What are the environmental requirements for clam farming?

Clams are a kind of shellfish with high economic value. They enjoy a high reputation in the market. They have the effects of clearing heat, detoxifying and moistening the lungs. They are a kind of aquatic products with huge consumer demand. So, how to breed carp in the future? Next, let me introduce the breeding technology of the breeding system to you.

Clam farms should be located in areas with convenient transportation, far from pollution sources, gentle winds and waves, stable tides, flat terrain, low tide time of no more than 4 hours, stable sediment, sediment concentration of 70% to 90%, low water level, or ponds and beaches in reclamation areas with suitable bottom and water conditions. Drain the pond water and stock the seedlings one month before disinfection, isolate the pond bottom for 15 to 20 days continuously, and evenly sprinkle 15 to 20 kg of bleaching powder with a chlorine content of 25% to 28% per mu over the entire pond.

The disinfected seawater is filtered with a 0.25mm filter, soaked in water for 2-3 days, drained, and repeatedly soaked and drained 2-3 times. After cleaning, the water depth is 30-50cm. Use 0.5-1g urea and 0.1-0.5g superphosphate per cubic meter, once every 2-3 days, to make the water light brown for the growth of clams. The breeding season for breeding clams is in early summer, which varies with species and regions. Liaoning, Shandong and other places ovulate in July-August; Jiangsu, Zhejiang, Fujian in June-July; Guangdong and Guangxi in May-July. The sea surface temperature during the egg stage is about 27℃-29℃, and the optimum temperature for embryonic development is 24.9℃-31.4℃, with 26℃-28℃ being the best. The suitable environment for seedling survival is a sand content of not less than 75%, the sand quality is the best, and it has strong adaptability to low-density seawater.

Clams are a common seafood. Here are some tips for growing clams:

1. The breeding site should be selected in the mid- and low-tide areas with a sand content of 70% to 90%;

2. When sowing seeds, it should be done at low tide or when the tide is slow, which can avoid the loss of clam seeds;

3. The seedling density is determined based on factors such as the size of the clam seedlings, the height of the tidal zone, and the bottom conditions.

When breeding clams, you should choose tidal flats. The environment should be very good and free of pollution. You should take measures to prevent escape, disinfect regularly, change water regularly, sow in April and May every year, and the density should not be too high. After sowing, you should feed regularly, and you should also observe the survival rate of the gali, and vaccinate regularly to prevent the clams from getting sick. Pay attention to the time of clam reproduction. During the reproduction period, you need to pay strict attention to the water temperature, which should be between 26 and 28 degrees Celsius. In addition, pay attention to the sand quality of the clams, and ensure that the sand content is above 75%. You should also disinfect the environment in which the clams live in a timely manner.
