“…After 24 hours of food deprivation in the current trial, glucose levels in test fish were similar to levels reported in prev ious studies (Peres et al, 1999, Sitja-Bobadilla, et al, 2005Peres et al, 2013). This was attributed to the ability of sea bream to quickly restore basal glucose levels after feeding (Peres et al, 2013).…”

The study investigated the effect of increasing dietary inclusion of M annan oligosaccharide (M OS) on growth and blood parameters of sea bream (Sparus aurata). Varying concentrations of M OS were added to commercial sea bream feed at 0‰ (control), 1, 2, 3 and 4‰. At the end of the 15 week trial, control group had the highest final weight, specific growth rate, feed conversion ratio and protein efficiency ratio (P<0.05), although these did not differ among the M OS containing groups (P>0.05). Survival rates were higher in the M OS treatment groups. Blood parameters, did not differ among treatment groups (P>0.05). The lowest alkaline phosphatase (ALP) value was measured in the control group whereas the highest was recorded in the 4‰ M OS group. The lowest level of triglycerides was measured in the 4‰ M OS group, while the highest level of triglycerides was measured in the control group. Cholesterol level was lowest in the 2‰ M OS group (P<0.05). The study showed that the inclusion of dietary MOS has no negative effects on growth and blood parameters in sea breams. However, dietary M OS inclusion led to higher survival rate in trial fish.

“…A high glucose load either through diets rich in digestible starch or by glucose injection results in prolonged hyperglycaemia in carnivorous fish [2][3][4]. The mechanisms that may explain the distinct capacity of species to metabolise glucose are not fully understood.…”

Response of hexokinase enzymes and the insulin system to dietary carbohydrates in the common carp,Cyprinus carpio

et al. 2004

-The response of the common carp to diets with varying amounts of digestible starch, provided either as pea meal (LP, HP, 30 and 46% peas, respectively) or as cereal (LW, HW, 30 and 46% wheat, respectively), was studied and compared with the response to a carbohydrate-free protein-rich diet (CF). Here we focused on the utilisation of dietary carbohydrates by examining the relationship between dietary starch intake, hepatic hexokinase activities, circulating insulin and muscle insulin receptor system. Plasma glucose concentration and hepatic high Km hexokinase (glucokinase, GK) activity were not affected by the content of digestible starch, but 6 h after feeding enzyme activity was higher in the fish fed carbohydrate diets. Similarly, low Km hexokinase (HK) activity was also higher in the fish 24 h after feeding. Fat gain and protein retention were significantly improved by increased digestible starch intake, especially in the HP group, which in turn, presented the highest plasma insulin levels. Glycogen stores were moderately increased by the ingestion of digestible starch. The number of insulin receptors was greater in the CF group than in fish on carbohydrates, except the HP group. Our results confirmed that the common carp uses dietary carbohydrates efficiently, especially when there are provided by peas. This efficiency might be related to the enhanced response of postprandial insulin observed in the HP group.

“…However, the increasing trend of the HSIs observed here was not significantly (p>0.05) important (Table 7). The liver is known to have a function as the deposition site for fat and glycogen in fish [65,66]. Dietary carbohydrates were reported to stimulate glycolysis, glycogenesis and lipogenesis, while reducing protein catabolism and gluconeogenesis [67].…”

Abstract:In the present study, the effects of different dietary protein levels on salema porgy, Sarpa salpa (Linnaeus, 1758) juveniles were investigated. Six iso-caloric (20 kJ/g diet) diets with increasing protein levels (30, 37, 40, 47, 50, and 57%) were formulated. Each test diet was randomly fed to triplicate groups of 13 juvenile fish (initial mean weight 19.28±0.13 g) to satiety over 90 days. Growth performance and feed utilization were best with low dietary protein levels of 30 and 37%, but decreased with diets containing protein levels over 40%. Ammonia nitrogen excretion showed an increasing trend as dietary protein levels gradually increased, whereas retention rates of ammonia nitrogen per intake were highest in the low protein groups of 30 or 37%. The analyses of specific growth rate by broken-line regression indicated that the optimal dietary level of protein for salema porgy juvenile were 33.6% under the conditions applied in this study. As a result, S. salpa demonstrated better growth with low protein diets, showing that this marine fish could be a promising candidate for a sustainable and environment friendly aquaculture industry.
