Estimates of Hard Clam Abundance from Hydraulic Escalator Samples by the Leslie Method

The feasibility of predicting hard clam abundance in a sample area from subsamples collected with a hydraulic escalator was investigated. Seven experimental plots, each about ½ acre in size, were sampled and then completely harvested. The error for the difference between estimated abundance and tota...

Zusammenfassung:The feasibility of predicting hard clam abundance in a sample area from subsamples collected with a hydraulic escalator was investigated. Seven experimental plots, each about ½ acre in size, were sampled and then completely harvested. The error for the difference between estimated abundance and total catch varied from 0 to 7.6 percent.
