In order to investigate the effects of lysine and dissolved oxygen on grass carp, the grass carp were fed with 13, 15 and 17 g kg −1 lysine diet at about 6 mg L−1 (high dissolved oxygen, HO group) or 3.5 mg L−1 (low dissolved oxygen, LO group) dissolved oxygen level, for 8 weeks. The fish were fed to apparent satiation by hand. The results showed that apparent digestibility of protein, energy and dry matter were decreased significantly when grass carp were fed at 3.5 mg L−1 dissolved oxygen, and feed intake (FI) was also inhibited by low dissolved oxygen (P < 0.05). Weight gain, protein retention, protein efficiency, feed conversion ratio and amino acid retention of fish at 6 mg L−1 dissolved oxygen level were significantly improved at 3.5 mg L−1 dissolved oxygen level (P < 0.05). Weight gain, protein and amino acid retention, and feed efficiency of grass carp at the two dissolved oxygen levels were significantly improved by lysine supplementation (P < 0.05). The dietary lysine level and dissolved oxygen of water had an interaction effect on feed conversion ratios (P < 0.05). Grass carp fed at low dissolved oxygen level showed lower liver protein and fat contents. Plasma aspartate aminotransferase (AST) activity of grass carp fed at 3.5 mg L−1 dissolved oxygen level was significantly increased compared to 6 mg L−1 dissolved oxygen level (P < 0.05). Our results show that low dissolved oxygen level of water is harmful to the liver of grass carp.

“…The feed consumption in each tank was calculated by subtracting the weight of uneaten feed from the amount of feed presented (Thorarensen et al, 2010). Fish were handfed with commercial pellets containing 40% crude protein, 12% crude fat, 2.5% fibre, and 12% crude ash (Skretting-GISIS ® , Gye, Ecuador; size: 4 and 7 mm).…”

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

This study investigated the effect of intermittent feeding on the water quality, occurrence of skin parasites, feed consumption, and growth performance of juveniles (102.7 ± 5.1 g) longfin yellowtail, Seriola rivoliana. Fish were exposed for 89 days to six different feeding regimes: continuous daily feeding fed one or twice a day (treatment 24R1 and 24R2); 2-day fasting and refed once or twice a day for 1 day (treatment 48R1 and 48R2); and 3-day fasting and refed once or twice a day for 1 day (treatment 96R1 and 96R2). Water quality was not affected by feeding strategies. Likewise, condition factor was not affected by fasting up 48 hr. On the other hand, lowest survival in 96R1 was not related with abundance of skin parasites (Neobenedenia girellae). Specific growth rate, feed intake, feed efficiency, and morphological indices were not statistically different (p > 0.05) between 2 days fasted fish and continuously fed fish. Partial compensatory growth in 48R2 could be attributed to a hyperphagic consumption (8.2 ± 1.1 g day −1 fish −1 ) and feed conversion efficiency (0.61 ± 0.03). A feeding strategy based on cyclical 48 hr of starvation followed by 1 day of refeeding twice may be used for on-growing juvenile longfin yellowtail without reduction in growth or welfare of fish.

“…In addition, the flesh quality may be affected by stressful conditions during slaughtering of the fish . The ammonia and oxygen levels of the water are physicochemical parameters of great importance for fish survival and growth . The biological response to different concentrations of these compounds in the water varies widely among fish species.…”

“…The availability of oxygen in water can limit fish growth and performance in addition to inducing oxidative stress . To survive severe hypoxia or frequent anoxia, fish will preferentially use the anaerobic pathway of energy metabolism, which may lead to the formation of reactive oxygen species .…”
