Abstract

This study was designed to determine compensatory growth response of short-term starvation and refeeding cycles on Oreochromis mossambicus juveniles. A total of 360 juveniles were randomly divided into 12 tanks in triplicate groups. The control group (C) was fed three times a day to satiation. The feeding regimes of the other groups were designed as follows: 2 days deprivation /2 days refeeding (2DD2DRF), 2 days deprivation /3 days refeeding (2DD3DRF), and 2 days deprivation /4 days refeeding (2DD4DRF). After 60 days, only fish in 2DD4DRF group presented partial compensatory growth; no significant difference (P>0.05) was observed in the final weight (FW), and specific growth weight (SGR) compared to the control. Hepatosomatic index (HSI), viscerosomatic index (VSI), and condition factor (CF) was not affected by these feeding regimes. Furthermore, improved feed conversion ratio (FCR), and feed efficiency ratio (FER) were observed in 2DD4DRF fish, among groups. Feed intake (FI) was significantly lower (P<0.05) in starved fish compared to C. Meanwhile, muscle crude protein and lipid content in 2DD2DRF, and 2DD3DRF groups was significantly lower (P<0.05) compared to C and 2DD4DRF group. Compensatory growth response in 2DD4DRF presents possibilities for economic optimization in O. mossambicus production.

Effect of short‐term fasting and re‐feeding on growth, digestive enzyme activities and antioxidant defence in yellowfin seabream,Acanthopagrus latus(Houttuyn, 1782)

“…It seems that A. latus could conserve whole body biochemical composition during fasting period through physiological and biological means or it might recover nutrients during re-feeding phase suggesting adaptation of this species to short-term fasting periods and buffer its effect on body composition. Similar results also reported in rainbow trout, Oncorhynchus mykiss (Quinton & Blake, 1990), hybrid striped bass, M. chrysops × M. saxatilis (Turano, Borski, & Daniels, 2007), S. aurata (Eroldoğan, Suzer, et al, 2008;Eroldoğan, Tasbozan, et al, 2008), European sea bass (Adaklı & Taşbozan, 2015) Asian seabass, Lates calcarifer (Azodi, Nafisi, Morshedi, Modarresi, & Faghih-Ahmadani, 2016), and tilapia, Oreochromis mossambicus (Gabriel, Omoregi, Martin, Kukuri, & Shilombwelwa, 2018).…”

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

“…They listed several taxonomic distribution studies on teleost fish species that presented full, partial, over-compensation or the absence of compensatory growth. Similar results were achieved in gilthead seabream, (Sparus aurata) with 1-day feed deprivation and 2-days refeeding at satiation (Eroldoğan et al, 2006); juvenile tilapia, (O. mossambicus) subjected to 2 days deprivation and 4 days refeeding (Gabriel et al, 2018); and juvenile yellow mystus (Hemibagrus nemurus) fasted by 1, 2, and 4 days per week and fed ad libitum on the remaining days. In our findings, 48R2 fish achieved partial compensation.…”

“…According to the definition given by Ali et al (2003), in partial compensation, the deprived animals fail to achieve the same size at the same age as non-restricted contemporaries, but do show relatively rapid growth rates, and may have better feed conversion ratios during the re-feeding period. Similar results were achieved in gilthead seabream, (Sparus aurata) with 1-day feed deprivation and 2-days refeeding at satiation (Eroldoğan et al, 2006); juvenile tilapia, (O. mossambicus) subjected to 2 days deprivation and 4 days refeeding (Gabriel et al, 2018); and juvenile yellow mystus (Hemibagrus nemurus) fasted by 1, 2, and 4 days per week and fed ad libitum on the remaining days. However, in the same study, yellow mystus fasted for 3 days achieved fully compensatory growth (Thongprajukaew & Rodjaroen, 2017).…”

“…The 2-day fasting and 1-day refed fish was not affected. Likewise, no differences in condition factor during intermittent feeding with 48 hr of starvation in Coregonus lavaretus and O. mossambicus were observed, suggesting that compensatory mechanisms had taken place (Gabriel et al, 2018;Känkänen & Pirhonen, 2009).…”
