“…In North America, where the ecological requirements of commercial shellfish are quite well known, techniques have been developed for the seeding and on-growing of shellfish spat in restoration programmes (Manzi et al 1986;Marelli and Arnold 1996;Arnold 2001). However, these techniques are species-and site-specific, and may not be able to be applied to other geographic areas.…”

The intertidal cockle Austrovenus stutchburyi, also known as tuangi or littleneck clam, is endemic to New Zealand, where it commonly occurs in sheltered sandflats and estuaries. While it is still abundant in some places, recreational collecting and habitat change have resulted in the losses of shellfish beds. This paper reviews the current status of cockle beds in New Zealand and outlines some of the methods that are being used to try to re-establish them. Cockle populations differ both within and between locations, and recent research suggests that this is often site-specific and correlated with sediment properties, salinity and contamination levels. The role of Customary Fishing Regulations and the management of Maori Marine Reserves in promoting cockles as a sustainable shellfishery is discussed, together with the role of closures. The transfer of adult stock may be the most promising technique for restoration. There is, however, a need to identify the potential risks and choose the sites carefully to ensure that shellfish are sustainable and that they improve ecosystem function.

“…Many environmental and other factors affect the condition and growth of estuarine bivalves, and for this and other species, tidal level and density are amongst the most important (Walker & Tenore 1984, Manzi et al 1986, Dobbinson et al 1989, Arnold et al 1991, Harvey & Vincent 1991, Marelli & Arnold 1996. These factors were not considered in the present study because all the shellfish beds were at the same tidal elevation, population densities were similar, and there were few epibionts potentially competing with clams for food (Shriver et al 2002).…”

“…An increase of feed water flow past a filtering bivalve leads to an increase in the absolute uptake of particulate matter because the depleted water is more rapidly replaced (Hildreth & Crisp 1976;Mohlenberg & Riigard 1979;Claereboudt et al 1994). Some studies indicate that growth is enhanced by increased flow because of the increased food fluxes (Malouf & Breeze 1977;Manzy et al 1986). Higher water flow rates resulting in higher filtration rates have been found by Walne (1972) using Ostrea edulis, Crasostrea gigas, Mercenaria mercenaria, and Mytilus edulis; by Lam and Wang (1990) using C. virginica; using C. belcheri.…”

Juveniles of hatchery-reared oysters (Crassostrea belcheri) were grown in a semi-closed recirculation system at water flow rates of 0.5, 1, 2, and 4 l min −1 . Growth rate increased with increasing water flow rate (P < 0.05) over four weeks. No significant differences in survival were found among water flow rates (P > 0.05). Four stocking density treatments were compared: 4, 8, 12, and 16 juveniles cm −2 . Stocking density affected the growth of animals, with higher growth rates obtained at the lower densities. Optimum stocking density based on growth rate was obtained for oysters at 12 juveniles cm −2 . Survival of oysters declined with increasing density (P < 0.05) over four weeks. Among the treatments tested, a water flow rate of 4 l min −1 and stocking density of 12 juveniles cm −2 are suitable for nursing hatchery-reared juvenile oysters (C. belcheri) in a semi-closed recirculation system.
