“…However, individuals of all functional groups occurred in all salinity sectors and, thus, this metric was not useful for differentiating assemblages along the salinity gradient using a mean model. Our results differed from those of other studies, which emphasized the importance of functional groups in determining fish assemblages along salinity gradients (ELLIOTT; DEWAILLY, 1995;MATHIESON et al, 2000;BOUCHEREAU, 2004;WHITFIELD, 2012).…”

“…Using a traditional taxonomic approach, along with an analysis of FG, represents a holistic approach to describing the structure of fish fauna (FRANCO et al, 2008). Moreover, because functional aspects provide important cues regarding ecosystem health, this approach may help in decisionmaking processes related to the management of estuarine areas (MATHIESON et al, 2000).…”

A B S T R A C THere we test the effects of the east-west salinity gradient in the subtropical Paranaguá Bay Estuarine Complex (PEC) on the structure of shallow water fish fauna, determined according to taxonomic (families and species) and functional composition metrics. A total of 152 species were observed. The families with the largest number of species were the Sciaenidae, Carangidae, Haemulidae and Gobiidae. The most abundant species were Atherinella brasiliensis, Harengula clupeola, Anchoa januaria and Anchoa tricolor. Marine stragglers dominated in number of species, followed by marine migrants and estuarine species. Most species were zoobenthivores, followed by piscivores and zooplanktivores. Families and species more frequently associated with estuarine conditions dominated in the mesohaline sector, and those more frequently associated with marine conditions dominated in the euhaline sector. The fish assemblages along the estuarine salinity gradient were found to be better characterized by taxonomic metrics than by functional ones. This is most likely because individuals of all functional groups inhabit all salinity sectors, and thus these metrics are not useful for differentiating assemblages along salinity gradients. Our results differ from those of other studies in tropical and subtropical estuaries, which have emphasized the importance of functional groups in determining fish assemblages along salinity gradients. R E S U M ONeste trabalho foi testado o efeito do gradiente de salinidade do eixo-leste oeste do sistema subtropical Complexo Estuarino da Baía de Paranaguá na estrutura dos peixes de águas rasas, determinado de acordo com as métricas taxonômica (famílias e espécies) e de composição funcional. Um total de 152 espécies foi registrado. As famílias com maior número de espécies foram Sciaenidae, Carangidae, Haemulidae e Gobiidae. As espécies mais abundantes foram A. brasiliensis, H. clupeola, A. januaria e A. tricolor. Os visitantes marinhos dominaram em número de espécies, seguidos pelos migrantes marinhos e estuarinos. A maioria das espécies são zoobentívoras, seguidas pelas piscívoras e zooplanctívoras. As famílias e espécies mais relacionadas com condições estuarinas dominaram no setor mesohalino e aquelas mais relacionadas com condições marinhas dominaram no setor euhalino. A métrica taxonômica foi mais eficiente na caracterização das assembleias de peixes ao longo do gradiente estuarino de salinidade do que a funcional. Isso ocorreu principalmente porque indivíduos de todos os grupos funcionais estiveram presentes ao longo de todos os setores de salinidade, invalidando o emprego dessa métrica na diferenciação das assembleias nos diversos setores. Nosso resultado foi diferente do encontrado em outros estuários tropicais e subtropicais, que enfatizaram a importância dos grupos funcionais na estruturação das assembleias de peixes ao longo de um gradiente de salinidade.

“…The Mondego Estuary fish assemblage was similar to the typical European Atlantic seaboard estuarine community as defined by Elliott and Dewailly (1995), Pihl et al (2002) and by Mathieson et al (2000) for tidal marshes, with a dominance of estuarine residents (ER) and species that use estuaries as nursery areas (NU). The present results corroborate the findings of Malavasi et al (2004), in which the estuarine residents comprise about 50% of the fish community of the Venice Lagoon.…”

“…Fish larvae were classified into the following ecological guilds, according to their biology and typical behaviour reported in the literature (Mathieson et al 2000, França et al 2009): estuarine residents (ER), which spend their entire lives in the salt marsh or estuary; marine seasonal migrants (MS), which migrate into the salt marsh or the estuary because of diet or reproductive needs; marine adventitious species (MA), which occur irregularly in salt marsh, and marine juvenile species (MJ), which spend the first stages of their life cycles in the salt marsh or estuary. Abundance of fish larvae and eggs was expressed as number of individuals /100 m 3 (number of individuals / filtered water volume × 100), and meso-and macro-zooplanktons as number of individuals m -3 (number / filtered water volume).…”

Summary: Salt marsh areas in the Guadiana estuary are important nursery sites for many fish species of commercial and recreational value. More effective protection measures should be adopted as the area is highly affected by anthropogenic and natural threats. Studying larval fish communities in these impacted nursery areas will be relevant to the management of local ecosystems and to larval fish ecology in general. Spatial and seasonal distribution and the effect of environmental factors on the larval fish community of this ecosystem were studied for one year (April 2010 to March 2011). Larvae were sampled monthly in parallel with phytoplankton and zooplankton. Hydrological data and physical parameters were monitored. A decision tree model was used to assess the influence of environmental factors on the larval fish community. A total of 130 larvae and 1171 eggs were caught. Diplodus sargus, Sardina pilchardus, and Pomatoschistus microps were the most abundant larval fish species. The peaks of fish larvae abundance occurred in March and April. The output of the model demonstrates that the abundance of larval fish is determined by the abundance of eggs, zooplanktonic food, and water flood and flow. This study shows the importance of the Guadiana salt marsh as an area for fish nursery and highlights the need for conservation of this area.Keywords: larval fish; salt marsh; Guadiana estuary; fish eggs; food availability; flooding events; river flow.Factores ambientales que afectan a la comunidad de larvas de peces en las marismas del estuario del Guadiana (Algarve, Portugal) Resumen: Las zonas de marisma en el estuario del Guadiana constituyen zonas de cría importantes para muchas especies de peces de valor comercial y recreativo. Deberían ser adoptadas unas medidas de protección más efectivas ya que el área está altamente afectada por amenazas tanto antropogénicas como naturales. El estudio de las comunidades de larvas de pez en estas áreas de cría más impactadas será relevante para la gestión del ecosistema local y para la ecología de las larvas de pez en general. La distribución espacial y estacional, y el efecto de factores ambientales en las comunidades de larvas de pez de este ecosistema fueron estudiados durante un año (abril de 2010-marzo de 2011). El muestreo de las larvas fue realizado mensualmente en paralelo con el de fitoplancton y zooplancton. También fueron monitoreados datos hidrológicos y parámetros físicos. Un modelo de Árbol de Decisión fue utilizado para evaluar la influencia de factores ambientales en la comunidad de larvas de pez. Fueron recogidos un total de 130 larvas y 1171 huevos. Diplodus sargus, Sardina pilchardus y Pomatoschistus microps fueron las especies más abundantes. Los picos de abundancia de larvas de pez ocurrieron en marzo y abril. Los resultados del modelo demuestran que la abundancia de larvas de pez viene determinada por la abundancia de huevos, la comida zooplanctónica, los eventos de inundación y el caudal del río. Este estudio muestra la importancia de las marismas del Gua...
