Inland marine shrimp aquaculture Kevin Fitzsimmons University of Arizona 3rd National Aquaculture Extension Conference Tucson Arizona April 2003
Introduction F Demand for domestic (wild & farmed) shrimp F Avoid pathogens and parasites F Brackish water aquifers F Inland farms in Texas, Florida, Alabama and Arizona F Maximize water use
Reported benefits F No diseases from infected stocks F Niche market demand F Effluent water used to irrigate crops F Shrimp culture has provided a boost in sophistication of aquaculture production in the state
Shrimp research at University of Arizona F Shrimp research started in early 1970’s F Continues to present F Worked with AZ farmers to rear Specific Pathogen Free (SPF) broodstocks F Production was so good, farmers decided to try growout F First ponds in Aztec and Gila Bend
Shrimp farm in Sonora, Mexico
Shrimp farm in Hawaii F Superintensive (recirculating controlled environment system)
Arizona shrimp farm systems F Extensive Semi-intensive Intensive.
Arizona farm systems 1. Extensive culture in large ponds 2. Intensive culture in small ponds 3. Intensive culture in lined ponds 4. Semi-intensive culture in unlined ponds
Arizona shrimp production
Arizona Mariculture 5.0 ha shrimp ponds 0.04 ha tilapia ponds 0.1 ha shrimp ponds Hatchery tanks and nursery ponds
Shrimp Stage 1 F Acclimation unit - PL’s from 30 ppt to 3 ppt
Shrimp Stage 2 F Nursery pond F Environmental control - covered ponds F Acclimate to farm well water to 3 ppt
Shrimp Stage 3 F Growout ponds (0.1 to 10 ha) F Very low exchange rate F Fed high quality diet with mineral supplements (Az blend)
Tilapia in supply reservoir
Arizona results F Intensive shrimp yield - 20,000 kg/ha 2,000 kg in 0.1 ha ponds (five months) F Semi-intensive yield - 7,000 kg/ha 7,000 kg in 1.0 ha pond (five months) F Extensive yield - 2,000 kg/ha 2,000 kg in 1.0 ha pond (five months) F Tilapia yield - 2,400 kg in 0.04 ha ponds (eight months)
Shrimp effluent on crops F Low salinity effluent can be used on certain conventional crops with proper cultivation techniques. SorghumOlives
Conclusions F Still experimental F Production growing F Developed local nutritional blend F Developed local demand for live and fresh product
