Description of Larval Jenkinsia Lamprotaenia (Clupeidae, Dussumieriinae) and Their Distribution off Barbados, West Indies
Abstract:Young Jenkinsia lamprotaenia were collected with towed nets and an airlift sampler off Barbados between June 1972 and December 1973. Larvae of standard lengths 5.5 mm to 15.2 mm are described and illustrated. Transformation begins between 12.5-mm and 15.2-mm standard length. Adult values of most body proportions are reached by 16.0 mm, but body depth attains its adult value at 27.0 mm and scales are first developed at 20.8 mm. Larval J. lamprotaenia can be distinguished from other Caribbean and western North Atlantic clupeid larvae by myomere counts, pigmentation, gut structure, and postdorsalpreanal myomere counts. Larval J. lamprotaenia were rare in plankton tows, although the adults were abundant in shallow waters off Barbados. An epibenthic habitat for the larvae is suggested by their presence in epibenthic samples taken with the airlift sampler.
