 vation of the other fish ; they were more successful in the act of

 found apparently an abundant food supply on the vegetable 

 growth and also on this green slime, and they did quite well. 

 The green slime and the vegetable growth also furnish a hiding- 

 place for the young, so that the older ones cannot pursue and 

 attack them. 



There was one statement Mr. Lane made I didn't under- 

 stand. He spoke of the fish eating this slime. I would like to ask 

 whether they eat the slime, or merely the animal growth that 

 lives on that slime? 



Mr. Lane : It may be the animal growth, but the slime dis- 

 appeared.
