GENUS ARCHOPLITES GILL 



This genus contains a single species, the Sacramento perch, 

 A. interruptus, the only species of the family found on our 

 Pacific Coast. 



It inhabits the Sacramento and the San Joaquin rivers, and their 

 tributary streams and lakes, and has been abundant throughout 

 its range. It is said, however, probably without reason, that it is 

 being exterminated by the carp and catfish, which infest its 

 spawning grounds. This species reaches a length of i to 2 feet, 

 and is regarded as an excellent food-fish. We know nothing 

 as to its game qualities. 



Colour, blackish above, side silvery, with about 7 vertica^ 

 blackish bars, irregular in form and position, and more or less 

 interrupted; body sometimes almost wholly black, sometimes 

 brassy; a black opercular spot; fins nearly plain.
