1 ARAL SEA ARTEMIA POPULATION DYNAMICS PROJECT FUNDING SOURCE: NATO SCIENCE FOR PEACE PROJECT # Economic and Ecological Benefits from Sustainable Use of the Aral Sea Artemia Resource Prepared by: Kakabay Hankuliev Aral Artemia Co. & Brad Marden Weber State University
2 Specific Objectives of Research Document current status of emerging Artemia population Record Artemia population dynamics Identify cyst quality characteristics
3 Commercial Potential of the Aral Sea Artemia Resource
4 Artemia Research Program Both East and West Aral Sea Sampling locations along transect Five transects on West Aral Two transects on East Aral 19 sample locations on West Aral sample locations on East Aral Vertical plankton net haul (2x/location) Sampling frequency: times/month (April-November)
5 Sampling Logistics and Equipment Difficult access causes some modifications in sampling program East Aral only by ATV. West Aral by truck and ATV Lake access by 4-meter rigid-inflatable vessel Former sea bed sediments are highly variable Each ATV expedition = 300 to 500 km.
6 Expedition conditions Poor weather Equipment failure Prolonged delays

26 Economic Concerns: Cost of Production ANTHRAX Substantial transportation costs Unknown Cyst Quality Dependability of Harvest is Highly Uncertain Experimental Harvest is Recommended Commercial Scale Harvest at this time is Counter-productive.
27 ARTEMIA SAMPLING PROGRAM CHANGES FOR 2006 Increased sampling frequency Additional sampling locations on East Aral Measures of cyst quality characteristics Chlorophyll measurements Samples to USGS for nutrient isotope profile Buoyancy tests Less emphasis on West Aral Sea
