The golden shad, or skipjack, is a beautiful, symmetrical 

 fish, shading from green to silvery, with rich golden reflections. 

 It ranges along the Gulf coast from Pensacola on the east to 

 Galveston on the south and west, and up the Mississippi and 

 Ohio rivers to Pittsburg and the larger streams of Kansas. 

 It is not a common fish in Illinois, and occurs but seven times 

 in our collections, all from Mississippi. Rock, and Illinois River 

 localities. It appears at Alton in small numbers in September, 

 two pounds being about the maximum weight. It is an active 

 fish, frequently leaping from the water in sport or in pursuit of 

 its prey whence its name of skipjack. It is a predaceous 

 species, the young feeding on insects, and the adults on other 

 fishes.
