| 摘 要： | Kissing gouramy ( Helostoma temminckii) was introduced into Tasek Merimbun in the 1980 s. We studied their genetic profile using allozyme electrophoresis and found that all loci were monomorphic. The loss of het-erozygotes may suggest that the gouramy are inbreds. They must have reproduced by repeated sib-mating over the years. The severe drought in Tasek Merimbun may have aggravated the genetic erosion further. The genetic variability of kissing gouramy in terms of % polymorphic loci, mean number of alleles per loci and observed heterozygosity level were lower than Cyprinids in the same lake and kissing gouramy from the wild. We also note that kissing gouramy is a fast grower and may threaten the livelihood of indigenous fishes in the lake.
