Collecting Event Remarks |
Water temp. = ? C. At each site, we set 6 1/8 inch mesh traps and 4 1/4 inch mesh traps. All traps set between 1600 and 1700 at sites B-E. We will set A later. Many large trout in lake. Local resident said lake level dropped recently, noting what he thought was illegal pumping for construction. Saw one loon and one grebe. Numerous stickleback at site A and in schools near bottom in 1 m of water. Station B: pulled at 1800 on 15 June. Only stickleack caught. Very abundant; filled 2 liter bottles with first 9 traps. Station E: pulled at 1815 hr on 15 June. Only stickleback caught. Not quite as abundant as at station E, but nearly 2 bottles filled. Reproductive males and females at both sites. Station D: pulled at 1833 on 15 June. 2 salmonids in traps. Otherwise only stickleback. They were so abundant that we filled 2 bottles with 6 traps and released the rest. Station C: pulled at 1855 hr on 15 June. Only stickleback; filled 2 bottles. Saw grebe eating stickleback. It came to surface, manipulated them and ate them head first. Stickleback fry in algae adhering to grass. Station A: set 4 1/4" mesh and 6 1/8" mesh traps on 20 June at boat ramp/public access at 1900. Pulled traps at 2030 hr on 21 June. Catch same as below.
