Abstract

Marine inshore trawl catches of 12 species of estuarine-associated fishes are reported together with their depth and length distributions. Underwater observations of four additional species, made during 122 SCUBA dives over rocky substrates, are also recorded. The data revealed three ecologically distinct groups of inshore fishes: typically marine species that only use marine inshore nursery grounds; an intermediate group that uses mainly marine inshore nurseries plus estuarine nurseries to a limited extent; and a specialized group that is dependent on estuarine nurseries.
