That night, after trading the ratfish, Xiang Yang went for a walk on the beach.
The plankton floating on the sea emits a sapphire blue fluorescence, like a path paved on the water. It looks particularly beautiful, or like a bridge walking out of a fairy tale town, reflecting the stars in the sky.
When Xiang Yang saw this scene, his heart trembled, a cold wave was coming.
Whenever a cold current comes, dinoflagellates and diatoms will float on the sea surface and reproduce in large numbers. When they reproduce to a sufficient number, they will even form algal blooms, causing a large area of surrounding sea water to change color.
Dinoflagellates and diatoms are the lowest-level producers in the ocean. They are the main food source for small fish, shrimps, crabs, and shellfish, and are also the main oxygen releasers in the ocean.
Whenever a cold current comes, tropical marine fish will migrate southward toward the equator. Without harvesters to harvest them, dinoflagellates and diatoms will reproduce wildly until the spring of the following year when all things revive and continue to nourish the ocean.
"It will be difficult to fish in the next few months!" Xiang Yang narrowed his eyes. Most of the marine fish in the north that are adapted to the cold climate will not migrate south because of the colder climate, but the marine fish in the South China Sea that can grow in high temperatures will continue to migrate south to warmer waters when the climate turns cold.
"But it shouldn't have a big impact on me." Xiang Yang's hunting grounds can even extend to the deep sea area ten thousand meters deep. In such bottomless sea areas, sunlight cannot penetrate at all, and the climate is cold all year round.
Xiang Yang took off his coat and wanted to go to the bottom of the sea to take a look.
Before going into the sea, Xiang Yang suddenly stopped again. He saw a starfish with five tentacles lying on a reef exposed above the sea in front of him.
Starfish, also known as star fish, are shaped like a five-pointed star and covered with spines. They feed on slow-moving shellfish and crabs. Every tiny crystal on their spines is their "eye".
Xiang Yang swam to the reef and broke the starfish off the reef.
The starfish has the strongest tentacle regeneration ability among all animals. If any of its tentacles are torn off, it can quickly grow a new tentacle.
Some people may think that this ability of its is similar to that of a gecko, but in fact it is much more amazing than that of a gecko, because not only can the torn part of a starfish grow back quickly, but the torn part can also quickly grow a new starfish.
Starfish are a very important link in the marine food chain. They prey on clams attached to reefs, but they themselves have almost no edible value. Few marine creatures, including humans, will prey on starfish.
However, the medicinal value of starfish is extremely high. It has a calming and soothing effect and can be used to treat a variety of stomach diseases. The most important thing is that it can also eliminate scars to a certain extent.
"Catch some and see if pharmacies will buy them." Xiang Yang took the reef as the center and searched carefully around it.
Starfish are gregarious creatures and can often be found on steep rocks or on the bottom of shallow seas. Spotting one means there are usually a large group of them around.
When he got to the bottom of the sea, Xiang Yang did not see any signs of large groups of starfish living there.
Xiang Yang turned his head and looked at the reef behind him. Starfish often have the habit of leaving the group and crawling from the seabed to the reef to breathe. It seems that the captured starfish wanted to crawl onto the reef to breathe and temporarily leave the group.
If there was only one starfish, Xiang Yang would not be interested anymore. He would just let go and threw the caught starfish back into the sea, then continue swimming towards the deep sea.
After swimming southward for a short distance, Xiang Yang, who was swimming on the seabed, suddenly stopped.
In an area of sea that was relatively barren in the past, Xiang Yang discovered a large number of tropical fish migrating southward.
There are so many sea fish gathered together that it is impossible to count their number or distinguish how many species they are.
All kinds of beautiful, hard-to-see, and strange-shaped sea fish are swimming towards the south.
From time to time, ferocious marine predators would rampage through schools of fish and swallow large numbers of small fish in one bite.
However, these are not the point.
The focus is on the migration of fish. Swimming crabs and lobsters that feed on small fish and scallops are also following the fish schools and migrating south with them.
The huge lobsters that were once elusive can now be seen everywhere.
The swimming crabs lined up in a straight line that stretched as far as the eye could see and moved forward.
"How many swimming crabs are there?" Xiang Yang was stunned. These swimming crabs, which came out in entire groups, had changed their timid nature of the past and were really running rampant in the sea, not afraid of people at all.
Xiang Yang swam to a lone swimming crab that was as big as a small ball and weighed at least half a pound. The swimming crab was holding a one-foot-long sea fish with one of its huge pincers, and was using the other pincer to tear off the fish meat bit by bit and put it into its mouth.
Seeing the giant Xiang Yang swimming towards it, the swimming crab was not afraid at all. Instead of abandoning the captured fish and running away, it waved its big claws at Xiang Yang in a domineering manner.
Some of the swimming crabs were attracted by Xiang Yang and actually changed their marching direction in an arc shape to encircle Xiang Yang.
Xiang Yang was stunned. Did the other party include himself in the recipe
In front of such a huge group, any individual power seems insignificant, except for terrifying creatures like whales and giant squids.
Xiang Yang did not allow the swimming crabs to surround him. He picked up the swimming crab in front of him that was as big as a ball, rushed out of the encirclement and quickly fled into the distance.
After breaking out of the encirclement, Xiang Yang swam at full speed towards the direction of Qinglong Bend without any hesitation.
There are so many swimming crabs. If you don’t catch them at this time, you would be reckless as a fisherman.
Xiang Yang swam back to Qinglongwan and climbed directly onto his father's small fishing boat. He threw the ball-sized swimming crab in his hand into the cabin. Without saying a word, he untied the reins that fixed the fishing boat and rowed the boat towards the south.
After the fishing boat reached a position where people on the shore could not see it, Xiang Yang repeated his old trick, jumped off the seabed, and dragged the entire fishing boat quickly towards the south.
Soon Xiang Yang caught up with the migrating school of fish and also saw the group of rampant swimming crabs.
"Mine, all mine." Xiang Yang quickly went back and forth between the sea surface and the seabed. Every time he went back and forth, he could catch a swimming crab weighing more than 150 grams, or a fresh lobster.
Swimming crabs were everywhere and were easier to catch than those in farms. In less than two hours, the cabin of Xiang's father's small fishing boat was filled with swimming crabs, and the waterline was approaching a very dangerous level.
Xiang Yang was still not satisfied. This kind of opportunity only comes twice a year. One is when the cold wave comes and the swimming crabs migrate south, and the other is when all things revive and the swimming crabs migrate north.
