HISTOLOGICAL STUDY ON HYBRID ABALONE Haliotis squamata x H. asinina

Mass production of abalone Haliotis asinina and Haliotis squamata has been developed. The main problem of abalone farming is slow growth and low survival rate. Hybridization among two species of abalone has been suggested as an alternative action to increase the growth. Hybridization between H. squamata and H. asinina has been developed in BPBL Lombok hatchery. The results of abalone hybrid histology needed to determine the level of normality of hybrid abalone. Most abalone hybrid has the morphology which is a combination of both types of abalone parent, whereas the appearance of hybrid gonad showed normal development.
