TÓM TẮT
The paper presents the results from a survey of grouper fingerling/seed availability carried out in 2012-2013 in the coastal coral reef of Son Tra, Da Nang, Vietnam. The purpose of the survey was to evaluate the potential use of wild seed for mariculture. Eight grouper species were found: chocolate hind Cephalopholis boenak (Bloch, 1790), yellow grouper Epinephelus awoara (Temminck & Schlegel, 1842), orange-spotted grouper Epinephelus coioides (Hamilton, 1822), Malabar grouper Epinephelus malabaricus (Bloch & Schneider, 1801), rock grouper Epinephelus fasciatomaculosus (Peters, 1865), blacktip grouper Epinephelus fasciatus (Forsskål, 1775), threespot grouper Epinephelus trimaculatus (Valenciennes, 1828), and Epinephelus sp. Among them, yellow, Malabar and orange-spotted groupers are of high economic value and are cultured in Vietnam. Grouper seed were of different sizes depending on the species, ranging from 58 to 152 mm, with an average density of five individuals per 400 m2. They were found at all sampling stations, with highest density at Vung Da (10 individuals/400m2), followed by Bai Nom and Hon Sup; and occurred mainly from May to September each year.
