Growth parameters estimates for a small fish of the Pantanal, Brazil: Moenkhausia dichroura (Characiformes; Characidae)

Abstract: Growth parameters were estimated for Moenkhausia dichroura (Kner, 1858) (Characiformes, Characidae), a smallsized and very abundant fish of the Pantanal lentic habitats commonly known as "pequira ". A method based on the length frequencies distribution and the ELEFAN I routine from the FISAT program were used. The fish were collected in the Baia da Onça, an oxbowlake of the sub-region Pantanal of Aquidauana, Mato Grosso do Sul, Brazil, from June to December 1988. The standard length of the captured fishes rang… Show more

“…The growth parameter estimates for small-sized species in the Ivinhema River basin follow this same pattern (LOURENÇO et al 2008). A similar pattern was also reported for the Moenkhausia dichroura (Kner, 1858) population sampled in an oxbow lake located on the right margin of the Aquidauana River in the Patanal Wetland (Brazil) (CUNHA et al 2007).…”

“…The growth performance estimate () for the species was 3.80, which is close to estimates reported for other species of the same family, such as Serrapinnus notomelas (Eigenmann, 1915) ( = 3.027), Bryconamericus stramineus Eigenmann, 1908 ( = 3.208) (LOURENÇO et al 2008), Roeboides paranensis Pignalberi, 1975 ( = 3.64) (CAPISTRANO-SANTANA et al 2004), and M. dichroura ( = 3.75) (CUNHA et al 2007). Estimation of growth and asymptotic length using the same model permits the comparison of performance among fishes with similar shapes (MATEUS & PENHA 2007).…”

“…One way to obtain these parameters is to carry out growth studies, which involve age estimates from bony structures or even length-frequencies (Campana and Thorrold, 2001;El-Haweet et al, 2005;Cunha et al, 2007;Romo-Curiel et al, 2015), but only a small percentage of South American species has been studied (Dei Tos et al, 2010). Together with growth and reproduction studies, mortality rates are essential to understand the production dynamics of populations.…”

“…Além disso, a época de menor crescimento coincidiu com o início do período reprodutivo (Gomiero et al 2008) e a menor intensidade da atividade alimentar (Botelho et al 2007), assim, a energia armazenada investida no crescimento somático passa a ser direcionada para a maturação dos gametas. Nunes & Hartz (2006) O aspecto polimodal da distribuição de frequência de comprimento, com a presença de seis coortes, é compatível com a informação de tratar-se de uma população bem estabelecida no ambiente (Cunha et al 2007). O recrutamento, que é a entrada de novos indivíduos na população, ocorre entre abril, maio e outubro, coincidindo com o fim do período reprodutivo da espécie (Gomiero et al 2008).…”

“…Esses dados contêm informações sobre o comprimento médio em cada grupo etário, juntamente com a posição das modas associadas com as coortes (Basson et al 1988). Este método foi utilizado para estimar parâmetros populacionais em diversas espécies: Moenkhausia intermedia (Lizama & Ambrósio 2003), Roeboides paranensis (Capistrano-Santana et al 2004), Characidium lauroi e C. alipioi ), Moenkhausia dichroura (Cunha et al 2007), Brycon opalinus ) e Cyphocarax modestus (Carmassi et al 2008).…”
