“…Plasma calcium and phosphorus have been identified as good indicators of secondary phase of stress response in fish, being used as indirect indicators of altered plasma cortisol levels. Also, stress (Rehulka and Minarík 2007;Dobsikova et al 2009;Roque et al 2010) and pathological situations (Ziskowski et al 2008) may alter the plasma levels of these minerals. On the contrary, plasma magnesium levels were kept constant during starvation, as previously reported for seabream , confirming the low diagnostic value of this parameter for evaluation of the nutritional status.…”

This study was carried out to establish biochemical parameters with potential diagnostic value to assess the nutritional status of healthy seabass. For that purpose, triplicate groups of seabass juveniles were submitted to different feeding protocols: fed for 14 days; fed for 7 days followed by 7 days of fasting or fasted for 14 days. At the end of the trial, body, liver and viscera were randomly sampled for proximate composition analysis. Blood was also collected and the following plasma parameters were analyzed by standard clinical methods: glucose; cholesterol; triglycerides; protein; inorganic phosphorus; calcium; magnesium; alkaline phosphatase (ALP); aspartate aminotransferase; lactate dehydrogenase; creatine phosphokinase and lipase. No major effect of feed deprivation on body composition, visceral index, perivisceral and hepatic lipid content were observed, whereas hepatosomatic index and hepatic glycogen were reduced. Previous feeding conditions strongly influenced the plasma parameters in seabass. Comparatively to the fed group, plasma glucose, cholesterol and calcium levels were reduced after 2 weeks of fasting while plasma triglycerides, protein, inorganic phosphorus and ALP attained minimum levels after 1 week of fasting. Overall, enzymatic activity parameters showed higher variability than biochemistry parameters. In conclusion, during short-term starvation (<14 days) hepatic energy depots were extensively mobilized while perivisceral and body lipids reserves were preserved. Among measured parameters, plasma protein, triglycerides, inorganic phosphorus and ALP seem to have potential as predicative diagnostic tools to assess the nutritional status of seabass and may be useful to monitor feeding practices in aquaculture. Further studies are, however, required to extend results of this study to other fish size classes.

Sobaity sea bream (Sparidentex hasta) is distributed in the Western Indian Ocean, Persian Gulf and Oman Sea. For monitoring health status in this species in an aquaculture condition, standard reference values for haematological and plasma biochemical parameters are indispensable. Heparinized blood samples were collected from 143 healthy sobaity sea bream juveniles raised in cylindrical polyethylene tanks with filtered running seawater. Haematologic reference intervals were as follows: red blood cell (RBC) count 1.67-2.2× 10 6 μL −1 , total white blood cell (WBC) count 8.8-14.5× 10 3 μL −1 , lymphocytes 85-96 %, neutrophils 2-6 %, haemoglobin 28-60 g L −1 , haematocrit (Hct) 24.5-33.8 %, mean cell volume (MCV) 126.3-191.7 fL, mean cell haemoglobin (MCH) 14.4-26.5 pg, mean cell haemoglobin concentration (MCHC) 92-180 g L −1 , erythrocyte sedimentation rate (ESR) 1.5-5 mm h −1 and RBC/WBC ratio 119.2-207.5. Plasma chemistry reference intervals were as follows: total protein 3.2-3.9 g dL −1 , albumin 0.3-0.58 g dL −1 , globulin 2.7-3.4 g dL −1 , alkaline phosphatase 444-866 U L −1 , alanine aminotransferase 239-506.5 U L −1 , lipase 95.5-120 U L −1 , amylase 4-8 U L −1 , sodium 173-211 mmol L −1 , chloride 103-136.5 mmol L −1 , potassium 2.7-4.4 mmol L −1 , calcium 2.6-3.1 mmol L −1 , inorganic phosphorus 2.9-5.3 mmol L −1 , osmolality 430-503 mOsm kg −1 , glucose 6.16-7.88 mmol L −1 , cholesterol 4.07-7.7 mmol L −1 , triglyceride 2.22-3.91 mmol L −1 , high-density lipoprotein (HDL) 1.36-2.44 mmol L −1 , low-density lipoprotein (LDL) 0.84-1.19 mmol L −1 and very-low-density lipoprotein (VLDL) 0.27-0.78 mmol L −1 . Values reported here will be useful for evaluating the health status, interpretation and better understanding of various disease signs in sobaity sea bream juveniles.

“…The shape, size and stiffness of the caudal fin are all expected to strongly affect swimming performance (Plaut, 2000). In nature, the caudal fin is frequently observed to be partly lost due to aggressive behaviour, predation and diseases (Winemiller, 1990;Ziskowski et al, 2008;Sinclair et al, 2011). Thus, fish must physiologically and behaviourally adjust to the probable negative effects on swimming performance caused by caudal fin loss and avoid the decline of Darwinian fitness.…”

The effects of caudal fin loss and regeneration on the swimming performance of three cyprinid fish with different swimming capacities

SUMMARYIn nature, the caudal fins of fish species are frequently lost to some extent by aggressive behaviour, predation and diseases. To test whether the swimming performance of fish with different swimming capacities would be differentially affected due to caudal fin loss and regeneration, we investigated the critical swimming speed (U crit ), swimming metabolic rate (M O2 ), tail beat frequency (f TB ) and tail beat amplitude (A TB ) after caudal fin loss and regeneration (20days) in juveniles of three cyprinid fish species: the qingbo (Spinibarbus sinensis; strong swimmer), the common carp (Cyprinus carpio; intermediate swimmer) and the goldfish (Carassius auratus; poor swimmer). The U crit values of the caudal-fin-lost qingbo, common carp and goldfish were 49, 32 and 35% significantly lower than those of the control groups, respectively. The maximum tail beat amplitude (A TBmax ) (all three fishes), the maximum tail beat frequency (f TBmax ) (only the common carp and the goldfish) and/or the active metabolic rate (M O2active ) (only the common carp) of the caudal-fin-lost fish were significantly higher than those of the control groups. After 20days of recovery, the caudal fins recovered to 41, 47 and 24% of those of the control groups for the qingbo, the common carp and the goldfish, respectively. However, the U crit values of the fin-regenerated qingbo, common carp and goldfish recovered to 86, 91 and 95% of those of the control group, respectively. The caudal-fin-regenerated qingbo and common carp showed a significantly higher A TBmax and f TBmax , respectively, compared with those of the control groups. The qingbo had a higher f TBmax but a lower A TBmax than the common carp and the goldfish, which suggested that a strong swimmer may maintain swimming speed primarily by maintaining a greater f TBmax , for which the caudal fin plays a more important role during swimming, than a poor swimmer. The M O2active of fish (common carp) with a redundant respiratory capacity could increase due to caudal fin loss to meet the increase in energy expenditure required by an increase in f TBmax . In addition, the sustained swimming performance may not be the only selective pressure acting on caudal fin size in these three species, and the present caudal fin size may be a trade-off between sustain swimming performance and other factors (e.g. sexual selection, escape responses).
