Weight-length relationships for intertidal fish fauna in a mangrove estuary in Northern Brazil

Abstract

Summary Weight‐length relationships (WLR) are presented for 40 fish species inhabiting the mangrove creeks in the Curuçá Estuary in Northern Brazil. Samples were taken bimonthly between July 2003 and 2004 with a fyke net. This study represents the first reference available on WLR for 28 fish species.

Length weight relationship of 73 fish species caught in the southeastern inner continental shelf region of Brazil

“…Two species of Pristigasteridae, although captured in different environments with different abundance values, exhibited an isometric growth (b = 3), that is, the individuals keep the same body form and proportional growth in all size classes. Similar growth patterns for Carangidae and Ariidae species were obtained by Giarrizzo et al (2006) in the northeastern Brazilian estuary.…”

Growth of the silverside Atherinella brasiliensis in a subtropical estuary with some insights concerning the weight-length relationship

“…The weightlength relationship is characterized by positive allometric growth. Concerning parameters of the von Bertalanffy growth curve, asymptotic lengths are estimated between 11.3 and 17 cm and the growth constant ranging between 0.82-0.89 (year -1 ); resulting in longevity estimates of slightly more than three years (Paiva-Filho and Giannini 1990, Haimovici and Velasco 2000, Pessanha and Araújo 2001, Giarrizzo et al 2006, Macieira and Joyeux 2008, Mazzei et al 2011, Freire et al 2012, Costa et al 2013, Franco et al 2013.…”

Length-weight and length-length relationships for rockpool fishes on the Brazilian coast

“…Caranx latus (Agassiz, 1831), Diplodus argentus and Abdefduf saxatilis (Linnaeus, 1758)] were represented by small length ranges due to the nursery function of the sampled tidalpools. Therefore, LWRs biased by inclusion of small specimens, should be used with caution (Giarrizzo et al 2006). As pointed out by Petrakis and Stergiou (1995), the application of these LWRs should be limited to the size ranges used to estimate the parameters.…”
