Effects of starving and re-feeding strategies on the growth performance and physiological characteristics of the juvenile tongue sole (Cynoglossus semilaevis)

Effects of intermittent feeding on water quality, skin parasites, feed consumption, and growth performance of juvenile longfin yellowtailSeriola rivoliana(Valenciennes, 1833)

“…Partial compensation achieved in 48R2 could be explained due to the greater feed consumption (hyperphagia) and feed efficiency registered in this treatment group as suggested by Fang, Tian, and Dong (). According to our overall FE, fish exerted daily feed intake efficiently when they were fasted for short period up 48 hr.…”

“…During short periods of feed deprivation followed by ample feed supply, hyperphagic response may avert measurable growth depression, thereby, growth patterns between continuously fed and temporarily deprived fish might not be distinguishable (Ali et al, 2003;Eroldoğan et al, 2006;Thongprajukaew & Rodjaroen, 2017 (Morshedi et al, 2017;Shah et al, 2017). However, previous studies suggested that compensatory growth in fish could be a result of improved digestive enzymes activity during starvation/refeeding cycling (Yengkokpam et al, 2013); intermittent feeding schedule (Känkänen & Pirhonen, 2009;Thongprajukaew & Rodjaroen, 2017); the promotion of feed efficiency and digestibility coefficiency (Fang et al, 2017;Morshedi et al, 2017); and hyperphagia (Gao et al, 2015;Türkmen et al, 2012). As it is observed in length-weight relationship in our study, standard length also increased along with fish weight, but negatively related to fasting time.…”

“…Probably, the refeeding time (1 day) was not sufficient to trigger a compensatory response after 4 days of starvation. Fang et al (2017) stated that the degree of compensatory growth in Cynoglossus semilaevis juveniles depends on both, the length of feed deprivation and refeeding period. Likewise, stress conditions exerted from continuous starvation could lead into delayed growth and immune depression (Morshedi et al, 2017;Shah et al, 2017).…”

“…Up to date, mechanisms for compensatory responses are poorly understood in fish. However, previous studies suggested that compensatory growth in fish could be a result of improved digestive enzymes activity during starvation/refeeding cycling (Yengkokpam et al, 2013); intermittent feeding schedule (Känkänen & Pirhonen, 2009;Thongprajukaew & Rodjaroen, 2017); the promotion of feed efficiency and digestibility coefficiency (Fang et al, 2017;Morshedi et al, 2017); and hyperphagia (Gao et al, 2015;Türkmen et al, 2012).…”

“…). Probably, the refeeding time (1 day) was not sufficient to trigger a compensatory response after 4 days of starvation Fang et al (2017). Growth performance of fish fed once after 48 hr of starvation (48R1) exerted intermediate values.…”
