| Abstract: | A catch-effort method of estimating fish density and biomass using three small seine nets placed simultaneoulsy to enclose a known area of water is described. The efficiency of capture in the first catch was high for both density and biomass with an overall average of 70 and 69% respectively, and 95% confidence limits of approximately 20% for both. |
