Abstract

in 1988, we initiated research on cui-ui Chasmisas cujas population dynamics to determine popuiationparameters (popuiation numhrs’ age distribution, recruitrneni and survival) needed to develop “ pop.rt.tionviabiliq/ model’ A systematic netting program was developed to capture cui-ui around b.rafida lake andat different depths- Cui-ui *..“ *“rGa itr, a T-bar “”.h t“g. To d.ate, more than 2oo,oo0 cui-ui havebeen captured with over 130,0o0 ragged. We cr.rrrently have o’ver 5,0o0 recaptures. From 1990 La 1994,estimatesof adultcui-uirangedfrom<oo,0ooto 1,4o0,oc0.

Data from our research effortis still being analyzed and completion of the population viabiliry model is scheduled for Septemb er 1996.
