“…Minimization of the amount of feeding may have the effect not only of reducing the cost of feeding but also the biological loading of recirculation systems and effluent production in flow-through systems (Woods 2005). Several studies have been conducted on the effects of manipulating feeding regimes for several cultured fish species to improve culture efficiency (Brett and Shelbourn 1975;Huisman 1976;De Silva et al 1986;Chiu et al 1987;Storebakken and Austreng 1987a, b;Xie and Sun 1992;Ross et al 1992;Cui et al 1994;Ryer and Olla 1996;Xie et al 1997;Wang et al 1998;Saether and Jobling 1999;Rabe and Brown 2000;Lupatsch et al 2001;Mihelakakis et al 2001;Dwyer et al 2002;Cho et al 2003;Johnston et al 2003;Al-Hafedh and Ali 2004;Sogard and Spencer 2004;Han et al 2004;, Berrill et al 2006Du et al 2006). As the culture of Indian major carp, rohu, Labeo rohita, becomes more intensive, strategies for supplementary feeding will have to be assessed to reap maximum economic returns.…”

An eight-week feeding trial has been conducted to determine the optimum ration for Indian major carp, Labeo rohita, fingerling (4.10 ± 0.30 cm, 0.55 ± 0.16 g) by feeding a purified diet (40% CP; 3.61 kcal g -1 GE) at six levels, 2, 4, 6, 8, 10, and 12% of body weight per day, at 0800 and 1600 h, in triplicate, to 20 fish per trough fitted with a water flow-through system. Highest weight gain, best feed conversion ratio (FCR), best specific growth rate (SGR%), and highest protein efficiency ratio (PER) were evident for rations of 6-8% body weight. Second-degree polynomial regression analysis for FCR, PER, protein, and energy retention data indicated the break-points occurred at 6.55, 6.75, 6.80, and 6.95% bw per day, respectively. Significant (P < 0.05) differences between body composition were observed for fish fed different rations. Maximum body protein content was recorded for 6% and 8% rations. A linear increase in body fat content was evident with increasing ration.Body moisture and ash content remained nonsignificantly (P > 0.05) low for higher rations, however. On the basis of these results it is recommended that feeding in the range 6.5-7.0% bw per day corresponding to 2.6-2.8 g protein and 23.49-25.31 kcal energy per 100 g of the diet per day is optimum for growth and efficient feed utilization of Labeo rohita. Results for 2-4% rations (0.8-1.6 g protein and 7.23-14.46 kcal energy) suggest these amounts approximate to the maintenance requirement of this fish.

“…Although the Nile tilapia is a well-known species of fish, which is frequently used in physiology studies (Ross et al 1992;McKenzie et al 1996;Xie et al 1997;Gaye-Siessegger et al 2007), its physiological and behavioral responses to starvation remain unknown. Nile tilapia have rather high energy expenditure and feeding frequency by comparison with other fish (Xie et al 1997).…”

The resting metabolic rate (MO 2rest ) of juvenile Nile tilapia (Oreochromis niloticus) decreased from 264.5 to 189.4 mg O 2 kg À1 h À1 after one week of starvation and the maximum post-exercise oxygen consumption (MO 2peak ) decreased from 1032.5 to 647.4 mg O 2 kg À1 h À1 . MO 2rest and MO 2peak decreased further to 166.5 and 463.3 mg O 2 kg À1 h À1 respectively after six weeks of starvation. Furthermore, the duration of the excess post-exercise oxygen consumption (EPOC) decreased from 113.3 to 56.3 min, and the magnitude of EPOC decreased from 276.8 to 100.2 mg O 2 kg À1 . We conclude that tilapia are very sensitive to food shortage and rapidly reduce their energy expenditure. The decreased metabolic scope and EPOC imply that both aerobic and anaerobic metabolic capacities are reduced in starved tilapia, possibly as a result of glycogen depletion. We suggest that food deprivation should not exceed one week when Nile tilapia are used as experimental fish.

Effects of skeletal deformities on swimming performance and recovery from exhaustive exercise in triploid Atlantic salmon

The occurrence of spinal deformity in aquaculture can be considerable, and a high rate of deformity has been suggested in triploid smolts in Tasmania. However, the physiological performance of fish with skeletal deformities has not been addressed. The swimming performance and oxygen consumption of triploid Atlantic salmon smolts with either a vertebral fusion (platyspondyly) or multifocal scoliosis were compared to normal (non-deformed) triploid smolts. Fish with vertebral fusion attained swim speeds similar to normal fish, whereas scoliotic fish were unable to attain comparable swim speeds. Routine and maximum oxygen consumption was higher for deformed fish compared with normal fish, translating into apparent increased routine metabolic scope in vertebral fusion fish, and equivocal scope in scoliotic fish compared with normal controls. Deformed fish developed a lower excess post-exercise oxygen consumption compared to non-deformed fish, suggesting they are either incapable of sustained anaerobic activity or possess an increased recovery capacity. These data suggest that skeletal deformity has differential effects on swimming performance depending upon the type of deformity but imposes a significant metabolic cost on salmon smolts.
