Oysters

The term oyster covers a number of groups of marine bivalve molluscs which grow in sea They live only in salt water ( containing 30 to 32 grams of salt per liter (g / l) or less ) and found in all seas.

The oysters are very popular in terms of gastronomy and their ready aphrodisiac properties . Most of the annual production is sold during the holidays season .

Culture>>>>

The culture of oysters is called oyster and is practiced on the coasts.

Four breeding methods are known:

suspended in tables ( in the Mediterranean)
deepwater
ground
raised in

Bottom culture of Pacific oysters>>>>>

This more traditional farming ( mostly used for oysters ) is practiced in deep water, it is to disperse the oysters on the ground ( sand or mud) on farms that do not find themselves at low tide and harvest oysters with a dredge .
Big advantage oysters will grow better because constantly in the water, they breathe and eat more .
The default and is sized for oyster is that oysters are too exposed to predators like the Royal bream or stripes . They are not protected by pockets .
These fish can crumble oyster shells and devour an entire breeding season in a few weeks .

Bottom culture of oysters>>>>>

The most common method of farming is practiced in shallow water uncovered at low tide : the foreshore.

It is much more modern and was born in the year 1970. It is to have oysters pocket on iron tables 80 cm high , with 4 hooks of different model , different diameters and colors.

Tides can work in dry semi / or dry on these parks.

The advantage is that the bags will protect the oyster predators and will be easier to work with . It should be against by splitting the oyster bags every 6 months , as more oysters are packed , they will grow less .
This is why at each age is a size oyster mesh pockets for easy insertion of the currents in the pockets that provide food and oxygen to oysters.

This operation also allows you to change resawing oysters park according to their size and their status grows . It will also turn the oyster bags every month of the summer to well spread in their pocket and at the same time remove the algae that grow below the pockets that spoil their weight.
Adult oysters feed on plankton (phytoplankton and zooplankton ) which are small organizations that follow the currents. Oysters filter an average of 10 liters of sea water per hour.
