Karakterisasi fenotipe benih hibrida interspesifik abalon
ABSTRACTAbalone is one of sea-water aquaculture commodity that having relatively low in growth and survival. Interspesific hybridization between abalone Haliotis asinina and Haliotis squamata is required to produce hybrid seeds having a better phenotype inherited from their parents. Crossbreeding of abalone was done in the reciprocal procedure with a natural spawning technique on mass scale. The hybrid seeds showed higher similarity with female brood (98,69%), while the larvae from H. squamata × H. asinina were abnormal on trocophore until early veliger phase then dead occurred the next phase. The results showed that hybridization between male H. asinina and female H. squamata had higher fertilization and hatching rate than its reciprocal i.e. 76.01±6.15% and 60.14±4.80%.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
