Habitat enhancement results from chapter 4 (2005). 2015-07-14T01:20:00 creation 2015-07-14T01:20:00 revision Experimental plots were located in Tasman Bay at four sites (A,B,C and D, 1 ha in size, separated by >2 km). To compare oyster settlement among 3 enhanced habitat shell density treatments, at each site, 9 plots comprising 3 replicate plots of 3 treatments were set up. Treatments comprised: dense shell piled to a height of ~0.3 m above the substratum; scattered shell and non-enhanced seabed as a control. Treatment plots were 4 m in diameter and located 30 m apart within the 1 ha site. Broodstock was added to plots C and D to address this aim (see below for specific aims of the project). Field studies were conducted between October 2004 and May 2009. To research the effects of habitat enhancement on oyster recruitment. Specifically looking at the following. 1. The suitability of oyster shell, scallop shell and mussel shell as settlement substrata for oyster spat. 2. Comparing oyster settlement among enhanced habitats. 3. Measuring the effect of adding broodstock to enhance habitats. 4. Quantifying changes in availability of settlement surface on enhanced habitat. 5. Estimating growth and time to harvestable size of oysters, as well as survival rate and predator present on enhance habitat.
