THE AYU OR SWEETFISH FAMILY 



20 Family Plecoglossidae 

 The single member of this family is often placed in the family with 

 the salmon and trout. This fish resembles a small trout in form and like 

 them runs up fresh water streams. 



Ayu or Sweetfish . . 



20-1 Plecoglossus altivelis Temminck & Schlegel 



The sweetfish, as its name implies, is one of the finest of food fishes. 

 It reaches a foot in length and is found in Japan, Hokkaido, Formosa, and 

 Korea. 



The eggs of this fish were introduced into Kalihi pool on Oahu by 

 Dr. Chiyometsu Ishikawa during the 1920's. Since the fishes have not been 

 reported since their introduction, it is probably safe to assume that they 

 did not survive. 



THE STOMIID FISH FAMILY 



21 Family Stomiidae (Stomiatidae) 



The fishes which make up this strange family are all found in deep 

 water. Like many other deep sea fishes, they have voracious habits, large 

 mouths with fang-like teeth, and large eyes which are directed forward. 

 Their bodies are long and tapering. 



Two species of this family are known from Hawaiian waters. 



Stomiid Fish 



21-1 Stomias boa (Risso) 

 This deep sea fish is called bathypelagic — meaning that it is a free 

 moving species living at considerable depths. It is found in both the 

 Atlantic and Pacific Oceans. It will reach a length of twelve inches.
