POMATOMID^. The Bluefishes. 



98. Pomatomus saltatrix (Linnaeus). Blue fish. 

 Geog. Dist.: Atlantic and Indian Oceans. 



Migrations: Its migrations are probably more influenced by the presence 

 of food than by temperature. They move along the coast from the south 

 toward the north in the spring, following schools of menhaden. Immense 

 schools appear off the Carolina coast in March and April; reaching the 

 Jersey coast in the early part of May; Newport, middle of May to first 

 week in June. In October they leave the northern coasts and appear olif 

 the coast of Carolina about the middle of November, where a very ex- 

 tensive fishery exists until late in December. Their presence off the 

 Carolina coast in autumn is preceded by schools of menhaden and marked 

 by flocks of birds. (Prof. Baird, Report U. S. Fish Commission, 1873.) 



Season in R. I.: Common but not abundant. They arrive about June 1, 

 and remain until the last of November. These fishes are 12 to 14 inches 

 in length. On August 27, 1905, many young of this species, 4 to 6 inches 

 long, were found gilled in the meshes of the traps. These had probably 

 been present for some time, but had before been too small to be held in 

 the nets. These increased to about 9 inches in length before the end of the
