Fish Surveys
2001 and 1954 fish surveys
The data shown in the file below, Data Summary of 2001 and 1954 Fish Surveys, is from the Department of Fisheries and Wildlife 2001 survey of the SuAsCo Watershed and from the Division of Fisheries and Game 1954 survey of the Merrimack and Ipswich Drainages. Note that this state agency is now called the Division of Fisheries and Wildlife, or MassWildlife.
The results are not directly comparable, because survey techniques have changed over the years and because the level of effort for each survey is difficult to compare. However some trends are noticeable in the summary below. For example: the number and percentage of chain pickerel, fallfish, and creek chubsuckers have decreased since 1954; smallmouth bass are no longer found but the number and percent of largemouth bass increased between 1954 and 2001; common carp were not reported in 1954 but are found in 2001.
