Inland marine shrimp aquaculture Kevin FitzsimmonsUniversity of Arizona 3rd National Aquaculture Extension Conference Tucson Arizona April 2003
Introduction • Demand for domestic (wild & farmed) shrimp • Avoid pathogens and parasites • Brackish water aquifers • Inland farms in Texas, Florida, Alabama and Arizona • Maximize water use
Reported benefits • No diseases from infected stocks • Niche market demand • Effluent water used to irrigate crops • Shrimp culture has provided a boost in sophistication of aquaculture production in the state
Shrimp research at University of Arizona • Shrimp research started in early 1970’s • Continues to present • Worked with AZ farmers to rear Specific Pathogen Free (SPF) broodstocks • Production was so good, farmers decided to try growout • First ponds in Aztec and Gila Bend
Shrimp farm in Hawaii • Superintensive (recirculating controlled environment system)
Arizona shrimp farm systems • 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 Mariculture 0.04 ha tilapia ponds 0.1 ha shrimp ponds 5.0 ha shrimp ponds Hatchery tanks and nursery ponds
Shrimp Stage 1 • Acclimation unit - PL’s from 30 ppt to 3 ppt
Shrimp Stage 2 • Nursery pond • Environmental control - covered ponds • Acclimate to farm well water - 1.5 to 3 ppt
Shrimp Stage 3 • Growout ponds (0.1 to 10 ha) • Very low exchange rate • Fed high quality diet with mineral supplements (Az blend)
Arizona results • Intensive shrimp yield - 20,000 kg/ha 2,000 kg in 0.1 ha ponds (five months) • Semi-intensive yield - 7,000 kg/ha 7,000 kg in 1.0 ha pond (five months) • Extensive yield - 2,000 kg/ha2,000 kg in 1.0 ha pond (five months) • Tilapia yield - 2,400 kg in 0.04 ha ponds (eight months)
Shrimp effluent on crops • Low salinity effluent can be used on certain conventional crops with proper cultivation techniques. Sorghum Olives
Conclusions • Still experimental • Production growing • Developed local nutritional blend • Developed local demand for live and fresh product
