Effect of temperature on growth and energy budget of juvenile cobia (Rachycentron canadum)

Effect of water temperature on energy budget of Nile tilapia, Oreochromis niloticus

“…High water temperature could result in decreased growth and feed conversion, which have been observed in Nile tilapia (Azaza et al 2008), cobia (Rachycentron canadum) (Sun et al 2006), Atlantic salmon (Salmo salar) (Handeland et al 2008). In the present study, although no significant difference was observed, lower feeding rate was only recorded at 25°C and then feeding rate slightly increased with water temperature and decreased at highest temperature.…”

“…Increased water temperature normally resulted in increased oxygen consumption (Maricondi-Massari et al 1998;Atkins & Benfey 2008) and SDA (Luo & Xie 2008) and therefore increased the energy used for heat increase. In cobia, optimal water temperature could obtain lower faecal production (Sun et al 2006). Increased faecal energy with increasing water temperature was reported in Laternula marilina (Zhuang 2005).…”

“…Decreased growth efficiency in energy with increased water temperature had been reported in juvenile walleye Pollock (T. chalcogramma) (Kooka et al 2007). Sun et al (2006) reported that juvenile cobia showed lower growth energy at lower or higher water temperature. The present study showed that the proportion of food energy channelled into excretory energy (UE + ZE) decreased while HE increased with increased water temperature.…”

“…RE = IE ) FE ) (UE + ZE) ) HE. Water temperature could affect fish growth and feed utilization through the partitioning of food energy into different components of energy budget (Russell et al 1996;Maricondi-Massari et al 1998;Ruyet et al 2004;Sun et al 2006;Atkins & Benfey 2008;Luo & Xie 2008).…”

“…Temperature is the most important abiotic factor which directly influences the fish growth performance, carcass composition and energy requirement of fish (Brett and Groves 1979;Corey et al 1983;Russell et al 1996;Sun et al 1999Sun et al , 2000Sun et al , 2006Person-Le Ruyet et al 2004,Bureau & Hua 2008Helland et al 2010;Amin et al 2014).Since fish is a poikilothermic animal,their growth performances, nutrient utilization, feed conversion and other physio-metabolic functions are influnced with temperature (Houlihan et al 1993;Britz et al1997;Jobling 1997;Azevedo et al 1998).A rise in water temperature increases the metabolic rate of aquatic organisms and therefore their energy requirement. In India, culture of this fish is propagating in many parts of the country having different temperature range that varies from 20°C to more than 35°C.…”
