First, the time to go to sea.
1, spring
Spring in Dalian is usually between March and May, when the sea temperature rises gradually and everything recovers. In this season, there will be many marine life on the beach in Dalian, such as conch, sea rainbow and sea urchin. In addition, there are many seafood in Dalian in spring, such as oysters and marine fish, which are very suitable for fishing.
2. Summer
The summer in Dalian is generally between June and August, when the seawater temperature reaches the highest value. In this season, there will be many shellfish and seaweed on the beaches of Dalian, such as scallops, conchs and kelp. In addition, there are many seafood in Dalian in summer, such as abalone and sea cucumber, which are very suitable for catching the sea.
Second, the best time to catch the sea.
1, around the second and fifteenth day of the lunar calendar
In other words, there are two big tides every month, 9 am and 3 pm respectively. At this time, the seabed exposed by low tide is called "beach".
2. From the twelfth lunar month to the twentieth lunar month.
Near dawn, the tide recedes and then rises again. The first day to the fourth day of the lunar calendar is the spring tide day, which is most suitable for catching the sea.
Precautions for catching the sea:
1. The Yellow Sea includes the waters around Dalian (along Binhai Road, Lushun South Road, Jinshitan and Dalian Bay).
2. The Bohai Sea area is mainly along Lushun North Road (Daheishi, Chessboard Mill, Xiajiahezi, etc. ).
3. The interval between two high tides in 24 hours a day is 12 hours, and the interval between two low tides is also 12 hours.
4. The time spent in the process of high tide and low tide is basically the same (6 hours 12 minutes), and the tidal interval between two days is generally delayed by 48 minutes.
As the tide is the result of the moon's gravity and follows a fixed period, the tide time will not change with the change of years, so the tide table is universal every year and does not need to be updated.
6. The tidal period is 15 days, so the tidal time on the first day and the sixteenth day is the same, and so on.
7. Tides can be divided into active floods and dead floods. Active flood season means that the tidal range changes greatly and the water flow is stable. At this time, the fish are more active and easy to take the bait.
8. The news of death means that the tidal gap has not changed much and the current is relatively poor. At this time, the fish are not very active and it is not easy to take the bait. Generally speaking, the spring tide is an active flood season; Small tides are stagnant floods; There are active floods and dead floods in the middle tide.
