Project for Ph. D Degree

In recent years, much progress has been made in the rearing of fish larvae fed only with artificial diets. The current research was made in an attempt to evaluate the effects of live food and formulated diets (varying in dietary protein level) on survival, growth and body protein content, main digestive enzymes activity and these enzymes gene expression of Plelteobagrus fulvidraco under different developments (from first feeding to young fish).

Future Research

In the near future, the research will focus on mechanisms of carbohydrate utilization in sturgeon. The research process is from genotype to phenotype by using molecular, enzymatic, everted gut sleeve and combined intubation techniques. The research will (1) use several biological techniques to develop energetics, metabolic, absorptive, and enzyme kinetic models; (2) characterize key digestive and metabolic enzymes and glucose transport; (3) gene expression of these key enzymes and transporter; and (4) reconciles among the various models to give us a better understanding on the carbohydrate utilization by sturgeon. The biological techniques use to develop the energetic, metabolic, absorptive model are dose and growth response trials (apparent digestibility coefficient determination), the combine technique of esophageal intubation, dorsal aorta cannulation, and urinary catheterization, and everted gut sleeve and/or brush boarder membrane vesicle techniques, respectively.
