“…The species grouped in the main cluster (cluster 1) were generalists, as is common for small fishes (Pelicice & Agostinho 2006, Fiori et al 2016, or piscivorous such as Hoplias malabaricus (Rodrigues et al 2017). Prochilodus brevis, a specialist detritivore (mud eaters - Silva et al 2010), occurred only in the lower and middle reaches of the basin.…”

The Mamanguape River Basin is located in a peripheral semi-arid area of South America, with its headwaters and middle reaches running through the Caatinga (from wetter to drier) and its lower reaches through the Atlantic Forest. The objective of this study was to inventory the fish fauna of the Mamanguape river basin through a comprehensive sampling and to discuss its ichthyofaunal dominance pattern. Sampling was conducted between 2015 and 2016 at 38 points throughout. The main river course was sampled at 18 fixed points during two expeditions (dry and wet seasons) using traw nets, cast nets, and dip nets, with a standardized effort. The tributaries were sampled during the dry season at 20 points using an adaptaptation of the AquaRAP methodology. A total of 32 freshwater fish species belonging to 26 genera, 16 families and six orders were recorded, predominantly from the order Characiformes and the family Characidae. Astyanax fasciatus had widest distribution and greatest abundance in the basin. Siluriformes were the second most prevalent order, with five species recorded. Cichla cf. monoculus, Poecilia reticulata and Oreochromis niloticus were non-native records for the basin. Apareiodon davisi, an Endangered species, was recorded.

Na busca pelo conhecimento sobre sanidade de peixes a compreensão das interações ecológicas é fundamental, mas por um longo tempo houve negligência nos estudos sobre os parasitas que os afetam. Os trabalhos com patógenos de peixes no Estado do Maranhão ainda são insuficientes e por essa razão este trabalho vem com o objetivo de realizar um levantamento de pesquisas científicas desenvolvidas no período de 2010 a 2020 sobre os de patógenos em peixes de ambientes naturais e de cultivo deste estado. Utilizou-se como estratégias metodológicas a busca sistemática por artigos científicos nas plataformas Web of Science, Google Acadêmico, Pubmed, ASFA, Scopus e SciELO, no período compreendido entre 2010 a 2020, com o intuito de reunir informações sobre o tópico em estudo. Os resultados foram separados por categoria de agentes etiológicos pela diversidade de classes e técnicas distintas utilizadas nas pesquisas levantadas. Os dados obtidos evidenciam que os peixes podem ser acometidos por crustáceos ectoparasitas, bacterioses, nemátodas, protozoários, mixosporídeos, fungos, monogenóideas e vírus, porém no Maranhão as pesquisas com esses parasitas de peixes ainda são incipientes, neste sentido destaca-se a necessidade de mais estudos sobre sanidade de peixes nesta região. Além disso, estudos detalhados sobre o ciclo de vida dos parasitas e suas vias de transmissão com finalidade de prevenir as infecções, bem como a construção de um plano de ação com estratégias de tratamento, controle e prevenção dessas patologias serão de grande relevância em estudos futuros e ambientalmente sustentáveis.

“…In Brazil, Eustrongylides sp. larvae have been reported parasitizing H. malabaricus by several authors (Rego & Eiras, 1988;Rego & Vicente, 1988;Barros et al, 2007;Martins et al, 2009;Benigno et al, 2012;Meneguetti et al, 2013;Rodrigues et al, 2017;Kuraiem et al, 2020). Hoplias malabaricus is a predatory fish that feeds on a wide variety of other fish species and inhabits freshwater aquatic ecosystems in Central and South America (Godoy, 1975;Barros et al, 2007;Montenegro et al, 2013).…”

Fish consumption plays an important role in human diet. Hoplias malabaricus, commonly known as traíra, is a freshwater fish widely appreciated in several Brazilian states and frequently infected by Eustrongylides sp. fourth-instar larvae (L4). The aim of the present study was to evaluate allergenic potential of Eustrongylides sp. L4 crude extract (CEE). BALB/c mice were immunized intraperitoneally (IP) by 10 μg CEE with 2 mg of aluminum hydroxide on days 0 and 35. Specific IgG and IgE antibody levels were determined after immunization and cellular immunity was evaluated by assessing intradermal reaction in ear pavilion. Epicutaneous sensitization was performed in dorsal region by antigen exposure using a Finn-type chamber containing 50 μg of CEE or saline solution, followed by evaluation of specific antibody levels. IP immunization resulted in a gradual increase in IgG antibody levels and transitory IgE production. Significant increase in ear thickness was observed in cellular hypersensitivity reaction. In case of antigen exposure by epicutaneous route, CEE was able to induce meaningfully increased levels of specific IgG and IgE antibodies as well as heightened cellular immunity. Both intraperitoneal immunization and epicutaneous contact with Eustrongylides sp. larval antigens were observed for first time to be capable of inducing immunological sensitization in mice.
