Genetics and Smart Bass

Probbly not the smartest bass in the lake.

Researchers discovered that catching a bass may have more to do with the genetics of the fish than the skill of the angler.
A genetics experiment conducted on largemouth bass at Heart of the Hills Research Center in Kerrville, had researchers attempting something unusual. They wanted to find out if genetics, passed down through generations, played a role in whether a fish would take a baited hook.

For the experiment, researchers placed 110 bass in a large pond. Each time they caught a fish, they marked it, and then returned to the pond.

At the end of four weeks, ten percent of the bass had been caught three or four times…while 20 percent had never been hooked. These two groups were then placed in separate ponds and allowed to breed amongst themselves. In the end, the offspring of fish that were easily caught… were much more easily caught… than were the offspring of fish that had been hard to catch.

The differences became more noticeable with each successive generation, thus proving that the likelihood of a fish being caught on rod and reel is in fact an inheritable trait.

Now you have something fascinating to tell people at the next gathering you attend.
