“…LDH, CS and HOAD activities were significantly higher in PM, which indicates a higher capacity for ATP generation in the caudal region of the body. Similar results have been reported for cod ( Gadus morhua ) [15] which like shi drum also presents a subcarangiform locomotive pattern. Regarding antioxidant enzymes ( Table 2 ), higher SOD and G6PDH activities, and a non significant tendency for increased GPX and CAT activities were observed in PM, which may be related with the higher aerobic capacity of this body region.…”

“…It is well established a regional heterometry of muscle metabolic capacities in fish that, at least in part, is based in regional differences in the contribution of muscle during swimming [33] , [15] , [17] , [11] . It has been reported that metabolic consequences of starvation vary depending on the body region considered [11] , [17] .…”

Regional asymmetry of metabolic and antioxidant profile in the sciaenid fish shi drum (Umbrina cirrosa) white muscle. Response to starvation and refeeding

The objective of the present study is to characterize the metabolic and antioxidant profile of white muscle of shi drum in two sites of the body, anterior dorsal (AM) and posterior dorsal (PM) portions. In addition, it will be analyzed the possible effect of starvation and a subsequent refeeding, with two different protocols, pair feeding and ad libitum. Activities of key enzymes of intermediary metabolism and of antioxidant enzymes, as well as lipid peroxidation, as an index of oxidative stress, were evaluated. The results indicate the existence of a regional asymmetry of the metabolic capacities of the white muscle of shi drum, which is likely related to the different contribution to swimming of the body regions examined. Starvation induces a metabolic depression that is more marked in those activities that support burst swimming in PM, while those activities supporting maintenance requirements are conserved. The greatest energy demands during starvation appear to lie in AM, which showed the highest oxidative metabolism rate. The increased use of fatty acids as energy source for AM leads to oxidative stress. A period of more than four weeks of refeeding for full restoration of metabolic capacities in AM is needed, probably related to the higher muscle mass located in this region. On the contrary, all enzyme activities in PM returned to control levels in both refeeding protocols, but pair feeding seems to be advantageous since compensatory growth has been taking place without signs of oxidative stress. This work was addressed to gain knowledge on the physiology of a promising fish species in aquaculture like shi drum. The results displayed here show how the starving and further re-feeding events could generate oxidative stress situations characterized by high lipid peroxidation levels which may influence negatively on the quality of the edible part of the fish. This study opens an interesting field on this fish species which deserves being investigated in the future.

“…Highest values in LDH activity and lipid peroxidation level for wolffish hybrids seem not to be a response to hybridization but rather a response to fish mass. LDH profile linked to weigh is in accordance with previous studies on wolffishes and other species [36][37][38][39][40][41]. TBARS essay is an integrative parameter that quantified malonedialdehyde accumulation in tissues and our results suggest an allometric scaling of oxidative stress in the early life stages in fish.…”

Physiological indicators such as lipid peroxidation and enzymes involved in aerobic/anaerobic energy metabolism were measured in pure and hybrid lines of wolffish juveniles (Anarhichas minor, ♀ A. minor ⨯ ♀ A. lupus). Interspecific hybridization was introduced as a powerful tool to promote augmentation of phenotypic variability and consequently improve our capacity for the detection of clear physiological relationships amongst oxidative stress and metabolic characters. Mitochondrial sequence genes analysis between the Atlantic (A. lupus) and spotted wolffish (A. minor) were later performed to further assess the extent of divergence between A. lupus and A. minor mitochondrial haplotypes. The observed divergences (2.0% and the number of nonsynonymous substitution n=23) do not seem to be sufficient to generate detectable differences in ETS complexes catalytic capacities. Total LDH activity was however higher in hybrids than in the pure strands and tightly correlated to TBARS levels which suggest that LDH actively participates to the regulation of cellular redox status. Our results are discussed in comparison with a similar study on a charr hybrid (Salvelinus alpinus × S. fontinalis).

“…Tissues were dissected from freshly euthanized laboratory fish (see above) and stored at −80° C until used. Skeletal muscle samples were from the epaxial muscle mass for all fish (dorsal to the lateral line and between the head and dorsal fin) to avoid variation in muscle metabolic capacities that occur along the body (Martínez et al ., 2000). …”

This study evaluated whether the African cyprinid Barbus neumayeri from Rwembaita Swamp (low-oxygen) and Njuguta River (high-oxygen) in the Kibale National Park, Uganda differed in traits related to aerobic and anaerobic metabolic potential. Haematocrit was measured as an index of blood oxygen-carrying capacity, and tissue activities and isozyme composition of lactate dehydrogenase (LDH) were measured as indices of tissue anaerobic capacity. To address whether site-dependent differences were acute responses v. longer-term adjustments to environmental conditions, these variables were measured in fish sampled shortly after collection and after laboratory maintenance under well-aerated conditions. In fish sampled in the field, those from the low-oxygen site had significantly higher haematocrit, but this difference disappeared after long-term laboratory maintenance. In contrast, fish from the low-oxygen site had higher liver LDH activities than fish from the high-oxygen site, and this difference persisted during laboratory maintenance. Polymorphism was detected at both the LDH-A and LDH-B loci, and genotype frequencies for LDH-B differed significantly between collection sites. These results demonstrate physiological, biochemical and genetic differences in B. neumayeri from habitats differing in dissolved oxygen availability and suggest both acute and long-term responses to local environmental conditions. # 2004 The Fisheries Society of the British Isles
