are fish taxa (331), followed by crustaceans (111) 

 and mollusks (74). Prey organisms are listed al- 

 phabetically, according to the tuna species. The 

 food consumed by the species of tuna was generally 

 similar. Differences in food between the juvenile 

 and adult bluefin tuna were pronounced; juveniles 

 fed largely on crustaceans whereas adults fed pri- 

 marily on fishes. Seasonal differences were noted 

 in the composition of the food of skipjack and yel- 

 lowfin tunas in African waters.

 ABSTRACT 

 The fishery for northern lobsters, Homarus amer- 

 icanus, in the offshore waters of the North Atlantic 

 is developing rapidly and is expected to alter certain 

 lobsters have been taken during research cruises 

 and from commercial catches to document the ex- 

 isting size composition, sex ratio, and size at ma- 

 turity. These records will provide useful indices 

 of population changes as fishing effort increases. 

 The data in this report are from five of the major 

 fishing areas — Hudson, Veatch, Oceanographer, 

 Lydonia, and Corsair Canyons. Lobsters from can- 

 yons 200 km. from shore were substantially smaller 

 than those from areas farther offshore. The size 

 of lobsters generally increased with depth and the 

 proportion of females generally increased with in- 

 creasing size. Females dominated the samples and 

 sometimes were 70 percent of the catch. The num- 

 bers of egg-bearing females are reported. The 

 smallest female with external eggs was 8.0 cm. in 

 carapace length.
