Figure 13. — Distribution of larvae of the gempylid, Genipylus serpens Cuvier and Valenciennes, and of the 

 cynoglossid flatfish, Symphunis spp., on EASTROPAC I. Records of occurrence of larvae of G. serpens are 

 shown as large circles with dot in center, Symphnriis spp. as open squares for hauls containing 1 to 25 larvae 

 and solid squares for hauls with 26 or more larvae; negative hauls are shown as small solid circles. 



29- SCOMBRIDAE 

 ( 185 occurrences, 1,919 larvae) 



Larvae of scombrid fishes ranked fifth in 

 abundance, and made up over 2 % of the larvae. 

 Larvae of the bullet mackerel, Aiixis spp., (161 

 occurrences, 1,563 larvae) were by far the most 

 abundant and widely distributed. Larvae of 

 skipjack tuna, Katmivotuis pelamis (Linnaeus) 

 (17 occurrences, 214 larvae) were taken mostly 

 in the offshore southern portion of the EAS- 

 TROPAC area. Other scombrid larvae included 

 yellowfin tuna, Thnnnus albacares (Bonnaterre) 



(19 occurrences, 40 larvae) ; bigeye tuna, Thun- 

 nus obes7is Lowe (1 occurrence, 1 larva); black 

 skipjack, Euthynnus lineatus Kishinouye (2 oc- 

 currences, 77 larvae); regular Scomber sp. (2 

 occurrences, 7 larvae) ; Spanish mackerel, 

 ScomberomonLS sp. (2 occurrences, 3 larvae); 

 and the wahoo, Acanthocybium solandri (Cu- 

 vier) (1 occurrence, 1 larva). The tuna larvae 

 have been turned over to W. Klawe of the Inter- 

 American Tropical Tuna Commission for de- 

 tailed study. He kindly has given me permission 

 to include data on occurrence and abundance of 

 larvae of skipjack and bullet mackerel in Ap-
