HAYNES; KING CRAB LARVAE IN THE BERING SEA 



each tow rather than use the average in my 

 analysis. The terms "positive tow" and "nega- 

 tive tow" are used to describe plankton tows that 

 contained king crab larvae and those that did not. 

 The station locations and developmental stages of 

 king crab larvae captured for the positive tows 

 are given in Table 1; the locations of both 

 positive and negative tows are indicated in the 



charts showing distribution of larvae (Figures 1 to 

 7). Charts showing distribution and abundance of 

 larvae were made by plotting the number of larvae 

 under 10 m^ of sea surface at each station and then 

 drawing isopleths. Identification of the larval 

 stages was based on descriptions given by Maru- 

 kawa ( 1933), Sato and Tanaka ( 1949), and Kurata 

 (1964).

 positive tow collected in the southeastern Bering Sea, 1969 and 1970.
