Nutritional Value of Binary Microalgal Diets for Larvae of the Blacklip Pearl Oyster Pinctada margaritifera (L.)

open access: yesAsian Fisheries Science, 2007
This paper reports on two experiments to assess the nutritional value of cultured microalgae for larvae of the blacklip pearl oyster, Pinctada margaritifera. In the first experiment, two binary diets were assessed and Isochrysis sp.

Optimizing community-based pearl oyster (Pinctada margaritifera) spat collection strategies in the Fiji Islands

open access: yesAquaculture Reports, 2022
Fiji’s cultured pearl sector relies on wild collected oysters (Pinctada margaritifera) for culture stock. Most oysters are collected by community-based spat collection enterprises but there is little information on the optimal duration of spat collector ...

Different food particle sources in the pearl oyster Pinctada margaritifera and its epibionts

open access: yesAquaculture Reports, 2021
Suspended bivalve culture (e.g. longlines) transfers benthic biomass - including bivalves and various epibionts - toward the water column, creating strong trophic interactions with the planktonic compartment.

Colour or no colour in the juvenile shell of the black lip pearl oyster, Pinctada margaritifera? [PDF]

open access: yesAquatic Living Resources, 2012
Pinctada margaritifera mollusc is cultivated in French Polynesia for the production of black pearls. For this study, the colour of juvenile samples (48 days old) was investigated in the visible range spectra (430–700 nm) using spectrophotometry. A first measurement was done with the soft parts still inside the shell (entire animal).

Identification of calconectin, a calcium‐binding protein specifically expressed by the mantle of Pinctada margaritifera [PDF]

open access: yesFEBS Letters, 2006
Nacre or mother‐of‐pearl in the shell of Pinctada margaritifera is composed of 95–99% calcium carbonate and 1–5% organic matrix. In this study, we developed an original technique to characterize the genes differentially expressed in nacre‐forming cells (NFC) by combining suppression subtractive hybridization (SSH), to establish a cDNA subtractive ...

Impact of spat shell colour selection in hatchery-produced Pinctada margaritifera on cultured pearl colour

open access: yesAquaculture Reports, 2018
Beaded cultured pearl farming is a lengthy aquaculture process, particularly when the pearl oysters are produced through a hatchery propagation system, and includes the key steps of artificial breeding, larval and spat rearing before graft operations can

Developing a national spat collection program for pearl oysters in the Fiji Islands supporting pearl industry development and livelihoods

open access: yesAquaculture Reports, 2018
Cultured pearl farming in Fiji relies on wild spat collection to supply the oysters used for pearl production. This supply can be inconsistent and a research program was implemented to determine recruitment of pearl oysters to spat collectors at sites ...
