“…nauplii obtain satisfactory results when given from the first feeding, promoting larval growth and development (Jomori et al., 2008; Leitão et al, 2011; Luz et al., 2011; Takata et al, 2014). This has been observed for the Amazon ornamental fish species Nannostomus beckfordi (Abe et al., 2019), Pyrrhulina brevis (Abe et al., 2016), Heros severus (Abe et al., 2018), Astronotus ocellatus (Jomori et al., 2013) and others, such as pacu Piaractus mesopotamicus (Jomori et al., 2012; Leitão et al., 2011; Portella et al., 2014), Rhinelepis aspera (Santos et al., 2012), Lophiosilurus alexandri (Santos et al., 2016), tambaqui Colossoma macropomum , matrinxã Brycon amazonicus (Barros et al, 2019) and piau Leporinus macrocephalus (Jomori et al., 2013). However, it is necessary to evaluate the capacity of fish larvae to adapt to this kind of live food, as it is not a natural food source of freshwater fish (Jomori et al., 2012).…”

The study tested the use of Artemia salina nauplii as first exogenous feeding in the larviculture of Hypancistrus sp. Moreover, we aimed to assess the quantity of prey concentrations and the stocking density during the first 30 days of feeding. Experiment I: larvae were fed with four initial prey concentrations, T100: 100, T200: 200, T300: 300 and T400: 400 A. salina nauplii/larvae/day. The quantity of A. salina nauplii increased every six days to adequate the larval growth. Experiment II: larvae were kept at four stocking densities, 1, 5, 10 and 15 larvae/L. In both experiments, the A. salina nauplii were consumed with success for the larvae. Best larvae growth and survival were observed with T400 in comparison to T100. In the Experiment II, the stocking density of 15 larvae/L showed higher ammonia (1.23 mg/L) and reduction of larvae growth and dissolved oxygen concentration (5.7 mg/L). The densities of 1 and 5 larvae/L provided the best results for growth. The stocking densities showed no differences for survival. Thus, we recommend the use of A. salina nauplii in the first feeding for larvae of Hypancistrus sp., at the initial prey concentration of 400 nauplii/larvae/day and stocking density of 5 larvae/L.

“…According to Abe, Dias, Reis, Couta, et al (2016), they also observed uniformity for weight 50% in larvae culture of ornamental fish Pyrrhulina brevis submitted to feeding rate four times a day. They claim that in specific stages of development greater aggressively and social behavior into shoal can influence its uniformity values.…”

“…During the larviculture of H. severus over different rate and feeding frequencies, according to Abe, Dias, Reis, Couta, et al (2016), the reduction of feeding frequency can cause the worst growth performance. They also not observed statistical difference of uniformity for weight or length showing different results when compared to the present study.…”

Summary Knowledge of the ideal feeding rate and feeding frequency for native species is important to improve the feed efficiency and reduce production costs. Thus, the present study evaluated feeding rate and feeding frequency effect for growth performance and health of Heros severus fingerlings. An experiment was carried out in completely randomized design with two feeding frequencies (2 and 4 times a day), three feeding rates (3%, 6% and 9% of body weight.day−1) and three replicates for 90 days. No differences were observed (p > 0.05) in the growth performance for fingerlings between two and four feeding frequencies, but lower feeding frequency (two times a day) caused lower uniformity for weight at the end of 90 days. Furthermore, the increase in the feeding rate from 3% to 6% or 9% (biomass.day−1) promoted higher weight and length gain, specific growth and length ratio (SGRL, SGRw) and biomass gain (p < 0.05). Lower feeding rate also caused blood change such as reduced values for glucose, triglyceride, erythrocyte, thrombocytes and leukocytes. Thus, H. severus fingerlings can be reared using feeding rate 6% (Biomass.day−1) with two meals a day for better utilization of the feed without affecting its hematological parameters.

IMPLICAÇÕES DE EXTRATO DE Erythrina crista-galli COMO ANSIOLÍTICO PARA Carassius auratus

Resumo A fitoterapia vem sendo utilizada em criação de peixes a fim de promover estabilidade no ambiente de cultivo e na profilaxia de doenças, contribuindo para a melhoria do bem-estar animal. Dentre os fitoterápicos, Erythrina crista-galli tem efeito sedativo e atividade antioxidante e antimicrobiana, além de funcionar como calmante natural. Na ausência de formulações para uso em peixes cultivados, surgem protocolos terapêuticos repletos de incertezas quanto à sua eficácia, ao impacto ambiental e ao perfil hematológico dos peixes. No ensaio de tolerância aguda da Erythrina crista-galli, foram utilizados exemplares de Carassius auratus, expostos às concentrações de controle (zero), 50, 100 e 200 mgL-1, com três repetições, por 96 horas. Foi observada a sobrevivência de 100% em todos os tratamentos. Estes resultados revelam que o extrato de Erythrina crista-galli não apresenta toxicidade para peixes. O balanço eletrolítico plasmático não apresentou mudanças. A utilização de até 100 mgL-1 não promoveu mudanças na trocas gasosas. O pH e a concentração de bicarbonato e glicose foram crescentes até a concentração de 100 mgL-1. Conclui-se que a utilização de Erythrina crista-galli para exposição aguda de Carassius auratus não promove mortalidade, mas provoca alterações indesejáveis nos parâmetros fisiológicos sanguíneos quando utilizadas doses acima de 100 mgL-1.
