The most helpful regulation change for eliminating a lot of the additional stress, INMO, would be to change the interpretation of a limit and require that once an angler has caught and kept a limit, he or she has to stop fishing. The person who takes a fish to the car, returns and does not reduce a caught fish to possession has broken no law currently.
Also, they don't inject thiamin into eggs. They do add thiamin to the water in which they are being hardened and kept for eye up and hatch, and it absorbs into the eggs by process of osmosis. And they have been giving B injections to adult fish holding for egg take, which produces a noticeable recovery. As the DEC Pathologist said, these fish got hit with a double whammy, high stress alewives containing higher than normal Thiaminase levels, and the predators had to eat more because each alewife was in poor condition and had a lower nutrient level. AND it as the Canadians who pointed out the angling rates at SR as an explanation as to why they did not see this in their large return streams. Another thing reported at SOL was the loss of about 20% of the quota fo eggs taken in Spring 2014, which means redux in stocking in 2015. All of these factors may add up to the old one fish on is a great day that we got used to in the 90's and the crowds thinned then. But this is a put, grow and take fishery, so unless the hatchery operation is predicted to be impacted by angling, I think closures are unlikely (or maybe the LFZ goes away permanently, purely my speculation, but it is a zoo now anyway). Ya pays yer ticket and ya takes yer chances, as TB likes to say. AAAR!
