“…The energy budget of this study is comparable with those reported for other teleost fish (Fang et al, 2010;Xie et al, 2011). The most similar data set is the energy budget of the Antarctic eelpout, P. brachycephalum, reported by Brodte et al (2006).…”

“…The most similar data set is the energy budget of the Antarctic eelpout, P. brachycephalum, reported by Brodte et al (2006). While routine metabolic costs usually make up about 50% of total energy expenditure in most fish (Brodte et al, 2006;Fang et al, 2010;Xie et al, 2011), the relatively small proportion of energy allocated to routine metabolism (20.8±1.4% at 0°C) in T. bernacchii is noteworthy. Importantly, the measured RMRs in T. bernacchii agree well with recent literature data (Enzor et al, 2013), making an underestimation of metabolic rate seem unlikely.…”

As a response to ocean warming, shifts in fish species distribution and changes in production have been reported that have been partly attributed to temperature effects on the physiology of animals. The Southern Ocean hosts some of the most rapidly warming regions on earth and Antarctic organisms are reported to be especially temperature sensitive. While cellular and molecular organismic levels appear, at least partially, to compensate for elevated temperatures, the consequences of acclimation to elevated temperature for the whole organism are often less clear. Growth and reproduction are the driving factors for population structure and abundance. The aim of this study was to assess the effect of long-term acclimation to elevated temperature on energy budget parameters in the highAntarctic fish Trematomus bernacchii. Our results show a complete temperature compensation for routine metabolic costs after 9 weeks of acclimation to 4°C. However, an up to 84% reduction in mass growth was measured at 2 and 4°C compared with the control group at 0°C, which is best explained by reduced food assimilation rates at warmer temperatures. With regard to a predicted temperature increase of up to 1.4°C in the Ross Sea by 2200, such a significant reduction in growth is likely to affect population structures in nature, for example by delaying sexual maturity and reducing production, with severe impacts on Antarctic fish communities and ecosystems.

Influencia de la temperatura, densidad, oxígeno y alimento en la formación de marcas en las escamas de tilapia Abstract: The influence of temperature, density, oxygen and food in the mark formation on the scales of tilapia. Oreochromis niloticus has been introduced worldwide into freshwater reservoirs and represents an alternative food for local populations. Two annual marks on fish scales have been reported for fish in these environments, one of them is allocated to reproduction, while the other is thought to be formed following low temperatures, a reduction in oxygen concentration and/or high densities, among others. In order to explore the causes of this second ring, we designed an experimental study to analyze the influence of four factors: a reduction in food amount, an increase in density, a decrease in oxygen concentration and temperature. The experiment was carried out using five 215 L plastic tanks, each one divided into two sections, so as to have treatment replicates (each with 20 juveniles). The control conditions were optimal for the species: 5 % of body weight in food, a density of 3 fish/L, a total oxygen saturation of 4.98 ± 0.5 mg/L, and a temperature of 25.0 ± 1.0 o C; the treatments varied as follows: food of 2.5 % of body weight, density of 6 fish/L, oxygen of 2.8 ± 1.2 mg/L and a temperature of 19.6 ± 1.0 o C. Fish responses to stressors were estimated through variations in length, weight and inter-circuli spaces or circuli spacing in fish scales. Every third day it was measured the concentrations of ammonium, phosphates and nitrates with a photometer. Three stages for length/weight fish measurements and scales sampling were considered: 1) Initial stage: before experiment started, 2) Final stage: at the end of the experiment, and 3) Compensatory stage: when all the experimental treatments were adjusted to the Control conditions; the experiments lasted for three weeks. The results indicated that all the treatments caused a reduction in length, weight and inter-circuli spaces when compared to the controls (6.7 ± 0.5 cm; 5.2 ± 1.2 g; 5.4 ± 0.5 mm, respectively), but only the variables of temperature and food resulted significant (5.6 ± 0.4 and 5.8 ± 0.5 cm; 3.4 ± 0.7 and 3.3 ± 0.9 g; 3.4 ± 0.3 and 4.1 ± 0.6 mm for temperature and food treatments, respectively) (P < 0.05). When treatments were reversed to the control conditions for another three weeks compensatory growth was observed in the oxygen and density treatments, but not in the same way for the temperature and food treatments. We concluded that inter-circuli distances are a good indicator to stress periods in this species. Rev. Biol. Trop. 65 (2): 613-622. Epub 2017 June 01.

“…The terminology and symbols for the energy budget followed those proposed by the NRC (1981) and Xie et al (2011): The gross energy intake (IE) and fecal energy (FE) were determined directly. The excretory (non-fecal) energy loss is the product of branchial energy (ZE) plus urine energy (UE) and was calculated from the formula: ZE+UE=24.83(NI-NF-Nr) (where NI is gross nitrogen intake, NF is fecal nitrogen, and Nr is recovered nitrogen).…”

We evaluated the effect of ration level (RL) on the growth and energy budget of lenok Brachymystax lenok . Juvenile lenok (initial mean body weight 3.06±0.13 g) were fed for 21 d at fi ve different ration levels: starvation, 2%, 3%, 4% bwd (body weight per day, based on initial mean values), and apparent satiation. Feed consumption, apparent digestibility, and growth were directly measured. Specifi c growth rates in terms of wet weight, dry weight, protein, and energy increased logarithmically with an increase in ration levels. The relationship between specifi c growth rate in terms of wet weight (SGR w , %/d) and RL (%) was characterized by a decelerating curve: SGR w =-1.417+3.166ln(RL+1). The apparent digestibility coeffi cients of energy exhibited a decreasing pattern with increasing ration level, and there was a signifi cant difference among different RLs. Body composition was signifi cantly affected by ration size. The relationship between feed effi ciency rate in terms of energy (FERe) and RL was: FERe=-14.167+23.793RL-3.367(RL) 2 , and the maximum FERe was observed at a 3.53% ration. The maintenance requirement for energy of juvenile lenok was 105.39 kJ BW (kg) -0.80 /d , the utilization effi ciency of DE for growth was 0.496. The energy budget equation at satiation was: 100IE=29.03FE+5.78(ZE+UE)+39.56 HE+25.63 RE, where IE is feed energy, FE is fecal energy, ZE+UE is excretory energy, HE is heat production, and RE is recovered energy. Our results suggest that the most suitable feeding rate for juvenile lenok aquaculture for wet weight growth is 2.89% bwd, whereas for energy growth, the suggested rate is 3.53% bwd at this growth stage.
