Abstract

Length-weight and length-length relationships were determined for nine fish species of Rocas Atoll, Fernando de Noronha and Trindade Island. Samples were conducted in 2014 (Rocas) and 2015 (Noronha and Trindade) in tidepools using anaesthetic clove oil and hand nets to collect fish fauna. Four species (Stegastes rocasensis, Scartella itajobi, Starksia multilepis and Bathygobius brasiliensis) are endemic from the Noronha-Rocas ridge, two are endemic from the Trindade-Martin Vaz insular complex (Scartella poiti and Malacoctenus brunoi), and three species have a widespread distribution. All relationships are novel for science.
