Initial Observations:
Weather - clear
General Condition - Algae abundant. Floating algae at S. edge of upper shelf.
Saum present until disturbed - shift even when not disturbed.
Activity - 7/100 on upper shelf at 0900 hrs.
Many at surface - incl. both small adults and young. Larger adults stay mostly at bottom around rocks.
Young observed frequenting shallow southern edge of upper shelf.
Again - slight schooling. No territoriality.
Some breeding activity (but very little)
Planaria around floating algae. Also seen swimming in mid water (surface) + around rocks in deeper portion of upper shelf.
Collection -
Bait not effective
Trapping: This time we decided to see if bait made any difference in number captured per trap, so two traps were set - about 1½' away from each other - in each instance, one baited, one not. Floater + sinkers
