FISHERY BULLETIN: VOL. 70, NO. 2 



The occurrence of the threadfin shad at Sapelo 

 Island may have resulted from recent introduc- 

 tion of this species in the Altamaha and Savan- 

 nah River drainages by the Georgia Game and 

 Fish Commission. Movement to the north 

 through estuarine waters is also possible. This 

 species was taken in water as saline as 29.8%o 

 and over a temperature range of 26.0° to 30.6°C. 



The scaled sardine (Harengula pensacolae) 

 and Atlantic thread herring (Opisthonema oglin- 

 um) were occasionally collected in the higher 

 salinity waters of the beach, lower reach, and 

 high marsh habitats. The Spanish sardine 

 (Sardinellu anchovia) was reported from St. 

 Simons Beach by Miller and Jorgenson (1969). 



Engraulidae - anchovies 



Of four species of anchovies known from 

 Georgia, only the striped anchovy (Anchoa hep- 

 setus) and bay anchovy (A. mitchilli) were 

 common and widely distributed in the estuary. 

 The bay anchovy was one of the most abundant 

 fish species in trawl and seine collections. It 

 was often collected in fresh waters of the oligo- 

 haline creek and upper and middle reaches, but 

 was absent from protected waters with low sa- 

 linity. The bay anchovy was present through- 

 out the year at a temperature range of 7.9° to 

 32.0°C. The striped anchovy was found in few- 

 er habitats than the bay anchovy, and it occurred 

 only during warmer seasons, May to November, 

 at a temperature range of 15.7° to 30.8°C. 



Two tropical species {A. cubana and A. lyole- 

 pis) were collected at St. Simons Beach (Miller 

 and Jorgenson, 1969) but were not collected at 

 Sapelo Beach. 



ORDER SALMONIFORMES 



Esocidae - pikes 



The pickerel (Esox americanus) was collected 

 at five freshwater stations. On 16 December 

 1969, one specimen was trawled in lower Rice- 

 boro Creek where the salinity was O.S%c and the 

 temperature, 7.4 °C. 



Umbridae - mudminnows 



The little-known eastern mudminnow {Umbra 



pygmaea) was collected at freshwater station 6, 

 the Ogeechee River tributary. This Coastal 

 Plain species is rare in collections from Georgia 

 waters. 



ORDER MYCTOPHIFORMES 



Synodontidae - lizardfishes 



Only one species (Synodus foetens) of the 

 lizardfishes ranges inshore in Georgia estuaries. 

 Six specimens were collected by trawls in 1967 

 and one by a seine in 1969 in the lower and mid- 

 dle reaches from June to November when the 

 salinity was 16.7 to 32.0;^c and temperature was 

 16.3° to 31.5°C. 



ORDER CYPRINIFORMES 



Cyprinidae - minnows and carps 



Three species of the freshwater cyprinids 

 were collected. Some large carp {Cypyinus 

 carpio) were caught in the lower Atlamaha Riv- 

 er during the spring and some apparently moved 

 to Doboy Sound and off Sapelo Beach with the 

 flood waters that reduced salinities to 6.8%f along 

 Sapelo Beach. Three large carp were found 

 dead on Sapelo Beach in April 1970. Some sur- 

 vived in a low-salinity tidal creek that was tem- 

 porarily dammed on Sapelo Island until June 

 when they were found dead. The alien carp is 

 not known from the North Newport River head- 

 waters. 



The golden shiner {Notemigonus crysoleucas) 

 was common in the freshwater habitat, and 

 three juveniles (20-24 mm) were collected in the 

 oligohaline creek on 4 September 1969 when the 

 salinity was 0%o and temperature was 26.4°C. 

 The golden shiner is a common bait and forage 

 fish in Georgia. 



The little-known taillight shiner (Notropis 

 maculatus) was taken only at freshwater sta- 

 tion 4. 



Catostcmidae - suckers 



The lake chubsucker (Erimyzon sucetta) was 

 collected at freshwater stations 1, 4, and 6.
