[quote BassHunter1]Im no bioligist but I thought it was bad to shake them back and forth, they (the fish) don't like water to run backwards through their gills.[/quote]
Not true. Read this lengthy summary of the catch and release studies done:
http://www.wildtroutstreams.com/CatchRel...elines.pdf
An excerpt:
• If there is current, hold the fish upright, facing into the current.
• If there isn’t any current, gently move fish back and forth in the water until gill
movements return to normal and it is able to maintain its balance.
• When the fish begins to struggle, let it swim away
Also:
"To release fish that suffer from depressurization a technique known as “fizzing” has been developed to artificially deflate swim bladders by puncturing the swim bladder with a sharp instrument. In a review of “fizzing”, Kerr (2001) suggested that the practice should be discouraged, as significant damage can result from the procedure, and that fishing deep waters (5-6 m) should be restricted if fish are intended to be released. Kerr (2001) also reviewed several alternatives to “fizzing” for releasing fish caught from deep water. These involved lowering fish
back to the depth they were caught at for release, by means of a retrievable weight or submersible cage (Figure 2). While little investigation has gone into determining the effectiveness of these alternatives, they are recommended over fizzing. To prevent potential decompression, catch-and-release angling for species in deep water should be avoided."
