Say someone catches a fish, and would like to photograph it, so they put it in a clean jar with water from where it was collected. What if this person has other work to do before he can get around to photographing the fish? Is it ok to leave it for an extended period of time before photographing, and then releasing it? Or is there a risk of spreading disease?

Holding the fish in its source water and then releasing it back to its capture site should not in any way spread disease, as long as said fish wasn't transported to another site where new water was added.

Interestingly, where I live, even catching a fish and holding it just long enough to photograph and then release requires a State permit.

With water from the same water body that the fish was caught I see no problem with that, however laws are laws.

I've actually been looking at my local state laws and have found nothing on the matter of possessing fish as such.

Alaska just outlawed felted boots worn for flyfishing. Seems there is concern over spreading pathogens such as whirling disease. The new law is very controversial!

Regarding "leaving it in a clean jar for an extended period of time" likely will have a dead fish photo or at least distressed fish photo. It seems best to do what you have to do to get the photo when you get the fish if not keeping it long term. Plan ahead for the fishes sake.

Any Didymo algae aka "Rock Snot" up your way? It's suffocating trout streams in parts of the east and can be spread by waders.

That is probably simply so that proper catch laws can actually be enforced. Otherwise anyone can just claim that they are simply photographing the fish if they do get caught with them.


How long is your extended period of time?

I was thinking around 12 hours...basically...overnight.

I would be worried about that killing fish as well. An hour or two in the bucket while you're out collecting before a photoshoot probably won't be a big deal. Overnight is quite a while to be kept in stressful conditions just to photograph a fish.

To those who may think "whats the big deal" about releasing captive native fish back into their native range, see Elijah's post for a good example. His bluespot sunnies appear to have a Mycobacterium infection that may have come from tropical fish:

Yep, ironically I now believe it was from native bluefin killifish that I bought from my LFS "feeder guppy" tank. I have gone back and found it raging with fish tb. Many of my fish have had to be euthanized in the past 24 hours. It is not pretty, I seem to have caught it as well!
Be very very cautious!
Had Gerald not called it, I may have spread it around by dip-nets... . This particular disease is highly contagious and hard to kill. I have been using antimicrobial soap and special hardcore swimming pool disinfectants to sterilize everything. I have read that using bleach is not enough to do the job. I normally use hot water and salt. This bacteria likes hot water and salt and can be spread to humans and animals. I always learn the hard way!

Various bad stories have been around for years about this infection. Wright Huntley of the AKA had a severe case of it 10 years ago that required serious antibiotics and convalesence to cure. It's the kind of threat most aquarists have no idea about.

Something I've always been curious about - how prevalent is this disease in natural waters?

Not to downplay the seriousness of this topic, but does it have any relevance to the discussion here? Temporarily holding a fish in its native waters and not introducing it to other fish isn't going to cause Mycobacterium that didn't previously exist to spring up. It may stress the fish and cause problems, but it isn't going to pass along a new pathogen that they weren't already exposed to. If the original poster said "I'm going to toss some natives in my tropical tank, then re-release them.", then it would have been a big deal. However, it is a very good warning about mixing fish from various places, not properly quarantining, cross contamination between aquariums, and proper cleaning of your collecting supplies.

The bacteria that cause Mycobacteriosis in fish (several Myco species) are very prevalent in natural waters world-wide (fresh, brackish amd marine), in chlorinated city water supply pipes, and in soil. I suspect many wild fish (and far more farmed fish) are harboring some, but I've never heard of Myco disease outbreaks in wild fish. It probably does kill old or weakened wild fish (if something else doesn't kill them first), but isn't much of a fish health problem except in aquaculture and aquaria. Commercial fishermen get infected sometimes from handling wild fish.

Clayton - You're right, this wasn't exactly a response to the original post (holding fish in a clean container for photo at stream-side). But i often see questions (here and on other forums) from folks wanting to release a sunny, bass, perch, pickerel, etc they kept at home for awhile in close proximity to non-natives. So I thought it was sufficiently related (and important) to post a link. Didn't mean to hijack the topic.

That is a fair point, and I see the logic now.

webMD had a little blurb about the multiple types. To paraphrase is basically said there were at least two forms of M. marinum. One was fairly mild in fish and didn't appear to cross over to humans, while the other was very aggressive in fish as well as capable of being passed to humans though it is much less dangerous to humans than fish. Also according to the site we are in the highest risk category for contact with it due to our close contact with fish. I was unaware that it was even possible to pass on to humans until I looked at your post in the other topic. Kind of neat, and a little bit creepy!

This has been found in the upper part of the Pecos River in NM. I noticed some places are starting to not sell felt soled waders.

Not Good ! I think the other persons advice is very good. "Plan ahead". I see no reason a person should hold a fish for 12 hours just to photograph it. I mean have your photo tank with you, take a photo and put it back into the water it just came out of. I suppose depending on the fish, I would think it would be a dead fish either before you photographed it or after you let it go.

It is good to be nice to fish as a fish hobbiest. Regardless of any law I feel that one should also take good ethics to the stream or body of water with him.

My two cents worth again,

Daniel
