Length–weight relationships for three small reef-fishes from the Argentine coast: Helcogrammoides cunninghami (Smitt, 1898), Ribeiroclinus eigenmanni (Jordan, 1888), and Hypleurochilus fissicornis (Quoy and Gaimard, 1824)

Abstract

In this study the first length–weight relationships are provided for Helcogrammoides cunninghami and Ribeiroclinus eigenmanni inhabiting subtidal rocky areas in northern Patagonia, and for Hypleurochilus fissicornis inhabiting intertidal rocky areas in Buenos Aires Province. Specimens were collected between 2009 and 2016, from seven different locations in northern Patagonia and Buenos Aires Province (Southwest Atlantic Coast; 37°–42°S), using a trawling dredge or a small hand net. New maximum lengths were recorded for R. eigenmanni and H. fissicornis.
