METHODS 



From April 1965 to January 1968 we col- 

 lected samples each month in a Thalassia bed 

 adjacent to Bob Allen Key (fig. 2). These sam- 

 ples were taken with a sled-mounted suction 

 sampler (Allen and Hudson)^ and a slednet.^ 

 The suction sampler captures both epifauna 

 and infauna, whereas the slednet captures epi- 

 fauna only. These devices also were used to 

 sample in Thalassia beds on the east, south, 

 and northwest banks of the lake. To supple- 

 ment the catches made by the suction sampler 

 and slednet, we used a pushnet (Allen and 

 Inglis, 1958), beach seine, and castnet, to- 

 gether with hand collecting. 



A bait- shrimp vessel with two roller-frame 

 trawls (Woodburn, Eldred, Clark, Hutton, and 

 Ingle, 1957) was used to sample the lake's 

 biota at night. This method enabled us to in- 

 vestigate more thoroughly the large expanse 

 of lake bottom and capture nocturnal species. 



We used face mask and snorkel to examine 

 the channels. The organisnns were collected 

 by hand, handnet, and hook and line. 



Despite the variety of gear, we did not 

 collect many species known to inhabit the 

 lake. Also, we did not attempt to retain 

 plants and aninials less than 5 mm. long or 

 wide .
