“…Energy production through this intermediate takes place either by its entering to the Krebs cycle or by its oxidation. The liver is the main site of amino acid deamination in many fish species studied so far (Fynn-Aikins et al 1993;Enes et al 2006;Kumar 2009). There are, in addition, reports of muscle aminotransferase activity in fishes (Sarma et al 2009).…”

The effect of higher packing density and increased duration of transport on the survival and key metabolic enzymes of Labeo rohita fry was investigated. L. rohita fry (length 40 +/- A 5 mm, weight 0.60 +/- A 0.13 g) were packed in two different densities 40 and 80 g/l and sampled at 0, 12, 24, and 36 h after packing. Results showed that packing density and length of confinement severely affected the survival of the fry. The whole-body glucose level and the activities of the enzymes, lactate dehydrogenase (LDH), malate dehydrogenase (MDH), glucose-6-phosphatase (G6Pase), fructose-1, 6-bisphosphatase (FBPase), aspartate amino transferase (AST), alanine amino transferase (ALT), and adenosine triphosphatase (ATPase) assayed from the fish whole-body significantly (P < 0.05) increased due to increase in the length of the confinement. However, acetylcholine esterase (AchE) activity decreased significantly (P < 0.05) with increase in the length of confinement. Similarly, higher packing density also significantly (P < 0.05) increased the glucose level and activities of all these enzymes (except AchE). The results revealed that both higher packing density and increased transportation duration mobilize protein resources for glucose production via gluconeogenesis and subsequently activate the glycolysis pathway for energy. The rise in the ATPase activity indicates disruption of the osmoregulatory function and the role of this enzyme in ameliorating it. Overall results suggest that normally practiced packing density of 40 g/l is optimum up to 24-h duration for seed transportation

“…AST and ALT are the two most important transaminase found in the liver of fish, which is responsible for the deamination of amino acids (Walton & Cowey, 1982;Alexis & PapaparaskevaPapoutsoglou, 1986;Fynn-Aikins et al, 1993;Enes et al, 2006;Kumar et al, 2009;Kumar et al, 2010). In addition to liver, muscle tissues also have aminotransferase activity in fishes (Alexis & Papaparaskeva-Papoutsoglou, 1986;Kumar et al, 2010).…”

A 60-day feeding trial was conducted to study the nutrient utilization and growth performance of Labeo rohita fed with T1 [DORB supplemented with phytase and xylanase (0.01% each)], T2 [ T1+ L-lysine(1.4%), L-methionine (0.4%), combination of EPA and DHA (0.5%)] , T3 [DORB supplemented with phytase (0.01%), combination of xylanase and cellulase (0.075%), L-lysine (1.4 %), L-methionine (0.4 %), combination of EPA and DHA (0.5%)] and T4 (commercially available carp feed) diets. Weight gain%, SGR, and FCR were similar (p>0.05) for the fishes fed with either T3 feed or commercial carp feed (T4), whereas PER was highest for the T3 group. A significantly higher apparent dry matter and carbohydrate digestibility were observed in the T3 group. Highest crude protein digestibility was observed in T4 group, though lipid digestibility was similar in both T3 and T4 groups. The activities of digestive enzymes were similar in T2, T3 and T4 groups, whereas the lowest activity of these enzymes were observed in T1 group. Based on the findings it is concluded that T3 feed (crude protein 18.18 %) is having comparable growth performance of Labeo rohita as compared to T4 diet (crude protein 32.01 %) due to higher In vivo digestibility.

“…Because DNL is directly dependent on NADPH, the rate of synthesis of this cofactor via the committing oxidative pentose phosphate pathway enzyme, G6PDH, can also, in principle, exert a strong degree of control on DNL activity. A positive correlation between dietary CHO level and G6PDH activity has been reported for seabass (6,12,14,40) as well as the gilthead seabream (Sparus aurata) (22,43,47). Others report that increased levels of CHO failed to stimulate G6PDH activity in seabass (48,49).…”

“…It is worth noting that line selection, a process that has taken centuries for terrestrial farmed animals, is just taking its first steps in fish farming. The influence of dietary CHO on DNL in seabass has been, in most cases, derived from combining analyses of FA profiles in different tissues (6,13,35,36) with determination of the activities and/or expression levels of metabolic pathway enzymes directly involved in DNL as well as NADPH generation (6,12,(36)(37)(38)(39)(40)(41)(42). Recently, these partially successful in explaining the metabolic response to CHO supplementation of fish feeds, particularly for carnivorous fish (26,27).…”

In aquaculture, there is high interest in substituting fishmeal protein with carbohydrate (CHO)-based substrates such as vegetable starch. Procurement of fishmeal protein remains highly dependent on overexploited wild fisheries (1); hence any reduction in its consumption by farmed fish would reduce the ecological burden and improve the sustainability of aquaculture (2). Furthermore, to the extent that dietary CHO replaces protein for systemic glucose and energy demands (3), it decreases waste ammonia generation from protein catabolism, thereby reducing nitrogenous effluents. For carnivorous fish such as the European seabass (Dicentrarchus labrax L.), the efficacy of this approach depends on the capacity of the fish to adapt from their natural diet that is high in both protein and fat, but lacking in CHO, to a regime where the proportion of dietary CHO to total caloric content is increased (4). The capacity to digest complex CHO varies widely between different fish species (5). Generally, carnivorous fish are poorly able to digest raw starch (RS). Cooking or gelatinizing the starch significantly improves its digestibility Abstract Farmed seabass have higher adiposity than their wild counterparts and this is often attributed to carbohydrate (CHO) feeding. Whether this reflects a reduction in fat oxidation, increased de novo lipogenesis (DNL), or both, is not known. To study the effects of high CHO diets on hepatic TG biosynthesis, hepatic TG deuterium ( similar hepatic TG levels to CTRL. DS-fed fish showed higher activity for enzymes that can provide NADPH for lipogenesis, relative to CTRL in the case of glucose-6-phosphate dehydrogenase (G6PDH) and relative to RS for both G6PDH and 6-phosphogluconate dehydrogenase. This approach indicated that elevated hepatic adiposity from DS feeding was not attributable to increased DNL.-Viegas, I., I.
