What are the main environmental factors that affect the growth and reproduction of pleated oysters?

Oyster growth is related to species, age, foodstuffs, and environmental physicochemical factors.
Divided by growth, physical can be divided into two types: one is that the growth of shells is basically completed within one year, and little or no growth grows later, such as pleated oysters; the other is after several years of fixation. Shells can continue to grow, such as near the river oysters. In general, the growth rate of shells is inversely proportional to the age. The older the growth, the slower the growth. Various kinds of oysters grow particularly quickly within a few months after seedling attachment. If the pleated oysters are only fixed at a length of more than 300 micrometers, after 3 months of growth, they can reach about 5 centimeters, and the average monthly increase is more than 1.5 centimeters. Subsequent monthly average growth rate slowed down, but some time later, especially in the two to three months before sexual maturity, the growth of software was more.
Foodstuffs are a major factor in the growth of oysters. The oysters are fed by filtering seawater. In the natural sea area, oysters eat on average 16-19 hours a day. In the same sea area, the oysters in the low-tide area have a short drying time. The oysters take a long time to eat, they grow faster, and the flow is smooth. The food brought by the sea water is more, and the oysters grow faster. Production practices have demonstrated that oysters can be obtained in high-yielding and high-quality farmed and fattened oysters on both sides of the Gangdao or low-tide areas. Individuals bred in shallow-sea breeding areas are often bred by individuals larger than the intertidal zone.
Environmental physicochemical factors comprehensively affect the growth of oysters, with temperature and salinity being particularly evident. In four distinct seasons, the growth of oyster shells is clearly staged. When the water temperature drops below 5°C, the growth of the shells is almost completely stopped, which is called rest period. Above 6 °C, oysters grow and eat, known as the growth period. In the proper temperature range, the growth of shells increases with the increase of temperature. The pleated oysters can only live for 1-2 days when the specific gravity of seawater is 1.001, but the adaptability to the high specific gravity of seawater is stronger than that of Oysters.
