520			_aDuring the past few years there has been an inorease in the fishing effort of the small mesh gill net fishery in Negombo and Chilaw areas. There are also indications that the stocks of the Amblygaster sirm (Clupeida) which is the dominant species in this fishery are gradually depleting. The present study was therefore initiated to identify the Ao sirm stocks in these two areas. Material was collected from the small mesh gill net fishery in these two areas and the morphometric measurments were taken in the laboratory. The slope of the linear regressions between the standard length and the morphometric characters were compared by an analysis of convariance oarried out with the help of a micros tat programme on an Apple II e micro computer. The results showed that there were no significant difference between the slopes of the linear regression for Negombo and Chilaw. This indicated that the same stock of Amblygaster sirm is fished by small mesh gillnetters in Negombo and Chilaw areas.
