Collecting Event Remarks |
Water temp. = 18 C. A. set at 1935 hr on 10 June. 5 traps to right and 5 to left of boat ramp. They are pumping water here now, creating turbidity. A site traps pulled at 2000 hr on 12 June. Temperature 22°C now at boat ramp. DNA/brain sample: 10 traps set at 2045 hr on June 12. Water level obviously low here. 5 traps to left, 2 in front, 3 to right. Traps pulled at 2130 hr on June 13. Many stickleback, mostly 1+. A random sample of 100 specimens and a sample of complete morphs (85) collected and put on ice. Site B Gravel Pit: 10 traps set at 1900 hr on 13 June. School of 15 cm SL trout in area (about 25). Loon in middle of lake. Depth to 1 m. Traps pulled 1330 hr on 14 June. Site C Outlet: set 20 m east from outlet because of low water. 10 traps set at 1920 hr. Depth to 25 cm. Traps pulled 1350 hr on 14 June. Site D Lilly edge: there is a 4 m gap between recumbent tree limbs and the lily patch offshore. Dept to 35 cm. 10 traps set at 1950 hr. Traps pulled 1430 hr on 14 June. Site E near road: 10 traps set at 2005 hr. Depth to about 1 m. Traps pulled 1450 hr on 14 June. Every station produced 2 liters of sample and we threw a few hundred stickleback back at all but station A. It may be that larger stickleback were more common in deeper water. We released one Catostomus. We saw a loon feeding and a merganser on the lake. |
