“…Data reported by Pereira et al 80 indicated an increase in the total leukocyte count in the species at 32°C compared to 26°C, after 60 days of exposure. At intervals between 20 and 40°C, however, the differential cell count indicate a decrease in the number of lymphocytes, and an increase in monocytes and neutrophils at 40°C, as well as a decrease in basophils 81 .…”

“…54,62 In relatively short experiments (up to 15 days), these variations are observed mainly for glucose levels at higher temperatures, which represents a stress-response strategy of the species to deal with stress. 79 Data reported by Pereira et al 80 indicated an increase in the total leukocyte count in the species at 32 C compared to 26 C, after 60 days of exposure. At intervals between 20 and 40 C, however, the differential cell count indicate a decrease in the number of lymphocytes, and an increase in monocytes and neutrophils at 40 C, as well as a decrease in basophils.…”

“…81 Thrombocytes numbers appeared to have an inverse relationship with the increase in temperature and exhibited lower counts under these conditions. 80 The occurrence and degree of parasitism are another factors to consider. The maintenance of tambaqui in an extreme scenario of climate change (A2) foreseen by the IPCC (2014) revealed that, regardless of the degree of parasitism, the counts of thrombocytes, total leukocytes, lymphocytes and monocytes increase, and that highly parasitised animals had a decreased neutrophil count.…”

In this study, we review the state of the knowledge regarding the thermal biology of tambaqui (Colossoma macropomum) with emphasis on reproductive, zootechnical, metabolic, physiological and molecular aspects, which may direct paths for new research. We observed an optimal range for performance of the species, since it grows and reproduces well between 25 and 32 C, though does not tolerate temperatures below 23 C. Temperatures above 30 C cause disturbances in the processes of reproduction and development of embryos and larvae of tambaqui. Its metabolism is influenced by the size of the animal, with greater oxygen consumption in smaller animals and at higher temperatures. Haematology is one of the most often investigated fields and shows an elevation of the analysed blood parameters according to elevation in temperature, which, above 35 C, seems to be harmful to animals. However, studies are needed that examine the relationships between temperature and nutritional aspects (protein, lipid and carbohydrate metabolism), the cellular responses, the relationship with other environmental parameters (pH, oxygen, dissolved organic carbon), pollutants, ionic regulation and excretion, aerobic metabolism, growth and reproduction under warm conditions (>32 C; +60 days). There is also the need to determine the thermal limits of the species as a function of different acclimation temperatures.

“…Os indicadores fisiológicos e comportamentais são frequentemente utilizados na avaliação dos impactos causados pelos agentes tóxicos nas populações (Guiloski et al, 2017;Szymańska et al, 2019;Gonzalez et al, 2021;Pereira et al, 2021;Salgado et al, 2021). Uma grande variedade de danos causados pelos agentes tóxicos pode ser observada nos organismos, como por exemplo, as alterações histológicas e morfológicas na estrutura óssea, no fígado, nos rins e em outros órgãos (Derakhsh et al, 2020;Matouke, 2019).…”

O aumento no consumo de medicamentos em todo mundo tem gerado vários estudos sobre os impactos causados pelo descarte inadequado de resíduos que contenham os princípios ativos dos medicamentos no meio ambiente. Após serem ingeridos, estes medicamentos são excretados na forma de outros compostos no esgoto doméstico, que vários ainda são persistentes no ambiente e geram alterações fisiológicas em organismos aquáticos. Devido ao crescimento populacional e o consumo excessivo, o anti-inflamatório conhecido como diclofenaco sódico, está entre os principais medicamentos encontrados nas águas superficiais brasileiras, em concentrações na faixa de micrograma por litro (µg.L-1). Este trabalho teve como objetivo estudar as alterações biomoleculares que o diclofenaco pode gerar em peixes da espécie Brycon opalinus, utilizando a técnica de Espectroscopia no infravermelho por transformada de Fourier (FTIR) acoplada aos métodos quimiométricos, a análise de componentes principais (PCA) e a análise de agrupamento hierárquico (HCA). Foram estudadas duas diferentes concentrações de diclofenaco mais o controle. O órgão selecionado para ser estudado foram as brânquias. Os resultados de PCA e HCA mostraram a discriminação entre os espectros de controle e tratados. A análise quantitativa através do cálculo das áreas das bandas de lipídios, proteínas e carboidratos mostrou alterações nestas biomoléculas, sendo que proteínas e carboidratos são mais sensíveis a exposição ao diclofenaco. Os resultados de deconvolução e ajuste de curvas mostraram a diminuição de estrutura desordenada e aumento de β folha da estrutura secundária de proteína para a exposição de 4,4 µg.L-1 de diclofenaco.
