No doubt that environment over time (adaptation) effects most traits through selection. The time period for adaptation can be short or long depending on the situation. The point in the studies was that many such traits are heritable.
Aggressiveness in fish while good for fishing may not always be best for survival. Many times the most aggressive fish while small take chances that get them eaten by bigger fish or other predators.
