How to raise oysters

There are four ways of raising oysters: cuttings, hanging, flat hanging and floating shed. The first three are raised in the intertidal zone, which can be exposed to sunlight at low tide, and the last one is kept in the deep sea all the year round.

How to raise oysters

I. cuttage type

In the earliest practice, the raw oyster shell was directly tied to the split bamboo slices and inserted on the beach to let the oyster seedlings attach naturally, saving cost and manpower, but the growth rate was slow, the efficiency was low, and few people used it at present.

2. Flat hanging type

Using bamboo as the base post, plus two rows of crossbars, the oyster string is hung parallel between the crossbars, which is suitable for use on the beach in the shallow intertidal zone, about one meter.

Third, sagging type

Similarly, the base column is set up first, and then a rectangular grid is made of bamboo or plastic pipe above, and the oyster string is hung vertically, which is perpendicular to the current and increases the chance of feeding. The depth of the sea water in the culture area is deeper than that in the flat type, mostly in the inner bay and tidal ditch.

Fourth, floating shed type

Directly use Baolilong as a floating device, connect horizontally with a thick rope in the middle, and then hang several strings of raw oysters vertically on the thick rope, also known as breeding along the rope, the hanging depth is relatively deep, up to 3 stories high. More vulnerable to flatworms.
