In the last
twenty years, the Sacramento pike minnow, or squawfish,
has become a common sight in northern California's rivers.
Pike minnow are a species native to the Sacramento-San Joaquin
drainage, and were introduced into the Eel River system by sports
fishermen in 1979. Biologists worry that the predacious,
non-native pike minnow is having a detrimental effect on the already
low juvenile salmon populations in the Eel River system. In the
past, snorkel surveys have been conducted by California Department
of Fish and Game (DFG) to get a clearer picture of the pike minnow
population as well as to make connections between increased pike
minnow populations and decreased salmon populations. For
reasons unforeseen, DFG had to abruptly halt the surveys, and the
pike-minnow populations went unrecorded for some years.
Last July, ERWIG, with DFG head biologist Scott Downie's
assistance, organized a pike-minnow survey along various reaches in
the South fork Eel River. Members of the AmeriCorps Watershed
Stewards Project, fisheries biologists from DFG and interested
community members met bright and early to survey 40 pools on the
South Fork. A total of 6,483 pike minnow were counted ranging
in size from 4 to over 18 inches.
ERWIG is planning on conducting another survey this year,
and we need the community's help to make it happen. The exact
date has yet to be determined, but the month of July, with its sunny
skies and tolerable water temperatures, tends to be the optimal
choice. Volunteers will be rewarded for their hard work
(swimming in the river) with a barbecue hosted by our group.
