    ?

    Weekend is the day that the students have been looking forward to for a long time. Although they are still forced by their parents to do homework these two days, at least they don't have to go to school, listen to the teacher's criticism, and have extra time to play.  Even a studious student like Zhu Yan threw away his books and went to play happily.

    Yan Zhongsheng finally did not break his promise, and set off to Sea World early in the morning with his wife and children.  Although Yan'er has been to the sea world many times, she always feels that the seabed is the most mysterious, and it always carries magical power, which makes her want to explore more ocean knowledge.

    She was originally curious, full of curiosity and interest in everything in her life, and the knowledge in books was far from satisfying her greedy heart.

    There are a large number of fishes of different shapes and colors in the ocean world, as well as penguins from afar, and coral reefs on the bottom of the ocean.  For close contact, you can also watch excellent programs such as dolphin performances, human-shark dances, "mermaid" performances, artificial snowfall, and 100-meter diving.

    Every time she watched it, Zhu Yan couldn't help but admire the magic of nature. She was full of confidence in life, and she was full of hunger for knowledge. She always felt that she knew too little.

    "Dad, why can the dolphins understand the trainer's whistle and body movements?" She blinked her beautiful double eyelids and asked her father with twinkling eyelashes.  Yan Zhongsheng fondled her little head, "It's the dolphin master who is so powerful that he can make the dolphins obediently obey her."

    Zhu Yan pouted displeasedly, "If Dad doesn't know, he just doesn't know, and he's coaxing me! Hmph!"

    Yan Zhongsheng smiled at Zhuzhu, and Zhuzhu said, "Isn't Yan'er very easy to learn? After watching the dolphin show for so long, you should know something about dolphins, right?"

    Zhu Yan smiled and said, "I like dolphins very much, so I searched for dolphin training on Baidu. In fact, animals have two kinds of intensive training, namely rewards and punishments. And dolphins are the only one that cannot be punished."  Animals are trained only with positive affirmative reinforcement methods. For newly captured dolphins, they send out signals such as blowing whistles every time they are fed. When they are found to be facing or swimming towards the trainer, they send signals and give them fish at the same time.  Eat. When the animal establishes a solid conditioned response to the connection between this signal and food, it can use this signal to instruct the dolphin to perform a certain action. If it is right, it will be rewarded with fish immediately;  It eats fish, and the trainer turns its back or leaves the field to show punishment. You can first train the dolphin to come to the trainer when it hears the signal, grab the fish from its hand, stop in front of the trainer, and allow the trainer to touch it, etc.  The next step is to train it to swim to and press an object with its beak. For example, let it press a paddle. During training, first touch its beak carefully with the paddle and send out a signal; then gradually put the paddle on the other  In a small range in front of the beak, let the dolphins press it when they hear the signal. After the dolphin has mastered it, you can place the paddle anywhere in the pool, and the dolphin will swim over and press it as soon as it hears the signal.  Dolphins must be trained with patience and not in a hurry. To train it to perform certain complex movements, it must be done step by step, and each step must be repeated and consolidated for a long time. Otherwise, too fast progress will cause the dolphin to panic.  Confused and flustered, the time spent on training is actually longer. The movements that the animal has learned must be repeated again and again, so that it builds confidence in the requirements of training.

    In order to train dolphins to obey commands and conduct various scientific experiments in the sea, it is necessary to start training in the pool first and gradually transition to the sea.  First of all, in the breeding pool, use the underwater sound as a call signal to train it to return to the trainer immediately when it hears the call signal given to it under any circumstances.  Then it was trained to follow the signal to go back and forth through the gate on the pool.  After the dolphins have mastered it, they can be transferred to pens in harbors, lagoons, etc. to repeat the training, and finally they are put into the sea.  After arriving in the sea, first train it to follow the boat according to the command, and then do other training gradually.

    As for training dolphins to act as "police dogs" and manage artificially raised fish schools in the sea without eating the managed fish, the work is even more difficult.  First of all, we must start with the selection.  It is necessary to choose a species that can defeat any large-scale fish and beasts (such as sharks, sea beasts, etc.) that endanger fish schools, and has a sensitive response ability. Among dolphins, killer whales are the most important.  The selected killer whales are raised for 2-3 generations. From the grandchildren onwards, they are not fed raw fish, but only artificially prepared meat.  At the same time, train it, cooperate with water sound, train it to understand the signal given to it, and answer with the correct action.  After it is placed in the sea, it must be able to return to the command ship frequently to prevent it from being far away.  In order to make it easy to recognize the fish under management, killer whales should be trained to have a clear division of labor.  Some are in charge of this kind of fish, some are in charge of that kind of fish;  If an excellent killer whale is trained, the annual catch can rival that of a thousand-ton fishing boat.  (The above is from Baidu)

      Zhu Yan talked eloquently, and Yan Zhongsheng and Zhu Zhu were taken aback for a while. Although Yan Zhongsheng and Zhu Zhu had watched the dolphin for so long, they had never thought about how it obeyed the trainer, but  Everyone is here to enjoy the beautiful performance of dolphins. How many people will pay attention to the hard training that dolphins have undergone before performing on stage?

    Zhu Zhu was so excited that her eyes filled with tears. Yan'er was only in the sixth grade of primary school. She knew that Yan'er was smart and had a photographic memory.  The Internet age is simply a treasure trove for a daughter with a strong desire for knowledge.  A lot of knowledge comes from the Internet, which used to be a matchmaker between her and Yan Zhongsheng, and is now a treasure trove of knowledge for her daughter.  The excitement and joy she couldn't express in her heart quickly wiped away her tears, "Yan'er is really hardworking and studious, my mother sighs."

    "Mom, you made fun of me." Yan'er said modestly.

    "Look at you making mom cry." Yan Zhongsheng lightly reprimanded, Zhu Yan stuck out her little pink tongue, "Mom never cries, today I'm so touched!"

    "There is no better mother than a daughter." Zhu Zhu laughed.

    "The wise daughter is Mo Ruomu." Zhu Yan joked, and all three laughed.

    Then I watched the performances of other animals. Zhu Yan screamed excitedly because of the wonderful performance. She has integrated herself into this beautiful performance. Art is always the soul of human wisdom, and knowledge is the soul of human beings.  crystallization.  (Remember the site URL: www.hlnovel.com
