TERA Gold, attached little shell top. The quality is hard, section layered, white. Odourless, slightly salty taste. Indications of pinggan Qian Yang, solid hard, soft, acid. Crassostrea five breeding methods, applied to wave of calm, slow speed, high salinity, soft mud or silt sediment in the Bay. This production to the local culture of oyster seedlings. When culture is done by oyster bamboo sparsely for the benefit of maleOyster growth. Immobilization of oyster seedlings in the spring of that year to the end of harvest.
Immobilization of oyster seedlings to be deferred to the following year in the fall to harvest in winter. Second, Crassostrea dropped by habit 1. raft culture: This applies to rush more than 4 metres water depth, wind and waves in the calm Bay, structures vary depending on the size, there is no uniform specifications. You can usually use a circle and tie of Phyllostachys pubescens, 5x10 m,10x10 m, 6~9 a floating barrel for each raft or float buoyancy and anchoring Harbour, hanging on the raft of picking seedlings develop. 2. the longline cultivation: this type have a greater ability to resist wind, apply to offshore aquaculture, the basic structure is made of two pieces of 2 cm in diameter, length 70~75 m spokenearaxle rope tie, anchored on each end, spokenearaxle ropeConnection to 12 equally spaced on a polyethylene float, attachment of picking seedlings, suspended in spokenearaxle Wire feeding. 3. the hurdle-culture: this method applies to the smaller Beach slope, rush 2~3 meters water depth, sediment mud or sand and waves of calm sea.
Harbour setting up timber or concrete piles, with erection of bamboo grid above, hanging on the gate of picking seedlings culture. In the habitPeriod, must manage day-to-day work, such as moving stone, floods, winter, clearing the vermin, such as finishing and refurbishment of floating raft. Three Oyster tateishi, long habit of oyster seedlings taken by using this method in-place continues to develop, if Oyster seedlings have solid and dense, to appropriately sparse. Erected in the sea area of the stone pillars, generally does not move the position, as a permanent farming equipment in the area. CollectionWhen shoveling down oysters from the stone pillars, Su meat open shell returned to the shore. Four, long bridge-forming method using the method of the oyster to oyster
TERA Power Leveling, after 1 month of training, individuals grow, you want the stone back keep-out arrangement, so as not to affect growth. When the drain line, 6~7 pieces of stone make up a group, group of stone into a long column, 50~60 cm group spacing, column spacing 1~2 m, after a period of time after farming, Oyster stone Nightside interchangeable with side exposed to the Sun, making Oyster growth evenly on both sides, to a late harvest.
Five, long Oyster stone formed the habit of this law applied to sediment intertidal and subtidal areas of hard, stone or large stones for the base of selection of boxing. 1.-Star: stone evenly dispersed in the form Oyster sites, investment per Mu Oyster rocks 3,000~5000 block.
This applies to the Sham Shui Po District.
2.-clubs: 5~6 Oyster stone heap into a heap, plum-shaped, each heap space 30~50 cm, in form fields scattered form. 3. the determinant: Oyster Ishinari lines arranged in a form field, and each row width of about 30~60 cm, equal to the length and width of oyster, leading 50~100 cm.
