and largest during the first half of March, In 

 both years the catches were similar. The av- 

 erage for the March peak was 0.18 per m* in 1968 

 and 0.14 per m^ in 1970 and for the period be- 

 tween February and April, 0.08 per m^ in 1968 

 and 0.09 per m^ in 1970. The larvae were abun- 

 dant longer in 1968 than in 1970; the large 

 catches in 1968 extended into April and May. 



In spring the numbers of larvae in the catch 

 declined sharply with the end of the larval stage 

 of the dominant species and continued gradually 

 to decline to a low point in July and August. 

 Most of the remaining larvae were taken in the 

 spring and summer and, although fewer in num- 

 bers, more species were present. Species in this 

 group were: Aspidophoroides monopterygius, 

 Merluccius bilinearis, Ammodytes americanus, 

 Sehastes marinus, Cyclopterus lumpiLS, Limanda 

 ferruginea, Osmerus mordax, Syngnathus fus- 

 cus, Scophthalmus aquosus, Ulvaria suhbifur- 

 cata, Enchelyopus cimbrius, Tautogolabrus ad- 

 spersvs. Of these, U. subbifurcata and E. cim- 

 brius were obtained as larvae into the fall. 

 Clupea harengus harengus hatched in September 

 and October and was present in the area as larvae 

 through May. The increased larval abundance in 

 September and October was due to the hatching
