Hi Scott,

This data is pretty standard and represents the most recent data.



I have no idea how the data were collected, but my own personal
experience is that the handling time for release, and that handling time
increases mortality. Some of the papers that site sites tend to confirm
this.

9) Nufer and Alexander, 1992. Hooking mortality of trophy sized wild
brook trout caught on artificial lures.
Study on trophy sized (avg 34cm) wild brook trout.
“ Mortality was 8.3% for brook trout caught on Mepps spinners and Cleo
spoons equipped with treble hooks, whereas mortality was significantly
lower (2.4%,) for fish caught on the same lures with single hooks.

10) Schroder and Kenaston 2002 Annual progress report – Spring Chinook
salmon in the Willamette and Sandy Rivers.
“ Chinook salmon caught on lures with treble hooks had a higher mortality
(11.6%) than those caught on lures with single hooks (4%).”

14) The Doc Fritchley Chapter – Trout Unlimited 2002.
Study on brook and brown trout in the Savage River, Maryland, comparing
single hook flies with treble hooked lures.
Mortality for single hooked flies was 0%, mortality for treble hooked
lures was 8%.
