“…In the present study, fish spent long periods without food when temperature was maintained at 22 • C. Fasting in low temperatures was also demonstrated in other fish species (Sun et al, 2006;Oyugi et al, 2012;Wu et al, 2015). In L. alexandri, the large amount of visceral fat could be an energy resovoir on which animals draw during periods of fasting.…”

“…A temperatura pode ser um fator limitante na alimentação desses peixes, pois os peixes da região neotropical correspondem a sua atividade alimentar de acordo com o clima, sendo que o aumento da temperatura faz com que esses organismos obtenham maior ingestão (WU et al, 2015).…”

RESUMOEsse trabalho teve como objetivo avaliar os hábitos alimentares e maturação gonadal da espécie Rhamdia quelen na microbacia do rio Queima-Pé. Foram realizadas coletas nas quatro estações do ano outono, inverno, primavera de 2016 e verão de 2017. A análise da água indicou uma temperatura entre 24,8 ºC, máxima d e 39,4 ºC, mínima de 10,8 ºC, o pH teve média de 8,8 com variação entre 6,3 à 11 nas quatro estações, mostrando padrão ideal para sobrevivência da espécie. Em relação aos peixes examinados, foram dissecados 60 indivíduos, 29 fêmeas 30 machos e um não identificado. Sobre o estádio gonadal constatou-se que a desova de R. quelen é do tipo parcelada, sendo que as espécimes estavam no estádio A e B, (17 e 24 respectivamente), com o restante 8 no estádio C, 8 em D e nenhum em E. Sobre o grau de repleção os estômagos em sua maioria apresentaram estar meio cheio (Grau 2) em todas as estações. O hábito alimentar de Rhamdia quelen apresentou uma grande flexibilidade na sua dieta podendo ser classificada como insetívoro com tendência a detritívoro, consumindo principalmente, larvas de Simuliidae e restos de insetos, sendo que a maioria dos itens de sua preferência é de origem autóctones.

“…In addition, fish kept at 1, 2 and 6 times per day showed relatively low weight gain compared with that of fish fed 3-5 times per day, indicating that both low and high feeding frequencies could attenuate the growth rate of this species. Wu et al (2015) showed that feeding rare minnows…”

Optimal feeding strategies improve fish growth and health but may be affected by ammonia stress in closed rearing systems such as tanks or ponds. This study aimed to evaluate the effects of feeding frequency and ammonia levels in rearing water on the enzymes and genes involved in oxidative stress of yellow catfish. Experiment (ammonia exposure) and control groups were randomly assigned to one of three feeding frequencies (1, 2 and 4 times daily) for 8 weeks. Weight gain increased as feeding frequency increased from 1 to 4 times daily, but feed conversion ratio values decreased. The highest survival in ammonia group was found when fish was fed 2 times daily. Glutathione peroxidase activity and total antioxidant capacity in liver and brain of fish exposed to ammonia increased as feeding frequency increased from 1 to 4 times daily. Liver malondialdehyde content in control group decreased as feeding frequency increased from 1 to 4 times daily. The lowest liver malondialdehyde content in ammonia group was observed when fish was fed 2 times daily. Liver mRNA expression of superoxide dismutase and catalase in control group increased as feeding frequency increased from 1 to 4 times daily, but the highest superoxide dismutase and catalase expression in ammonia group were observed when fish were fed 2 times daily. This study indicates that higher feeding frequency of yellow catfish exposed to ammonia could result in oxidative stress and poor survival. The optimal feeding frequency of yellow catfish exposed to ammonia is 2 times daily.
