“…Siamese fighting fish is one of the most studied ornamental fish species in the scientific literature being used as a fish model in physiological and behavioral studies (Haller;Wittenberger, 1988;Dzieweczynski;Lyman;Poor, 2009;Puello-Cruz et al, 2010). Additionally, this fish is one of the most common species used as pets and which hobbits have been using to develop new varieties for the ornamental fish market.…”

The expansion in the market of ornamental fish depends on the intensification of production systems and the generation of appropriate technologies. Therefore, it is necessary to know the nutritional requirements of each species for the formulation of nutritionally balanced diets. A 30-day feeding trial was undertaken to evaluate the effects of different dietary digestible protein to energy ratio in diets for Betta splendens fingerlings. Fifty-six all-male B. splendens with 1.03 ± 0.11 g average weight were randomly stocked into 56 1L-aquaria in a completely randomized design with a 2 x 4 factorial arrangement, comprising eight treatments and seven replication. Each fish was considered an experimental unit. Diets were formulated to contain 28.0, 35.0, 42.0 and 49.0% DP and 3,600 and 3,200 kcal/kg DE. The growth parameters evaluated in this trial were weight gain (WG), feed intake (FI), feed conversion ratio (FCR), protein efficiency ratio (PER) and specific growth rate (SGR). No difference (P > 0.05) was observed for WG, FCR and SGR. However, a higher FI was observed for fish fed diets containing 42.0% DP (P < 0.05). A positive effect of DP and DE on PER was observed in this study. Generally, according to the increase of DE levels, a reduction on PER was observed. Based on this experimental condition, we recommend the use of 28.0% DP and 3,200 kcal/kg DE in diets for B. splendens.

RESUMOA expansão no setor produtivo de peixes ornamentais depende da intensificação dos sistemas de produção e da geração de tecnologias adequadas. Por isso, é necessário o conhecimento das exigências nutricionais de cada espécie para a formulação de rações nutricionalmente adequadas. Neste estudo, objetivou-se avaliar as diferentes relações energia:proteína digestível em dietas para alevinos de Betta splendens. O experimento teve a duração de 30 dias, sendo utilizados 56 alevinos machos de B. splendens com peso médio inicial de 1,03 ± 0,11 g. O delineamento experimental utilizado foi o inteiramente casualisado em arranjo fatorial, sendo composto por oito tratamentos e sete repetições, considerando-se um peixe como uma unidade experimental. Foram formuladas dietas práticas, cujos níveis de proteína digestível foram 28,0; 35,0; 42,0 e 49% e os níveis de energia digestível de 3.200 e 3.600 kcal/kg. Os parâmetros de desempenho produtivo avaliados foram: ganho em peso (GP), consumo de ração aparente (CRA), conversão alimentar aparente (CAA), taxa de eficiência protéica (TEP) e taxa de crescimento especifico (TCE). Não houve diferença significativa entre os tratamentos para GP, CAA, TCE, entretanto foi observado maior CRA para o nível de PD de 42% (P<0,05). A TEP apresentou diferença significativa, de maneira que quanto maior o nível de energia digestível menor a taxa de eficiência protéica. Com base nas condições experimentais deste estudo e na taxa de eficiência protéica, o melhor nível de PD e ED para melhor taxa de eficiência protéi...

“…The use of slightly saline water is an alternative method to freshwater. The addition of salt to freshwater can extend the Artemia nauplii lifetime (Beux and Zaniboni Filho 2006), prevent the occurrence of some fish diseases (Altinok and Grizzle 2001b; Puello‐Cruz et al 2010) and reduce stress and the osmotic differences between the animal and the external environment (Wurts 1995; Baldisserotto 2009). Larviculture in slightly saline water has been studied with various neotropical freshwater species (Luz and Portella 2002; Weingartner and Zaniboni Filho 2004; Beux and Zaniboni Filho 2007; Santos and Luz 2009).…”

The aim of this study was to evaluate the growth and survival of pacu, Piaractus mesopotamicus, larvae reared in different salinities and to determine the Artemia nauplii life span in freshwater and in saline water. First feeding 5‐d‐old pacu larvae were reared in freshwater or at 2, 4, 6, 8, 10, 12, and 14 ppt salinities. The larvae were reared in 1.5‐L aquaria at a density of 10 larvae/L with three replicates per treatment. After 10 d of rearing, significant differences (P < 0.05) were observed for growth and survival. Larval growth was higher at 2 and 4 ppt, and survival at 2 ppt was 100%. In freshwater and at 4, 6 and 8 ppt, the survival was 91.1, 93.3, 73.3, and 39.9%, respectively. At higher salinities, there was 100% mortality after 2 h (12 and 14 ppt) and 8 h (10 ppt) of exposure. The slightly saline water of at least 2 ppt increased the Artemia nauplii life span compared to the life span in freshwater. Later, in a second trial, 5‐d‐old pacu larvae were reared in freshwater and at 2 and 4 ppt salinities during the first 5 or 10 d of active feeding, and then the fish were transferred to freshwater. At the end of 15 d, larval growth was lower in freshwater (42 mg) than in treatments 2 and 4 ppt (59–63 mg). The abrupt transfer of fish from freshwater to slightly saline water and the return to freshwater did not affect the survival rates (89–97%). The larvae were able to adapt to these saline environments and handle abrupt changes in salt concentration. We concluded that salinity concentration of 2 ppt can be used for pacu larval rearing, allowing the Artemia nauplii lifetime to last longer and cause faster fish growth.

“…In terms of the rearing of larvae of Betta sp., it has been reported that infusorians are common as the first food because of the small size of the mouth of the larvae. Very few other rearing techniques have been reported, and infusorians have retained their popularity among the commercial breeders [12]. Even though infusorians are most commonly used as the first food for Betta sp.…”

Larvae of the Siamese fighting fish Betta splendens were reared on the mass-cultured small freshwater rotifer Brachionus angularis Laos strain (UTACLao), Paramecia sp., and Artemia as live food sources. Larvae fed live food were found to have a significantly high survival rate (97.5-100%) 18 days after hatch (DAH) in comparison to the control unfed larvae, which died by 12 DAH. Rotifer-fed larvae were found to grow faster than paramecia-fed larvae. The fastest growth rate was observed in larvae fed a combination of rotifer and Artemia, with growth in these larvae increasing by 282% by 18 DAH [total length (TL) 11.3 ± 1.2 mm] relative to body measurements taken 3 DAH. The next fastest growth rate was observed in rotifer-fed larvae, with a 158% increase in growth observed by 18 DAH (TL 7.6 ± 0.5 mm). The paramecia-fed larvae were found to grow by only 54.3% (TL 4.6 ± 0.1 mm) during the same period.
