“…In rodents, the dominant phase I metabolic reaction for triazine pesticides is cytochrome P450-mediated N-dealkylation (Hanioka et al, 1999 a,b). Triazine pesticides have a direct effect on kidney structure and function in freshwater fish (Velisek et al, 2008(Velisek et al, , 2009b. In our experiment, the caudal kidney of carp with chronic exposure to simazine showed destruction of the tubules, although chronic exposure to terbutryn had no effect on caudal kidney.…”

“…During the laboratory toxicity test, common carp exposed to terbutryn and simazine showed normal feeding habits and exhibited no abnormal behaviour. Velisek et al (2009b) reported accelerated respiration and loss of movement coordination in rainbow trout and carp following acute poisoning with metribuzin. These characteristics have also been reported in Oreochromis niloticus and Chrysichthyes auratus (Hussein et al, 1996) and in Carassius auratus by Saglio & Trijasse (1998) following acute poisoning with atrazine.…”

“…Degeneration of hepatocytes has been described after exposure of bifenthrin and cyhalothrin (Velisek et al 2009a;Velisek et al 2009b;Richterova et al 2014), and damage of gill lamellae was de- scribed (Velisek et al 2006;Velisek et al 2009a). The concentration of 3.14 µg/l cypermethrin in the form of Alimethrine 10 EM was found to be associated with fatty degeneration of liver and severe teleangioectasiae of gills in juvenile rainbow trout (O. mykiss) (Velisek et al 2006).…”

ABSTRACT:The aim of this study was to assess the effects of Cyperkill 25 EC (a.i. cypermethrin 250 g/l) on cumulative mortality, growth indices, and ontogenetic development of embryos and larvae of common carp (Cyprinus carpio L.). An early-life stage toxicity test was used. Liver, intestine, kidneys, and gills of surviving larvae were examined, and the activity of the detoxifying and antioxidative enzymes glutathione reductase (GR), glutathione peroxidase (GPx), catalase (CAT), glutathione-S-transferase (GST), as well as lipid peroxidation (TBARS) was determined. Eggs of common carp 24 h post-fertilisation were exposed for 35 days to Cyperkill 25 EC at concentrations of 7.2, 36, 72, 144, and 360 μg/l containing the active ingredient cypermethrin at concentrations of 1.8, 9, 18, 36, and 90 μg/l, respectively. All larvae exposed to concentrations higher than 144 μg/l showed signs of damage after five days and died in the next two days; at concentrations of 72 and 36 μg/l total mortality was observed several days after hatching. Larvae exposed to 7.2 μg/l survived to the end of the test but showed significantly lower growth (P < 0.01) and retarded ontogenetic development compared to controls. Examination of these larvae did not reveal histological changes. Activity of GST, GR, and GPx in the exposed group was significantly lower (P < 0.01), while CAT and TBARS did not show significant differences from controls. Exposure to Cyperkill 25 EC affected hatching and survival at tested concentrations above 7.2 μg/l. Alterations in oxidative stress parameters and retarded growth and ontogenetic development were evident at 7.2 μg/l.

“…Estas observaciones coinciden con lo encontrado por otros autores para exposiciones agudas y subagudas de piretroides en peces (El-Sayed y Saad 2007, Velíšek et al 2009b). Es de resaltar que estas manifestaciones suelen ser irreversibles si el nivel de toxicidad supera el umbral máximo de exposición y acumulación (Herwig 1979).…”

Palabras clave: acuacultura, insecticidas, peces, CL50, dengue, ecotoxicología RESUMENLa tilapia Oreochromis niloticus es una especie de importancia en acuacultura con un desarrollo promisorio en la península de Yucatán. La bifentrina y la deltametrina son dos piretroides ampliamente utilizados por el sector salud en Yucatán para el control del mosquito Aedes aegypti, vector del dengue. Se evaluó la toxicidad aguda diferencial de Talstar® (sustancia activa, bifentrina) y Biothrine® (principio activo, deltametrina), en juveniles de tilapia O. niloticus. Se usaron ocho concentraciones de Talstar® (2.5 -400 µg/L) y ocho concentraciones de Biothrine® (0.56 -112 µg/L), más un testigo sin insecticida y tres repeticiones por tratamiento. Los signos de toxicidad en los peces bajo la influencia de ambos insecticidas fueron: nadadas erráticas, desbalance e hiperventilación, aunque resultaron más evidentes y en un menor tiempo de aparición, en las concentraciones más altas. El análisis probit reveló que la concentración letal media (CL50) de Talstar® fue de 75.11 µg/L a las 96 horas con intervalos de confianza (95 %) de 58.76 (inferior) y 96.34 (superior) µg/L. La CL50 de Biothrine® fue de 28.36 µg/L a las 96 horas, con intervalos de 23.29 y 35.27 µg/L. Estos valores son considerados como extremadamente tóxicos y alertan por el efecto contaminante potencial que podrían producir en ambientes naturales y de acuacultura. Es necesario continuar con la evaluación de los mecanismos de toxicidad de insecticidas que son utilizados en el sector salud para especies de importancia acuícola en México. Lo anterior por la perspectiva de continuar con su empleo y por el desarrollo del sector en la península de Yucatán.Key words: aquaculture, insecticides, fishes, LC50, dengue, ecotoxicology ABSTRACT Tilapia, Oreochromis niloticus is an aquacultural important species and both, bifenthrin and deltamethrin are two synthetic pyrethroids used by Health Services in Yucatán to control Aedes aegypti mosquito, dengue's vector.
