Species profiles are literature summaries of the taxonomy, morphology, life history, and environmental requires of coastal aquatic species. They are prepared to assist in environmental impact assessment. The pinfish Lagodon rhomhboides is an abundant and important marine fish which can alter estuarine epifaunal seagrass communities as well as serve as forage for commercial and sport fishes. Pinfish have been extensively used in pesticide bioassays, physiological experiments, and ecological studies. Adults and most large juveniles move offshore in late fall. They spawn offshore during fall and winter. Semibuoyant eggs hatch after 48 hours at 18 C. Larval pinfish 11 mm TL move into estuarine nursery grounds soon after hatching, where they feed on calanoid copepods. Juvenile pinfish are most abundant in seagrass-covered habitats where they feed on amphipods. Pinfish change their diet as body size and tooth structure changes. Growth increments were 65 to 110 mm, 55 mm, and 45 mm long at the end of their first through third years of life, respectively. Pinfish are used for food and bait by anglers and are combined with unclassified species or industrial fish in commercial fisheries statistics. Pinfish inhabit inshore waters when temperatures are above 10 C and below 35 C. They are abundant in a broad range of salinities. Keywords Estuaries GrowthPhysiology.
