A total of 1095 fish were analysed, representing 15 species. In total 1384 particles of plastic debris were recovered from the gastrointestinal tracts of 552 specimens belonging to 13 species, and all consisted...

The dynamics of microfilament (<5 mm) ingestion were evaluated in three species of snooks. The ingestion of different colours and sizes of microfilaments were strongly associated with the spatio-temporal estuarine use and ontogenetic shifts of snooks. Their feeding ecology was also analysed to assess dietary relationships with patterns of contamina...

Research on estuarine ecology in South America (SA) increased quali-quantitatively since the early 1980 in search of consistent recommendations for estuarine conservation. The most important ecological theory achieved is that the seasonal fluctuation of the salinity gradient creates an ecocline influenced by gradual changes between river-dominated...
Article
This study assessed the seasonal patterns of habitat utilization, feeding ecology and microplastic contamination in different ontogenetic phases of sympatric snooks (Centropomus undecimalis and C. mexicanus) inhabiting a tropical estuary. More than 50% of snooks, in all ontogenetic phases, ingested microplastics (1.5 ± 0.1 and 1.4 ± 0.1 particles i...

Anthropic processes degrade quality of estuarine environments, resulting in a worrying form of water pollution. The objective of the study was to describe and discuss interannual and seasonal changes of water quality based on indicators monitored in Goiana River estuary, as well as identifying the main drivers of such changes. We considered three e...
Article
Estuarine pollution imposes rapid, increasing and lasting environmental modifications. In the present review, especial attention is given to estuaries in South America (SA), where legislation, policies and actions to guarantee environmental quality remain ineffective. There, the majority of estuaries face uncontrolled occupation of its margins by u...

Waters entering the small estuaries of the Brazilian north-east originate from drainage basins that cross semi-arid and tropical rainforest areas at various levels of use and conservation. Such rivers are often under heavy demand for water supply and other services, such as effluent dilution. The present study examines four consecutive years (2006–...

Ecocline is defined as a “gradation from one ecosystem to another when there is no sharp boundary between the two” containing relatively heterogeneous communities influenced by gradual changes between river-dominated to marine-like waters. It creates heterogeneous habitats, differing in abiotic characteristics, mainly water salinity. Estuarine fish...

Fisheries in Brazil, the country with most territory in South America, is not comprehensive at all. The lack of precise historical data is the main concern faced by perspectives of fishery management. The majority of data are simplistic records of extrapolated biomass published by federal entities regardless the habitat from where fish resources we...

Seasonality was a stronger influence in the ichthyoplankton assemblages around the Saint Peter and Saint Paul Archipelago (SPSPA) than distance from the islands. Plastic debris were ubiquitous and although it presented diel trends, no other spatiotemporal patterns was showed. Larval Oxyporhamphus micropterus was the most important taxa (29.37% of t...

The influence of the lunar cycle on prey availability, diet shifts and overlap between larval Anchovia clupeoides and Cetengraulis edentulus was evaluated in mangrove creeks of the Goiana Estuary. Copepod eggs were highly abundant in the first and last quarter, at the full moon and zoea of Ucides cordatus (Ocypodidae) in the new moon. The Engraulid...

The plastic debris contamination, feeding ecology and habitat use of Cynoscion acoupa, an economically important species, were studied in relation to spatial, seasonal and ontogenetic aspects in a tropical estuary. The human impact on the environment was evident in the studied species, reflecting the high contamination of the diet of these fish wit...

The origins of this special issue date back to 2009, when a group of South American fish scientists united to prepare a manuscript on Fish and aquatic habitat conservation in South America for a Journal of Fish Biology special issue on the conservation of fishes (vol. 76, Number 9, June 2010). At that time, 18 co-authors from different regions and...
Article
In South America, the conservation of natural resources, particularly in relation to water and aquatic fauna, is an often-discussed issue. Unfortunately, there is still a large gap between thoughts and action. Scientists from different countries of the continent have however, produced a significant body of literature that should finally become the...

The American continent stretches for about 14000 km from north to south, spanning over 127º of latitude (72º N to 55º S) and covering approximately 42.5 million km² (Kohn and Cohen 1998). The continent is bordered by the Atlantic Ocean on the east and the Pacifi c on the west. The latitudinal range confers important biogeographical and ecological c...

Estuarine ecosystems are characterized by a constantly changing mixture of saltwater and freshwater (McLusky, 1989). The flux of saltwater and freshwater presents physiological challenges to estuarine organisms. Gradients of salinity, for example, restrict many animal species in the adjacent sea or rivers from entering estuaries. In highly stratifi...

Inland fisheries are vital for the livelihoods and food resources of humans worldwide but their importance is underestimated, probably because large numbers of small, local operators are involved. Freshwater Fisheries Ecology defines what we have globally, what we are going to lose and mitigate for, and what, given the right tools, we can save. To...

Microplastic pollution is a global issue. It is present even in remote and pristine coastal and marine environments, likely causing impacts of unknown scale. Microplastics are primaryand secondary-sourced plastics with diameters of 5 mm or less that are either free in the water column or mixed in sandy and muddy sediments. Since the early 1970s, th...

There are no strict limits on the spatial or temporal scale of a fish assemblage (Miller, 2002). It may be an assemblage in a single season and region (e.g., a fish assemblage of an estuarine main channel during the late rainy season) or at specific times and locations (e.g., fish assemblages among different estuaries in South America). Research on...

Most fishes that inhabit estuaries are originally marine species. To enter estuaries, offshore-spawned species utilize flows at the bottom of the water column upstream to nursery areas. Some other species are retained in a certain position in the estuary next to the halocline and benefit from fast growth due to high prey availability and reduced ri...

South American countries share, in spite of their wide variety of habitats, their main patterns of use of water resources. One of the major historical problems was the centuries-long delay in approaching river basins as integrated systems. Consequently, managerial systems still have to deal with the old segmented idea of disconnection between river...
