“…For both months, assemblages' structure was controlled by the interactions between larval biological characteristics at the ontogenetic and taxonomic levels, and water components. Segregation between development stages is usually explained by a gain, or change, in biological abilities that enables the older larvae to use a wider -or new -range of environments (Simonović et al 1999, Sarpedonti et al 2000, Pinder et al 2005. In this study growing Clupeiforms moved from the farmost stations, S1 and S5, to the stations closer to the waterfront.…”

Spatio-temporal distribution of fish larvae in relation to ontogeny and water quality in the oligohaline zone of a North Brazilian estuary

2013

Larval fish assemblage in Guajará Bay was studied through four quarterly field campaigns and discussed in relation to individuals' development stages and exposure to contaminants poured out by the Pará State Capital City, Belém. Larval densities were low and diversity extremely poor with a strong dominance of clupeids, engraulids and, to a lower extent, sciaenids. The main spawning season was registered at the onset of the rainy period. Pre-flexion and flexion clupeiforms remained in the farmost stations from the city while post-flexion larvae were found near urban activity centres. Unlikely, pre-flexion and flexion sciaenids were scattered along the city waterfront. Post-flexion larvae were rare; it is suggested that sciaenids use the bay as a transitory route between their spawning grounds and more distant nursery grounds. The waters around the city of Belém showed signs of contamination. However, based on the literature, Guajará Bay environmental quality at the time of the study was suitable for fish larvae life. Nitrate with pH best explained larval distribution. Resumo: O padrão de distribuição das larvas de peixes na Baía do Guajará foi estudado através de coletas trimestrais e discutido em relação aos estágios de desenvolvimento dos indivíduos e a exposição dos mesmos aos contaminantes despejados pela Capital do Estado do Pará, Belém. A densidade e a diversidade larval foram baixas com forte dominância dos clupeídeos, engraulídeos e, em menor grau, os cianídeos. O principal período de reprodução foi definido no início do período chuvoso. Larvas de Clupeiformes em pré-flexão e flexão foram encontradas nos pontos de coletas mais afastados da cidade, enquanto aquelas em pós-flexão prevaleceram nas margens da cidade. Por outro lado, os cianídeos em pré-flexão e flexão foram capturados perto dos centros de atividade urbana, enquando aqueles em pós-flexão foram pouco abundantes. É sugerido que a baía se encontra na rota migratória dos cianídeos entre a área de desova e os berçários mais distantes. Apesar das águas no entorno da cidade de Belém mostraram sinais de contaminação, a qualidade ambiental na Baía do Guajará no momento do estudo estava apropriada para a vida das larvas de peixes. Nitrato com pH foram as variáveis que melhor explicaram a distribuição larval. Palavras-chave: Ictioplâncton, Amazônia, impacto urbano, Belém.

“…In contrast to the scarce information available about the handling efficiency of Squalius species, the habitat requirements of cyprinids are well known, and generally the preference for high velocity and deeper areas increases with fish age (e.g., Simonović et al 1999;Kováč et al 2006;Copp et al 2010). Previous studies have demonstrated in various Iberian Squalius species that adults occupy coarser substrata, faster-flowing areas and deeper areas than young-of-year and juveniles (Santos & Ferreira 2008;Martínez-Capel et al 2009).…”

Multivariate prey trait analysis is a functional approach to understand predator-prey relationships. Here, seven macroinvertebrate ecological traits have been used for the analysis of trophic ecology of co-occurring age classes of Northern Iberian chub Squalius carolitertii, a cyprinid fish species. The present study identified several key factors in the handling efficiency and habitat utilization for feeding of S. carolitertii that may have a wider application, particularly for other cyprinid species. The results revealed a remarkable similarity in the feeding behaviour among age classes, suggesting a foraging behaviour convergence among them in both prey-handling efficiency and feeding habitat utilization. Nevertheless, some age classes showed clear preferences for particular categories of ecological trait; for example, age 1 showed a clear ability to feed on flattened prey items, whereas ages 2 and 3 were able to feed on preys with different body shape due to their general distribution in the fuzzy principal component analysis (FPCA). Finally, this study shows how multivariate approaches can complement traditional diet analyses, and the method has wide applicability across life-stages of cyprinid species.

“…In addition, after treatment with 2-mercapto-1-methylimidazole, 21 zebrafish larvae were also shown to develop a slimmer body shape. These findings The early development of fish larvae is accompanied by complex shape changes, 32 which are related to the functions of different organs to adapt to a new lifestyle (Osse,33 1989; Simonović et al, 1999;Russo et al, 2007). Different growth rates of various 34 parts of the body or allometric growth are common phenomena during this period 35 ( thawing.…”
