Differentiation of steroid-producing cells during ovarian differentiation in the protogynous Malabar grouper, Epinephelus malabaricus.
To understand the mechanism of sex differentiation in the protogynous Malabar grouper Epinephelus malabaricus, we performed an immunohistochemical investigation of the expression of three steroidogenic enzymes, cholesterol-side-chain-cleavage enzyme (CYP11a), aromatase (CYP19a1a), and cytochrome P45011beta-hydroxylase (CYP11b), in the gonads during ovarian differentiation. Strong positive immun...

متن کاملProsorhynchus maternus sp. n. (Digenea: Bucephalidae) from the Malabar grouper Epinephelus malabaricus (Perciformes: Serranidae) off New Caledonia.
A new species, Prosorhynchus maternus sp. n., is described from the serranid fish Epinephelus malabaricus (Bloch et Schneider) in the waters off New Caledonia. It belongs to a group of Prosorhynchus species from serranids in which the uterus is restricted to the postovarian region. Its distinguishing features include the vitellarium relatively distant from the rhynchus, the cirrus-sac relativel...
متن کاملMass Mortality of Cultured Sevenband Grouper, Epinephelus septemfasciatus, Associated with Viral Nervous Necrosis
Mass mortalities of sevenband grouper Epinephelus septemfasciatus reared in Oita Prefecture were investigated. The outbreaks of the disease occurred in summer seasons (July to October; water temperature 25-28°C) of 1993 and 1994. Affected fish ranging 170 to l,85Og in body weight were characterized by upside down swimming and inflation of swimbladder. Histopathologically, necrosis and vacuolati...
