LIFE HISTORY

Physical description: The dorsal fin rays number 17-22, anal fin rays 20-25, caudal fin rays 9 + 10 + 9 + 6-7, pectoral fin rays 15-19, and pelvic fin rays 8-9. The scale rows between the gill opening and the base of the caudal equal 42-50, vertebrae 45-49, ventral scutes 32-36, and prepelvic scutes 17-19. The postpelvic scutes number 13-17, gill rakers about 125-158. The proportions as percent of standard length are: body depth 30-40, caudal peduncle depth 8.5-11, and head length 19-28. The eye diameter is 6-8.5,maxillary length=8.8-12, anal fin base=16.7-21.5, pelvic fin length=8.5-11.5, pectoral fin length=17-21, length of last dorsal ray=33.3-40.4; body elongate, strongly compressed, ventral outline convex, dorsal outline only slightly convex; head small, snout lacking definite median notch; maxillary broadly rounded, reaching anterior margin of pupil; mandible slightly projecting, upper margin forming obtuse angle; jaws toothless; scales thin, deeper than long with somewhat irregular membraneous edges; predorsal median line scaled to nape; anal and dorsal bases with low sheath of scales; last dorsal ray elongate, more than twice that of next longest ray; gill rakers increase in number with age; bluish-green to silvery-blue above, silvery on sides and below, usually with dark shoulder spot, dorsal scale rows with dark lines, fins translucent, tips of dorsal fin and caudal lobes dusky; maximum length about 300 mm *1229*; larvae and juveniles are also described *1229*; REPRODUCTION: Spawning was reported from Straights of Florida, eastern Gulf of Mexico, and North Carolina *3709,3708,1383*; based on egg collections, spawning occurs where depths are <50 m, mostly at depths Species herring, Atlantic thread Species Id M010047 Date 27 AUG 96 potential yield ranging from 60300 to 120600 metric tons *3708*; larval mortality from time of spawn until 19 days (15.5 mm SL) was 98% to 99+% *3708*; AQUATIC/TERRESTRIAL ASSOCIATIONS: juveniles often mix with schools of juvenile Harengula pensacolae and/or Sardinella aurita *3713,3707* REFERENCES FOR LIFE HISTORY- 1229, 1362, 3709, 3713, 3714, 3708, 1383, 3716, 3717, 3858, 3718, 3712 and 3707 Life History - 2
