Phenotype characterization of interspecific hybrid abalone Haliotis asinina and Haliotis squamata seed

Abstract

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%.

“…Identification of species has traditionally been based on morphological characteristics, such as shell colour pattern and size, in addition to other body characteristics such as the number of open holes, shell sculpture and the colour of the body and tentacles (Dharma 1988;Soelistyowati et al 2013). However, the similarity in many of these characters and their states between species has contributed to taxonomic confusion.…”
