The objective of this study was to investigate the parasites occurrences and to determine the rates of infestation/parasitic infection in juvenile Arapaima gigas from seven fish farms in the state of Amazonas, relating to the characteristics of these fish farms. Of the 70 A. gigas evaluated, 43 were infested/infected, with a total of 133 parasites collected. Three fish farms (2, 4, 6) showed the highest levels of prevalence of parasites (100%, 70%, 70%), mean intensity (4.1±2.6, 8.1±9.2, and 2.1±1.3), and mean abundance (4.1±2.6, 5.7±8.1, and 1.5±1.5), respectively. Prevalence ranged from 30% to 100%, mean intensity from 1.0 to 8.1 and mean abundance from 0.3 to 5.7. Monogenea, Digenea, Nematoda (Hysterothylacium sp. and Spirocamallanus sp.) and Acanthocephala (Neoechinorhynchus sp. and Polyacanthorhynchus sp.) were identified. The parasites Hysterothylacium sp. and Neoechinorhynchus sp. were the most prevalent parasites with 31.43% and 15.71%, respectively. The fish presented negative allometry in growth and constant condition factor. Measures to prevent and control the parasitic diseases diagnosed are discussed as well prophylactic practices that contribute to the biosecurity of the farms. |

Chemicals, a class of global commodities, can be divided into inputs and end-use products, what can include a huge number of characteristics and applicability, encompassing organic and inorganic substances. From this perspective, the chemical industry plays a crucial role in most sectors of regional economies, which has led to innovative, life-enhancing products and technologies that not only support the global economy, but also help people live longer, healthier, more sustainable lives. The use of sustainable raw materials for feedstock of this industry as a transition for the circular economy is a challenge and an opportunity. In this way, sustainable carbonaceous materials (i.e., biomass, CO2, and recyclable materials) can contribute to the reduction of the negative environmental impacts from the chemistry exploitation. This perspective article, based-on scientific literature and market information, deals with an outlook of the chemical industry, the sources of its negative impacts on the environment, the industrial sources of sustainable carbonaceous materials, and the proposal of sustainable feedstocks in order to promote the sustainable development goals of the United Nations in chemistry. |
