to southwest Alaska; Aron 4 for southern Califor- 

 nia to southwest Alaska; Pearcy 5 for Oregon; 

 Porter (1964) for northern California (flatfish 

 only); LeBrasseur 6,7 for the northeast Pacific; Day 

 (1971) for Washington to British Columbia]. Two 

 additional reports (Aron 1959; LeBrasseur 8 ) 

 briefly mentioned larval fishes in the text. 



More recent reports have been based on surveys 

 designed specifically to sample ichthyoplankton 

 using meter nets and bongo nets [Waldron (1972) 

 off Oregon, Washington, and British Columbia in 

 April-May 1967; Richardson (1973) off Oregon 

 from May to October 1969; Naplin et al. 9 off 

 Washington and British Columbia in October- 

 November 1971; Dunn and Naplin 10 off Alaska in 

 April-May 1972; Pearcy and Myers (1974) off 

 Yaquina Bay from June 1969 to June 1970]. 

 Results were quantitative and more refined 

 species lists were provided. However most of these 

 studies were restricted in seasonal coverage to 

 periods of less than 1 yr. Pearcy and Myers (1974) 

 presented a year-long data set but listed only 

 yearly mean abundances. Discussion of larval 

 distribution patterns in all these papers was 

 limited. Waldron (1972) arbitrarily divided his 

 data into two groups located inshore or offshore of 

 the 914-m contour and discussed larval abun- 

 dances in each region. Pearcy and Myers (1974) 

 discussed horizontal variations in larval dis- 

 tributions with respect to larvae that occurred 

 offshore and those that occurred in Yaquina Bay. 

 Vertical distribution and day-night differences 

 have not been discussed, although Richardson 

 (1973) compared deep (to 200 m) and shallow 

 (upper 20 m) tows.

MATERIALS AND METHODS 



Most data came from samples taken at 12 

 stations, located 2 to 111 km offshore along an 

 east-west transect (lat. 44°39.1'N) off Newport, 

 Oreg., just north of Yaquina Bay (Figure 1). The 

 transect extended over the continental shelf and 

 slope; depths ranged from 20 to 2,850 m. Samples 

 were taken every month from January 1971 to 

 August 1972 except in January and February 

 1972, although not every station was sampled
