——The 8th General Exhibition "Social Practice Report"
Excellent works recommended
Opening Remarks:
Tianjin is located on the west coast of the Pacific Ocean, on the bohai Bay, forming a long coastline of 153 kilometers in the long intersection of land and sea. The Bohai Sea is known as a "natural fish pond" and is rich in marine products such as fish, shrimp and shellfish. There is a great variety of marine life here. The sea here is closest to Beijing, but we don't know the richness, beauty and sorrow of the sea. Today we follow the popular science wanderer senior marine biologist to take a boat out to sea, explore the life of Bohai Bay, learn marine protection knowledge, and understand the most important ecological field on the earth.
Preparation for the event:
Today is May 20, 2018, the weather is a little gloomy, but it did not affect my mood at all, I got up very early, because I was going to participate in the Bohai Bay biological expedition, I was very excited, on the bus to the event site, I gave myself a name of "lilac".
Coming to today's event site, my heart is full of expectations, my friends and parents have come, and it seems that everyone has a strong interest in marine creatures.
Coming to the deck of today's fishing boat, my mood is so relaxed, looking at the surrounding fishing boats and soaring seagulls, as well as the flying five-star red flag, I am proud of the motherland!
In the cabin, marine life experts explained to us the general situation of Bohai Bay, the terrain, the types and habits of marine life, and I had a preliminary understanding of this ocean.
Participation:
The fishermen's uncles have already sown the fishing nets when we listened to the lesson, and now they have begun to collect the nets, and the fishing nets are so big! Experts say that collecting fishing nets is also a technical activity, and the country attaches great importance to the sustainable development of the marine environment, and young organisms will be released back into the sea.
The friends couldn't wait to climb to the stern of the second floor and scrambled to watch the fishing nets gradually being put away, and I think they, like me, hoped that more marine life would be salvaged.
Fishermen and marine life experts are counting and cleaning the marine life on board, and there are a lot of them! There are fish; there are shells; there are crabs, looking forward to the explanation of expert teachers.
After the sea creatures were cleaned up and classified, we came into contact with them so closely for the first time, feeling the diversity of life and the greatness of life.
Charm shows:
The Japanese Kanko crab (scientific name: dorippe japonica) is an animal of the genus Guan Gong in the family Kwan gong crab family. Distributed in Japan, Korea, Taiwan Island and Chinese mainland Guangxi, Guangdong, Fujian, Zhejiang, Jiangsu, Shandong, Liaodong Bay, Liaodong Peninsula and other places, the living environment is seawater, mostly in the intertidal zone and nearshore water depth of 20-130 meters of sediment bottom.
Flounder, also known as flounder, plate fish, and partial mouth fish, inhabit the sandy bottom of the shallow sea and prey on small fish and shrimp. They are particularly suitable for benthic life on the seabed. Due to their flattened bodies. The eyes are on the same side of the body, and the color of this side is well matched with the surrounding environment; the downward side of their body is white. Flounders have very fine scales on the surface of their bodies. Flounders have only one dorsal fin, which extends almost from the head to the caudal fin.
Gobies live mainly in the seawater and are a small carnivorous fish, with most species (about 700 or more species) belonging to the gobies family. They are characterized by an elongated body with two vertebral fins. The first has several tiny spines, a series of small senses on the head and sides, a rounded tail, and bright colors all over the body. Most adult fish are about 10 cm long. The most prominent morphological feature of gobies is the healing of their ventral fins into a suction cup.
A general term for the drum shrimp genus of animals in the family Drum shrimp family. The eyes are completely covered by cephalothorax. The first pair of footlets is particularly strong, pincer-like, asymmetrical left and right, and the male is stronger than the female. When living, there are many obvious patterns on the body, especially the bright drum shrimp, and the body color is bright and beautiful. The breeding season of drum shrimp is in autumn, and the eggs are laid and held between the female's abdominal limbs until they hatch. When the drum shrimp encounters the enemy, it opens and closes the finger of the big bird, and makes a sound like a small drum, so it is called a drum shrimp.
Rating:
At noon today, the fisherman's uncle processed the seafood we bought in the market in the morning, made it into delicious food, replenished our energy, and continued to listen to the teacher's lectures. The creatures we salvaged have been released back into the ocean.
The friends sat around the table, listened to the explanations of biological experts with great interest, and felt the mystery of the ocean and the richness of life. Today's harvest is really a lot!
Disembarked, to go home, a little reluctant, and Dad to explore the knowledge of the ocean, I hope to participate in similar activities in the future.
On the way back to the car, I looked out the window and thought deeply: we humans should know more about the ocean, better protect the marine environment, and create a harmonious ecological world.

Conclusion:
Today's event is over, but it has sparked my keen interest in exploring the field of science. I think: we should continue to discover and study the mysteries of the marine field for the benefit of human society, and at the same time we must protect the marine environment and create a harmonious ecological world.
