520 |a"A new technique in scallop data analysis is presented both to improve sampling design in research surveys and to facilitate determination of exploitable scallop biomass. Commercial Canadian fishing logs record daily effort, catch and navigational bearings for locations fished, thereby permitting a high degree of resolution in the analysis of pattern of scallop distribution. Techniques have been developed to permit isopleth mapping of commercial catch, effort and CPUE, and an evaluation of parameters to achieve maximum realism is presented. In particular, degree of data spreading and calendar duration of fishing activity are discussed. Analysis of commercial log records from the first six months of 1978 are compared with observations from a 'ground truthing' research cruise, and general support was indicated for the role of isopleth plotting of research and commercial fishery data as a descriptive stock assessment tool"--Abstract.
