Table 21.— Comparison of morphometric characters in populations of Sarda 

 sarda from North America, the Mediterranean Sea, and the Gulf of Guinea. 

 First set of numbers are measurements expressed as thousandths of fork 

 length, second set as thousandths of head length. 



Ocean, including the Gulf of Mexico and the 

 Mediterranean and Black seas (Figure 70). Its 

 usual northern limit in the western North Atlantic 

 is Cape Ann, Mass. (Bigelow and Schroeder 1953), 

 but there are records north to Casco Bay, Maine 

 (Nichols and Breder 1927) and to several localities 

 along the outer coast of Nova Scotia (from north to 

 south): Cape Breton Island (McKenzie 1939); 

 Halifax (Jones 1879); Lunenberg (McKenzie 1939); 

 Shag Harbour (Mather and Gibbs 1957); and Pub- 

 nico (Vladykov 1935). It is common along the east 

 coast of the United States but becomes uncommon 

 around Miami (D. P. de Sylva, pers. commun.) and 

 the Florida Keys (Schroeder 1924). Although Rivas 

 (1951) stated that there were no records of S. sarda 

 from the Gulf of Mexico or Caribbean Sea, there 

 are now several such reports; northern Gulf of 

 Mexico (Boschung 1966) off Pensacola, Fla. 

 (USNM 30692; CAS lU 7825), Dauphin Island, Ala. 

 and the Mississippi Delta (USNM 188420; UMML 



7745); Texas (Baughman 1941; Pew, 1954; Hil- 

 debrand 1955; USNM 118644-6; CAS SU 18003); the 

 middle of the Gulf (Klawe and Shimada 1959); and 

 Campeche, Mexico (Hildebrand 1955; Springer and 

 Bullis 1956). We have also examined a specimen 

 that was collected by Poey and labelled "Cuba" 

 (MCZ 17047). Sarda sarda is apparently absent 

 from most of the Caribbean Sea but is recorded 

 from Colombia (Dahl 1971) and Venezuela (Rohl 

 1942; Mago Leccia 1970), and we have examined a 

 series of specimens from the Gulf of Cariaco, 

 Venezuela, collected by the RV Geronimo in 1966. 

 Fowler (1915) stated that several were seen in the 

 fish market of Port-of-Spain, Trinidad but none 

 were preserved. Published records and museum 

 specimens become more common south of the 

 Amazon: Rio de Janeiro (BMNH 1903.6.9.77, 

 1923.7.30.303); Santos (Mirando Ribeiro 1918); Rio 

 Grande do Sul (Ihering 1897; MCZ 4739); Argen- 

 tina from lat. 35° to 38°S (Pozzi and Bordale 1935);
