“…Such information can benefit fishery scientists in the fishery diagnoses and management. The LWR is an excellent monitoring tool in commercial fishing landings (King, 1995;Gubiani et al, 2009;Vaz-dos-Santos and Gris, 2016), and weight is a good estimator of fish welfare or condition in a given environment (Vazzoler, 1996).…”

The length-weight relationship of fish species is widely used in fisheries monitoring programs and it is an important tool for proposing stock management measures. The objective of this study was to estimate the growth parameters of 34 species belonging to the fish community captured by experimental fishery in the Três Irmãos reservoir, Tietê river. The biological and ecological characteristics of these species are also presented in order to understand the profile of the present fish community. The fish were collected during ten experimental fishing seasons between October/2015 and February/2018, with quarterly frequency using four types of fishing gear. All fish captured were identified and the total length-TL (cm), standard length-SL (cm) and total weight-TW (g) were measured. The length-weight relationship was established using the linear regression TW vs SL (log-transformed): log (TW) = log (a) + b log (SL), where a is the regression curve intercept (coefficient related to body shape) and b is the coefficient of regression (exponent indicating the type of growth). A total of 7,319 individuals was identified, comprising five orders: Characiformes (7 Families), Siluriformes (5 Families), Perciformes (1 Family), Cichliformes (1 Family) and Cyprinodontiformes (1 Family). The most abundant species were Plagioscion squamosissimus (N=1,513), Geophagus sveni (N=1,160), Serrasalmus maculatus (N=1,049) and Metynnis maculatus (pacu-CD) (N=974), all of them being target species for professional artisanal fishing, with the exception of pacu-CD, which is discarded since it has no commercial interest. From the whole set of analyzes 15 species (44.1%) have positive allometric growth type (3.15≤ b ≤3.59), 14 (41.2%) isometric (2.98≤ b ≤ 3.08), and 5 (14.7%) negative allometric growth (2.7 ≤ b ≤ 2.90). Among the species studied nine reached a maximum length above that of the FishBase: Cichla piquiti (TL= 55.4 cm), Crenicichla haroldoi (SL= 21.5 cm), C. jaguarensis (SL= 23.5 cm), Cyphocharax nagelii (TL= 22.9 cm), Hypostomus ancistroides (TL= 28.5 cm), Metynnis maculatus (TL= 19.5 cm), Piaractus mesopotamicus (SL= 60.0 cm), Roeboides descalvadensis (SL= 11.3 cm) and Schizodon borellii (TL= 40.0 cm).

“…Other studies corroborate the positive allometric growth of both sexes of M. americanus in these localities. It demonstrates that this species grows more in weight than in length in subtropical latitudes (Haluch et al 2011, Passos et al 2012, Dias et al 2014, Vaz-dos-Santos & Gris 2016. Growth curve parameters and longevity also differed between the studies that analyzed M. americanus at different latitudes (Gianini & Paiva-Filho 1992, McDowell & Robillard 2013, Clardy et al 2014.…”

Menticirrhus americanus were sampled (n = 393) from two beaches (P1 is an estuarine beach near the mouth of the Paranaguá Estuarine Complex, and P2 is a beach adjacent to the Paranaguá Estuarine Complex) in the subtropical region of the western South Atlantic waters between August 2015 and June 2016. This study aimed to identify the spawning season and the age structure for M. americanus using two sampling methods. For sampling at the P1 beach, seine, line, and pole were used, while samples from the P2 beach were obtained from the artisanal fishers. Females were numerically dominant in all sampling months at both sites except for February when the males became dominant. The species exhibited a protected reproductive season with multiple spawning peaks between August and December. Males and females were captured at all gonadal development stages and ages between 1 and 6 from both sites. At first maturity, the length of the females was 16.3 cm, and the mean age at first maturity was 1.3 years. Individuals aged between 1 and 3 years were dominant (68%). The results suggested that young and adults of the M. americanus use the same habitats throughout their ontogeny.

“…The fish growth is a parameter described in many studies. Tools as the otoliths (Costa et al, 2013;Maciel et al, 2019;Soeth et al, 2019) and the length-weight relationships (LWR) are used mainly with marine and estuarine species as a means of estimating the relative growth (Bervian and Fontoura, 2007;Vaz-dos-Santos and Gris, 2016;Carvalho et al, 2017). The LWR are important tools for ichthyology (Froese, 2006), and its parameters are useful to estimate biomass (Le Cren, 1951), elaboration of stock and growth models (Haimovici and Velasco, 2000) and life stage (Possamai et al, 2/9 2020).…”

“…Species with wide latitudinal distribution are widely used to understand the influence of environmental parameters on growth (e.g. Atherinella brasiliensis) (Paiva-Filho and Giannini, 1990;Haimovici and Velasco, 2000;Pessanha and Araújo, 2001;Giarrizzo et al, 2006;Bervian and Fontoura, 2007;Macieira and Joyeux, 2009;Mazzei et al, 2011;Freire et al, 2012;Costa et al, 2013;Franco et al, 2013;Vaz-dos-Santos and Gris, 2016;Carvalho et al, 2017;Possamai et al, 2019).…”

The length–weight relationships (LWR) are important tools for ichthyology, they are useful to demonstrate the environmental influence on growth. In this study we estimate the LWR of the Atherinella brasiliensis in the shallow areas of the São Francisco river estuary and compare the growth of this specie in different environments of the Brazilian coast. Specimens of Brazilian silverside (A. brasiliensis, n = 3483), between 2.1 and 13.6 cm in length, were caught in the shallow areas of the São Francisco River estuary between May 2017 and April 2018. The length-weight ratio of the species was represented by the equation y=0.0047x3.0913. Frequency distribution indicates that the species is present in the shallow areas of the São Francisco River estuary in all its ontogenetic stages and apparently reproduces throughout the year with constant input of recruits into the population. Von Bertalanffy’s growth model and longevity were adjusted to reach asymptotic length (L∞) of 14.7 cm, growth coefficient (K) of 0.91 year-1 and longevity (A95) of 3.25 years. The analysis of variance revealed differences for the maximum total length. However, the differences found between the present study and data available in the literature appear to be caused by environmental and methodological differences.
