Haematological and serum biochemical characterization and comparison of wild and cultured northern snakehead (Channa argus Cantor, 1842)

Abstract

The objective of this study was to compare haematological and serum biochemical parameters of cultured and wild specimens of the northern snakehead, Channa argus, to establish baseline values. Thirty sexually immature and disease-free wild fish (37.70 ± 13.68 cm total length, 555.3 ± 449.0 g weight) and 30 cultured fish (36.82 ± 1.72 cm total length, 450.5 ± 58.8 g weight) were examined. In cultured northern snakehead, the average values of alanine aminotransferases (370.1 IU L )1 ), aspartate amino transferases (1145.3 IU L )1 ), albumin (15.84 g L )1 ), direct billuribin (6.15 lmol L )1 ), urea (1.40 mmol L )1 ), glucose (21.54 mmol L )1 ) and cholesterol levels (6.60 mmol L )1 ) were significantly higher (P < 0.05) than in the wild fish. In wild specimens the corresponding values were 9.81 IU L )1 , 394.1 U L )1 , 12.90 g L )1 , 2.57 lmol L )1 , 0.97, 2.36 and 4.38 mmol L )1 , respectively. No significant difference (P > 0.05) was found for total protein, globulin, total bilirubin, chromium, sodium, chloride or triglyceride levels between wild and cultured populations. The mean values of the red blood cell (RBC) counts, hematocrit, haemoglobin, and mean corpuscular volume (MCV) were significantly higher (P < 0.05) in the cultured population, while the values of the white blood cell (WBC) counts, erythrocyte sedimentation rate (ESR), mean corpuscular haemoglobin (MCH), and mean corpuscular haemoglobin concentration (MCHC) were significantly higher (P < 0.05) in the wild population. The study showed that the environmental conditions significantly impacted the status of the fish. It is suggested that these physiological parameters can be conveniently employed as health monitoring tools in fish culture practices.

The effect of diets containing different levels of active charcoal on growth performance, body composition, haematological parameters and possibility of heavy metals detoxification in big sturgeon (Huso huso)

“…Also, triglycerides and cholesterol are the main indicators of fish health. Cholesterol is a precursor to the steroid hormones so that too much increase in cholesterol indicates disorder of lipid metabolism and lipoprotein which particularly damage physiological function of the liver (Gul, Gao, Qian, & Wang, ). In this study, the best haematological parameters especially after challenging with heavy metals were obtained in 15 g/kg treatment.…”

Concentration of fish serum albumin (FSA) in the aqueous extract of Indonesian Perciformes fishes’ muscle tissue

“…The FSA concentration in fishes from the Carangidae, Lethtinidae, Menidae and Scrombridae families was above 10 g/L, a value similar to that found in wild snakehead fish. Gul et al (2011) found that the FSA concentration in wild and cultured snakehead fish was in the range of 12.90-15.84 g/L. This result showed wild fishes from the family Scrombidae to have similar amounts of FSA as the wild snakehead fishes.…”

“…The analysis also revealed that the variation between individual species within the families Caragidae, Lutjanidae and Scombridae was insignificant. The level and properties of FSA are known as parameters that can be used to monitor fish health and prevailing environmental condition in which fishes live (Gul et al 2011). Our samples were purchased from the same fish market, meaning they were likely caught by local fisherman using traditional methods and from a similar geographical location.…”

Effect of Dietary Protein Level on Growth Performance and Blood Parameters of Marbled SpinefootSiganus rivulatus

“…Although in fish ALT and AST are present in various organs, an alteration in their activity is usually, but not definitively, an indicator of liver damage or dietary stress (Gul et al 2011;Wilson 1973). In the present study the levels of ALT activity were not significantly different from each other in serum of fish from the various treatments, although activity appears to increase with increasing dietary protein.…”
