Vertical Distribution of Fish Larvae off the Florida Keys, 26 May–5 June 1989
Abstract:A preliminary description of the vertical distribution of fish larvae offshore of the Florida Keys was derived from quantitative analysis of the fish families represented in the catch from selected stations on the 26 May to 5 June 1989 cruise of Project SEFCAR (Southeastern Florida and Caribbean Recruitment). Eight nighttime samples were taken at stations >150 m deep by MOCNESS tows with individual nets sampling 25 m vertical depth strata. Larvae of 65 families of fishes were identified. The depth distribution of the 14 most abundant families was explored. These families comprised three groups based on the observed depth of 50% or more of their abundance. The Scombridae, Carangidae, Labridae, and Bothidae occurred <25 m deep. The Gonostomatidae, Gobiidae, Myctophidae, Serranidae, Paralepididae, Scorpaenidae, and Bregmacerotidae occurred <50 m deep. The Paralichthyidae, Synodontidae, and Phosichthyidae occurred >50 m deep. The larvae of the remaining 51 families also could be assigned to these three vertical depth categories with approximately equal numbers of families in each depth category but greatest total abundance in the second category (0–50 m).
