I truly think this whole Hypothetical situation has offset the purpose of this thread.That being the unfortunately common pratice of taking Wild fish into captivity until they get to big (or one gets tired of them) and then they are dumped.

As stated...In this situation really there is little real impact that can occur from it. (Myself I would discourage it regardless).

I personally find a very different ethical situation that arises out of the hypothetical situation and this has more to do with concepts of environmental education rather than the topic.

This is exactly what I was trying to point out. While we as collectors should not release our charges back out into the wild, I felt that the thread was getting a little too restrictive, such as in the following quote from above somewhere: "Only return it to same waters *immediately* after catching it. Taking it home and then returning it is a no-no."

My point was that there are no absolutes in anything, and in some cases it might be more ethical to take the fish homehome and then return it. Just trying to interject a little balance.

This is *law* in most states.

Even though your hypothetical sitation may seem ethically right, it is still against the law.

Righto. (Actually, I don't know the law for most states). I'm not questioning the law here. Just pointing out a situation that may go against what the first group of posts were saying. As someone who enjoys teaching kids about nature, I felt like the educational value should be brought up.

regardless, there is a diffrent awnser to every situation. Does the kid take responsibility well? Will she know not to do this often or ever again? The point is in general the capture and relise is bad because it can cause desease and other problems.

This isn't hypothetical. I take fish from the water put them in a bucket until I've found as many species as possible. I then take pictures of them and then release them (naturally in very water they came from). This can take a few hours or more to do.
Is this ethical?

yes...I would however urge you to disinfect your buckets and photo tanks though between watersheds.
Thats not being paranoid BTW that is just being carefull. I personally do this with all collection and holding equipment.

is letting it dry out completely enough?

or do we need to be doing a bleach dip?

VIniger water is best because bleach could kill your fish even it tiny ammounts.

What do you use for field disinfectant, when moving from site to site?

Normally either Fritz Net-dip or Virkon. I like the Net dip for field work as it is generally good to go with just drying and it does not require rinsing. This makes it a bit easier to use.

How can I get Fritz net dip or Virkon?

Actually I ment to send you this link awile ago, this is where I get the bulk of my collecting and fish room supplies from.
Might help you in your up-coming project.

Virkon is rather expensive stuff. I don't feel like dropping nearly $100 for it. Does anyone have a similar product that would do the trick?

Does anyone know the answer to this? Would this work for the kind of nasties that we are talking about?

I suppose the answer also depends on what part of the country you are in.

Also, Blaze88 mentioned vinegar. Anyone have any thoughts? Wouldn't that be fabulously cheap if it worked?

I personally do not think that drying is enough, many of the nasties out there can encyst or become dormant.
What part of the country you are in can definitely determine how much one should pay attention to things like this. For example I would throughly disinfect any equipment that has come into contact with any area known for an outbreak of disease or if someone was in Zebra mussel land then went to an area not known to contain them.

Vinager I'm not really sure is strong enough to really do much at all.

Virkon is rather expensive stuff. I don't feel like dropping nearly $100 for it. Does anyone have a similar product that would do the trick?



Try the Net-dip stuff.. it is much cheaper and IMO easier to use in the field. I normally only use virkon in getting back from the field or from a collecting trip.

A 1:10 dillution of bleach is also effective but I have found it to be difficult to use in the field without having to rinse equipment down throughly and dry it out between use.

I hope we're not flaming people here. I would like to think we're simply letting others know how passionately we feel about the release of fish, any fish.
In your scenario I would not do it unless the following conditions were met: The fish bowl was sterile (and I mean sterile not a quick rinse in the sink) and only water from the lake used to house the fish. Since both of these things are pretty easy to do, I would say this is a go. Others may feel differently but this is a FORUM. Open ideas and thoughts should be shared it's the whole point of this place. Sound like a neat sleep over (for those outside the bowl) :) .
And I think those that release store bought minnows into the water should be made to eat a pound of live minnows everyday for a year.



I am a newbie to the native side (collecting) of the aquarium hobby so I may be wrong (wouldn't be the first time). I understand all the reasons listed above but if even releasing a few minnows that were kept in a container for a few days that was "not sterile" into the same water is a contamination risk than wouldn't using collection gear (nets, etc.) that have been in several different waters, allowing humans wearing items (bathing suits, collecting clothes/waders) that have been is different waters into the water, allowing fisherman to use gear that has been around or bait that comes from who knows where (I think you get where I am going) all that I am pretty sure has not been sterilized after each use all a much greater risk? I don't mean to be sarcastic and I hope this isn't taken that way. I am just a little confused (wouldn't be the first time).

There is nothing wrong with bleach, as long as it has been rinsed and had sufficient time to dry. You can also buy Muriatic Acid from Lowe's or Home Depot. Either one would sterilize an aquarium or nets sufficiently.

Anytime I re-use an aquarium, I will use muriatic acid to remove calcium build up, and then bleach the tank. Many people have done this for quite a long time with no ill-effects.

Gear and the likes, are all able to transmit nasties if they are immediately re-used in another location. Boats seem to have the nasty habit of introducing things--from zebra mussels in the Great Lakes, to Calupra taxifolia off the shores of California. I see little harm coming from observing fishes for a few days in their own tanks, and then returning them--as long as great care is taken not to introduce more nasties to your local waters than are already there.

Just my 2 cents.

Always learning. Glad to hear that collecting equipment does get cleaned. Hope all are doing this.

I may have hit this topic late, but I have a question.

Sick or infirm specimens should be euthanized in a humane manner and disposed of properly.

What are some humane ways to euthanize fish?
