“…Quantitative measurement has increasingly been used to assess reproductive status in many bivalve species, for example Mytihts edulis (Bayne et al 1978;Newell et al 1982';Hawkins et al 1985), Ostrea edulis (Wilson & Simons 1985), and Pecten maximus (Pazos et al 1996).…”

The annual reproductive cycle of Perna canaliculus (Gmelin) was investigated for 1 year by collecting monthly gonad samples from an intertidal population. Gonads of 50 animals were dissected and photographically recorded on video before being fixed for histological sectioning. The histological gonad sections were examined both qualitatively, using a classification and scoring system (S) and quantitatively, using image analysis technology. The quantitative measures used were the proportion of: (1) sections comprising follicles (FC

“…Moreover, this species was partly destroyed by a parasitic protozoan Bonamia ostrea along the European coasts in the 1980s, resulting in a further strong reduction in its populations and genetic diversity (Renault et al 1995). With an age at maturity of 3 yr and a protandrous alternating hermaphrodite type of reproduction, this species also has a limited larvae distribution that contributes to reducing genetic fluxes between populations (Wilson & Simons 1985).…”

Metallothioneins (MTs) are small essential proteins involved in cellular processes of metal handling and detoxification. Here, we describe the structure of 2 MT genes in a marine mollusc, the European flat oyster Ostrea edulis. The sequences of these 2 genes code for 2 proteins of 74 and 71 amino acids, respectively, with the 71 amino acid protein having an abnormal lack of cysteine residues. The direct quantification of metal ions bound to purified recombinant proteins demonstrated that the metal-binding capacity of the 2 proteins differs by about 20%. An enzyme-linked immunosorbent assay (ELISA) test, used to quantify MT protein expression in O. edulis exposed to metal under laboratory conditions, showed no significant induction of MTs, either in the gills or the digestive gland despite an increase in metal concentration observed in the same tissues. Similar results were observed with an MT-RNA expression study. These results seem to indicate a low involvement of MTs in metal detoxification in O. edulis. Examination of polymorphism in the coding sequence of OeMT (O. edulis metallothionein) genes by single-strand conformation polymorphism (SSCP) revealed a lack of genetic diversity in field populations.

, R. Identificación histológica de las fases gonádicas del ostión europeo (0s~~ edufis) introducido experimentalmente en la porci6n noroccidental de la costa de Baja California, Mkxico. Histological identification of the gonadal phases of the european oyster (Ostrra edulis), introduced experimentally into the northwestem coast of Baja California, Mexico. Ciencias Marinas, lS(2): 41-54, 1989. RESUMENPara conocer la duración de las fases gonádicas del ostión europeo(Ostrea edulis) en Bahía San Quintín, Baja California, se efectuó el seguimiento mensual de los cambios histológicos gonadales de una población de organismos cultivados para este fin, de febrero de 1984 a enero de 1985. Se determinó que la especie desarrolló todas sus fases gonádicas durante el período muestreado, y no se presentó la interrupción del ciclo durante invierno (enero-marzo) debido al peri odo de hibernación que ha sido observado en otras regiones del mundo. ABSTR4CTIn order to study the length of the gonadal phases of the European oyster (Ostrea edulis) in Bahía San Quintfn, Baja California, a population of organisms was cultured and the histological gonadal changes were monitored monthly, from Februaty 1984 to January 1985. The species was found to develop all its gonadal phases during the period sampled and the interruption of the cycle during winter (January-March) due to the hibemation period that has been obsetved in other regions of the world did not occur.
