I an considering conducting research on larval fish use/reproduction
of freshwater fish in coastal plain stream systems (South Carolina) by
comparing stream channel habitat usage to floodplain. My first
thought is to compare the number of individuals; number of individuals
of each species; and number of species from three stream systems using
stream channel and floodplain to represent the two conditions.
Variables I consider important to sample/collect include velocity,
D.O., temperature, and habitat characteristics (such as type of
aquatic vegetation and cover, type of substrate, % vegetation cover,
water depth, etc.). I plan on sampling fall through spring to
coincide with spawning events occurring during high water periods for
a two year period, sampling one or two times/week.
I would appreciate any ideas/comments. Specific questions include:
What type of larval fish sampling devise is appropriate for both
faster moving stream channels and slower moving floodplain waters?
Any ideas on adjusting the number of individuals collected since more
water (higher water velocity) will flow through the sampling
collection devises located in the stream channels? How long should
each collection last (24 hours?)?
I do plan on thoroughly researching this topic, but would appreciate
any early advise you may have.
