 As Told By

 

Bill More: Bill is a shrimp farming consultant and vice president of the Aquaculture Certification Council, which certifies shrimp farms, hatcheries and processing plants.  He got started in shrimp farming in 1962 and spent twenty years in Panama developing one of the most successful shrimp farms in the Western Hemisphere.

David Drennan: David is manager of a shrimp hatchery in the Dominican Republic.  Previously, as a consultant, he worked for many of the most successful shrimp farming operations in Central America.  He owns many “firsts” in shrimp farming.  For example, he was the first person to spawn Penaeus vannamei!  He got started in shrimp farming in 1967.

Yosuke Hirono: Yoshi started his shrimp farming career at a University of Miami/Florida Power and Light shrimp farming project in 1967.  He built Ralston Purina’s first shrimp hatchery in Crystal River, Florida, USA, and had a long career as a shrimp farmer and shrimp farming consultant, mostly in Ecuador.  Currently, he is an aquaculture biologist at Aquatic Eco-Systems, a supplier of aquaculture equipment.

Dennis Zensen: Dennis Zensen was the man charged with building and recruiting personnel for Ralston Purina’s Crystal River, Florida, shrimp research facility in 1968.  Zensen’s management style led to many shrimp farming discoveries in maturation, breeding, larval rearing and growout.  The Crystal River facility and the personnel trained there went on to make a major contribution to the development of shrimp farming in the Western Hemisphere.

Ron Staha: Ron started his shrimp farming career with the National Marine Fisheries Service in Galveston, Texas, in 1970, culturing algae.  Later, with help from Yoshi Hirono, he designed the shrimp hatchery at Agromarina de Panama and then managed it for seven years.  Next he did shrimp hatchery consulting work throughout Latin America, and eventually he build his own shrimp hatchery in Panama.

Harvey Persyn: In 1970, Harvey started his shrimp farming career with Dow Chemical Company in Freeport, Texas, but shortely thereafter, in April 1972, he was hired by Ralston Purina to manage its new shrimp hatchery in Crystal River, Florida, where he became the first person in the world to stock hatchery-reared Penaeus vannamei and grow them to maturity.

Adriano Guerra: Starting at the Ralston Purina shrimp farming project in northeast Brazil in the early 1970s, Adriano Guerra has been farming shrimp for almost thirty-five years.  In this report, he tells a story about the difficulties of doing shrimp farming in Brazil during the early 1970s.  Most recently, he has developed a new aeration system that's being tested on some shrimp farms.

David Flushing: David Flushing worked at Ralston Purina for nineteen years, seven of them at the Agromarina de Panama shrimp farm in Aguadulce, Panama, where he eventually became Director of Operations (Gerente de Operaciones). His recollections provide an interesting look at some of the non-biological challenges of developing a successful shrimp farm in Latin America during the 1970s and early 1980s. He supplied the 29 pictures that accompany the interview. For the full report, click here.
