A recent article in the Canadian Journal of Fisheries and Aquatic Sciences suggests that fish behavior can play a factor in capture rates. To boil it all down, the fish that are caught in the wild tend to be the “boldest” meaning they take the most chances. These are the fish that tend to venture furthest from the safety of the reef or rocks, which obviously plays a role in increasing their chances of being caught.
What does this mean to us as hobbyists? It isn’t too far of a leap to think that the wild caught fish in our tanks represent a portion of the boldest/riskiest fish of their particular species. And if we are only taking fish with this personality trait, how does this impact the rest of the population and the evolution of their species? LINK
