Right into my wheelhouse :

"Some fish are more prone to be caught and they are the ones removed by both fishermen keeping them or by natural mortality associated with catch and release fishing. Thus leaving a higher % of wary fish either by learning or genetics"

The aggressive fish being caught, with 100+ Relative Weights, should become the foundation of a pond. Do NOT put bass into your pond that fail to meet this criteria. Don't just crack open the wallet for pellet trained fish, Florida strain, or F1's. It's easy to tell a hybrid bass, just look for the camo pattern back. It's hard work fishing for the best, but somebody has to do it !

Better yet, go to the hatchery and buy your bass under the condition you keep the ones you catch & want \:\)

Fire away ... someone will claim those pellet trained bass are more aggressive \:\)
