Abstract
This study was conducted to analyze the differences in characteristics due to paternal influence occur to induce hybridization with female red spotted grouper and giant grouper, tiger grouper sperm. The fertilization rate were 89.0% in red spotted grouper ♀ X red spotted grouper ♂ (RR), 27.0% in red spotted grouper ♀ X tiger grouper ♂ (RT), 30.0% in red spotted grouper ♀ X giant grouper ♂ (RR). And fertilization rate of RR (control) is higher than other species. Hatching rate were 31.3% (RR), 18.8% (RT), 16.0% (RG), respectively. Result in observation the hybrid of three kinds(red spotted grouper, giant grouper, tiger grouper) by the egg occurrence speed and grow size, similar to the male progenitor egg occurrence speed was fastest in the RR of the control incubation phage. Length was the smallest as 2225.0 in the RR(control), however RG(hybrid) was the most fast growing in 2419.5. RT had a medium-growth rate, 2338.5.spotted grouper ♀ X red spotted grouper ♂ (RR), 27.0% in red spotted grouper ♀ X tiger grouper ♂ (RT), 30.0% in red spotted grouper ♀ X giant grouper ♂ (RR).
