Marine fish and invertebrate atlas : geographic distribution, population indices and environmental associations of marine species in the Scotian Shelf and Bay of Fundy derived from the annual Maritimes...: Fs97-6/3498E-PDF
"The summer research vessel survey on the Scotian Shelf bioregion started in 1970 and was designed to measure the distribution and abundance of major commercial and non-commercial species. This report builds on previous work and former atlases by updating a comprehensive suite of indices to assess population status and environmental associations of 103 species. For each species, trends in geographic distribution and biomass were plotted. The spatial extent of distribution was plotted over time to gauge changes in the area occupied. The relationship between abundance or biomass and spatial extent reflected whether the species distribution expands when biomass increases. Length frequencies over time depicted any changes in mean size. The plots of condition over time revealed whether individual fish are fatter or thinner than their long term mean. Depth, temperature and salinity associations were estimated to gauge the range of suitable environmental parameters for each species. Finally, for each stratum, the slope describing how local density varies with regional abundance was estimated. The reproducible set of tools provided in this report constitutes a stepping stone to conduct other ecological analyses using the summer groundfish research vessel survey data by fostering reproducibility and transparency of ecological information collected and reported annually"--Abstract, page vii.
