Subject: LAKE TROUT TAGGING IN LAKE ONTARIO

I would like to know if anyone has any ideas about what type of tags would 
work well for tagging lake trout in Lake Ontario.  We have a slot limit on the 
lake, all lakers between 25-30" have to be released, and I want to start a 
tagging project in the area, mainly to study mortality of released fish (about 
50-65% of lakers caught are in this slot).  The NYS DEC studies on this 
subject are not very conclusive and are basically guesswork, nothing is based 
on actual collected data.  Many charter operators and fisherman are concerned 
over the mortality of released lake trout especially in the summer, where the 
fish are brought up from depths of 120'+ where water temp is in the low 40's 
only to be cranked up and released into 65-70 F surface water, and are at the 
fate of gulls and other scaveging predators.
