On larger/older trout and breeding prowess?

Barbed/Barbless hook mortality?

Hand wet/not wet handling?

How long is too long out of water?

Laying fish on bank studies?

Colors trout can see? What is bad color to wear?

Some scientific studies please?

No quoting of famous people please?

some science

Wet hand vs. not wet hand! Click on the fish for the answer.

It has been noted, a can of “Silver Bullet” Coors Light does freighten away most savy trout. However, it has been also noted, a dark brown bottle of Linenkugel Northwest Lager has no affect what soever on trout. It does make one want to curl up on a mossy bank at noon under the spreading shade of a large tree and take a nap. I have taken these notes from my fishing journal, dated Apri 29, 1988. This is as scientific as I can get, and you may quote me since I am not famous and will never be.

I have droves of pages with study of such behavors. If you would like more information I am at your service.

I learn more about the world while talking to myself when fishing alone

caught too many trout to count…

have only caught one trout that looked like that…

It was from the big lake…

lots of standards of fishing…

Are not really standards…

They have just been repeated so many times that is must be true.

Catch & Release mortality study.

As my fly fishing is akin to a religion, I use faith rather than facts; more fun that way. But, I surmise a bit of reality in your quest and although I have no idea why you would want them, I wish you well. I do get involved with ‘fact type stuff’ when it comes to some parts of the game though. Things like line-speed, the DH, negative drift on the back-cast, thorax flies (Marinaro style) and some of the knots I use. So with all of that said, let me take a ‘non-sensical’ approach toward your questions at least.

  1. Bigger and older are better at it, quicker too usually.
  2. Yes they both cause some, one probably more than the other.
  3. Too long out of the water… you bet. Definitely.
  4. Have not found any fish laying anything on any bank. Assumed they laid eggs etc. in the streams. Will look that one up and get back to you.
  5. Color, or in Canada colour. Green.
  6. Scientific studies. Well, you know who to call for that info. The big line maker in Michigan.
    So there, hope I have helped you out some. No need to thank me. Glad for the opportunity.

I work at a university and have access to a ton of journals- most of which I can access online. I did some quick searches for some of the questions that you provided and received mixed results. There is actually a ton of stuff out there but much of it is extremely specific.

For example, when looking into Trout and sight I found: Response features of visual units in the lower midbrain of the rainbow trout & Functional mapping of ultraviolet photosensitivity during metamorphic transitions in a salmonid fish, Oncorhynchus mykiss. A lot of what I found does not seem that useful (neither of these said much about color).

A lot, also, is area or species specific. I would be more than happy to take another look for you to see if any studies were done on the specific species of fish your interested in, or to see if any surveys were done in your area. Just shoot me an email if you like. I?m going to keep looking around simply for personal interest so I?ll make sure to let you know if I come up with anything interesting (I never even thought to look into these databases for fishing information!)

I have read in a ‘journal’ that returning chum salmon, only perceiving black and white while in the ocean, start to distinguish green as they stage off of fresh water estuaries.

Mine don’t live long on the bank as I stomp em them toss em on ice.

Colors trout can see:

“What Fish See: Understanding optics and color shifts for designing lures and flies”
by Colin J Kageyama, OD, FCOVD.
Frank Amato Publications, 1999

Great book!

Why not search with scholar.google.com ?

Searchs online peer reviewed paper… the science. Many of the articles are available in abstract form only, but a trip to the library or university with the reference will often turn up great results.

Search things like “trout temperature feeding” “trout vision” “oxygen requirments trout”
You should get a mess of results.

Found a ton of articles on Google scholar as in the last reply. Type in “Catch and release” for example.

What Fish See: Understanding optics and color shifts for designing lures and flies"

referenced above is a good book. especially for steelhead fishing.
