Survey design for detecting patches

M.D. Nicholson and J. Barry

In this paper, we are concerned with designing surveys for detectingpatches of some exploitable resource, such as a shellfish stock. We take as our objectivethat, if there is one or more circular patches above some specified size, then theprobability of detecting at least one patch should be high. We show how the requiredsampling intensity can be modified in the light of information about the likely number andsize of patches. The results are applied to two surveys for detecting exploitable patchesof cockles (Cerastoderma edule).
