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

Aquaculture 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 ...

The effects of stocking density and ration on survival and growth of winged pearl oyster (Pteria penguin) larvae fed commercially available micro-algae concentrates

Aquaculture Reports, 2016
Commercially available micro-algae concentrates have been successfully used as an alternative to live micro-algae as a food source during routine larval culture of the winged pearl oyster, Pteria penguin.

Kojic acid inhibited melanin synthesis by tyrosinase pathway in Pteria penguin

Aquaculture Research, 2020
Kojic acid has significant anti‐melanogenic activity in mammals. However, few reports showed its function and mechanism in bivalves. In this study, by survival rate investigation and colour identification, 0.2–5 g/L kojic acid treatment for 24–48 hr was verified to be safe and effective to lighten shell colour of Pteria penguin (Roding; 1798).

Physiological Energetics and Carbon Budget of Three Size Specifications of Pinctada fucata martensii [PDF]

Progress in Fishery Sciences
The continuous rise in greenhouse gas concentrations in the atmosphere, such as carbon dioxide, has triggered a series of climate change issues on a global scale, including global warming, frequent extreme weather events, and sea-level rise.

Screening Relaxants for Efficacy and Effects on Growth for Greenlip Abalone, Haliotis laevigata Donovan

Aquaculture, Fish and Fisheries, Volume 5, Issue 6, December 2025.
ABSTRACT Relaxants are used in abalone aquaculture to facilitate handling, transport and grading stock, with minimal injury, stress, immune suppression and mortality. Benzocaine has been commonly used as an abalone relaxant but negative behavioural responses to exposure have been observed, and in some countries it has a withholding period, precluding ...

Effects of different densities of Isochrysis aff. galbana and Chaetoceros calcitrans on some growth parameters and survival rate of winged pearl oyster spat, Pteria penguin [PDF]

بوم‌شناسی آبزیان, 2016
The growth performance and survival rate of spats of winged pearl oyster (Pteria penguin) fed with two microalgae, Isochrysis aff. galbana and Chaetoceros calcitrans, as well as the combination of both species over a period of 60 days, was evaluated. The

Adaptive Responses in Byssal Growth and Shedding: Insights from Pteria penguin Under Thread Trimming and Non-Trimming Conditions

Journal of Marine Science and Engineering
Bivalves use byssal threads for attachment and locomotion, periodically shedding and regenerating them. In the winged pearl oyster Pteria penguin—known for its strong byssus and its role in the pearl industry—shedding may occur when the byssal stalk ...

Development and characterisation of polymorphic microsatellite markers in the pearl oyster Pteria penguin (Roding, 1798)

Indian Journal of Fisheries, 2016
We developed and characterised 12 polymorphic microsatellite loci for Pteria penguin (Roding, 1798), an important pearl oyster species for pearl production in China. The number of observed alleles per locus ranged from 5 to 26 within 46 individuals.
