Length-weight relationships of six fish species from São Marcos Bay, Northeastern Brazil

Abstract

Length‐weight relationship parameters were calculated for six fish species from São Marcos Bay, in Northeast Brazil (the segment between 02°35′55″S and 44°20′58″W; 02°34′53″S and 44°21′48″W; 02º42′25″S and 44º26′46″W). The specimens were caught quarterly from April 2010 to February 2013, using monofilament gillnets (2, 4 and 6 cm between knots) from 100 m to 3,000 m long and 4 m to 6 m high. The present study covers a much wider size range for four species and adds new information for the maximum length of Notarius bonillai.

Length‐weight relationships of seven fish species from Amazonian Equatorial coast, Brazil

“…The length‐weight relationship (LWR) is important data for fishery research (Le Cren, ; Froese, ) but scarcely known for fishes from Amazon Equatorial Coast (Aguiar‐Santos, Sampaio, Barroso, Nunes, & Piorski, ). The Itapecuru River is an important regional river because it is the main source of water to the cities set along its course.…”

Length–weight relationship of thirteen demersal fishes from the tropical Brazilian continental shelf

“…Freire et al, ; MacIeira & Joyeux, ; Passos, Schwarz, Cartagena, Garcia, & Spach, ) regions. In the continental shelf of northeast Brazil, an area of high biodiversity where many threatened and near‐threatened species occur (Eduardo et al, ), only a few LWR references are available for estuarine and shallow water (0–30 m) species (e.g Aguiar‐Santos, Sampaio, Barroso, Nunes, & Piorski, ; Joyeux, Giarrizzo, MacIeira, Spach, & Vaske, ; Viana et al, ). Here new LWR information is provided for 13 species of demersal fishes occurring along the Brazilian northeast continental shelf.…”
