most anglers I know count successful days of fishing as catching (and releasing) as many fish as possible.

If you consider the increased probability of a fish dying from being caught and held, multiplied by the number of fish caught, there could be a lot of mortality which goes directly against the point of catch and release.

Can you provide some information on this issue? (David W.)

Answer: While many photo layouts suggest prolonged time out of water, it can obviously vary greatly.

According to senior environmental scientist Jeff Weaver, a good rule of thumb is to hold your breath when you lift the fish and get it back into the water before you run out of breath.

Wetting hands before handling fish is probably the most effective method to minimize damage to the slime coating.

Handling fish with dry hands generally removes at least some areas of this protective barrier, subjecting the fish to increased risk of fungal or other infection (though not necessarily mortality).

If extra time is needed to set up the photo or make adjustments to correct for lighting problems, etc., the fish should be retained under water in a net for as much time as possible.

There are four important practices that will help reduce mortality:

1. Keep most of the body of the fish in the water while photographing it, particularly the opercula and gills so they remain oxygenated.

2. Always hold the fish with wet hands underneath the pectoral fins (near the head) and at the caudal peduncle (narrow part just forward of the caudal or tail fin) to avoid injury to the vital organs in the belly.

3. Assuming you have a fishing partner who will serve as photographer, have that person get the camera settings ready and set up the frame of the picture while the fish is retained underwater in a net.

Quickly remove the fish from the water for a picture and return it to the net to rest and respirate for some time, then lift it again for another shot (only if necessary to get a good photo).

4. Always recover the fish before releasing it to the point that it can swim of its own accord and remain upright. If necessary, hold the fish with the mouth facing upstream in an area with adequate flow to ensure thorough oxygenation of the gills.

When transporting turkeys home, which parts are required for ID?

Q: What portions of a turkey is a hunter required to retain for identification purposes?

I’m not sure that “plucking a turkey in the field but leaving the beard attached” is sufficient to stay legal when transporting. While keeping the beard would certainly help identify, I believe a fully feathered head or wing is the actual requirement.

In fact, if a hunter chooses to pluck both wings and leave the “fully feathered head” attached, would that be enough proof for identification purposes? Please advise. (Blake D.)

A: Hunters are not required to retain the turkey’s beard.

However, “all birds, including migratory game birds, possessed or transported within California must have a fully feathered wing or head attached until placed into a personal abode or commercial preservation facility or when being prepared for immediate consumption” (California Code of Regulations Title 14, section 251.7).

Since the law only authorizes the take of bearded turkeys during the spring season, the California Department of Fish and Wildlife (CDFW) recommends leaving the beard attached during the spring season (CCR Title 14, section 300).

How to properly preserve and transport Pacific halibut?

Q: I’m planning some trips this year to fish for Pacific halibut. If we should happen to catch one of any size, what is the legal way to transport a fish if it won’t fit in a cooler? Could it be filleted, and if so, when could that be done?

I’m very particular about preserving fresh fish properly as soon as it’s caught. (Ross B.)

A: You may not fillet your Pacific halibut when on your boat or before you land the fish (Fish and Game Code sections 5508-5509). Once ashore, there are no restrictions on filleting your fish into the size and conformity you want.

Video recording crab traps?

Q: Are there any regulations or restrictions regarding using video cameras (GoPros) on crab traps or lobster hoop nets? (Josh F.)

A: No, there are no fishing regulations that prohibit use of a video camera while fishing.

Noozhawk Asks: What’s Your Question?

Welcome to Noozhawk Asks, a new feature in which you ask the questions, you help decide what Noozhawk investigates, and you work with us to find the answers.

Here’s how it works: You share your questions with us in the nearby box. In some cases, we may work with you to find the answers. In others, we may ask you to vote on your top choices to help us narrow the scope. And we’ll be regularly asking you for your feedback on a specific issue or topic.

We also expect to work together with the reader who asked the winning questions to find the answer together. Noozhawk’s objective is to come at questions from a place of curiosity and openness, and we believe a transparent collaboration is the key to achieve it.

The results of our investigation will be published here in this Noozhawk Asks section. Once or twice a month, we plan to do a review of what was asked and answered.

Thanks for asking!
