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.

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

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 ...

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.

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 ...

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.

Improving the efficiency of wild Pecten maximus spat collection: potential effects of spat bag design and of species temporarily settling in spat bags

Aquaculture, 1998
Abstract The single and combined effects of external bag size and external bag mesh size upon the collection and retention of wild King Scallop spat ( Pecten maximus L.), other scallop species ( Aequipecten opercularis ) and other animal groups were investigated in a collection area off the west coast of Scotland.

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
