are not inconsistent with some of them remaining 

 in Area C into April or even May. 



Group D. — Seven of the 10 new returns in Group 

 D (white marlin tagged in Areas B and C, and recap- 

 tured in any area) (Figs. 1 and 4, Appendix Table 4) 

 were consistent with previous results, but three in- 

 dicated migratory tendencies which had not previ- 

 ously been noted. 



Two fish tagged off the northwestern Bahamas in 

 spring were recaptured off Virginia in September, 

 fitting well with our pattern for "'middle Atlantic" 

 white marlin. Another tagged in the same area in 

 late winter was recaptured in the western Gulf of 

 Mexico in June and one tagged in the northwestern 

 Gulf in July was recaptured off Havana in June. 

 Both of these support previous indications of sea- 

 sonal migrations between sojourns in the Gulf of 

 Mexico in the warm season and in the Straits of 

 Florida and off the northwestern Bahamas in the 

 cold season. There was also a local recapture in 

 August in the north central Gulf from a release 

 there at an unknown date, but in the warm season. 



There were three recaptures from releases in Au- 

 gust and September off Venezuela. One of these 

 was local in a subsequent August, and one was off 

 the Guianas in November, closely approximating 

 an August-December migration between these 

 areas which had been recorded previously. The 

 third differed somewhat in that it was recaptured 

 north of the release area in January. Evidently, this 

 fish had merely moved offshore into deeper water in 

 the fall, rather than migrating to the eastward as had 

 the ones recaptured in November and December 

 off the Guianas. 



The most surprising of the new Group D returns 

 was for a fish released off the northwestern 

 Bahamas in April and recaptured 600 miles ENE of 

 the mouth of the Amazon River in September. This 

 has no apparent resemblance to any of the migra- 

 tory tendencies indicated by other returns. This 

 migration of about 2,700 nautical miles is the 

 longest yet recorded for a white marlin, and is the 

 closest approach to the South Atlantic that has been 

 made by a white marlin tagged in the North Atlan- 

 tic. Ueyanagi et al. (1970) and Mather et al. (1972),
