SOME RESULTS OF ABALONE (Haliotis asinina Linaeus, 1758) BREED PRODUCTION IN KHANH HOA PROVINCE
The results of abalone (Haliotis asinina) breed production in Khanh Hoa Province are as follows: After the 30 day - trial farming parent abalone (Haliotis asinina) in cement tanks and the natural habitat, the matured ratio are 57,15% and 63,24% respectively. Spawning with thermal shock combined with UV gives the fertility participation rate of 71,42%. The trial rearing of abalone (Haliotis asinina) of 0.1 cm ÷ 0.5 cm length with different foods shows that the most suitable food is Navicula sp. mixed with chopped fresh algae seaweed and the growth is from 1,0 mm to 3,9 mm, the survival rate is 65,37%. Average survival rate after 5 rounds of artificial breeding is 51,44%.
