"In April, 1947, there were further 

 reports of fish mortality in the Gulf of 

 Mexico off the Florida Keys. . . . 



"... Off Key West (near Content Keys) 

 fish mortality was occurring in a situa- 

 tion in which the count of Gymnodinium 

 was 420,000 cells per liter. . . Further- 

 more, the mortality of fish and other 

 animals occurred sporadically over a 

 period of 9 nnonths from November, 



1946, to July, 1947. . . ." [p. 358,] 

 Gymnodinium brevis is described as 



a new species, with an illustration. The 

 chromatophores are described as 

 yellow- green in color in both living and 

 preserved specimens.

In early May 1948 the water of Middle 

 Lake, Dade County, was green and 

 opaque owing to the enormous abundance 

 of Gonyaulax , The water of certain areas 

 of Seven Palm Lake showed similar 

 patches. 



"Unpublished data in the possession 

 of the author show that during the 'red 

 tide' on the west coast of Florida, de- 

 scribed by Gunter et al. (op. cit.), 



Gymnodinium brevis amounted to 99.28 

 per cent and 98.99 per cent of the total 

 organisms in the water in two uncon- 

 centrated samples of sea water."

Plankton samples were collected dur-

 samples in June 1947) from 28 locali- 

 ties in the mangrove area of the Ever- 

 glades, between Everglades City and 

 Barnes Sound. Salinities are given on 

 dates of collection.

"One of our objectives is to deter- 

 mine whether the outflow of the Hills- 

 boro, Alafia, Little Manatee and Mana- 

 tee Rivers influences the phosphorus 

 content of Tampa, Bay and adjacent 



neritic waters The water of upper 



Tampa Bay (subarea 2) contained nnore 

 phosphorus than any of the rivers, ex- 

 cept the Alafia. These data indicate that 

 phosphorus may, on occasions, accumu- 

 late in this portion of Tampa Bay.
