First, the oyster natural sea area half artificial seedlings (B) Grasp the time for picking seedlings and put them in time Do a good job in forecasting seedlings, trawl from the discovery of a large number of oysters ovulation, check the larval development and quantitative changes, generally 25 to 60 shell top larvae per cubic meter of water, the water temperature at 22 ~ 27 °C, up to the production of attached Seedling density requirements (seedling time is generally from late April to late May). According to the time of harvesting seedlings in the sea, shells can be planted in time to collect seedlings. The shell string should not be stacked too high or too thick. It is too easy to attach barnacles too thick, and is too thick to attach seedlings unevenly. (III) Strengthen the management of seedling collection and timely raising and cultivation Always check the firmness of the seedlings and flush the seedlings with floating sludge to prevent the seedlings from being covered and suffocating. After harvesting seedlings to meet the needs of feeding and growth of seedlings, seedlings should be reared in time to reach 0.5 cm in order to promote their growth and reduce death. (B) Strengthen the management of cultivation Frequent inspections of the sea, safety inspections of the breeding facilities, and timely prevention measures should be taken to prevent problems in order to prevent anchoring of the piles and string breaks. Clean up the string in time to lift the string and prevent it from colliding and falling off. Late oyster rearing is performed alternately with fullness and weight loss. It is necessary to conduct inter-annual harvesting or harvesting at the end of its full-blown period. At the same time, it will be listed in a balanced manner according to market conditions to increase income.
POE (Power Over Ethernet) refers to the use of IP-based terminals (such as IP telephones, wireless LAN access points, and network cameras) without any changes to the existing Ethernet Cat.5 cabling infrastructure. etc.) The technology that can provide DC power for such devices while transmitting data signals is a switch that supports Power over Ethernet.
At the same time, POE is also called Power over LAN (POL, Power over LAN) or Active Ethernet, sometimes referred to as Power over Ethernet, which uses existing standard Ethernet transmission cables to transmit data at the same time and the latest standard specifications for electrical power and maintain compatibility with existing Ethernet systems and users.

(A) choose a good picking area, set picking frame
The nursery usually chooses small winds and waves, smooth flow, flat terrain, sandy muddy beaches, and suitable for seedlings in the middle of a low-tide area with stable seedlings (tidal dew for 1.5 to 2 hours). The bed height of the seedlings is controlled to be about 50 cm from the bottom, and the top of the shell string is not to exceed 60 cm. It should be set up well before picking seedlings in the lower sea.
Second, oyster sea area cultivation (longline culture)
(a) timely adjustment of the water layer
In the early stages of planting, the seedlings are small and light, which is a time when the barnacles proliferate. Floating floats should be kept to a lesser extent, so that the aquaculture water layer can be deeper, and sluggish winding and barnacle attachment can be reduced. With the growth of oysters, the load is getting heavier and heavier. The number of floats should be increased in order to make full use of the surface-rich food organisms and promote the growth of oysters.
(3) timely harvest
