We have known for some time that fish grow faster in a dam (Americans read pond/lake) than they do in the hatchery. A hatchery you see, is a business enterprise. And a business enterprise had best watch its feed conversion ratio if it wants to be successful. In other words the level of feeding required for an optimum feed conversion ratio, is not the same thing as the feeding required for maximum growth rate.
I lay in bed this morning, as the rain pattered on the roof, thinking as one does, about exactly where to spread our “winnings”. We have all, I am sure day- dreamed about how exactly we would spend our lottery winnings. A new truck, a couple of bamboo fly rods, a few trips to exotic fly-fishing locations reachable only by helicopter: Kamkatchka. New Zealand. Alaska. Maybe Mongolia for Taimen. That sort of thing. But our winnings this time are real winnings. They are Trout. Hatched Trout, and thousands of them.
Thousands of them!
We had a good year at the hatchery this year you see, and we have a last batch of some twenty odd thousand fry, that need to go into the dams tomorrow.
