After getting engaged and sending off her parents and family, Winnie wholeheartedly prepares for the mayoral election of the town next month.

Qin Shiou can't give her much help in this regard, he has something to do, June is the time for the swordfish to return to the freshwater river to breed, and the Florida swordfish in the fishery ushered in the opportunity to expand the population.

However, the Buddha fish has strict requirements for the conditions of the spawning ground, first of all, the environment should be secluded, secondly, the water quality should be clear, the pollution should be light, and the water flow should be relatively fast, so as to ensure the abundance of bait, and finally the river bottom should be gravelly, and they are used to hiding their eggs underneath.

Fortunately, the small river flowing down from Mount Kanbal met this condition, so Qin Shiou would save trouble.

Qin Daguan was very worried that something would go wrong with them, so he monitored their reflux throughout the whole process, you must know that there are salmon in the mountains and rivers, these things are meat-eating, and if you catch a weak swordfish, it must be a nonsense meal.

Thousands of swordfish may sound like a lot, but in fact they are nothing to the oceans and rivers, especially since these fish are so small that a small mountain river is enough for them to spawn.

At night, Qin Shiou's four sea gods consciousness are all dispatched, and the knife fish, like other species, are restless when they are about to spawn, they have been looking for fresh water inlets these days, if Qin Shiou doesn't do it again, they will go north to find the big river.

According to research, it has been found that there are iron particles in the brains of swordfish, which can act like a compass to help them determine their direction in the vast ocean.

And they have strong sensory abilities, and they can sense the difference in the content of salt particles when they are 100 meters away from the sea. With these two abilities, they can find rivers by the sea in unfamiliar waters.

The reason why it must be reflowed. Scientists still haven't fully figured out why, and at first some thought that their eggs were the same as salmon. It can only survive in fresh water, but later studies found that this is not the case.

Qin Shiou believes that the reason why swordfish return to spawn is that the safety in the river is higher than that in the ocean.

Although their eggs are not as large and delicious as salmon eggs, they are very dangerous in the ocean because they are still for a long time when they spawn.

Finding the school of swordsfish in a hurry, Qin Shiou used the Seagod Consciousness to envelop and control them, and then brought them to the location of the estuary of the river together.

At this time, Qin Shiou couldn't be anxious. He'll have to wait a while to give the swordfish an acclimatization.

For marine fish, sudden exposure to fresh water is a matter of life and death, as their kidneys and other organs have to adapt to a sudden lack of salt.

For example, salmon, once they enter the river, they will stop eating, or even stop drinking, and they rely on the energy stored in the whole freshwater to survive. Therefore, once the salmon have spawned, it is not delicious, and the fat in their body is almost exhausted. The taste is naturally not beautiful.

Swordfish are too small to store much fat, and they don't have enough energy to survive the spawning process, so they need to adapt. Adapt to changes in the environment.

Just like humans, children from lower social backgrounds tend to be more socially adaptable, and the same is true for marine life.

In the normal process. The swordfish has to live for a week to ten days at the mouth of the sea, and the Poseidon energy changes this process. Qin Shiou helped them input Seagod energy, which only lasted for more than an hour. The fish automatically swim up the freshwater.

At this point, they are ready to adapt to freshwater environments.

But at most they swim to the waterhole at the top of the grove, and beyond that there is a small waterfall, the swordfish are too delicate to climb over such a waterfall, they are not salmon, and they can even jump over a waterfall ten or twenty meters high!

Being able to enter waterholes and rivers is satisfied, the swordfish are satisfied, they swim carefully at the bottom of the river, and they will quickly flee when the wind blows, which is a habit they have developed in the ocean.

Swordfish are so low-level that as long as they can eat meat, they can almost be bullied.

Atlantic salmon can be found in rivers and waterholes, and generally Pacific salmon migrate to spawn and die, while Atlantic salmon can migrate year after year to spawn, and some can even survive in rivers for a long time.

Qin Shiou used the sea god consciousness to search and drive these Atlantic salmon to the fishing grounds.

In this regard, the Atlantic salmon said that Qin Daguan had gone too far, this is a dove occupying the magpie's nest, right? This is a stepmother beating a child, right? As a result, the angry salmon began to express their emotions and began to devour the capelin when they entered the estuary.

There is not so much food in the river, and the Atlantic salmon are hungry most of the time in the river, so they have the opportunity to eat, how can they give up?

The capelin felt very hurt, and they wanted to ask these domineering salmon, why are you so cruel to me?

The big salmon attracts the predation of other fish, the first of which is the bluefin tuna, a school of dozens of large fish roaring and eating the salmon in the sea like a plough.

The capelin is very grateful to the bluefin tuna for their righteous action, they eat pot pulp to wait for the king, but the king is still hungry after killing the salmon, and turns back to the fellows, and the food is still very hilarious.

Upon entering the river, the stupid-looking swordfish show the wisdom of the race, they are not randomly distributed, but the fatter the female, the safer the position, and the male waits at the mouth of the river.

They stop there, not to fight the big fish that come to them, but to feed the belly of the big fish at the expense of themselves when they encounter the big predators, so that the big fish can spare the females who are giving birth.

This is a great spirit, but unfortunately they taste very good, and the population is usually relatively small, and the big fish will eat the marrow after eating them, and by the way, the female fish will eat them together......

There is no such danger in the fishing grounds, Qin Shiou arranged for two sea pythons to stay at the mouth of the sea, as long as there are big fish approaching, then drive them away.

Two sea pythons are equivalent to two gate gods, and with them, the swordfish can safely spawn.

In order to prevent accidents, Qin Shiou even took away the spotted turtle, this rare turtle likes to eat fish eggs, but it doesn't matter if the leatherback turtle is fine, they only like to eat jellyfish, fish eggs and the like are not their dishes.

Since Qin Shiou took charge of the fishing grounds, in the past two and a half years, the creatures in the fishing grounds have been protected, and the number of spotted water turtles has increased significantly, from only a few dozen when they first arrived, and now it has expanded to a scale of several hundred.

The number of this kind of turtle is not easy to calculate, because the size is too small, some will find a hole to hide, and one hiding is a month, and it is impossible to check it...... (To be continued......)
