As a few guys who have seen this thread may know, I have set myself a personal goal (amongst other fishing challenges) to catch ten wild-caught freshwater fish species over the 100 lb/45 kg mark.
I managed alligator gar to 206 lb's and short-tailed river ray to 240 lbs (estimated, based on diameter etc) in 2013. In 2014 I was lucky enough to catch Nile perch to 160 lb's, Piraiba catfish to 150 lb's, and arapaima to 240 lb's. 2015 saw my get my best accomplishment of this challenge thus far - a 130 lb goonch/giant devil catfish and a 300lb plus giant freshwater stingray in the first 6 months of the year - photo's all in this thread and earlier posts.
in Mid-2016 I had another trip lined to target white sturgeon in the US (not Canada, my hunch was I knew a few rivers with fish just as big as well as less fishing pressure). Sadly, upon arrival there was a severe drought in the region, and they had closed the sturgeon fishery in the stretch of the river where the true giants live (below a dam), to ensure they don't suffer mortality. I must say, despite the obvious disappointment I do respect the US authorities for making such decisions, and preserving their aquatic resources. Theoretically the high temp's make the fish more likely to suffer handling stress and they had already encountered some 'unknown mortality' in their sturgeon population, so decided it a wise move to make the call for an emergency closure to the fishery.
We had to console ourselves with fishing a lot further downstream, essentially an area where numbers of fish are up, but size is way down on average. This proved to be true as you could notch up 20-30 fish days (sturgeon!) but they would average 20-50 lb's - juveniles by sturgeon standards.
Despite the many small fish, my girlfriend and I managed to take some semi decent fish - my biggest at around the 150 + lb mark - taping out at about six and a half to seven feet. By no means what I could call the size class of fish I wanted, but hey, it was 'number 8' on my list so mission accomplished (although I feel the need for a return trip on this one to get a true monster).
