ALP 3

Contents
where,
Lp = the number of specimens (fish and embryos) alive immediately after passing through the
sleeve valve
and
Tp = the total number of live specimens (fish and embryos) passed through the sleeve valve
Once the values of PI are calculated for every trial and for each species and reservoir elevation,
we will conduct a z -test for each set of trials to determine if they are different from zero (0).
For H2A, the proportion of live fish and embryos is deteratitied for each test group 4 days (96
hrs) after sleeve valve passage. The proportion of ft ;sample still alive 4 days after sleeve valve
passage is called 96 hr survival and is determined by the number of specimens still alive 4 days
after sleeve valve passage divided by the number of live specimens inserted (PA):
For reservoir elevation 6805, neither of the FHM (50 mm), BG (33 mm), or RBT egg data sets
was statistically equal to zero at 0 hrs or at 96 hrs after sleeve valve passage.
For reservoir elevation 6828, the FHM (55 mm), LMB (70 mm), or RBT egg data sets were not
statistically equal to zero at 0 hrs after sleeve valve passage. The FHM (55 mm) and LMB (70
mm) data sets was statistically equal to zero at 96 hrs after sleeve valve passage however, the
RBT egg data was not statistically equal to zero at 96 hrs.
