Krieger and Ito: Distribution and abundance of Sebastes borealis and 5. aleutianus 



267 



Of the 531 rockfish on the bottom, only 21 moved 

 when passed or approached by the submersible; 5 

 moved 0.5-1.0 m above the seafloor and swam less 

 than 5 m away at a speed of less than 1 km/h, and 16 



moved less than 2 m along the seafloor by drifting or 

 by slight movements of fins. The submersible drifted 

 against several large rockfish, which did not respond 

 as they were pushed along the seafloor.
