On April 21st, we took our luggage and embarked on the road of internship at Photosynthesis with joy. Time flies, and it has been 25 days since I came to the coastline. I would like to share with you the experience of the internship during this period, and let this youthful years accompany us to move forward.

The staff of the coastline branch are very enthusiastic and simple, and give us meticulous care and help in life and work. There are many people I want to thank. Thanks to Brother Liu for his careful answers to questions during the production process; to Brother Qiang for his careful guidance on the internship; and to Sister Wang Ping for her meticulous care in daily life. What impressed me the most was Manager Li, the commander-in-chief of the branch. With more than ten years of practical experience, he was very thoughtful when considering various events. I remember one time, when the crab fry was in the Z1 stage, and the pH of the pool water was in the range of 8.90 to 9.08, everyone was very worried about this. In those days, we saw the manager carefully patrolling the pools on a motorcycle. As soon as we returned to our residence after the PH test in the morning, we saw the manager anxiously waiting for us at the door and asked us carefully about the pH of each pool. After knowing the specific situation, the pond bottom raking was started on the second day, and the pond was splashed with acid to control the pH. When monitoring at noon on the third day, it was found that the pH of all the ponds had dropped to a safe range. After the manager saw the data, his face showed a smile when we first met, and we also smiled comfortably. At this time, the sky was exceptionally blue.

During this period of time, I deeply discovered that raising crab seedlings is like raising babies. Not only can we not be sloppy, but we also need to have the spirit of perseverance regardless of weather. From Z1 to Z3, we got up before five every day to quantify the rotifers in each pond. For a family like me who has difficulty getting up, it is difficult to get up, and getting up early is even more difficult. For this, I have tried many methods, such as drinking more water before going to bed, setting an alarm clock, etc. Finally, with the help of my classmates, I found a very good method, which is the Mindfulness Method. Before going to bed every day, I have to repeatedly tell myself to get up early tomorrow, to be rationed, and not to let the crab fry go hungry. On the way to get up early in the morning, the corners of my mouth are always raised whenever I see the dazzling sun.

Here I saw live flea-like larvae, rotifers and Euglena in the water, etc., but I could only know them by looking at specimens or pictures in school. In addition, I temporarily raised two brine brine shrimp. Every day at noon, I would use a microscope to observe whether its bait was sufficient. Sister Wang told us that there is a kind of crustacean in the local area, which looks like a small crab, commonly known as burnt clips. They can be caught and fried when they climb to the shore at night. So that night, we grabbed two large plates with flashlights, and the smell of the stir-fried roast clips made us rush back to the cafeteria the next morning. When I caught it, I found some burning clips holding the eggs, and the eggs were observed under the microscope and found that they were still in the stage of cleavage. The river crabs were already young at that time, and they were in the Z1 stage, which calmed my worry about whether the burning clips and the river crab seedlings would be mixed in the ecological seedling raising. In addition, the company also invited two professors, Lei Yanzhi and Li Yonghan, to the internship base. They gave us lectures on the impact of calcium carbonate supersaturation on water quality and related knowledge of aquatic biology, which can be heard during the internship. The lectures given by these two seniors in the aquatic industry are really something to be proud of!

My childhood was spent in the city, and this internship made up for many of the joys that my childhood lacked: being able to run wildly in the muddy mud after the rain, witnessing the construction of the swallow's nest step by step, and sitting quietly on a windy afternoon Watching the spring reeds swaying in the wind on the bank of the earthen pond is also a different kind of joy.

I hope that other interns can also gain fun from this internship other than aquaculture knowledge. I hereby offer my motto: Today, if you do what others don't want to do; tomorrow, you will do what others can't. I would like to share with you all.
