LONG-TERM VARIABILITY IN SPAT COLLECTIONS OF THE BLACKLIP PEARL OYSTER (PINCTADA MARGARITIFERA) IN SOLOMON ISLANDS

Journal of Shellfish Research, 2006
Abstract Temporal variation in abundance of spat of the blacklip pearl oyster (Pinctada margaritifera) was determined over an eight-year period at two sites, Gizo and Noro, in the Western Province of Solomon Islands. Spat were collected by deploying shade mesh substrata at a depth of 3 m for near-sequential two-month period.

Spat Collection of a Non-Native Bivalve Species (European Oyster, Ostrea edulis) off the Eastern Canadian Coast

Journal of Shellfish Research, 2008
Abstract A European oyster population (Ostrea edulis) was recently discovered off the Eastern coast of Canada. The occurrence of this population led various aquaculture stakeholders to consider this species commercially. The aim of this study is to determine the best time to collect the European oyster larvae to maximize their collection.

Assessment of artificial substrates for collection of hatchery-reared silver-lip pearl oyster (Pinctada maxima, Jameson) spat

Aquaculture, 1998
This paper reports on three experiments in which artificial substrates were assessed for the collection of hatchery-reared silver-lip (or gold-lip) pearl oyster, Pinctada maxima (Jameson), spat. In the first experiment, pediveliger larvae were settled onto collectors made from a variety of materials: curved PVC slats; polypropylene rope; a combination ...

Characterization of Spatial and Temporal Variability of Crassostrea spp. Spat Settlement to Ascertain Allocable Sites for Spat Collection at Cox’s Bazar, Bangladesh

North American Journal of Aquaculture, 2021
Abstract Spat settlement (spat density, recruitment, and mortality) of edible oysters Crassostrea spp. was estimated for three sites (Nunia Chara [NC], Chowfoldandy [CD], and Sonadia Island [SI]) located along the Cox’s Bazar coast of Bangladesh from February 2019 to January 2020 by deploying shellstrings.

Worldwide overview of reproduction, juvenile collection, spat production and cultivation of pen shells

Reviews in Aquaculture, 2022
AbstractPen shells hold some potential for cultivation, but information on aquaculture activities is fragmentary, and no sustained or commercial production of any such species is currently in place. We reviewed information available worldwide on reproductive cycles, wild juvenile collection, spat production in hatcheries and cultivation systems for 45 ...

Pectinid fisheries, spat collection, and the potential for stock enhancement in the Isle of Man

1991
Pectinids form the most valuable fishery on the Isle of Man. The state of the scallop and queen fishery is reviewed. On heavily fished inshore grounds, scallop population structures have been markedly shifted over the 52 years of exploitation and 70% of the catch is now undersize (<110-mm shell length).

Methods of Collecting Oyster Spat

Transactions of the American Fisheries Society, 1940
Abstract An important phase of the program for the rehabilitation of the once prosperous oyster industry of California has been the development of more efficient collectors for taking natural larvae to be reared on artificial beds. Two exceptionally efficient types of collectors were developed. Their increased efficiency was due to the fact that larvae

Using hanging plastic trays for three-dimensional collection of antique mactra (Mactra antiquata) spat

Aquaculture, 2006
This paper describes the first case of using hanging plastic tray for three-dimensional collection of the spat in the hatchery production of antique mactra. Different numbers of clusters (72, 90, 108) of plastic trays loaded with fine sand were hung in three tanks for three-dimensional collection of antique mactra, while the other two tanks without ...

Natural spat collecting in the pacific oystercrassostrea gigas(thunberg)

Marine Behaviour and Physiology, 1990
The oyster cultivation industry of Hiroshima has a history of nearly 400 years and provides about 70% of the oyster production for the whole of Japan. The favourable location enables all the spat to be produced locally and the number of collector plates used for this purpose each year reaches 200–300 million. The natural system of spat collecting which

Heterogeneity of Japanese Oyster (Crassostrea Gigas) Spat Collection in a Shellfish Farmed Mediterranean Lagoon

2019
Japanese oysters spatfields were recently discovered in the French Mediterranean Thau lagoon farmed for shellfish. This discovery led to interesting issues concerning research for a highly seashell exploited ecosystem. The analyses of various environmental parameters characterized favorable sites and periods for spat collection. Spat collection in Thau
