Areas,such as coastal eastern Gulf of Maine(GOM),perceived to have low density of target fish species and having high density fixed gear,are often subject to low fishing pressure and not well *** can lead to a shortage of information regarding the fine scale dynamics of groundfish *** surveys are commonly developed for such areas with little monitoring and commercial fishing activity as a cost effective way to collect relevant data for monitoring the dynamics of fish *** this study,we outline an approach that utilizes information from other survey programs and pilot study for designing a survey that satisfies both the wish of fishermen participants to contribute their knowledge and experience in determining groundfish abundance and distribution and the statistical rigor required for stock *** an analysis of spatial and density distribution of groundfish populations based on data from pilot seasons of the sentinel survey and other monitoring programs,we designed a survey that has good spatial and temporal coverage and captures the spatial variability in species composition and size structure of key *** spatially explicit data collected in the program can contribute to a better understanding of groundfish stock status in the eastern *** approach,although developed for the coastal eastern GOM,is also applicable to other areas with similar issues.
