The USVI larval distribution and supply study completed its third research cruise during April 7-20, 2009. Ichthyoplankton sampling yielded 314 samples (217 MOCNESS and 97 bongo) from 105 stations and 125 fish families were identified from a total of 24,593 larvae collected. MOCNESS (Multiple Opening and Closing Environmental Sampling System) samples were collected from 100 m to the surface at 25 m increments while Bongo samples were collected from just below the sea surface for 10 minute intervals at each station. A total of 23,512 larvae have been successfully identified to taxonomic family level or beyond, with only 4.2% or 1,041 categorized as unidentifiable due to early stage at development or damage that occurred during the sample collection and/or processing. Approximately 76 % of the fish larvae samples were represented by 20 principle families: Bregmacerotidae, Labridae, Myctophidae, Carangidae, Clupeidae, Mullidae, Sternoptychidae, Scombridae, Eleotridae, Gobiidae, Apogonidae, Sphyraenidae, Serranidae, Coryphaenidae, Pomacentridae, Gonostomatidae, Chauliodontidae, Epigonidae, Bythitidae, and Lutjanidae. All samples collected have been identified using taxonomic keys and a subsample will be identified using genetic techniques.
