SECOND RECORD OF BLACK SKIPJACK, 



EUTHYNNUS LINEATUS, 



FROM THE HAWAIIAN ISLANDS 



Matsumoto and Kang (1967) reported the first 

 capture of the black skipiack, Euthynnus lineatus 

 Kishinouye, in the Hawaiian Islands. Recently 

 (14 July 1975), a second black skipjack was taken 

 in these waters by a Hawaiian pole-and-line skip- 

 jack tuna fishing vessel, the Mar/m, skippered by 

 Walter Asari. The fish was noticed by a fish re- 

 ceiver at Hawaiian Tuna Packers, Richard How- 

 ell, who contacted Robert T. B. Iversen, South- 

 west Region Representative stationed at the 

 Southwest Fisheries Center Honolulu Laboratory. 

 Iversen brought the fish to me for identification. 



The specimen, 454 mm fork length, and weigh- 

 ing 1.53 kg, was caught from a school of small 

 skipjack tuna, Katsuwonus pelamis, at the ex- 

 treme tip of Penguin Banks, about 40 km south of 

 the eastern end of Oahu. The specimen is de- 

 posited in the U.S. National Museum collection 

 (USNM 214683). 



Measurements in millimeters taken according 

 to the methods described by Grodsil and Byers 



(1944) are as follows: Fork length - 454; head 

 length - 126; 1st dorsal insertion - 144; 2d dorsal 

 insertion - 271; anal fin insertion - 306; ventral 

 fin insertion - 144; greatest body depth - 112; 

 greatest body width - 73; dorsal-ventral distance - 

 108; dorsal-anal distance - 188; ventral insertion 

 to vent - 160; length 1st dorsal base - 130; length 

 2d dorsal base - 29; length anal base - 25; length 

 pectoral - 70; height 1st dorsal - 61; height 2d 

 dorsal - 28; height anal - 28; diameter of iris - 19; 

 maxillary length - 50; snout to posterior margin 

 of eye - 54. 



Counts: 1st dorsal spines - 14, plus 1 imbedded; 

 2d dorsal rays - 12; dorsal finlets - 8; anal 

 rays - 12; anal finlets - 7; pectoral rays - 26; gill 

 rakers - left side 9 -H 1 -h 24 = 34, right side 9 + 

 1 + 25 = 35. 



The external characters agree with that of the 

 previous capture (Matsumoto and Kang 1967) 

 and with Godsil's (1954) description of the 

 species. Five black unbranched stripes run paral- 

 lel to the longitudinal axis of the body on the back 

 fi'om the corselet to the caudal fin, and five or six 

 faint unbranched stripes run horizontally on the 

 belly. Two black thoracic spots are located on each 

 side at the indentation of the corselet near the 

 ventral margin of the body. 



The vertebral count is 20 + 17 = 37. As in the 

 previous capture, four large protuberances are 

 present on the 31st vertebra, a characteristic of 

 this species (Godsil 1954). 



Although this is only the second specimen re- 

 corded, an interview with the skipper of the ves- 

 sel disclosed that fish similar to this are often 

 caught but are not reported. The question posed 

 in 1967 as to whether this is a chance migrant 

 from the eastern Pacific Ocean still stands.
