“…Muitos estudos confirmam que a NH 3 é a forma mais tóxica da amônia total (NH 4 1+ + NH 3 ) presente na água. Essa toxicidade é pela sua baixa capacidade de difusão por meio das membranas celulares, o que causa danos ao epitélio branquial e, consequentemente, Hurtado, Figueiredo, Costa, Bomfim, Queiroz e Pontes compromete os mecanismos osmorreguladores (DUTRA et al, 2016). Ainda de acordo com Kubitza (2003), valores de NH 3 acima de 0,20 mg.L -1 são suficientes para induzir toxicidade crônica e levar à diminuição do crescimento e tolerância dos peixes a doenças; entre 0,70 e 2,40 mg.L -1 podem ser letais e quando expostos frequentemente a concentrações de NH 3 acima de 0,02 mg.L -1 pode haver intensa irritação e inflamação nas brânquias.…”

A piscicultura é um dos segmentos da produção animal que mais cresce no cenário mundial; neste ramo a qualidade da água é preocupação constante, pois quando esta apresenta má qualidade causa problemas na produção e pouca lucratividade. Objetivou-se avaliar a qualidade da água com base em algumas variáveis limnológicas em viveiros de piscicultura de engorda de tambaqui (Colossoma macropomum) com abastecimento em disposição sequencial. Os resultados indicaram que o regime de chuvas e o manejo durante o ciclo de produção influenciaram os parâmetros avaliados. No universo temporal da pesquisa (ago./2013 a jul./2014), os valores de pH, amônia e nitrito estiveram de acordo com a resolução Conama 357/2005; a alcalinidade e temperatura estiveram dentro dos padrões indicados para piscicultura, o contrário para a maioria dos valores amostrados para o oxigênio dissolvido e fósforo total. Em ago./2013, mês dos menores índices pluviométricos na região, os viveiros apresentaram condutividade elétrica acima do estabelecido pela resolução Conama 357/2005; em out./2013 houve aumento expressivo da densidade da comunidade fitoplanctônica com florações pontuais, acarretando a menor transparência e oxigênio dissolvido em todos os viveiros. Os resultados indicam a necessidade de adoção sistemática de boas práticas de manejo a fim de melhorar a qualidade ambiental das criações, como também contribuir para a sustentabilidade da atividade aquícola.

“…Ammonia-N has been reported to cause a series of physiological reactions in crustaceans, including mainly behavioral reactions (Zimmer and Wood 2017), antioxidant response (Liang et al 2016;Pinto et al 2016), immune stress (Yue et al 2010), ion regulation (Romano and Zeng 2007), and ammonia excretion process (Wang et al 2003). Many studies have suggested also that a high concentration of ammonia-N can influence physiological response processes, such as moulting, growth and reproduction, and even lead to death (Chen and Kou 1992;Dutra et al 2016). Therefore, ammonia-N is now being increasingly considered as a main threat to crustaceans.…”

The swimming crab Portunus trituberculatus is an important farmed species in China. Ammonia-N represents a major physiological challenge for crab culture and the hepatopancreas plays a major role in physiological adaptation processes. To better understand the molecular mechanism of the crab in response to ammonia-N stress, we performed a transcriptome analysis in the hepatopancreas of P. trituberculatus challenged with ammonia-N stress (5 mg/L), using the high-throughput sequencing technology. In total, 52,280 unigenes were obtained from the hepatopancreas of P. trituberculatus, with an average length of 678 bp. Functional categorization and pathways showed some differentially expressed genes were involved in amino acid and nucleobase metabolism, energy metabolism, antioxidation, immune response, reproduction, moulting and material transport. The differential expression patterns of eight randomly selected annotated genes were validated by quantitative real-time PCR (qPCR). Results revealed a substantial number of genes modified by ammonia-N stress and a few significant ammonia acclimation pathways, which will serve as an invaluable resource for revealing the molecular basis of physiological adaptation mechanism in P. trituberculatus.

“…It is also a waste product of protein metabolism of fish and crustaceans and is not a persistent pollutant, such as metals or some organic compounds (Borgmann and Borgmann 1997). The accumulation of ammonia in the aquatic environment in intensive aquacultural systems as well as in the wild has been identified as one of the common causes of death in aquatic organisms (Cobo et al 2014;Dutra et al 2016;Ip et al 2001;Lin et al 1993;Xu et al 2004). Thus, it is important to know the tolerance to ammonia of aquatic species in order to assess its sensitivity and to improve the efficiency of aquacultural systems.…”

“…Several studies have demonstrated that the tolerance to ammonia increases with the ontogenetic developmental progress of the animals and decreases with exposure time (Dutra et al 2016;Liao et al 2011;Neil et al 2005;Ostrensky and Wasielesky 1995;Zhao et al 1997). The toxicity of waterborne ammonia to crustaceans has been studied by several authors in larval stages as well as juveniles and adults (Harris et al 2001;Hutchinson et al 1998;Liao et al 2011;Lin et al 1993;Marazza et al 1996;Moore et al 1997;Racotta and Hernández-Herrera 2000;Romano and Zeng 2010).…”

Effects of ammonia on zoea I of the Southern King Crab, Lithodes santolla (Decapoda, Lithodidae) were analyzed through acute (96 h) and chronic (29 days in total) assays (seven total ammonia nitrogen (TAN) concentrations: 9, 15, 25, 41, 67, 110, and 182 mg L-1 , plus control). The estimated LC 50-96 h was 107.97 mg TAN L-1 (1.93 mg NH 3-N L-1), while the safe level of ammonia was 10.79 mg TAN L-1 (0.19 mg NH 3-N L-1). Survival was highest in the three lowest ammonia concentrations throughout 96 h (93.3%, 90% and 93.3% in 9, 15 and 25 mg TAN L-1 , respectively). In chronic assays, the percentage of survival decreased along with the exposure time and the ammonia concentration. Zoeaes mean life time tended to increase almost gradually with the increment of ammonia concentration. Mean molting time from zoea I to II was 4.06 days, while it increased from zoea II to III, and zoea III to the post-larval stage (6.00 and 8.39 more days, respectively) with ammonia concentration. The percentage of individuals that have molted in every molt stage tended to decrease while ammonia concentration increased. Therefore, the results obtained in the present study bring new information about ammonia toxicity in early stages of development of crab Lithodes santolla, an important commercial species of the Beagle Channel.
