The synonymy of Haplochromis pharyngalis and Haplochromis petronius (Cichlidae).

abstract：:Hybrid advantage, described as the superiority of hybrids in some traits over their parents and termed the "heterosis effect," is widely documented in the case of reciprocal crosses of parental species (i.e., hybrids representing the F1 generation). In fish, high survival, fast growth and better health status have bee...
