A sequential sampling plan for hard clams in lower Chesapeake Bay

Sequential sampling: A cost-effective approach for monitoring benthic macroinvertebrates in environmental impact assessments

“…Sequential sampling has been used in estimating population densities of marine molluscs (for example, see the work of Saila andothers 1965, andLoesch 1974), and it is frequently used for monitoring terrestrial insect pests (see bibliography by Pieters 1978). This survey revealed that the average time required to take samples in the field was less than 5 percent of the total sorting and identification time in the laboratory.…”

Effects of beach replenishment on the nearshore sand fauna at Imperial Beach, California

“…A special sampling program would have to be designed to obtain good estimates. Populations of large, relatively low density species cannot be estimated unless extensive dredging is employed to obtain large samples (see Loesch, 1974).…”
