10 Fish Conservation Success Stories to Celebrate

Looking for a good fish story? We look back at some of the year’s best conservation results for fisheries, from alligator gar reintroduction to salmon recovery, with a side dish of fish and chimps.

Fishing, Conservation and Marine Protected Areas: Let’s Work Together

I have a confession to make: I’m a marine scientist who thinks marine protected areas (MPAs) aren’t going to be nearly enough to save our oceans, and that fishing needs to be part of the solution too.

Here’s why: As a conservationist, I’ve seen how MPAs can protect habitat and allow fish populations to flourish, but I’ve also seen how effective fisheries management can balance economic needs with those of a healthy ocean. Within the next generation the global population will reach 9 billion, and it’s our shared challenge to implement the next generation of ocean management techniques to allow us to restore and maintain our oceans against this ever-rising wall of pressure.

That means working together.

Big Fish: Rodent-Eating Trout

As an avid fly fisher, I had heard the stories.

By day, the trout of Silver Creek—a clear, spring-fed stream in southern Idaho—fed on tiny mayflies and caddis flies. The water dimpled as trout sipped the profuse insect life from the surface. People like me used equally tiny artificial flies to try to  mimic said insects, often an exercise in extreme frustration.

By night, though, river monsters ruled: giant brown trout cruised the depths, occasionally surfacing to gulp down any hapless rodents that fell into the stream.

There’s something appealing, at least to an angler, about a trout that attacks mammals. Maybe it’s the thought of our favorite water transforming into a scene from Jaws.

Maybe it’s an antidote to the frustrations of tying delicate flies that practically require a microscope:  If I came back at night, I could just chuck a giant hairball!

But these mice-gulping trout always carried a strong whiff of, well, the classic fishing story. High on drama. Short on fact.

Silver Creek, after all, is one of the most-studied trout streams in the world. And there were no confirmed reports of trout dining on rodents.

Silver Creek also has one of the highest densities of aquatic invertebrates anywhere. The trout surely had easier prey than the occasional mouse.

Then biologists examined some brown trout stomachs.

What they found wasn’t pretty.

But it sure did validate some heretofore questionable fishing stories.
