Haematology and biochemical parameters of different feeding behaviour of teleost fishes from Vellar estuary, India

Abstract

Haematological parameters have been recognized as valuable tools for monitoring fish health. Haematological and serum biochemical parameters were studied and compared different feeding behaviour of teleost fishes. Three marine teleost fishes, Lates calcarifer (carnivores), Mugil cephalus (omnivores) and Chanos chanos (herbivores), were carried out in order to find out a normal range of blood parameters which would serve as baseline data for assessment of the health status of the fish as well as reference point for future comparative surveys. Blood parameters such as red blood cell count (RBC) and white blood cells count (WBC), haemoglobin, haematocrit, mean cell haemoglobin concentration (MCHC), mean cell volume (MCV), mean cell haemoglobin, glucose, protein, cholesterol and urea were estimated from teleost fishes of different trophic level. Statistical analysis revealed that differences in haematological parameters between marine fish were significant (P<0.01). The result revealed that haematological RBC/WBC ratio, MCV and MCHC were significantly correlated at P<0.05 level. The RBC/WBC level increased due to the decrease in WBC during the study. Blood serum biochemical parameters can be used for confirming the maturity and monitoring any changes in the quality of waters and related soils.

Effect of Selenium Incorporated in Feed on the Hematological Profile of Tilapia (Oreochromis niloticus)

“…Satheeshkumar et al [48] reported that correlation of different blood parameters such as RBC/WBC ratio, MCV and MCHC was significant at P<0.05 level, therefore supporting the results coming out of the present study. The level of WBC decreased during the whole study due to increase in RBC level.…”

Dietary zinc requirement of Siberian sturgeon (Acipenser baerii, Brandt 1869) juveniles, based on the growth performance and blood parameters

“…Although the normal ranges for biochemical key parameters have been identified for various raised fish species (Kopp et al 2009;Xiaoyun et al 2009;Satheeshkumar et al 2011;Liang et al 2012), there is scare information about the blood characteristics in Siberian sturgeon especially under culture conditions. Results of the present study illustrated that supplemental dietary Zn improves the hematological parameters of Siberian sturgeon.…”

Вiochemical Parameters of Blood in Fish from Zaporozhian Reservoir

“…The cause of elevated level of protein in the fish blood from Samara Bay can be increased content of toxic substances in the area, including heavy metals that affect the liver, which synthesizes albumin and globulins. Increased concentrations of protein in blood plasma can be caused by structural changes in the liver, which lower the aminotransferase level with the simultaneous reduction of desamidization strength [11].…”

“…In addition, researching of blood parameters will make it possible to understand the biological and ecological characteristics of certain species of fish depending on their age and gender [7][8][9][10][11].…”
