Abundant fish production

Dongsha sea area is adjacent to the bitter water ocean, and the upward distance of tidal waves is very close. Every day, the overwhelming strong tidal waveform has become a shocking sound with distinct rhythm. People who have an indissoluble bond with the sea have a special liking for the sound of sleepless waves, saying that it is a "spawning song" given by the sea to marine life. Due to the dense submarine waterways, abundant plankton and moderate water temperature in Dongsha, hundreds of benthic organisms such as fish, shrimp, crab and shellfish come here from March to June every year to lay eggs and fatten in the surf nest in the sandbar. During the calm tide, if you take a boat trip to Dongsha Sea, the scene of layers, pieces and groups of newborn little creatures scrambling to snuggle up next to "mother fish", "mother crab" and "mother shrimp" will definitely make you ecstatic. Red shrimp flooded in this sea area in March; Meitou and Fengwei floods in April; Catfish and bamboo pod fish flooded in May; In June, pomfret and yellow mushrooms flooded; In July, American fish and swimming crabs flooded; In August, jellyfish flooded; Barracuda flooding in September; During the autumn fishing season in June 5438+ 10, fishing boats returned with full loads for many years, and fishermen's money bags were bulging. In particular, this sandbar sea area has become the main producing area of "soft gold in water-Monopterus albus" and the protected area of "giant panda in water-Chinese sturgeon".

Beautiful scenery

Walking around Dongsha, listening to the beautiful songs of Haitao and seabirds, and witnessing the beautiful movements of seabirds and Haitao embracing each other and dancing are exciting. There are more than 200 species of birds that take the beach as their "home" and Tao Wei as their companion, and thousands of seabirds live close, harmonious and friendly on the island. When the waves sound, they spread their wings one after another; When the waves stopped, they went to the beach to feed together. Life is so full and leisurely. Black-billed gull of the island family is a rare seabird in the world, which is particularly concerned and protected by people. However, black-billed gulls are never proud, never coquetry, never weak, and they like to kiss stormy waves; They like to fight against storms, and they like to travel in colorful clouds and sails. Especially in the dangerous wave valley, the difficult coherent movements such as diving, predation and jumping are beyond the reach of other seabirds. "Black-billed gull is also the information messenger of our fishermen. From its different chirps, we can know the weather changes, the size of tidal floods and the urgency and intensity of tides. " Fishermen sat on the bow deck, competing to praise the black-billed gull who lived together day and night. When I was young, Wang Yibao, a Taiwanese working in Dongsha, came back last year? When I was visiting relatives in Hong Kong, I said emotionally that whenever I saw seagulls coming and going, my homesickness grew stronger and stronger at the seaside of Taiwan Province Island. The stormy waves in the Taiwan Province Strait can't stop seabirds from going back and forth, and they can't stop thinking about reunification.

Scientific research value

The sound of the waves is rough and long. The waves in Dongsha sound like songs and dreams. Affectionate and intentional waves have brought bumper harvest news from generation to generation, with more fish and shrimp and bumper harvest in flood season. The heartless and unintentional sound of the waves once again brought the bad news that his wife, children and children died in the crowd rushing to the sea. According to statistics, during the 55 years from 1925 to 1980, there were 45 shipwrecks in Dongsha and its adjacent waters due to irresistible natural disasters, and 2 19 people died in the sea.

The exciting sound of the waves calls for the desire of scientific utilization and good protection. As early as 1979, in order to study the reasons for the formation of Dongsha Island and the geology, geomorphology, tides, meteorology, biology, environment and other disciplines in this area, the Dongsha Observatory was built, and uninterrupted scientific research work was carried out, which accumulated rich scientific research materials for the construction of "East Jiangsu at Sea".

The ancient Dongsha, the young Dongsha, is passionate because of the sound of the waves; She was shocked by the sound of the waves; She was magnificent by the sound of the waves. She dedicated a song that people can never finish reading, singing and listening to.
