“…This result suggested that mandarin fish could make better use of protein than grass carp in this condition. The ammonia‐N excretion was suggested as an index which might give some indication about mandarin fish culture, especially water quality management in intensive fish culture (Barbieri & Bondioli ), from the perspective of resource and environment‐friendly.…”

To understand the actual production of fish culture about the utilization of dietary protein and excreta impact on the environment between mandarin fish (Siniperca chuatsi) and grass carp (Ctenopharyngodon idellus), the study to investigate the effect of temperatures (19 AE 0.5°C, 24 AE 0.5°C and 29 AE 0.5°C) on ammonia-N excretion in mandarin fish and grass carp under fed and fasted states was conducted. These two species were fed a practical diet containing 325.2 g kg À1 crude protein at 3% body weight per day. The ammonia-N excretion rate was significantly increased when temperature increased from 19 to 29°C, and a linear relationship between ammonia-N excretion rate and temperature. The maximum ammonia-N excretion levels of mandarin fish and grass carp were observed at 4-8 h and 2-4 h after feeding, respectively, and the minimum values for both species were observed at 24 h after feeding. Under the feeding condition, mandarin fish had a lower ammonia-N excretion level compared to grass carp at 24°C and 29°C. The average amount of ammonia-N excreted by mandarin fish at 24 h is significantly higher than grass carp under fasting conditions, except 19 AE 0.5°C. These results indicated that mandarin fish might make better use of protein at higher temperature than grass carp when fed practical diets in commercial production. These results of this study suggested that mandarin fish had a lower ammonia-N excretion level compared with grass carp, making a less contribution to environmental loading in an intensive fish culture.

“…Haematological and serum protein profile has been used as a tool to evaluate fish welfare and disturbance on fish metabolism BARBIERI and BONDIOLI 2015). It can also be influenced by antinutritional factors, such as lectins presented in greater quantities in grain legumes, such as soybeans, peas and grasses.…”

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.

“…Generally, the increase in temperature in aquatic animals induces the higher toxic effects under toxicity exposure (Patra et al 2015), because the high temperature elevates the diffusion rate, bioavailability, and chemical reactions of the aquatic animals (Delos and Erickson 1999). Barbieri and Bondioli (2015) also reported the lower LC 50 for the ammonia exposure of Pacu fish, Piaractus mesopotamicus by increasing water temperature, which means that the higher temperature causes the higher ammonia toxicity.…”

Rockfish, Sebastes schlegelii (mean length 14.53 ± 1.14 cm and mean weight 38.36 ± 3.45 g), were exposed for 4 weeks with the different levels of ammonia in the concentrations of 0, 0.1, 0.5, and 1.0 mg/L at 19 and 24°C. The indicators of growth performance such as daily length gain, daily weight gain, condition factor, and hematosomatic index were significantly reduced by the ammonia exposure and high temperature. The ammonia exposure induced a significant decrease in hematological parameters, such as red blood cell (RBC) count, white blood cell (WBC) count, hemoglobin (Hb), and hematocrit (Ht), whose trend was more remarkable at 24°C. Mean corpuscular volume (MCV), mean corpuscular hemoglobin (MCH), and mean corpuscular hemoglobin concentration (MCHC) were also notably decreased by the ammonia exposure. Blood ammonia concentration was considerably increased by the ammonia concentration exposure. In the serum components, the glucose, glutamic oxalate transaminase (GOT), and glutamic pyruvate transaminase (GPT) were substantially increased by the ammonia exposure, whereas total protein was significantly decreased. But, the calcium and magnesium were not considerably changed.
