THE CUTTING EDGE � SCIENCE REVIEW

Aggressiveness - it should have been obvious � it�s in the genes

Catchability, how likely a fish is to bite a lure, is a problem encountered by pondmiesters and is often referred to as aggressive fish vs. non-aggressive fish. It has been debated on several occasions on the Pond Boss Forum and articles have appeared in Pond Boss magazine concerning possible management options for fish that don�t bite well. So what are we missing that is so obvious about this aggressiveness trait?


The new study is titled Recreational Fishing Selectively Captures Individuals with the Highest Fitness Potential by David A. H. Suttera, Cory D. Suskib, David P. Philippb, Thomas Klefotha, David H. Wahlb, Petra Kerstene, Steven J. Cooke, and Robert Arlinghaus , in Proceedings of the National Academy of Sciences. doi: 10.1073/pnas.1212536109 , October 26, 2012. This study, using the same genetic line as the first study noted above, found that the trait �catchability or vulnerability to angling� positively correlates with 1) aggression, 2) intensity of parental care, and 3) reproductive fitness.

PS -- there is a lot more to this than the link by salex and the link provided is not the study - only someone else's thoughts about it.
