A stepwise linear discriminant analysis was used to in- 

 vestigate the population structure of summer flounder 

 based on 18 morphometric and meristic variables. Two 

 populations were identified: one in the Middle Atlan- 

 tic Bight, or between New York and Cape Hatteras, 

 N.C.; the other in the South Atlantic Bight, or be- 

 tween Cape Hatteras and Florida. 



Metamorphosing young of summer flounder were col- 

 lected from surface waters at all stations within the 

 Neuse River complex. Recruitment into the river 

 system occurred from January to April. Monthly 

 length distributions of larvae and young are pro- 

 vided.

 Carolina estuaries: assessment of environmental factors 

 and sampling success among Bothid flounders and 

 Penaeid shrimps. Chesapeake Sci. 9:27-41. 



The effects of salinity, temperature, current velocity, 

 wind direction, mechanical clogging of nets, and lunar 

 phase on sampling of postlarval flounders, including 

 summer flounder, are discussed.

 Chesapeake Sci. 9:109-120. 



A comparative skeletal study was made of the young 

 (10-130 mm) of three closely related species of 

 flounders — Paralichthys dentatus, Paralichthys 

 lethostigma, and Paralichthys albigutta. Osteological- 

 ly, vertebral and pterygiophore numbers produced the 

 best separation with P. dentatus having the highest 

 counts. Total gill rakers on the first gill arch and lateral 

 line scales were useful characters with the highest 

 numbers again appearing in P. dentatus.
