Jim is right. From the regs:
hatchery trout … in some waters, hatchery
trout may be harvested but wild trout must
be released. In these waters, hatchery trout
are marked before stocking by removal of
their adipose fin (see illustration on p. 10).
Therefore, these hatchery trout must have
a healed scar in place of the missing fin.
If there is anything there that looks like a fin it is not a hatchery fish according to the law and it must be released.
I doesn't matter if it is a clean cut, or if it is 1/2 a fin, or 1/4 of a fin.
not true...
I just spent the past hour trying to get a hold of someone who would give me a definite answer...and guess what?...no one wanted to take the responsibility for being accountable.
here's the list of people and places i contacted:
DFO (Ottawa) 604 666 0384
Vedder River Hatchery 604 858 7227
Capilano Hatchery 604 666 1790
Surrey Division DFO 604 582 5200 (redirected to bio division and hatchery.. Aaron Stotter)
Aaron Stotter 1 800 663 9453 (redirected to Veronica Russell/management systems)
Veronica Russell 604 582 5222 (lower mainland marketing and management systems for fisheries)...redirected (without phone number to Ian Lund)
Ian Lund (wildlife game and fish /field specialist)...no reply redirected to voicemail.
another number given was Gerry Korvo (i forgot what division he was in) 250 756 7128... also grey area for him.
IF IN DOUBT RELEASE THE FISH...but from a legal stand point...according to these "so called" officials...a hatchery fish is marked by the absence of the adipose fin and in its place a healed scar showing a clear lateral line running along the base of where the adipose fin should be...
HOWEVER, they also believe miss clips do occur and in these cases (and they do specify their "personal opinion"...but NOT 100% sure)... the fish constitutes the marking of a hatchery fish.
the only exception is the obvious sign of trauma/laceration/gash/bites (fully healed or not) ... where NO SIGNS OF ANY CLEAN CLIPPING is evident, fish must be released unharmed.
