Data
summary of 2001 and 1954 Fish Surveys (Excel sheet)
The data shown here (click on the title above
for more detail) 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 Ispwich
Drainages.
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 noticable in the summary below. For example: the number
and percentage of chain pickerel, fall fish, and creek chubsuckers
have decreased since 1954; small mouth bass are no longer
found but the number and percent of large mouth bass increased
between 1954 and 2001; common carp where not reported in 1954
but are found in 2001.
