“…In an attempt to neutralize this, we acclimatized the fish in large holding tanks for 15 days without disturbance and paid special attention to maintaining a consistent capture protocol throughout the study in order to minimize these stress effects (Nespolo and Rosenmann 2002). Since glucose in serum is a major metabolite of carbohydrate metabolism (Artacho et al 2007), the higher glucose concentration detected in cultured strains should be attributed, in part, to the higher glycogen reserves in artificially cultured fish than in their wild counterparts. Our findings confirm those of Coz-Rakovac et al (2005) who reported a significantly elevated glucose level in farmed Dicentrarchus labrax as compared to the wild ecotypes.…”

Haematological and serum biochemistry parameters were studied and compared between cultured and wild ecotypes of Dojo loach Misgurnus anguillicaudatus during the prime fishing season, i.e. May-August. Data were analysed for the impact of feeding regime and other ecological conditions on the physiology of fish. The results revealed that haemoglobin, cholesterol, total protein, creatinine and uric acid levels in the two ecotypes were significantly different (n = 56, df = 54, P < 0.05). In addition, red blood cell, glucose, triglyceride and urea nitrogen levels were significantly higher in cultured individuals (n = 56, df = 54, P < 0.01) than in their wild counterparts. In contrast, the white blood cell level in cultured fish was significantly (n = 56, df = 54, P < 0.01) lower than that in the wild ones. These differences can be attributed to the physiological acclimatization of the fish to their living conditions and feeding regime, which influences the energy metabolism and, consequently, the health of the fish.

“…The higher values found in Northern shoveler (144.6 mg/dl) and European teal (126 mg/dl) compared to non-migratory birds, e.g. Black-necked swan (Cygnus melanocoryphus), 90 mg/dl (Artacho et al, 2007), may be due to elevation of triglyceride levels in migratory birds since they constitute the important source of energy mobilized from the fat deposits in order to permit them to migrate (Jenni-Eiermann et al, 2002;Jenni-Eiermann & Jenni, 1994).…”

“…Changes in plasma biochemical parameters have been used frequently as indicators of nutritional and health status in birds (Artacho, Soto-Gamboa, Verdugo, & Nespolo, 2007;Rodríguez, Tortosa, & Villafuerte, 2005). Measurement of plasma metabolites offers a rapid and reproducible method to study the metabolism and physiological state of free-living birds (Jenni & Jenni-Eiermann, 1998).…”

“…Measurement of plasma metabolites offers a rapid and reproducible method to study the metabolism and physiological state of free-living birds (Jenni & Jenni-Eiermann, 1998). Multiple blood metabolites (lipids, proteins and glucose) are regulated by dietary intake and metabolism and serve as an indicator of the nutritional status of wild marine birds, which is strongly related to the health status (Artacho et al, 2007;Rodríguez et al, 2005).…”

Background: The study of haematological and biochemical parameters is important to evaluate the physiological status in wild birds. In order to carry out ecophysiological or conservation studies, it is important to know the baseline physiological parameters and how these vary with age, sex and life history events. Results: Haematological parameters including red blood corpuscles (RBCs), white blood cells (WBCs), haematocrit, haemoglobin and related RBC indices and plasma and biochemical parameters including glucose, lipid profile and liver function tests, kidney function tests and electrolyte concentration reference values were determined in two long-distance migratory species from the family Anatidae, the northern shoveler (Anas clypeata) and Eurasian teal (Anas crecca), during migration season. Data revealed significant inter-species differences for most blood and biochemical parameters. These differences are likely due to different feeding habit, diet and species-specific migration behaviour rather than phylogenetic reasons or different environmental condition as they winter at the same place (Máñez et al., Conservation Monitoring in Freshwater Habitats, 2010). Conclusion: To our knowledge, this is the first study that performs a comparative blood analysis on northern shoveler and Eurasian teal during their overwintering period in Manzala Lake, Egypt. Due to the lack of haematological studies on both species during migration, the current results represent a contribution to understanding the physiological adaptations that facilitate the use of different habitats in these species and for establishing reference physiological values and for comparison within the same species, or even with other species in different periods with regard to their use in future conservation efforts or other studies.

“…Previous studies in South America have used only free-living waterfowls (artaChO et al 2007, GaLLO et al 2013) and captive psittacines (aLLGayer et al 2009). Thus, the present study is the first to investigate the relationship between blood glucose/ketone body concentrations with ecological variables and body condition in a free-living South American passerine.…”
