Critical techniques for selection and sexual determination of broodfish, spawning, egg collecting,and incubation of \%Pelteobagrus fulvidraco\% (Richardson) were studied from 1998 to 1999. 534 females and 533 males were induced to spawn by hormone injection, 104 63×10\+4 eggs and 21 95×10\+4 fry (10-29 mm) being obtained at fertilization rate of 64 4%(85%-30%) and at hatching rate of 57 23% (80%-25%). Fry stocked accounted for 21% (60%-4 4%) of the fertilized eggs. The adaptive temperature for spawn and incubation is 22-28℃,the optimum being 23-26℃
