FISHERY BULLETIN: VOL. 74, NO. 3 



those 20-25 mm at 750-1,000 m, and those over 25 

 mm below 900 m. 



Of 41 specimens (21-31 mm) sexed, 24 were 

 females of which 6 (29-31 mm) were mature. The 

 17 males were 22-30 mm. Fish less than 16 mm 

 were taken only in July and September. There 

 were no seasonal trends in abundance of the larger 

 fish. 



Melatuphaes danae Ebeling (627; 1 1-22 mm) 



During the day, M. danac occurred principally at 

 750-1,200 m; a few were taken as shallow as 650 m. 

 Fish less than 15 mm were almost all taken above 

 1,000 m, while larger ones occurred throughout the 

 day depth range. Most night captures were 

 between 75 and 200 m; the small fish were mostly 

 taken at 75-100 m, while the larger ones occurred 

 throughout the depth range. There were no night 

 captures between 400 and 650 m, but 27 specimens 

 of all sizes were taken at night in tows that fished 

 within the day depth range. Although this catch 

 was numerically small, and possibly due to in 

 transit captures, it was large enough relative to 

 effort to suggest that a small, but not insignificant 

 fraction of the population did not regularly 

 migrate. 



Female M. danae matured at about 17-18 mm. 

 Mature females were present in comparable 

 numbers and percentages at ail seasons, but the 

 size composition of the catches indicated that 

 juveniles were recruited primarily in the spring 

 and early summer. For the series where the proper 

 depth ranges were adequately and roughly 

 equivalently sampled, the small (11-14 mm) fish 

 made up 27% of the total catch in March, 15% in 

 June, and 42% in July as opposed to 1% in Sep- 

 tember and 2.5% in December. 



Melamphaes sitnus Ebeling (4; 14-24 mm) 



Data on M. f^iinus indicate little more than that 

 it is present in low abundance in the area. The two 

 night captures were at 300 and 800 m, while the 

 two day captures were at ca. 700-800 m (the latter 

 depths are estimates from wire out; depth records 

 for both day tows were invalid). 



Melamphaes indicus Ebeling (20; 16-5 5 mm) 



Eleven M. indicus were taken at night at 

 125-150 m-nine of these in one tow. Nine 

 specimens were taken during the day at 640-900 m. 



Two large females (51 and 55 mm) were mature, 

 and four males (47-53 mm) appeared mature or 

 nearly so. 



Melamphaes sp. (janael Ebeling) (10; 17-54 mm) 



Seven M. "janae" were taken at night at 190-250 

 m and three during the day between 650 and 900 

 m. All were taken in September or November. The 

 two largest specimens (43 and 54 mm) were both 

 males and larger than the ma.ximum size of this 

 species given by Ebeling (1962). Ebeling, however, 

 did note geographic differences in size at maturity. 

 Our specimens fit the description of M. janae in 

 other respects and could be reliably distinguished 

 from similar-sized individuals of M. iyidicus. 

 Study of more specimens will be necessary to 

 determine whether M. janae is more variable in 

 size than Ebeling noted or more than one species is 

 involved. 



Melamphaes sp. {lotigh'elis? Parr) (2; 18, 20 mm) 



Two small specimens of the "typhlops" group 

 are tentatively identified as M. longivelis. The 

 smaller was taken at 625 m at night, the larger at 

 640 by day. 



Melamphaes po/ylep/s Eheling (10; 17-57 mm) 



One M. pohjiepis was taken at night at 930 m; 

 the remainder were taken during the day at 

 640-1,150 m. They included two mature females (56 

 and 57 mm), six males (46-56 mm), and two 

 juveniles (17 and 19 mm). 



Anoplogasteridae 



Auoplogaster cornuta (Valenciennes) 

 (93; 3-126 mm) 



Juvenile A. cornuta undertake a substantial 

 upward migration at night. At least some of the 

 large fish also move upwards, but occur deeper 

 than the juveniles both day and night. Seventy- 

 two specimens were small (3-24 mm) and were 

 taken in February-March. Fifty-eight were taken 

 at night between 135 and 185 m; the remaining 14 

 were taken during the day- 12 at 650 m and 2 at ca. 

 800 m. Larger specimens (all >70 mm) were taken 

 throughout the year. At night six (77-87 mm) were 

 taken between 275 and 475 m, one each at ca. 600 m 

 (108 mm), 900 m (109 mm), and in an oblique tow to 



640
