Kilby, J.D. 1955. The fishes of two Gulf coastal marsh areas of Florida. 

 Tulane Studies in Zoology 2:175-247. 



A study was made of the fish fauna of two coastal marshes on the 

 Gulf coast of Florida to determine, primarily, the composition of 

 those fauna and to discover, if possible, the more obvious ecological 

 factors which were shaping them. 



The two areas chosen for study were different ecologically. The 

 one at Bayport had less saline waters and more stable temperatures 

 than the one at Cedar Key. The areas were also quite different with 

 regard to physical and faunal features. 



Seventy-five species were recorded during the study and species 

 data are presented in an annotated list. This treatment is supplemented 

 by tables, graphs, and other compilations designed to present certain 

 of the data that could be summarized. 



The cyprinodontids were the dominant family of fishes in the brackish 

 waters studied. Despite the relative importance of the factors of 

 salinity and the availability of species, it was noted that the fishes 

 which occur in greatest abundance in the brackish marshes at both 

 Cedar Key and Bayport belong to freshwater groups. 



The author concluded that the intertidal marshes at both areas 

 were populated principally by fishes with freshwater, rather than 

 marine, affinities. (Author's summary and B.W.)

physical dynamics of a Georgia tidal creek. Chesapeake Science 17:271-280. 



Little is known about the interrelationship between marshes and tidal 

 creek communities. Tidal creeks are integrally associated with the 

 salt marshes, since most of the material moving in or out of these areas 

 must pass through tidal creeks. Sixty-five percent of the nation's 

 commercial fish, shellfish and marine sportfish spend all or part of 

 their lives in estuaries. Secondary productivity of estuaries manifested 

 in the productive fisheries is dependent on the productivity of tidal 

 marshes. Tidal creeks may transport the food that nourishes these 

 animals. 



This study deals with the species composition, population dynamics, 

 and seasonal distribution of the nekton and epifauna inhabiting a 

 tidal creek in Georgia. Five stations in and near the tidal creek
