DAHLBERG: ECOLOGICAL STUDY OF GEORGIA COASTAL FISHES 



Figure 8. — Tidal "borrow pool" on west side of road to lighthouse on Sapelo Island. 

 Zonation of dominant plants along road bank generally from left to right in picture : 

 wax myrtle (Myrica cerifera) , groundsel-tree (Baccharus halimifolia) , marsh elder 

 {Iva frutescens), and sea ox-eye (Borrichia frutescens) . Juncus roemerianus and 

 Spartina alterniflora are dominant along the pool bank. There is an abundance of 

 crabs (Uca spp. and Sesarma sp.) in both the harder and softer substrates between 

 the pool and the road. 



stations 10 and 11) were sampled on RV Kit 

 Jones cruises, each station for 15 min with a 

 20-ft (6.1-m) otter trawl which had 114-inch 

 (32-mm) stretched mesh in the bag. Each of 

 the 14 trawl stations was sampled about 37 times 

 from January 1967 through December 1969 ex- 

 cept for stations 6, 8, 12, and 13, which were 

 sampled 33 or 34 times and then discontinued. 

 P'ive trawl samples were lost for various reasons 

 including snags at station 9 on two occasions. 



All Sapelo Island habitats (1, 7, 8, and 9) 

 were sampled during all four seasons and about 

 20 times from April 1967 through February 

 1970. 



Habitat 4 was sampled primarily with a 20-ft 

 (6.1-m) trawl and a 35-ft (10.7-m) seine. The 

 two trawl stations (10 and 11) are the upper- 

 most of the 14 stations sampled with the RV 

 Kit Jones from January 1967 through December 

 1969. Seining stations were sand bars that were 



exposed only near low tide. Regular stations 

 were at the lower end of Carrs Neck Creek (mile 

 point 10 = 16.1 km) and the mouth of Payne 

 Creek (mile point 15.4 = 24.8 km). These sta- 

 tions were seined approximately monthly from 

 June 1969 to May 1970. In addition 22 collec- 

 tions were made between the upper end of Carrs 

 Neck Creek and mouth of Riceboro Creek with 

 the seine, a cast net, and a 10-ft (3.05-m) trawl 

 towed by an outboard motor boat. 



In habitat 5 most fish collections were seined 

 at low tide at a muddy sand bar (station G) be- 

 tween the Seaboard Railroad tracks and the 

 effluent outfall of the Interstate Paper Corp. 

 Trawling (10-ft trawl) was most fruitful in the 

 winter. Seine and dip-net collections were made 

 at the Crossroads station. 



A few additional collections were made with 

 a 100-ft (30.5-m) seine in habitat 1, by angling 

 in habitats 1 and 2 (Dahlberg and Heard, 1969),
