Goals for re-stocking hatcheries: Profitability, as always...

摘要

When I was doing my PhD in Atlantic Salmon reproductive strategies, a few decades ago, I had the chance to visit a few very large (for my standards back then) restocking hatcheries. These were operated mainly by power companies obliged to compensate for salmon populations threatened by rivers that had been damned to produce hydro-electric power.Here were great investments in aquaculture infrastructure by companies that had nothing to do with aquaculture, but that were required to invest in order to offset the impact of their core business activities on the environment and on public perception.
