Harrington, R.W., Jr., and E.S. Harrington. 1961. Food selection among 

 fishes invading a high subtropical salt marsh: from onset of flooding 

 through the progress of a mosquito brood. Ecology 42:646-666. 



The study identifies larvivorous and non-larvivorous fishes that 

 frequent salt marshes and adjacent zones of the subtropical halosere 

 in Florida and measures types of food consumed by the fishes. 



An abrupt tidal -pluvial flooding allowed fishes in a high salt 

 marsh access to the whole marsh. Some 8,526 samples of 16 species 

 of fishes were collected. The stomach contents of 2,786 fish were 

 (by volume): 35.7 percent plant material, 23.8 percent Aedes_ mosqui- 

 toes, 14.6 percent copepods, 12.5 percent fishes, and 7.8 percent 

 shrimp. 



Interactive aspects of food selection among the fishes is discussed 

 with regard to the resources and vicissitudes of their environment, 

 competition for food, and breeding and spatial requirements. (B.W.)

Thomas J., P. Wagner, and H.C. Loesch. 1971. Studies on the fishes of 

 Barataria Bay, Louisiana, an estuarine community. Louisiana State 

 University, Coastal Studies Bulletin No. 6, Special Sea Grant Issue, 

 pp. 56-66. 



An extensive ecological study of two small areas in Barataria Bay 

 area began in March 1969. Seventy-five species of fish representing 

 65 genera and 40 families were collected with a shrimp trawl in Lake 

 Palourde and Airplane Lake in the southern area and John the Fool Bayou 

 in the northern area. After one year of qualitative studies, a quanti- 

 tative attempt to estimate fish biomass available to the trawl was 

 initiated in March 1970. The trawl was towed over a premarked distance 

 and the biomass of fish per area was calculated. Preliminary work on 

 stomach analysis of dominant fish, including croaker, spot, sea catfish, 

 bay whiff, and fringed flounder, has been started. Fish are being 

 classified into five general categories ranging from freshwater to truly 

 marine. Seasonality and growth of fish will be studied. (A. A.)
