Hatchery grown stocked fish usually seem to be a solution for a lot of problems but more often than not – they do more harm than solve any real issues. .
Stocking fish to a river for fishermen to catch for food is really nothing more than just a settlement for all the harm done and a way to suggest people that the fisheries are doing good. But the reality is that when these stockies breed with wild fish the genetic diversity of the wild ones weakens and eventually we end up slowly killing what’s left of the wild populations. .
There’s a place for hatcheries but supporting natural life cycle is the only way to actually get back our healthy migratory fish populations. It’s a rocky road but luckily we have a growing number of people working for this and actually showing numbers of successful restoring programs. .
