Chapter 633

In general, when attacked by COD, salmon and various tuna, hairy scale fish will swarm into shallow rivers. In fact, most marine fish are very sensitive to salt, and they will not be close to the estuary of the river.

Therefore, it is safer to stay at the entrance to the sea.

But it's useless for sharp billed fish. This kind of fish also likes to live at the mouth of the river and is the natural enemy of hairy scale fish.

Under normal circumstances, a large number of hairy scale fish will not stay at the mouth of the sea. There is not enough living space, food is not enough and unsafe. They will enter the deep sea when they are almost mature.

These hairy scale fish in Daqin fishing ground have been transformed by Poseidon energy and attracted by the food in the fishing ground, which makes them stay in the fishing ground and become a poor existence at the bottom of the food chain.

Although Qin Shiou wanted to use this kind of fish to replace herring and mackerel to feed the big fish in the sea, it didn't mean that he allowed any fish to eat them. In other words, the monk, the nun in the temple, couldn't touch ah Q.

When the sharp billed fish found the hairy scale fish in the estuary, they were very excited. They plunged into the waters of the estuary like torpedoes. Their mouths opened and wreaked havoc in the water. They not only ate, but also killed the hairy scale fish for fun.

Qin Shiou suddenly became angry. These hairy scale fish are the key objects of his cultivation. They input more Poseidon energy than tuna, so that they can grow, mature, spawn and expand the strength of the hairy scale fish group as soon as possible.

As a result, it's cheap now!

After discovering this problem, he jumped up from the recliner, drove the motorboat out for a circle, pretended to patrol the fishing ground, and then came back and shouted to the smokegun who had just got off the ship: "take the purse seine, the fishing ground has been invaded!"

When they heard Qin Shiou's cry, they thought someone had come to the door and hurriedly prepared for the harvest.

The bull took off his coat, showed his black hair on his chest and roared, "Captain, wait a minute, I'll take the Remington my father left me! I must smash the heads of those Biao sons! "

The cigarette gun frowned and said, "what's the use of holding a gun? I also believed in his God. Haven't the missiles in the fishing ground been displayed? This time we'll shoot them with missiles! "

Zach said weakly, "am I the only one who found the problem? The captain said let's take the purse seine. It's obvious that sharks invaded the fishing ground?"

Everyone looked at Qin Shiou. Qin Shiou asked the sky in silence: did he advocate violence a little too much before? As a result, these honest fishermen have been influenced and become more violent than themselves!

"Sharp billed fish, it's a group of sharp billed fish!" Qin Shiou said weakly, "don't use guns and missiles. Take a purse seine and fish them up and sell them."

The fish meat of sharp billed fish is very delicate, white and tender, and there are few finely broken bones. Small fish can be fried dry, while large fish are suitable for steamed, which tastes very good.

The bull takes people to clean up the purse seine. The link on the harvest is a trawl. Qin Shiou usually doesn't use the purse seine.

In Qin Shiou's opinion, this kind of net is a little too fierce. It is specially used to round up clustered fish. During operation, the fish are surrounded by nets, forcing them to concentrate on the net bag and catch them all, regardless of size!

This is different from the trawl. The trawl always drags the fish. In fact, the fish have activity space. As long as the mesh of the trawl is large enough, the small fish will get out of the mesh, and the big fish can get out from both sides as long as they escape quickly.

What about the purse seine? That's a dragnet, although nominally, the fishing efficiency of the purse seine depends on the technical level of fish exploration and fishing. However, due to the use of high-tech sonar fish detector and the strengthening of fishing boat purse seine automation, there is little empty net.

As long as it is not an empty net, the fish in the selected sea area will continue to shrink towards the middle of the purse seine when frightened. Finally, the big fish and small fish crowd together, and no one can run away. They can't run around. The road is blocked and jump over the purse Seine from the water? That's impossible.

Qin Shiou refused to use the purse seine. He only caught the big fish with the trawl, and the small fish would be let go. However, Purse Seine is now the main fishing gear for countries to catch pelagic fish resources. The annual catch of Marine Fisheries accounts for about 30% of the total marine catch.

Moreover, with the improvement of fishing technology and the popularization of modern fish exploration equipment, the scope of purse seine fishing objects is expanding, and it has been able to capture clustered fish near the bottom.

This is a disaster for marine fish!

The bull and several fishermen quickly hung the sorted purse seine on the Fengshou, and set sail with a pipe in its mouth. Fengshou quickly turned around and drove towards the estuary of the river in the northeast.

Close to the waters over there, the fish detector began to make a cry of "didi didi", which means to find a school of fish.

When the fishing boat reached the top of the water, the motor began to work. The bull and Zach stood at the stern and threw the long belt-shaped fishing net into the water.

The purse seine on Fengshou is a structural form with low ends and high middle part. It is composed of the fish taking part in the middle of the net and two net wings. The upper outline, that is, the edge above the fishing net, is equipped with a plastic ball with strong buoyancy, which is enough to ensure that the upper outline of the net always floats on the water during operation, and the lower outline is equipped with a heavy plumb bob, which can facilitate the rapid settlement of the net and close the bottom of the net ring.

In addition, the upper and lower ends of the edge of the fishing net that the bull threw into the water at the beginning are also very different. The upper end is also a large rubber ball, and the lower end is hung with a plumb. In this way, after entering the water, one end of the fishing net will stand upright in the sea water.

Fengshou dragged the other end of the fishing net in an arc. After enclosing the waters with the most dense schools of sharp billed fish, the other edge of the purse seine was also thrown into the water. The same structure ensured that the other side of the fishing net was also erected in the ocean.

In this way, the machine retracts and twists the rope running through the lower part of the fishing net. First close the bottom of two circles, then retract and pull the net gear, narrow the net circle and start the finishing work.

The sharp billed fish were frightened and ran away from all around to the middle. As a result, the big fish easily knocked out when they collided with each other. In this way, the small fish were more frightened. Finally, there was no way to escape and concentrated in the fish taking department in the middle of the Purse Seine.

The bull looked at the crowded sharp billed fish in the purse seine and said with emotion: "Captain, Fengshou is suitable for purse seine fishing. You see, its structure is flat bottom square tail, fast speed, flexible and good lateral stability. It's too wasteful to use it for trawl fishing."

Qin Shiou smiled and said, "it's better to trawl. Purse seine fishing once in a while. For example, this time, these damn sharp billed fish want to eat the small fish in the upper waters of our fishing ground. It's not good!"

After the purse seine was closed, the ship's motor started, and the closed funnel-shaped Purse Seine was pulled up with a roar.

The cigarette gun leaned out of the cab and whistled. "The fishing ground is really good. It's a good harvest, huh?"

The price of sharp billed fish is OK. This net looks like two or three meals. If it is sold, it can sell for forty or fifty thousand yuan.

There are also a large number of sharp billed fish in the sea. The harvest of Fengshou is not over. After this net, we have to go off the net and continue fishing. We can't leave too many sharp billed fish.
