- DIFFERENCES IN THE ACUTE AMMONIA TOXICITY BETWEEN SEXES OF GUPPY Poecilia reticulata (POECILIIDAE) Sandra Carla FORNECK Fabricio Martins DUTRA Rosânia Aparecida MALTAURO Almir Manoel CUNICO Biología toxicology ornamental fish nitrogen compound sexual dimorphism Lethal concentration This study evaluated the sensitivity of male and female of guppies (Poecilia reticulata) to ammonia. LC50-96h for males, females and combined sexes of P. reticulata was 37.33, 48.34, and 42.45 mg/L of total ammonia or 1.03, 1.34, and 1.17 mg/L of un-ionized ammonia. The mortality at the concentration of 40 mg/L of total ammonia differed between the sexes with higher mortality in males. These results have implications for production systems, since recommendations of ammonia toxicity reference values that do not consider the difference between the sexes, can lead to the mortality of males, and cause economic losses because males have higher commercial value in the ornamental market. 2023 artículo científico 0120-548X https://www.redalyc.org/articulo.oa?id=319079984007 https://www.redalyc.org/journal/3190/319079984007/ https://www.redalyc.org/journal/3190/319079984007/html/ https://www.redalyc.org/journal/3190/319079984007/319079984007.epub https://www.redalyc.org/journal/3190/319079984007/movil 10.15446/abc.v28n1.91052 en http://www.redalyc.org/revista.oa?id=3190 Acta Biológica Colombiana application/pdf Universidad Nacional de Colombia Acta Biológica Colombiana (Colombia) Num.1 Vol.28
