representing 49 taxa (genera or species) 

 in 27 families; 90,402 (957^ of the to- 

 tal) were northern anchovy, Engraulis 

 mordax (Table 1 ). Anchovy larvae were 

 more than 40 times as abundant as the 

 next most abundant species, California 

 smoothtongue iLeuroglossus stilhius). 

 White croaker (Genyonetnus lineatus) 

 ranked third, and the northern lamp- 

 fish iStenobrochius leucopsarus) 

 ranked fourth, followed by the rockfish 

 genus Sebastes. These five taxa consti- 

 tuted 99'7r of the total larvae. Follow- 

 ing in abundance were queenfish iSer- 

 iphus politus). Pacific pompano (Pep- 

 riltis simillinms), California halibut 

 (Paralichthys californicus), the sand- 

 dab genus Citharichthys, and Pacific 

 _hake (Merluccius productits) (Table 1). 



Most of the larvae captured in the MESSHAI nets 

 were at yolksac and preflexion stages. Relatively
