This species is generally considered to be a ben- 

 thic inhabitant of moderately deep water. For 

 the first two records above, however, night tows of 

 the Cobb pelagic trawl at the surface (trawl fish- 

 ing no deeper than 24 m.) captured single speci- 

 mens of Torpedo about 24 km. (15 miles) offshore 

 in water about 350 to 690 m. deep.

Anchovies were taken at 33 stations. Nine of 

 these records were of larvae or small juveniles from 

 close inshore to about 260 km. (160 miles) off- 

 shore. Three stations produced records of an- 

 chovies that add significantly to our knowledge of 

 the biology of this species. (1) At station 89.90, 

 C6303, one adult was taken about 400 km. (250 

 miles) from nearest landfall. (2) At station 

 83.70, B6303, in the San Juan Seamount area — 

 where hake eggs were abundant in routine 

 oblique plankton tows (to about 140 m.), and 

 where freshly spent hake were caught in about 121 

 and 165 m. — anchovy eggs were abundant in a 

 near-surface plankton tow (about 5.5 m.), and 

 running ripe anchovies were caught in a midwater 

 trawl at about 81 m. The Cobb echo sounder 

 showed subsurface concentrations at 73 m. and 146 

 to 220 m. in this area. These concentrations prob- 

 ably represented anchovies spawning above a 

 deeper school of hake that was spawning or had 

 just finished spawning. (3) At station 93.29, 

 C6208, 13 km. (8 miles) off La Jolla over water 

 about 475 m. (260 fathoms) deep, the Cobb Simrad 

 registered a dense concentration at about 201 m. 

 (110 fathoms) (fig. 7) . With the aid of the depth 

 telemeter, the trawl was towed through this area. 

 The resulting catch was 200 kg. of anchovies. The 

 Simrad was monitored throughout the tow; and 

 the lack of other concentrations indicated that a 

 dense and unusually deep school of anchovies was 

 sampled. A bathythermograph (BT) cast at this 

 station showed a surface temperature of 68° F., a 

 thermocline at about 18 to 82 m., and a temperature 

 of 74° F. at 201m. 



ALEPOCEPHALIDAE

The specific identifications are questionable be- 

 cause of the small size of the specimens.
