1. Inland marine shrimp aquaculture Kevin Fitzsimmons University of Arizona 3rd National Aquaculture Extension Conference Tucson Arizona April 2003

2. 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

3. 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

4. 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

5. Shrimp farm in Sonora, Mexico

6. Shrimp farm in Hawaii F Superintensive (recirculating controlled environment system)

7. Arizona shrimp farm systems F Extensive Semi-intensive Intensive.

8. 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

9. Arizona shrimp production

11. Arizona Mariculture 5.0 ha shrimp ponds 0.04 ha tilapia ponds 0.1 ha shrimp ponds Hatchery tanks and nursery ponds

13. Shrimp Stage 1 F Acclimation unit - PL’s from 30 ppt to 3 ppt

14. Shrimp Stage 2 F Nursery pond F Environmental control - covered ponds F Acclimate to farm well water - 1.5 to 3 ppt

15. 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)

16. Tilapia in supply reservoir

17. 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)

18. Shrimp effluent on crops F Low salinity effluent can be used on certain conventional crops with proper cultivation techniques. SorghumOlives

19. Conclusions F Still experimental F Production growing F Developed local nutritional blend F Developed local demand for live and fresh product
