FISHERY BULLETIN: VOL. 81, NO. 4 



conducted by the Northeast Fisheries Center's RV 

 Albatross IV on southeastern Georges Bank during 

 spring 1981 (14 April- 1 May-Uune). Sample dates and 

 station location where larvae were selected for otolith 

 analysis are shown in Figure 1 and Table 1. The sam- 

 ples were collected with either 1) a continuous 

 double-oblique haul 3 using a 61 cm bongo net sam- 

 pler (0.505 and 0.333 mm mesh) deployed to a max- 

 imum depth of 100 m, or 2) a MOCNE SS 4 fitted with 

 0.333 mm mesh nets which sampled discrete vertical

layers from the bottom of the water column to the sur- 

 face. Stations with high densities of cod and haddock 

 larvae in good condition were selected during the 

 cruises for a study of larval otoliths. Larvae were 

 removed immediately following the haul and pre- 

 served in 95% ethanoL Temperature data for each 

 station were obtained from surface bucket readings, 

 expendable bathythermograph traces, or MOC- 

 NE SS profiles. 



In the laboratory, larvae selected for analysis were 

 representative of the entire size- range collected. The 

 standard length, as well as several other morphomet- 

 ric measurements, of each larva was measured to the 

 nearest 0. 1 mm prior to removal of their otoliths. The
