PONTES, C. S. et al. Feeding frequency and growth performance of juvenile pink shrimp (Farfantepenaeus paulensis). Arq. Bras. Med. Vet. Zootec. [online]. 2015, vol.67, n.5, pp.1415-1420. ISSN 1678-4162.

It is generally believed that increasing feeding frequency has immediate benefits, including reduced nutrient leaching and increased shrimp growth. In this context, the aim this work was to evaluate the effect of feeding frequency in growth performance of Farfantepenaeus paulensis. Juveniles of Farfantepenaeus paulensis were grown for 30 days in pen enclosures, at a stocking density of 5 shrimp/m2. The shrimp were fed on feeding trays at a rate of 8% of their biomass per day, with treatments of one, two, three and four times per day, with four replicates each. The results showed no differences (5% probability) in biomass gain of F. paulensis when feed was offered two, three or four times per day. However, it was observed that the once a day frequency had a negative influence on weight gain for this species of shrimp. We conclude that the supply of food with 35% crude protein twice a day is sufficient for the growth of F paulensis. Feeding frequency of three or four times can provide increased spending in the cultivation of juveniles of this species.
