Comparative Study Of Seed From Northern And Southern Hatcheries, Joshua Merritt, Paige G. Ross

Reports

Seed from Northern and Southern (hereafter called local) hatcheries was procured in May 2000. Oysters delivered by the Northern hatchery were on time and of the desired size ~3mm). Seed from the local hatchery, however, arrived several days later and were too small to go into field nursery containers and were subsequently held in upwellers and then transferred to the field nursery gear. Figure 1 shows growth as measured by mean shell height (mm) for both strains. Note that the local seed took N20 days longer to reach grow-out size (indicated by first sieve).

Artificial Reef Grow-Out, Jeff Hammer

Reports

The purpose of this project, was to address the possibility of improving upon the cun-ent grow out procedures currently being used by the oyster aquaculture industty. I.e. Taylor floats - Rack and bag.

As stated in the proposal, the current adopted method of raising oysters is to use Taylor floats. This method has proven to be effective in producing market sized oysters in 1- 2 years, although intensive labor cost and high fouling rates decrease profit margins considerably. Also the availability of suitable sites is now under increased regulations and is not welcomed in some waterfront communities.
