Studies on the Relationships of Mineral Elements in Mud, Water and Blood of Walking Catfish, Claries batrachus(Linnaeus) in the Fishpond in Nakhon Pathom, Lop Buri and Suphan Buri Provinces.

Abstract

The Relationships between the mineral elements in mud, water and in the blood of the walking catfish Clarias batrachus (Linnaeus) were studied. The samples were collected during January to August of 1985 from three provinces, Nakhon Pathom, Lop Buri and Suphan Buri. Nine mineral elements, including sodium (Na), potassium (K), iron (Fe), zinc (Zn) Magnesium (Mg), manganese (Mn), calcium (Ca), phosphorus (P) and copper (Cu) were analyzed. The result showed that the concentrations of mineral elements in the mud and water sample were not different. The amount of the mineral elements in the walking catfish blood was high. The information obtained from walking catfish blood could be used as a guideline for the future research on the mineral elements in the aquatic animals.
