A previous study predicted the evolution of monogamy in symbiotic crustaceans inhabiting scarce, relatively small hosts in tropical environments where predation risk away from hosts is high. This prediction was tested in the shrimp Pontonia margarita, which inhabits the pearl oyster Pinctada mazatlanica.

Abstract Gonadic conditioning of pearl oyster Pinctada mazatlanica was studied under two water temperature regimes using cultured specimens. Before starting conditioning, specimens were induced to spawn with thermal shock. Two different regimes were evaluated, controlled temperatures (CT) and gradually increasing temperatures (IT).

Summary The present work deals with the existence of differential gonadal development between grafted and ungrafted specimens of the pearl oyster, Pinctada mazatlanica. Oysters were collected as spat and extensively cultured until they were suitable for pearl formation.

ABSTRACT We evaluated indicators of quality for female gonads (ovary and oocytes), male gonads (testis and seminal tubules), and selected somatic tissues (fiber packages in the adductor muscle and adenomeres in the digestive gland) that participate in reproduction of the pearl oyster Pinctada mazatlanica.

Pearl oysters Pinctada mazatlanica (Hanley 1856) and Pteria sterna (Gould 1851) were studied for an annual cycle of in situ growth from May 1992 to April 1993. Organisms generated from extensive culture were kept under repopulation conditions at Caleta El Merito. Growth measurements of shell height and length were taken monthly. Data were used to build

The present work deals with the temporal and bathymetrical variations of the epifaunal community associated with two species of pearl oysters (Pinctada mazatlanica and Pteria sterna) during a seed collecting season from June to November 1989. A total of 63 items (species, genera and/or families) were recorded; their variations in presence and abundance

ABSTRACTThe mother‐of‐pearl oyster Pinctada mazatlanica (Hanley, 1856) obtained full protection from the Mexican government after the fishery collapse in 1939. P. mazatlanica was listed in 1994 as a threatened species in the “Special Protection” category. However, no quantitative assessment of the state of the population has been done so far. Our study
