Subject: biological sampling in large river system
Dear Native Fish Enthusiast,
As part of a comprehensive in-river flow study on the Klamath River in
NW California, I need to initiate biological sampling on the Klamath
River mainstem. The Klamath is a large, turbid, and highly variable
river system. Basically, I need to find out exactly where fish live so
that a bioenergetic model can be combined with hydraulic data to help
create flow regimes that will enable recovery of the Klamath River's
The species I'm interested in sampling for (this means all lifestages
from fry to adult) include chinook salmon, coho salmon, steelhead,
Pacific lamprey, green sturgeon, eulachon, coastal cutthroat trout, and
possibly american shad.
As you can see, I'm interested in quite a large array of types, sizes,
times of year, etc, and any experience you've had, or anybody you know
of that's had this kind of sampling experience would be helpful to me.
I'm particularly interested in the techniques employed for large turbid
rivers such as the Missouri, Ohio, Mississippi, etc.
Bioacoustics? Gillnets? Electrofish? Radio tagging? All is in the
realm of possibility. What I'm really after is specific gear types and
connections. I need to know which manufacturer I should contact, person
I should call, etc. Simply responding "try gillnetting" won't do me
much good. I can tell you that I am already purchasing "standard"
fisheries sampling equipment such as an electroshocker, seines, exp.
gillnets, etc. What I'm after is more cutting edge (i.e. bioacoustics)
kind of stuff.
