Effect of feeding frequency and feeding time on growth of Penaeus vannamei (Boone)

Abstract

Abstract. An intensive growth trial conducted In pens in an earthen pond indicated that growth of Penaeus vannamei (Boone) increased with feeding frequency and suggested that day feedings produce greater growth than night feedings. The differences in growth due to feeding frequency were significant, instantaneous growth rates (IGR) increasing from 1·62% to 1·66% to 1·71%/day as the number of feedings increased from one to two to four per 24 h. Comparison of the IGR of shrimp fed at night (1·64%/day) to that of shrimp fed during the day (1·68%/day) suggested (P= 0·0633) that growth was greater for shrimp given day feedings than for shrimp given night feedings. Survival of shrimp was not significantly different due to feeding frequency or due to time of feeding and averaged 74·7 ± 6·1%. Results indicate that P. vannamei cultured under conditions similar to those tested should be fed a minimum of four times daily and suggest that feeding during the day is at least as good as and may be preferable to feeding at night.

Influence of different dietary protein levels and feeding frequencies on growth performance and feed utilization of the Giant freshwater prawn, Macrobrachium rosenbergii with the Nile tilapia, Oreochromus niloticus in polyculture

“…Generally, studies on feeding frequency and its effect on shrimp growth are conflicting. Sedgwick (1979), Robertson et al (1993) and Tacon et al (2002) showed a positive effect on shrimp growth when feed frequency was increased. The present result also shows that feeding frequency has a great effect on growth performance and feed utilization of Nile tilapia fry.…”

Influencia de la alimentacion sobre el ritmo circadiano de las enzimas digestivas en el cultivo de juveniles de la langosta de agua dulce Cherax quadricarinatus (Parastacidae)

“…Los resultados sobre crecimiento en Litopenaeus vannamei realizados por Robertson et al (1993) sugieren que la alimentación durante las horas de luz, sería mejor que la alimentación nocturna. A su vez, Pontes & Arruda (2005) demostraron que L. vannamei accede a las bandejas de alimento e inicia un consumo rápido mostrando un mayor contenido en el tracto digestivo durante las horas de luz, por lo tanto estos resultados indican que el alimento debe ser ofrecido en la fase de luz, y en mayor proporción 7 h después del amanecer (Pontes et al, 2006).…”

Padrão de deslocamento do camarão marinho Litopenaeus vannamei (Boone) (Crustacea, Decapoda, Penaeidae) nas fases clara e escura ao longo de 24 horas

“…De uma maneira geral, as informações específicas sobre comportamento de peneídeos, encontradas na literatura, afirmam que a maioria das espécies possui sulco adrostral e apresentam padrão de atividade similar (ROBERTSON et al 1993). Tipicamente, são ativas durante a noite e se enterram durante o dia (HINDLEY 1975).…”
