“…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).

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.

RESUMO:A contaminação dos ecossistemas aquáticos por substâncias químicas provenientes de atividades agrícolas inadequadas e do despejo irregular de efluentes tem se intensificado. Assim, é indispensável o uso de organismos que possam indicar a presença desses contaminantes ou a qualidade dos corpos hídricos. O objetivo do presente trabalho foi realizar uma revisão de bibliográfica sobre os aspectos gerais dos protistas ciliados ressaltando a importância da utilização desses organismos como bioindicadores em estudos de monitoramento de qualidade de água e em ensaios de ecotoxicidade com contaminantes aquáticos. De acordo com essa pesquisa, os protistas ciliados são excelentes organismos para serem utilizados como bioindicadores de qualidade de água em programas de monitoramento devido à sua abundância, ciclo de vida curto, sensibilidade às alterações físicas, químicas e biológicas no ambiente aquático, facilidade de manutenção em laboratório e prevalência em corpos hídricos. Os estudos com esses ciliados podem ser focados tanto em análises da diversidade, riqueza e abundância de espécies em ecossistemas aquáticos como em avaliações da ecotoxicidade de contaminantes que podem atingir corpos d´água. Nos estudos de monitoramento da qualidade de água que incluem determinação da riqueza, abundância e diversidade em ambientes impactos as espécies identificadas podem variar de uma região para outra, enquanto que em ensaios laboratoriais de toxicidade as espécies dos gêneros Tetrahymena e Paramecium são internacionalmente as mais utilizadas. PALAVRAS-CHAVE:Protozoários. Ecotoxicidade. Paramecium. Contaminantes.ABSTRACT: Contamination of aquatic ecosystems by chemicals from inadequate agricultural activities and irregular effluent disposal has intensified. Thus, the use of organisms that may indicate the presence of these contaminants or the quality of the water bodies is indispensable. The objective of the present paper was to perform a literature review on the general aspects of ciliate protists emphasizing the importance of using these organisms as bioindicators in water quality monitoring studies and in aquatic contaminant ecotoxicity tests. According to this research, ciliary protists are excellent organisms to be used as bioindicators of water quality in monitoring programs due to their abundance, short life cycle, sensitivity to physical, chemical and biological changes in the aquatic environment, ease of maintenance In laboratory and prevalence in water bodies. Studies with these ciliates can be focused on analyzes of the diversity, richness and abundance of species in aquatic ecosystems as well as evaluations of the ecotoxicity of contaminants that can reach bodies of water. In water quality monitoring studies that include determination of richness, abundance and diversity in impacted environments the identified species may vary from one region to another, whereas in laboratory toxicity tests the species of the genera Tetrahymena and Paramecium are internationally most used .

Azolla is a group of aquatic floating plants that can achieve very high growth rates compared to other aquatic macrophytes, with a doubling time of 2–5 days under optimal growing conditions. The ability of Azolla to grow at such rapid rates allows for the opportunity of utilizing it as a method to sequester a significant amount of atmospheric CO 2 in the form of biomass, which can be locked away to completely remove the carbon from the active carbon cycle, or which can be used in various applications such as animal feeds, biofertilizers, and biofuel production, which in turn will contribute to reduction in the fossil CO 2 emissions. In this desktop study, the potential use of Azolla for mitigating the annual increase in the atmospheric CO 2 levels was addressed, which were estimated at 18.9 billion tons of CO 2 per year. A theoretical setup of 1-ha ponds was assessed to estimate the total Azolla growing area required for counterbalancing the annual atmospheric CO 2 increase. Each 1-ha pond was found capable of capturing 21,266 kg of CO 2 (C) per year. The calculated required total area to mitigate the total annual increase was estimated to be 1,018,023 km 2 (equivalent to around a fifth of the Amazon forest area). Sensitivity analysis, which was based on the variations in the productivity of Azolla due to growing conditions, indicated that the required area would range between 763,518 and 1,527,036 km 2 . This study provides a novel natural method for CO 2 sequestration that has lower environmental impacts compared to conventional sequestration technologies as an alternative green approach for mitigating the effects of fossil fuels.
