FISHERY BULLETIN: VOL. 71. NO. 2 



Because young-of-the-year have not been cap- 

 tured at sea, biologists have presumed they 

 cannot survive there and, at an early stage of 

 development, must seek an estuarine habitat. 

 This presumption has been challenged, but not 

 systematically tested. 



THE CRUISE SCHEDULE 



Eight cruises were completed from December 

 1965 through December 1966. During each 

 cruise, we planned to sample at 92 stations 

 situated along 14 transects. Transects originated 

 as nearshore as water depths would allow the 

 RV Dolphin to enter, and extended seaward 

 to depths near or beyond the 183-m depth 

 contour (Figure 1). 



The sequence for sampling transects varied, 

 depending primarily on weather (Table 1). On 

 our first cruise in December, inclement weather 

 forced us to omit the two northernmost tran- 

 sects. We sampled at four additional stations 



Table 1. — Cruise schedule, sequence of sampling tran- 

 sects, and number of stations occupied during RV 

 Dolphin ichthyoplankton survey, 1965-66. Sampling inter- 

 ruptions in excess of 48 hr are shown, whether or not 

 the sampling sequence was affected.
