“…O fornecimento de artêmia é largamente utilizado na larvicultura de peixes ornamentais devido ao seu alto valor biológico. Campelo et al (2020), ao avaliarem a utilização de artêmia, ração, infusório e uma combinação destes na alimentação do peixe ornamental acará servero, observaram maior comprimento total final e ganho em comprimento nos peixes alimentados com artêmia e com uma combinação de artêmia e ração extrusada. O maior ganho em peso também foi observado nos peixes que receberam artêmia como alimento exclusivo.…”

“…O fornecimento de alimento vivo é essencial para a sobrevivência de diversas espécies ornamentais, sendo o microcrustáceo Artemia sp. um dos alimentos vivos mais utilizados na larvicultura de peixes ornamentais por promover bons resultados zootécnicos, como os observados na produção de quinguio (Soares et al, 2000), acará-servero (Campelo et al, 2020), acará-bandeira (Pereira et al, 2016) e no Betta splendens (Couto et al, 2018).…”

A larvicultura é um período crítico na produção de peixes ornamentais, devido às necessidades produtivas e nutricionais das larvas nos primeiros dias de vida. O fornecimento de alimento vivo é essencial para a sobrevivência das larvas, sendo a Artemia sp. o alimento mais utilizando, apensar de representar custo elevado. Tornando necessária a busca por alimentos vivos de menor custo como o nematóide microverme da aveia. O presente trabalho foi desenvolvido com o objetivo de avaliar, por meio de índices de crescimento, desenvolvimento e sobrevivência, o fornecimento do microverme de forma exclusiva ou associado a artêmia e plâncton para larvas Betta splendens. As larvas alimentadas com microverme e artêmia apresentaram maior peso final, comprimento final, ganho em comprimento, maior taxa de desenvolvimento específico e sobrevivência. A taxa de uniformidade do lote no tratamento que recebeu apenas microverme não diferiu dos demais tratamentos, no entanto, as larvas submetidas ao regime alimentar com microverme e artêmia apresentaram melhor taxa de uniformidade quando comparas as que foram alimentadas com microverme e plâncton. A estratégia alimentar visando fornecer microverme e artêmia de forma conjunta promoveu os melhores índices de crescimento, desenvolvimento e sobrevivência na larvicultura inicial do peixe ornamental Betta splendens.

“…stands out for its ease of production and storage, in addition to its nutritional quality (Silva and Mendes 2006;Kestemont et al 2007). Fish fed Artemia nauplii in the first days of life have good growth rates and low mortality (Campelo et al 2020). However, it is important to control the daily food supply so that it can be used more efficiently by the post-larvae.…”

Effect of feeding frequency and water salinization on early development of Pyrrhulina brevis, an Amazonian ornamental fish

et al. 2023

Pyrrhulina brevis is an endemic fish from the Amazon basin that is valued in the ornamental fish market. In larviculture, fish are very sensitive to stressors and have a high mortality rate. Salinized water may provide more energy to overcome stress and feeding frequency is an important strategy to improve productive performance. Therefore, the aim of this study was to evaluate the best feeding frequency and the best level of water salinization for larval development of P. brevis. A total of 360 post-larvae of P. brevis (5.26 ± 1.65 mg, 5.57 ± 0.68 mm) were randomly distributed in 36 aquariums (1 L) in a 3x4 factorial scheme, to evaluate three concentrations of salt in water (0, 1 and 2 g L-1) and four feeding frequencies (once, twice, three and four times a day). We offered 150 Artemia nauplii per day and per post-larvae during 15 days. The fish kept at 1 g L-1 salinized water, and those fed 3 and 4 times a day presented significantly greater final length and weight, weight gain, and specific growth rate for length and weight. An interaction between salinized water and feeding frequency was observed for survival rate. We conclude that, during the initial rearing phase of P. brevis, feeding frequency of three times a day and salinized water at 1 g L-1 is recommended.

The present study aimed to assess the potential substitution of Artemia franciscana nauplii with Moina minuta neonates as the initial feed for angelfish (Pterophyllum scalare) and severum (Heros severus), evaluating the fish growth performance, live food cost, and intestinal histomorphometry. To achieve this goal, two separate experiments were carried out for each species during 20 days, using 200 postlarvae. Both experimental designs consisted of five treatments, namely, 100% A. franciscana nauplii (A100-M0); 75% A. franciscana nauplii and 25% M. minuta neonates (A75-M25); 50% A. franciscana nauplii and 50% M. minuta neonates (A50-M50); 25% A. franciscana nauplii and 75% M. minuta neonates (A25-M75); and 100% M. minuta neonates (A0-M100), with four replications (10 postlarvae per repetition). Angelfish postlarvae fed with A100-M0, A75-M25, A50-M50, and A25-M75 had better values of final length (13.31 mm, 14.15 mm, 13.32 mm, and 13.32 mm), gain in length (7.91 mm, 8.75 mm, 7.92 mm, and 7.92 mm), and length-specific growth rate (4.51% day−1, 4.82% day−1, 4.51% day−1, and 4.51% day−1). In the case of severum postlarvae, the highest length growth performance occurred in those fed with A100-M0 (15.86 mm, 8.90 mm, and 4.12% day−1), A75-M25 (15.45 mm, 8.49 mm, and 3.99% day−1), and A50-M50 (14.78 mm, 7.82 mm, and 3.76% day−1). Both species (angelfish and severum postlarvae) fed with A100-M0 and A75-M25 presented higher values of final weight (28.88 mg and 34.49 mg; 55.84 mg and 53.95 mg), gain in weight (27.56 mg and 33.08 mg; 51.03 mg and 49.14 mg), and weight-specific growth rate (15.42% day−1 and 16.30% day−1; 12.26% day−1 and 12.09% day−1). Live food cost for angelfish and severum postlarvae was higher in A100-M0 (US$ 0.92 and US$ 1.08) and lower for the ones in A0-M100 (US$ 0.36 and US$ 0.35). Severum postlarvae fed with A100-M0 (57.20 µm), A75-M25 (55.66 µm), and A50-M50 (54.27 µm) presented the highest intestinal villi heights. Thus, partial replacement of A. franciscana nauplii by M. minuta neonates in the proportion of A75-M25 or 100A-0M is viable and effective during the first feed of these fish species.
