Pearl oyster farming in the coastal water of Bandar-Lengeh (north Persian Gulf)

Abstract

A Number of adult pearl oyster Pinctada radiata were investigated. They were divided in to three groups for nucleous implantation: spherical, half and blanc (no implantation) in Bandar-Lengeh. Oyster’s panels were hung on line in 3 meter depth. Over the following 5 months, heavy mortality occurred and over 90% of implanted oysters died. The analyses of variance (ANOVA) showed no significance difference in the rate of mortality. Major aspects of mass mortality could be: the high silt load of the farm, infestation of fouling and boring organisms and the surgical operation.
