“…However, reference intervals for normal fish must be available, mainly due to the extent of physiological variation and the characteristics of each species and environment (RANZANI-PAIVA and SILVA-SOUZA, 2004;WEISS and WARDROP, 2010;BARBIERI and FERREIRA, 2011). In this study, haematological parameters were considered normal for the species, as described by FELDMAN et al (2000), and by BARROS et al (2009), in the same conditions and for the same species.…”

RESUMOO objetivo do estudo foi avaliar o efeito dietético dos fatores antinutricionais da SC (soja crua) na hematologia e no desempenho produtivo da tilápia-do-nilo (Oreochromis niloticus). Foi realizada a substituição de 0,0; 15,0; 25,0 e 35,0% da proteína do farelo de soja (FS) pela proteína da SC. Neste estudo, foram avaliados o efeito da substituição do FS por SC no perfil hematológico e desempenho produtivo da tilápia após 90 dias experimentais. Foi avaliado a atividade ureática da SC, indicando a presença de fatores antinutricionais. Os parâmetros hematológicos (eritrograma e serie branca do sangue) foram avaliados. Também foram avaliados os parâmetros de desempenho produtivo. A SC afetou o ganho de peso, o consumo de ração e a retenção proteica. Além disso, foram encontrados aumento do número de neutrófilos e diminuição da concentração de albumina. A inclusão de SC na dieta da tilápia alterou o número de células brancas no sangue e prejudicou o desenvolvimento produtivo. No entanto, nenhum efeito sobre eritrograma foi observado neste estudo. Assim podemos concluir que, embora os fatores antinutricionais presentes na SC interferiram no desempenho produtivo, recomenda-se utilizar o nível de substituição da SC abaixo de 35%, por não afetar a saúde dos peixes. ABSTRACTThis study was conducted to evaluate the effect of antinutritional factors of RSB (raw soybean) on hematology and growth performance of Nile tilapia (Oreochromis niloticus). The replacement was made the levels of 0.0, 15.0, 25.0 and 35.0% of the protein in soybean meal (SBM) by the crude soy protein. In this study, the effect of replacing SBM by RSB on haematological profile and growth performance of Nile tilapia were evaluated after 90 days of feeding. Urea activity was evaluated of RSB which indicated the presence of antinutritional factors. The hematological parameters (erythrogram and white blood cell) were evaluated. The parameters of growth performance were also evaluated. RSB affected the weight gain, feed intake and protein retention. Additionally, an increase of neuthrophils count and a decrease of albumin concentration were observed. RSB inclusion in the Nile tilapia diet changed the white blood cell number and negatively affected growth development. However, no effect on erythrogram was observed in this study. We can conclude that although the antinutritional factors present in RSB interfered the growth performance, it is recommended to use the replacement level of RSB below 35%, as it does not affect fish health.

“…Evaluation of oxygen consumption and ammonium excretion was used, for example, to study toxic effects caused by aromatic compounds (Lemaire et al 1996), heavy metals (Barbieri and Paes 2011), detergents (Barbieri et al 2002;Christiansen et al 1998), and a variety of toxicants (Boudou and Ribeyre 1989;Barbieri and Ferreira 2011). The purpose of the present study is to estimate ammonia toxicity, oxygen consumption, and ammonia excretion at salinity levels of 5, 20, and 35% at temperature 25°C, in Rachycentron canadum juveniles.…”

Juvenile cobia (Rachycentron canadum) (total length 15.16 ± 0.92 cm and weight 19.26 ± 4.5 g) were exposed to different concentrations of ammonia-N (unionized plus ionized ammonia as nitrogen), using the static renewal method at different salinity levels of 5, 20, and 35% at pH 8.1 and 25°C. The 24, 48, 72, 96 h LC 50 values of ammonia-N for R. canadum juveniles were 60.mg l -1 at 5%, respectively. The 24, 48, 72, 96 h LC 50 values of NH 3 -N (unionized ammonia as nitrogen) were 1.81, 1.46, 1.12, and 0.68 mg l -1 at 35%; 1.75, 1.49, 0.96, and 0.65 mg l -1 at 20%; and 1.52, 0.97, 0.71, and 0.31 mg l -1 at 5%, respectively. As the salinity decreased from 35 to 5%, susceptibility of ammonia-N increased by 34.5, 47.88, 50.56, and 64.23% after 24, 48, 72, and 96 h exposure, respectively. Furthermore, we found that exposure of fish to ammonia-N caused an increase in oxygen consumption of 129.1, 157.5, and 192% and a decrease in the ammonia excretion level of 53.4, 38.2, and 23.3% with respect to the control.

“…The irrigated paddy-fields, in their role as feeding places, may harm birds by virtue of the toxicity of the agricultural pesticides used in them Ferreira, 2011), which, after the prohibition of organochlorides (DDT) in 1985, came to include the now widely-used carbonates and organophosphates (Valdes, 2010). In this present study, 56 birds were found dead, possibly poisoned deliberately while they were foraging on the rice grains soaked in the carbofuran deposited on the dikes surrounding the plantations.…”

The assemblage of granivorous birds in the irrigated paddy-fields was evaluated over an annual cultivation cycle by means of 12 monthly samplings undertaken in each of 3 areas (of a total of 90 ha) in Itajaí, Santa Catarina, between August 2010 and July 2011. Of a total of 10 species, distributed among 5 families and 2 orders, Sturnella superciliaris (43.88%) and Sicalis flaveola (36.88%) were the most abundant. The regular species contributed with 45.17%, followed by the occasional (30.37%) and the seasonal (24.43%). Only the abundance of S. flaveola presented significant differences between the months of sampling (F11-33 = 7.1290, p < 0.01) as a result of the lower values recorded in December and January. The diversity and evenness indices showed similar fluctuation, with mean values ranging between 0.47 ± 1.37 and 0.29 ± 0.83, respectively. The average losses per hectare, due to the action of S. superciliaris and S. flaveola , were 8.35 ± 1.66 and 6.10 ± 1.48 kg of rice, equivalent to R$ 49.07 in the 3 areas monitored, giving a total average annual loss of 82.9 kg for the 90 ha of rice monitored.
