Yes, they need full size heated circular rearing tanks to replace the current rectangular ones.
I do not believe the different age classes are spread out.
This year they stocked 55,000 salmon in Winni alone all at once and All in one location. I believe that is approximately 25,000 more than last year yet no one is catching them. As I stated above, in years past I had to make efforts in order not to catch the fingerlings....something is not right. Also if what I am hearing is correct that the current quantity to weight ratio of the smolt salmon is 17 per lb, that is ridiculously small....much smaller than years past!
