![]() ![]() A 3-dimensional culture unit might be an important advantage for this species regarding territorial exploitation and efficiency of spatial management in the production cycle. We recommend new strategies to improve the actual culture technology for P. Sticks are spaced 1520cm apart and then fixed to the racks. The sticks used for spat collection are separated and laid out more extensively onto the racks. sterna, the Optimal Stocking Density may be higher than the ranges tested in the present study. This method involves keeping the sticks used for spat collection, removing excessive spat and leaving the remaining oysters to mature. Rail cages promoted better survival than sandwich nets. ![]() Advantages in growth were favorable for D50 C only. The change to late culture improved overall response. From the summer of 2002 the Cawthron Institute will supply Pacific Oyster farmers with superior, hatchery reared, single seed spat. The results indicated that growth and survival in nursery culture were not proportionally related with stocking density. The oyster spat were immediately frozen using liquid nitrogen following collection, and stored at 80 ☌ until analysis. It is easy to remove the spat from six-packs as well. The interaction of density and culture device was significant for shell volume at the end of the experiment (F = 3614.14 p F = 8.09, p F = 0.76 p = 0.3). There are currently three categories of oyster culture in Alabama: commercial (including under piers), oyster gardening, and personal consumption. This method involves separating and flexing the hats to remove the oysters. Growth and survival were acceptable regarding routine operations, but variations in this experiment depended on stocking density and type of late culture device. Growth patterns were examined using shell volume (height × width × depth, in cm3). If a farmer uses spat sticks to grow oysters to market size, he or she will need to implement a grading system for separating oysters (those used for roasts as. We studied the long-term effect of nursery culture stocking treatments. We will have a regular supply of spat again starting in the Apr/May timeframe depending on water temperatures. Each artifact received 70 to 75 individuals. Oyster Spat We plan to overwinter and carry a small amount of spat (both diploids and triploids) over the winter months for pickup on an appointment basis. Late culture proceeded from July 1999 to March 2000 in sandwich nets and rail cages. Mexican made NestierTM trays were used in nursery culture from March to July 1999 at four different stocking densities (25, 50, 75 and 100 individuals/tray). Growth and survival of the rainbow pearl oyster, Pteria sterna (Gould 1852), was evaluated in field culture at Bahía de La Paz, México.
