Feeding Frequency Effects on Water Quality and Growth of Walleye Fingerlings in Intensive Culture

Effect of feeding frequency on growth and size variation in juvenile pikeperch, Sander lucioperca (L.)

“…But in this study significant differences between the groups were noted in the growth rate, condition, and chemical composition of the fish, no differences were determined in the final Cv BW coefficient (Zakęś et al, 2003). The feeding frequency was not found to have a significant effect on the values of the body weight variability coefficient in walleye (3 to 30 feed rations daily; BW = 28.2 g; Phillips et al, 1998) or in Atlantic salmon fed at frequencies of 3, 9 or 27 rations daily (average BW depended on the experiment -225-1 218 g; Thomassen and Fjaera, 1996). It should be emphasized that in the present study the coefficient of body weight variability was highly differentiated in the replication of each experimental group.…”

“…Thus, it can be assumed that the applied feeding schedule met the nutritional requirements of juvenile pikeperch. Studies of walleye (Phillips et al, 1998), Atlantic sturgeon, Acipenser oxyrinchus (Giberson and Litvak, 2003), and sunfish hybrids (female green sunfish, Lepomis cyanellus × male bluegill, L. macrochirus) (Wang et al, 1998) also showed that the feeding frequency did not affect the feed conversion ratio.…”

“…The effect of feeding frequency is not only species specific; it also depends on the given developmental stage (size) of the fish (Folkvord and Otterå, 1993;Linnér and Brännäs, 2001;Giberson and Litvak, 2003). In intensive rearing, particularly in recirculating systems, feeding frequency may influence fish growth both directly and indirectly as it can affect water quality and oxygen and ammonia concentrations (Phillips et al, 1998).…”

Growth and Production of Monosex Tilapia (Oreochromis niloticus) Under Different Feeding Frequencies in Pond Conditons

“…The significantly (P˂0.01) highest fish production was 62.42 kg/dec/4 months in T 1 and production was found to be decreased significantly with the decrease in feeding frequencies. The lowest fish production was 45.33 kg/dec/4 months in T 3 . The result of the present study demonstrated that four times feeding frequency played better effect on the growth and production performance of monosex male tilapia (Oreochromis niloticus).…”

“…However, to improve fish culture at commercial level, it is important to establish an appropriate feeding management strategy that is based on identification of the daily feeding patterns or rhythms [3][4]. It is well known that the amount and timing of feeding play an important role in growth and feed utilization efficiency [5][6][7][8].In aquaculture, like other form of husbandry, feeding is crucial for its viability and success [9].…”
