In vitro hybridization of coral trouts, Plectropomus leopardus (Lacepede, 1802) and Plectropomus maculatus (Bloch, 1790): a preliminary investigation.

摘要

This study investigated the utility of hybridization between coral trouts and compared the performance of purebreed and hybrid larvae in captivity. The growth, heart rate and survival of the coral trouts were measured as indicators of larval performance. The study showed that in vitro hybridization of gametes from heterospecific coral trouts yielded free-swimming larvae and that the performance of hybrid and purebreed larvae was similar during early ontogenic stages. Future attempts to hybridize coral trouts should commence once suitable feeding protocols have been developed for these species..
