“…Other research based on the measurements of Cytochrome P4501A (CYP1A) induction in trouts showed that the exposition to surfactant-based dispersants (Corexit 9500) caused increase of the effects of crude oil hydrocarbons (Ramachandran et al, 2004). Recently, the ecotoxicological evaluation of commercial surfactants to fish jewel tetra (Hyphessobrycon eques) provided LC 50 values ranging from 2.34 to 34.95 mg/L after 96 h exposition (Carraschi et al, 2011).…”

“…Estudos demonstraram efeitos tóxicos do formol em peixes, como agressão do epitélio branquial (Martins 2004), também há relatos que a toxicidade aumenta com a elevação da temperatura da água (Carraschi et al 2011) sendo esta afirmação muito importante para a realização de tratamentos em peixes tropicais. Para o sulfato de cobre é reportado que o mesmo é tóxico em água com baixa dureza e seu uso prolongado pode deixar os peixes debilitados (Bassleer 2011) além de que no ambiente natural já ocorrem problemas relacionados com o aumento da sua concentração nos corpos de água ocasionando efeitos tóxicos nos organismos aquáticos (Mazon et al 2002).…”

RESUMOO objetivo deste trabalho foi avaliar a eficácia da formalina e sulfato de cobre no controle de monogenéticos em juvenis de Hemigrammus sp e seu efeito na contagem diferencial de leucócitos. Utilizou-se um delineamento inteiramente casualizado com 5 tratamentos e 3 repetições. Todos os tratamentos tiveram duração de três dias e corresponderam a: T1, controle; T2 e T3 banho por imersão de uma hora em formalina, em duas concentrações uma de 0,25 ml e outra 0,1 ml formalina L ). Após o período experimental observou-se que em T2 ocorreu 100% de mortalidade. O T3 e T5 proporcionaram eficácia de 100%, porém os peixes apresentaram intoxicação e mortalidades de 66 e 80%, respectivamente. T4 apresentou eficácia de 77,7% e diminuição dos índices parasitológicos: número total de parasitos de 11,3±9, intensidade média de infecção de 3,2±2 e prevalência de 47,1%. Quanto aos leucócitos observou-se que no T3, T4 e T5 ocorreram diferenças na proporção de linfócitos, monócitos e neutrófilos em relação ao controle. O CuSO 4 e a formalina reduzem a carga parasitária, mas apresentaram-se tóxicos nas maiores concentrações. PALAVRAS-CHAVE: CuSO 4 , formol, monogênias, tratamento Evaluation of formalin and copper sulfate on monogenetic parasite (Urocleidoides sp.) of Hemigrammus sp. (Osteichthyes: Characidae) juveniles ABSTRACTThe objective of this study was to evaluate the effectiveness of formalin and copper sulphate to control monogeneans in juvenile Hemigrammus sp and its effect on leukocyte count. We used a completely randomized design with five treatments and three replications. All treatments lasted for three days and consisted of: T1, control; T2 and T3 immersion bath for one hour in formalin, an of two concentrations of 0.25 ml formalin and the other 0.1 ml L ). After the experimental period was observed that T2, 100% mortality. The T3 and T5 provided 100% efficiency, however, fish presented mortalities and intoxication of the 66 and 80% respectively. T4 showed an efficacy of 77.7% and decrease in parasitological indices: total number of parasites of11, 3 ± 9, mean infection intensity of 3.2 ± 2 and a prevalence of 47.1%. As the leukocytes was observed that at T3, T4 and T5 occurred differences in the proportion of lymphocytes, monocytes and neutrophils as compared to control. The CuSO 4 and formalin reduce the parasite load, but presented to be toxic at higher concentrations.

“…Regarding water quality parameters under experimental conditions or during production, there are reports of temperatures ranging from 20 °C (Santos et al, 2017) to 28.5 °C (Park et al, 2014), slightly acidic or even neutral pH (Carvalho & Del-Claro, 2004;Park et al, 2014;Silva et al, 2014;Berchielli-Morais et al, 2015;Silva et al, 2015;Marcon et al, 2016;Silva et al, 2016;Santos et al, 2017;Mansano et al, 2018;Miraldo & Pecora, 2017;Çelik & Cirik, 2019), and dissolved oxygen above 5.0 mg L -1 (Wang et al, 2006;Sotero-Santos et al, 2007;Pan et al, 2010;Carraschi et al, 2011;Pan et al, 2011;Aguinaga et al, 2014;Park et al, 2014;Silva et al, 2014;Berchielli-Morais et al, 2015;Silva et al, 2015;Marcon et al, 2016;Santos et al, 2017;Miraldo & Pecora, 2017). It should be noted that the conditions maintained in the experiments or in the cultivation of the species are similar to those observed in natural environments.…”

Hyphessobrycon eques has a great prominence in fishkeeping and scientific research. In this context, a systematic literature review was performed to assist in the improvement of captive breeding of this species and to identify knowledge gaps. Notably, of the 966 articles published between 1997 and 2020 found in an initial screening of the digital libraries of Google Scholar, PubMed, SciELO, Science Direct, and Scopus, only 56 represented research on the species according to the established criteria. Considering aspects pertinent to captive reproduction, 25 studies were selected. These studies addressed information regarding reproduction; embryonic, larval, and juvenile development of the species; parasitic fauna; limiting concentrations of prophylactic agents; food preferences; and dietary supplements already used for these fish. Only seven studies reported information on the physicochemical characteristics of water in natural habitats, with great variations in several parameters, mainly those related to temperature. In 5 of the 25 selected studies, information related to reproductive characteristics and/or embryonic, larval, and juvenile development was addressed. However, only two studies developed experimental studies with information relevant to the captive breeding of the species. Studies to identify parasitic fauna and to analyze the use of prophylactic agents were also found. As for the information gaps on the cultivation of the species, there are no studies related to nutrition seeking to determine the species nutritional needs, including feeding frequencies, feeding durations, and specific amounts of food. Therefore, this review offers a great support for the breeding of H. eques by highlighting opportunities for new scientific studies that could enrich and collaborate in the breeding of this ornamental fish.
