"Hello, Dr. Griffin, Dr. Liu, and Professor Zhu." Lu Jingyi and Yu You greeted several marine experts one by one under Ouyang Hui's introduction.
"Hello." Dr. Griffin is about sixty years old, energetic and talkative.
"These are the dolphins and killer whales that our aquarium is planning to release." Ouyang Hui guided, "4 dolphins and 2 killer whales."
Dr. Griffin said: "With the two dolphins and one killer whale we brought, the task is a bit heavy."
Several dolphins and killer whales have completed physical examinations and will undergo several tests before being released, mainly on speed, eating status, mental state, etc.
The keeper picked up a fish from the barrel and threw it into the water. Two dolphins jumped up one after another and competed in the air. With two splashes, it fell into the water, and then the victorious dolphin stood up, raised its head, and shouted triumphantly at the fish.
Yu You smiled slightly and silently gave it a thumbs up.
The keepers scattered a lot of fish-eating food. The dolphins and killer whales in the aquarium were very active. They would actively fight for each other every time. If they didn't get it, they would warm up underwater, and if they did, their heads would pop up and feed towards them. Yuyou shows off.
What surprised several experts even more was that one of the male dolphins would share the food he grabbed with another female dolphin.
In contrast, the two foreign dolphins and one killer whale were more reserved. They neither grabbed food nor showed any desire to perform. They seemed to be still familiar with the environment.
"Your dolphins and killer whales are in great shape," Griffin praised.
Dr. Liu did not take it seriously: "There are performance training here every day, and they are probably used to this way of eating. But artificial feeding is completely different from hunting on their own, and the latter is the key to adapting to marine life."
"Dr. Liu is right."
Several people conducted several tests one after another and recorded the test results in detail.
Next comes the most critical item: survival practice.
"The ship is ready and ready to go at any time." This ship was temporarily arranged by Lu Jingyi. It is equipped with advanced observation instruments. It can track the movements of dolphins and killer whales and take pictures through locators and underwater remote-controlled cameras. Relatively clear picture.
As the dolphins and killer whales were released into the sea, the ship was also released, and images and observation data were transmitted on the observation screen at the same time.
The two foreign dolphins and one killer whale kept following the ship, while the four dolphins and two killer whales in the aquarium scattered and swam away like wild horses.
Professor Zhu asked curiously, "Were they not afraid at all when entering the sea for the first time?" Then he turned to look at Lu Jingyi and asked, "Mr. Lu, what is the effective distance of the tracker?"
"3000 meters." Lu Jingyi replied.
Professor Zhu frowned: "They swim very fast, will they not escape the monitoring range?"
"Don't worry." It was Yu You who replied.
However, this statement does not reassure experts. The dolphins and killer whales they brought all followed the ship obediently and cautiously explored the new environment. This was the correct way to go out to sea for the first time. How are they like those guys at the aquarium who let themselves go without any scruples? Are they not artificially bred? Is it really okay to act so wild
"Huh?" Dr. Griffin stared at the monitoring screen with great interest, "Look carefully at their movement trajectories."
Everyone came forward and observed for a moment. Dr. Liu was surprised and asked: "Is this a coincidence?"
Although these dolphins and killer whales swam happily, they always moved within a radius of several kilometers with the ship as the center. They moved very fast but did not exceed the monitoring range. They are like well-trained scouts, moving quickly, orderly and without fear.
On the other hand, the other two dolphins and a killer whale were cautious and timid. In Yuyou's opinion, they were not ready to be released. Although they were healthy, they had too much fat and their swimming speed and reflexes were not up to standard.
More than an hour later, Yuyou's babies each found food, but two dolphins and a killer whale from outside swam to the side of the ship and screamed at everyone on the ship, showing no intention of hunting on their own.
Dr. Griffin and others are not surprised that dolphins and killer whales raised in captivity have not yet developed the habit of hunting on their own and need a process of adaptation. The ones in the aquarium are strange. They behaved so "sophisticated" on their first trip to the sea. If they didn't have a background, they would almost suspect that they were originally wild.
"Goyle, go down and try." Dr. Griffin ordered.
"Okay." Gore put on his diving suit, disembarked from the boat along the rope ladder and entered the sea. He led two dolphins and a killer whale to dive into the sea, intending to teach them how to hunt.
Dolphins and killer whales hunt in similar ways, both focusing on chasing, interception, and teamwork. First send out a vanguard to drive the fish into a circle surrounded by companions, and then attack in groups. The difference is that killer whales are relatively ferocious and dare to bite large marine animals.
This time, Gall acted as a vanguard, driving the fish in front of the dolphins and killer whales. They immediately gathered around and chased and bit the small fish that fled in all directions.
Just as Yuyou had judged, they had too much fat, and they were repeatedly frustrated against these agile little fish. After more than ten minutes, his stomach was not full, and he exchanged extremely aggrieved words with Gower. The killer whale even lost his temper and contradicted Gower from time to time.
Everyone saw it funny and said to Gao Er through the communicator: "Gao Er, you are an incompetent father. Why don't you feed your child quickly?"
Gore spread his hands to express his helplessness.
"Hahaha… "
While everyone was laughing, Yu You suddenly said: "Let Gaoer come up first?"
"Don't worry." Dr. Griffin smiled, "Give them some more time, I believe they will learn it soon."
"That's not the problem." Yu You looked out the window and said seriously, "The killer whale is emotionally unstable and may attack Gao Er."
"Don't worry." Dr. Liu glanced at her, "Gao Er is an experienced breeder. If there is danger, he will be able to detect it in time."
"Yes." Professor Zhu also agreed: "Those dolphins and killer whales have always been raised by Gao Er and have never been attacked."
The marine environment is completely different from that of the domestication base. The sea can receive sound waves from various marine creatures from all directions, warning, messaging, threats, fear, pleasure, navigation, positioning, courtship, etc. For those who have never been to the sea, For killer whales, these chaotic sound waves make them restless. Coupled with hunger, emotions are even more uncontrollable.
Yu You's reminder did not arouse everyone's vigilance. A few minutes later, a situation that worried her appeared.
The killer whale collided and slammed into Goyle's head, knocking him several times. Before he could stabilize his body, the killer whale rushed towards him again, opened its big mouth, and bit his thigh.
While everyone was exclaiming, Yuyou quietly let out a sound wave, and the killer whale made a movement, swung its tail, and passed around Gao Er.
"Goyle, come up!" Dr. Griffin shouted anxiously into the microphone.
However, the communicator was damaged in the impact and Gall did not receive the message. Even if he received it, he could not escape for the time being because his head was dizzy and he was under the sea, so his movement was very inconvenient.
