record for spotfin mojarra, Eucinofitomus argen- 

 teus, known to us was reported by Bailey et al. 

 (1954) from the Escambia River. A leptocephalus 

 of tarpon, Megalops atlantica, from East Bay 

 represents the second and most northern record 

 of a larval tarpon in the Gulf of Mexico (Tagatz, 

 1973). 



The following is a taxonomic list of all fishes 

 collected, 84 species representing 46 families. 

 Forty-four species were obtained from the Pensa- 

 cola Bay bridge and 75 from the East Bay-East 

 Bay River area with 35 of these common to both 

 areas. The number and length of each species 

 by month are listed for the areas from which it 

 was captured: Bridge (Pensacola Bay bridge). 

 Bay (upper 4 miles or 6.4 km of East Bay) and 

 River (lower 5 miles or 8.0 km East Bay River). 

 Also given are the salinity and temperature 

 ranges at the time of collection. The low value of 

 each range is based on the lowest combination 

 of surface and bottom readings (presented in the 

 order, surface/bottom) taken at any one time; the 

 high value, on the highest combination. Salinity 

 is in parts per thousand, water temperature in 

 degrees C, and total length in millimeters.
