“…Reliance SF generally had the highest BFCR and EFCR values, which was likely correlated with the comparatively high ash content of this diet (12.7% compared with 6.8-7.3% of the other diets). The finding that FCR was also strongly modified by temperature has been observed in other fish species (e.g., Jonassen et al 2000;Bendiksen et al 2002;Van Ham et al 2003;Duston et al 2004;Bailey & Alanärä 2006). There was a 10-37% decrease in BFCR and EFCR for all feed types associated with the increase in water temperature from 14-17°C to 17-22°C, with Reliance SF showing the greatest decrease.…”

A study was undertaken to provide data on growth, feed conversion ratio (FCR) and faecal discharge of yellowtail kingfish (Seriola lalandi) fed three commercial diets used previously to culture this species in New Zealand. Fish were raised in tanks from 0.4 to 1.2 kg over the spring (water temperature 14-17°C) and summer (17-22°C) periods. There were considerable differences in volumetric and mass-specific feed intake, and energy intake amongst diets. Daily crude protein intake was similar amongst diets, although it increased from the cold (4.05-4.50 g protein kg -1 day -1 ) to warm period (6.48-7.67 g protein kg -1 day -1 ). The biological and economical FCR varied with diet (BFCR 1.22-2.17, EFCR 1.30-2.62), as did the cost of feed per unit biomass produced (NZ$2.38-3.78 kg -1 ). Growth rates were broadly similar amongst diets, and the warmer summer temperature period greatly improved both growth (increase from 0.51-0.64% to 1.18-1.23% mass gain day total nitrogen (T N) and total phosphorus (T P) output compared with Skretting NME, which was in turn only half or less of that of Reliance SF

“…Eggs collected from the wild were hatched and reared at the Nova Scotia Agricultural College (Cook, 2003). Juvenile stages were reared in hard fresh water (Duston et al , 2004). The prescribed acclimation temperatures were 5, 10, 15, 20, 26 and 30° C, which were obtained by changing the rearing temperatures by 1° C day −1 .…”

“…Striped bass are a good candidate to assess population differences in thermal tolerance due to their extensive latitudinal range. In addition, body size was included as an experimental variable since there is scant information on its effect on thermal tolerance, however, the optimum temperature for growth of this population appears to decrease with body size (Cook, 2003; Duston et al , 2004) and correlations have been drawn between optimal temperature and thermal tolerance (Jobling, 1981).…”

Thermal tolerance of age 0þ year Shubenacadie River (Nova Scotia, Canada) striped bass Morone saxatilis juveniles (mean AE S.E. fork length, L F , 19Á2 AE 0Á2 cm) acclimated in fresh water to six temperatures from 5 to 30°C was measured by both the incipient lethal technique (72 h assay), and the critical thermal method (C m ). The lower incipient lethal temperature ranged from 2Á4 to 11Á3°C, and the upper incipient lethal temperature (I U ) from 24Á4 to 33Á9°C. The area of thermal tolerance was 618°C 2 . In a separate experiment, the I U of large age 2þ year fish (34Á4 AE 0Á5 cm L F ) was 1Á2 and 0Á6°C lower (P < 0Á01) than smaller age 1þ year fish (21Á8 AE 0Á5 cm L F ) at acclimation temperatures of 16 and 23°C. Using the C m , loss of equilibrium occurred at 27Á4-37Á7°C, loss of righting response at 28Á1-38Á4°C and onset of spasms at 28Á5-38Á8°C, depending on acclimation temperature. The linear regression slopes for these three responses were statistically similar (0Á41; P > 0Á05), but the intercepts differed (25Á3, 26Á0 and 26Á5°C; P < 0Á01). The thermal tolerance of this northern population appears to be broader than southern populations.

“…Glutamic-pyruvic transaminase (GPT), alanine transaminase (ALT), glutamic-oxaloacetic transaminase (Duston et al, 2004), alkaline phosphatase (ALP), lactate dehydrogenase (LDH) and glucose oxidase (Glu-GOD) have all been used as parameters of disease and health status (Wacker et al, 1956;Abdel-Tawwab et al, 2010;Noor El-Deen et al, 2010). Total protein (albumin and globulin) (TP) and total cholesterol (TC) levels are also good indicators of fish health (Yang and Chen, 2003;Yoneyama et al, 2009).…”

The effects of feeding-intensity stress on biochemical indices of the GIFT strain of Nile tilapia were investigated in a recirculating freshwater system. Differences in serum and liver biochemistry, routine blood measurements, and growth were examined in fish fed three experimental rations (2%, 4% and 6% of fish biomass daily). Larger rations led to higher SGR but lower FCR, PER and SR. Smaller rations caused higher levels of HSI and cortisol. Fish on the 2% and 6% diets had lower liver levels of C3, LZM, SOD, Glu-GOD, HDL-C, TG, ALP, CAT and higher T4, AST, MDA than those on 4% diets. The 6% group had the lowest levels of LDH, TP, GSH, and GSH-PX. The 2% and 6% groups had lower blood levels of HGB, MCHC, RBC, and WBC than the 4% group; 2% fish had the highest RDW-CV and RDW-SD levels. Therefore, the optimal feeding rate for GIFT tilapia at about 29°C is 4% biomass/day; 6%/day could increase productivity but would be uneconomical; 2%/day would be unsuitable in the absence of natural food. We conclude that high and low feeding intensities would adversely influence the physiological health of tilapia and their resistance to disease, and reduce FCR.
