the market in fish traps; also taken in the 

 seine. The young are often observed swim- 

 ming under jellyfish. A young specimen 

 taken with the dredge at Fish Hawk station

Food: Fish. Smaller specimens were found by 

 Dr. Linton to contain copepods, annelids, and 

 small fish, and in September principally 

 amphipods. 



Parasites : (Linton) Acanthocephala Echino- 

 rhynchus acus, E. sagittifer. Nematodes 

 Heterakis sp., Ichthyonema sp., Lecanocephalus 

 annulatus, immature nematodes. Cestodes

 (cysts), Rhynchobothrium bulbifer (cysts), R. 

 longispine (cysts), Scolex polymorphus (larva?),

The attractiveness of this delicately flavored fish 

 for the table is frequently diminished by the 

 presence of abundant cestode cysts throughout 

 its muscles.
