were impressed by the fact that they were very few to almost no very small fish as they have been in the past. They seined with the 4' x 1/8" mesh seine and dipped with the 4" aquarium dip net. They also collected some planarians which we carried around in 15 gals. of water all day - they died probably after the water temp. reached 37°C. After all planarians were death Jim Tener noticed a yolk sac fry C. diabolus still alive in the water. We had not previously known that it had been collected - probably when the water was dipped out of Devil's Hole. It does show that reproduction has occurred since we removed most of the fish on 1 July.
