I've only been able to get approximately 60% of the RES of a certain batch feed trained, using a mixture of Optimal Starter #4 and Optimal BG JR feed. This is in a recirculating system.
esshup,
Have you ever tagged any of the feed trained RES to observe how much they outperform the other 40% once they are put into a pond environment?
What is the alternative food source for the non-trained RES in your system? Do you think the non-trained fish prefer that food, are better at capturing it, or are just plain stupid?
