One person to contact is Dave Beasley who used to work at a place NY that was developing a trophy fishery. Now I think he is based in VA, not sure of the company's name. Someone may be able to help with this info. This is an article that he wrote for Jan-Feb 2009 PBoss magazine: PREPARING YOUR TROPHY FISHERY FOR ANOTHER GROWING SEASON. Dave Beasley provides numerous suggestions for developing, enhancing and maintaining a trophy fishery. Discussed are defining goals, feeder maintenance, harvest, budget, permits, general tasks, population adjustments, best sampling times, RW data, scale samples, equipment checks, spring tasks.
