For a little while, I wanted to get as far away from government technology as I could. I sure did. Crescent Research Chemicals was a declining business when Rothweiler took it over in 1986. Within three years, he had nearly tripled its sales. For aquaculture, this means therapeutics, antibiotics, anesthetics, whatever.
Major customers are fish hatcheries, aquaria, universities and federal agencies.
Crescent is one of only a half-dozen major players in the game. Rothweiler is wary, of course, but he has the advantage of knowing how to speak government. Which leads us to the Crescent Aquaculture Group. With Rothweiler as chief, this is a bunch of experts he can call in to provide services in fish and shrimp culture, diagnostics and fish health, weed control, water quality, marketing and sales, business management, even site selection and appraisal. The aquaculture and marketing specialist is the well-known George Brooks Jr., who is also busy completing his PhD at The University of Arizona.
