“…As far as Prochilodus lineatus research is concerned, its role as indicator of contamination caused by anthropogenic activity (Palermo, Risso, Simonato, & Martinez, 2015); its migratory behaviour (Capeleti & Petrere Jr, 2006) and its relevance on artisanal fishery (Payne & Harvey, 1989) have been extensively studied. However, there is no published research on their endogenous proteases or the use of the skin of this species as a source of collagen.…”

Acid proteases from sábalo stomach mucosa were recovered using salting-out procedure. This single step produced an enzyme extract purified 1.8-fold over the crude extract with a recovery of 45.1% of its initial proteolytic activity. Sábalo proteases exhibited the highest activity at 45 °C-pH 2.0, showed pH stability between 2.0 and 5.0 and retained more than 70% of its activity after incubation at pH 7.0 for 2 h. Fish extract was unstable at temperatures greater than 45 °C. Its activity was inhibited by pepstatin A but not by PMSF, while EDTA and SDS showed partial inhibitory effects. Presence of CaCl and MgCl increased the proteolytic activity, while increasing concentrations of NaCl strongly decreased it. In addition, compared to the acid extraction method, the use of sábalo enzymatic extract increased 1.7 times the yield of collagen extraction.

“…The same was found in the Upper Pantanal (Brazil), in the Poconé and Nossa Senhora do Livramento regions (Upper Paraguay River), where piscivorous or detritivorous species such as Pimelodus muculatus, P. fasciatum, P. lineatus, Salminus maxillosus, P. corruscans, Acestrorhynchus altus, Serrasalmus nattereri and H. malabaricus also had high levels of mercury [82,83]. Other metals that accumulate in fish organs are nickel and copper [80,84], causing significant damage to the fish species and its consumers. spreading across the Atlantic coast [85,86].…”

“…A study involving A. altiparanae showed that the level if DNA breaks was most sensitive biomarker to contamination with pesticides [79]. P. lineatus showed nickel accumulation in different tissues (kidneys, liver, gills and muscle) with DNA damage [80].Mining activities impact the aquatic ecosystem in the basins of Upper Paraguay and in the Colombian, Brazilian and Peruvian Amazon [6]. Mercury, the main compound released during gold mining, accumulates in the sediment and in the muscle and tissues of fish (bioaccumulation).…”

Neotropical fish correspond to approximately 30% of all fish species worldwide. The diversity of fish species found in Neotropical basins reflects variations in life-history strategies and exhibition of particular morphological, physiological and ecological attributes. These attributes are mainly related to different forms of feeding, life maintenance and reproduction. Today, fish populations are being threatened by anthropogenic actions that are having a visible impact on the natural state of continental aquatic ecosystems. The main causes are overfishing, non-native species introduction, reservoir-dam systems, mining, pollution and deforestation. The biology and population dynamics of the species are still unclear due to lack of research. Genetic tools can be useful resources for the conservation of Neotropical fish species in several ways. Molecular genetic markers are considered powerful tools to identify cryptic and hybrid fish and also allow the evaluation of the genetic variability and structure of populations of Neotropical ichthyofauna. Several analyses of molecular markers have been performed on Neotropical fish, including allozyme analysis, restriction fragment length polymorphisms in regions of DNA (RFLP), randomly amplified polymorphic DNA (AFLP), randomly amplified polymorphic DNA (RAPD), microsatellites, single nucleotide polymorphisms (SNPs) and mitochondrial DNA (mtDNA) markers. In order to analyse a high number of markers, next generation sequencing has allowed researchers to generate a large amount of genomic information that can be applied to the conservation of Neotropical fish.Keywords: molecular markers, genetic conservation, Neotropical ichthyofauna, overfishing, dam © 2018 The Author(s).

Rivers of the Neotropical regionThe distribution of freshwater fish around the world was mediated by historical climatic and geological events at different time points. Today, each global region has distinct patterns of distribution due to physical barriers obstructing species dispersion, representing different tolerances to environmental variables [1]. The tropics of the American continent are well known for their high biodiversity. This is due to habitat heterogeneity and a complex geological history. The Neotropical region is a biogeographic region that comprises Central America (including the southern part of Mexico and the peninsula of Baja California), the south of Florida, the Caribbean and South America. The origin and evolution of the Neotropical region arose through a process of synergism between its fauna that experienced local rainfall variations and gradual climate change resulting in a mosaic of habitats controlled by river migrations, sea-level fluctuations, local dryness and local uplifts [2,3].Regional geo...

“…Há diversas evidências na literatura do potencial tóxico do níquel. Em Oncorhynchus mykiss (TOPAL et al, 2017), Hypophthalmichthys molitrix (ATHIKE-SAVAN et al, 2006) e Prochilodus lineatus ( PALERMO et al, 2015) foram observadas alterações nos tecidos das brânquias, como espessamento lamelar, infiltração celular, fusão da segunda lamela, distorção, hipertrofia, hiperplasia e acumulação do metal nos tecidos.…”
