O fator de condicao revelou que os bettas machos que passaram por periodos de privacao alimentar obtiveram melhores medias e com diferencas significativas (p<0,05)em relacao a exemplares que nao foram submetidos A restricao alimentar.
Estudos relacionados com ganho compensatorio apos periodos de privacao alimentar de peixe de producao para consumo sao bastante difundidos, entretanto, pesquisas envolvendo o manejo alimentar de peixes ornamentais e particularmente o Betta, sao incipientesdevido comportamento territorialista e agressivo (Dzieweczynski & Leopard, 2010), envolvendo maiores cuidados no manejo, o que aumenta muito o dispendio de trabalho para o arracoamento, pelas exigencias de ambientes individuais.
Estrategias de manejo de alimentacao que realizem curtos periodos de privacao de racao seguidos de posterior realimentacao ate a aparente saciedade, pode ser uma estrategia promissora para diminuir os custos de producao do cultivo de Betta splendens, minimizando os custos com mao de obra para o arracoamento e ofertando menores quantidades de racao melhorando o manejo em sistemas de cultivo com densidades de um individuo por unidade experimental.
Female Bettas were chosen because they typically have shorter fins than male Bettas, limiting the possibility of the Danios nipping at Betta fins (thereby compromising the health of the fish and the results of the experiment).
The results from Katie's 2012 experiment using Veiltail Betta fish are in.
8220;I admit; I was skeptical,” Katie told AquaNew in an interview when asked if she thought that a Betta raised in Watt-Ahh[R] could really grow measurably faster and larger.
Rhoad, Kalat, and Lopfer (1975) showed that the agonistic display in Bettas is more vigorous when they are presented with a male of the same species, followed by a mirror image, a moving model, and finally, a stationary model.
Twelve adult Bettas (Aqua Mundi, Bauru/SP) were used for this experiment, experimentally ingenuous, kept isolated in individual tanks (14 x 6 x 11 cm), with controlled lighting (12/12 hrs, cycle beginning at 7:00 a.
The aggressive display of the Betta splendens (Teleostei, Belontiidae) is very prominent, and Bronstein (1980, 1981a, 1982) suggested that it's reproductive and agonistic strategies are typical of many teleosts that utilize external fertilization in relation to the body of the female of the species.
To examine this type of behavior Bettas have been placed in containers separated by a glass partition, which allows the fish to see each other, and their responses are noted.
Male Bettas were obtained from several commercial sources.
Ideal fish for beginners are goldfish, danios, angelfish and colorful bettas.
