Bee + Moth in Water. Also,
Large (6-7") Scorpion.
Temp.
AIR - 19.5°C
Water - 33.5°C
Planaria active.
Scum dense → good population (75) of fish
on shelf until we put the 4 x 4' bag seine
in and the scum shifted. Then, the
scum dispersed over the entire surface of
the water & the fish had to be dipnetted
one by one - only 2-4 fish at a time
in the seine (small juveniles + large
adults only). Activity then very low
even though we got completely out of
the water for 30-45 minutes.
0910 hrs - Light
12.2 incidence.
