Canadian scientists have noted at least two personality types in studies of newly hatched Brook trout, loosely described in lay terms as “Jocks” and “Couch Potato’s.” This shouldn’t surprise any of us – as we’ve been dealing with the human variants since infancy.

“Jocks” feed actively in the water column, and “Tubers” feed in a sedentary manner near the bottom. Interpretation would suggest that the agile fish seek the food, and the more sluggish variant wait for the food to come to them.

It’s likely scientists don’t always have time to follow each other’s research, and coupled with another study that suggests angling selectively targets aggressive fish (Jocks), with the introverts handling much of the reproduction, Brook trout are doomed.

Leaving the species to fat and shy couch potato’s doesn’t bode well for long term survival.

Humans have the wrestled with similar issues; the agile are shipped overseas to be shot at, leaving the sluggish and shy introverts to play video games.  Eventually both groups have to get jobs, which enhances their reproductive viability.

This research explains why the Eastern Brook Trout is the Official Char of the Trout Underground,  throwing those slow bamboo tapers is akin to chumming  for the Couch Potato Brookie, who adore bamboo almost as much as Twinkies.
