“…Similar strategies to those used in this experiment, using as a food source both inert and live food for the larvae stage, had already been successfully tested for different species by several authors (Liu et al, 2012;Fosse et al, 2013;Pradhan, et al, 2014), often being referred to as co-feeding.…”

“…Larvae subjected to treatments T5 and T6 (800 and 1,000 nauplii larva -1 , respectively), did not show a significant difference in the performance for the larvae of T4 (600 nauplii larva -1 ), but it was observed that from, approximately 383 nauplii larva -1 , there was an increase in the average cost per larvae. Several authors mention that the cost of living food in the early stages of fish production is a major problem faced by producers (Jomori, 2005;Ayres, 2006;Fosse et al, 2013) and the use of this food supply must be minimized in the culture whenever possible.…”

“…The use of a period of indoor larviculture requires knowledge of various issues related to diet and nutrition of the larvae, because the larvae will be fed exclusively from the food provided by humans. Over the years, several authors have developed and tested different feeding strategies on larval rearing phase (Charlon & Bergot, 1984;Fosse et al, 2013;Kamaszewski et al, 2014).…”

In order to optimize the performance and reduce costs in the larviculture of ornamental carp (Cyprinus carpio) in a recirculating aquaculture system, different feeding strategies were tested. For this, two experiments were carried out both under controlled conditions in a greenhouse, in a recirculating aquaculture system with a physical particle filter, biofilter, and filtering by ultra-violet irradiation. In the first experiment, measurements of Artemia nauplii were tested in the initial exogenous feeding of larvae at concentrations of 100, 200, 400, 600, 800 and 1,000 Artemia nauplii per larvae. In the following experiment, different protocols were tested for initial feeding for larvae. At this stage, were used: live food (Artemia nauplii) and inert (powder meal), used separately and simultaneously, and increases in the number of Artemia nauplii were also tested, offered at different times of cultivation. In the first experiment, the amount of 600 Artemia nauplii for larvae demonstrated to be the best option as it generated significant growth and the cost was less than that observed with the use of 800 and 1000 Artemia nauplii per larvae. The second experiment demonstrated that the feeding strategy with live food more commercial inert feed provided the best growth performance for ornamental carp larvae. The need to fix the amount of live food during the cultivation, probably due to the high specific growth rates observed during the larval stage also became evident.

“…Artemia nauplii has been used successfully as live feed during the intensive larviculture of freshwater species (PORTELLA and DABROWSKI, 2008;LUZ and SANTOS, 2010;JOMORI et al, 2012;PORTELLA et al, 2014), and also in Siamese fighting fish larval rearing (OGATA and KUROKURA, 2012;FOSSE et al, 2013). However, the lifetime of the Artemia nauplii in freshwater is reduced, and the use of low-salinity water may improve its lifetime (JOMORI et al, 2012), providing longer period of live prey exposure to the fish larvae.…”

The low-salinity water may improve live food utilization during larviculture, mainly when larvae are fed with salt water organisms. This study aimed to determine the median lethal concentration (LC 50 ) of NaCl in water for larvae of Betta splendens, an important ornamental species, and to evaluate the effect of low-salinity on the larviculture during the first 15 days of exogenous feeding. In the first experiment, 400 larvae were stocked in forty 250 mL aquariums, and exposed to ten saline concentrations. In the second experiment, 360 larvae were distributed in 24 1 L aquariums, in a factorial design 2x3 comprising two increasing prey densities, starting with 50 and 100 Artemia nauplii larva -1 , and three concentrations of NaCl (0, 2 and 4 g NaCl L -1 ). After 24, 48, 72 and 96 h of exposure, the LC 50 were 11.7, 10.1, 8.2 and 7.1 g NaCl L -1 , respectively. At the end of the experiment 2, larvae reared in salinity of 2 and 4 g NaCl L -1 and fed with the initial prey density of 100 nauplii larvae -1 were bigger and heavier. The use of low-saline water (2 to 4 g NaCl L -1 ) is a safe protocol for larviculture of Siamese fighting fish as it does not affect the survival and optimizes the use of Artemia nauplii when higher prey densities are used.

“…É possível identificar que a ausência do alimento vivo, sua substituição abrupta ou em períodos muito curtos, podem resultar na redução da sobrevivência durante a larvicultura (Lombardi e Gomes 2008;Fosse et al 2013), enquanto a utilização de alimentos vivos possibilitam melhores resultados de desempenho e sobrevivência (Luz e Zaniboni Filho 2001;Prieto et al 2006;Rocha et al 2008).…”

A larvicultura é uma das etapas mais críticas do desenvolvimento dos peixes e o seu sucesso está diretamente relacionado ao manejo alimentar, que pode proporcionar maiores sobrevivência e crescimento. Objetivou-se avaliar o tempo de transição alimentar e de fornecimento de meta-náuplios de Artemia spp. (MNA) na larvicultura do acará-bandeira. Dois experimentos foram conduzidos em delineamento inteiramente casualizado com cinco tratamentos e quatro repetições. Em cada experimento foram utilizados 540 peixes distribuídos em 20 aquários com 2 L. No primeiro experimento, avaliaram-se os períodos de transição alimentar (MNA + ração) por 1, 2, 3, 4 e 5 dias. No segundo experimento, avaliou-se o período de fornecimento de MNA por 5, 10, 15, 20 e 25 dias. Foram avaliados: ganho de peso, taxas de crescimento e desenvolvimento específico, sobrevivência e uniformidade do lote (apenas no experimento para avaliar o tempo de fornecimento de MNA). Não houve efeito significativo dos diferentes períodos de transição alimentar sobre as variáveis de crescimento (p>0,05), porém a sobrevivência foi maior (p<0,05) nos tratamentos compostos por 3, 4 e 5 dias de alimentação conjunta. Em relação ao tempo de fornecimento de MNA, foram observados piores resultados (p<0,05) quando o tempo de fornecimento do alimento vivo foi menor (5, 10 e 15 dias). Os animais que foram alimentados com MNA antes da transição alimentar, por mais tempo (20 e 25 dias), apresentaram os melhores resultados de crescimento (p<0,05). Portanto, recomenda-se uma transição alimentar de três dias e um fornecimento de MNA por 20 dias para realizar a substituição total do alimento vivo pela ração. PALAVRAS-CHAVE: Alimentação, peixe ornamental, ração, sobrevivência. Different feeding strategies on larval rearing of angelfish (Peterolophyllum scalare, Cichlidae) ABSTRACTThe hatchery is one of the most critical stages of the development of fish and their success is directly related to food handling that can provide greater survival and growth. The aim of this study was to evaluate the time of dietary transition and providing meta-nauplii of Artemia spp. (MNA) for the angelfish larvae. Two experiments were conducted in a completely randomized design with five treatments and four repetitions. On each experiment there were used 540 fishes, distributed in 20 tanks with 2 liters each. In the first experiment, there were evaluated the dietary transition periods (MNA + Diet) for 1, 2, 3, 4 and 5 days. In the second experiment, there were evaluated the supply of MNA for 5, 10, 15, 20 and 25 days. There were evaluated: weight gain, growth rate and specific development, survival and batch uniformity (only in the experiment to evaluate the time of fish feed with MNA). There was no significant effect of different periods of dietary transition on the growth variables (p>0.05), but survival was higher (p<0.05) in the treatments composed of 3, 4 and 5 days of joint feed. In relation to the time of supply of MNA worse results were observed (p<0.05) when the time of supply of live food was...
