3.3 Sex Ratio The ratio of adult females to males is given in Table 2 .The years 1995-97 showed a slightly male biased sex ratio (P
Average Depth of Individual = x 1 z 1 + x 2 z 2 + ….+ x n z n (10) x 1 + x 2 + …x n where z 1 is depth 1 and z 2 is depth 2, x 1 is the number of individuals at depth 1, x 2 is the number of individuals at depth 2 and so on to depth n (Wetzel 1991). Table 3 gives the average depth distributions for the spring 24 hour survey: Table 3: Average depth distribution of E. drieschi life stages, Station F, Spring survey, April 1997 ---------------------------------------------------------------------------------------------------------- Day Mean Depth Distribution (m) ----------------------------------------------------------------------------------------------- Adults 13.48 Juveniles 8.26 Nauplii 9.62 -------------------------------------------------------------------------------------------------------- Night Mean Depth Distribution (m) -------------------------------------------------------------------------------------------------- Adults 7.50 Juveniles 5.72 Nauplii 8.76 ---------------------------------------------------------------------------------------------------------- Spring temperature profiles showed an average temperature difference of 3 0 C from surface to bottom. The lake is mixed with no distinct thermocline. Chlorophyll concentrations (g/l Chl) show maximums during full daylight in the upper depths. Nanoplankton (20 m) plankton in the water column. Oxygen profiles are typical for the season. Average Secchi depth was 2.42 meters, and visible light diminished below 5 meters depth.
