Chapter 1559

The soldiers are here to transform the UAV. Qin Shiou and the fishermen are ready to work.

A year's plan is spring. Fish farming and fishing grounds are the same as farming farms. Spring is the golden season. Many fish species are sown to fishing grounds to start breeding.

However, the fishery resources of Daqin fishing ground are rich enough. There is no need to raise fish fry manually. What we need to do is to put in shellfish fry and cultivate shellfish.

There are some shellfish in the fishing ground, including scallops, but the quantity is not enough, and the output can not keep up with the market demand. Qin Shiou must expand the breeding scale. He does not need to buy shellfish seedlings from outside. The fishing ground began to breed some shellfish last year, which have grown into strong mother shellfish.

The shellfish cultured in the fishery is called Atlantic bay scallop. Its processing and utilization rate is very high, and almost all of its body is treasure.

The adductor muscle of bay scallop can be processed into frozen fresh columns and cans, and the outer membrane can be processed into scallop edges, which can be eaten or used as fresh bait for fish and shrimp. The two shells can not only be used as the attachment stem for shellfish seedling raising, but also an indispensable raw material for shellfish carving industry. They are the first choice for cultivating scallops in countries along the Atlantic coast.

Moreover, although bay scallop belongs to warm water species, it has a wide temperature range. The lower limit of temperature tolerance is - 1 ℃ and the upper limit is 34 ℃. The growth will not stop until it is below 5 ℃. Even the fishing grounds in the North Atlantic can be cultured.

The role of Fengshou began to show. In the morning, Qin Shiou took five veterans such as shack and bull, together with five newcomers such as Geng Junjie, and a group of more than ten people ready to go to sea.

On the beach, the sea monster and the remaining fishermen are also busy. The purpose of both sides is the same, that is to catch the seashells cultured last year.

There are two ways to catch shellfish, one is artificial fishing, the other is mechanical fishing. Mechanical fishing is very simple. Put the shellfish picking machine into the seabed, let it work, and then collect shellfish.

The shellfish harvester used in Daqin fishing ground is sp-12 shellfish harvester produced by Siemens fishery company. It is very suitable for catching Atlantic bay scallops. It can harvest 500-800 kg per hour, and the damage rate is no more than 3-5%.

In addition, there is the propeller trawl operation, because many scallops are hidden in the sediment. They mix the sediment with the propeller. There are fishing nets around. On the seabed, shellfish float with the sediment and finally fall into these fishing nets.

Interestingly, there are four methods of artificial fishing. The sea monster is explaining it to the remaining five soldiers, brothers and new fishermen.

Qin Shiou wanted to go to sea, but the sea monster said they were not enough, so he stayed with two fishermen and helped collect shellfish manually.

Artificial shellfish and mechanical shellfish are suitable for specific places. Beaches without water after ebb tide are suitable for artificial shellfish, so sea monsters need so many people.

Spring is the season with the most drastic changes in sea water. After the tide retreats from the beach in the morning, the wet seabed is exposed, and patches of kelp seaweed and aquatic plants are exposed. Under the sunshine, they emit a green luster, which looks more spring than on land.

Looking at the vast undersea pasture, the sea monster sighed and said, "it's really good and bad. With the cover of these things, it's much more difficult to collect mother shells."

Bay scallops are hermaphroditic. They will complete the task of reproduction by themselves, so all the scallops collected can be used as female scallops. However, scallops are filter feeders. They have the ability to choose the size of food, but they have no ability to choose the species.

Their main food is organic debris, micro particles suspended in seawater and plankton, such as diatoms, dinoflagellates, copepods, etc; Secondly, there are algae spores, bacteria and so on.

Because of their poor exercise ability, they will move slowly close to the environment as consistent as possible with the composition of food types, and where do they have the most food? That's the undersea ranch.

Therefore, most scallops are concentrated in or near seaweed plants, so to dig scallops, they have to go through seaweed plants, which increases the workload.

In addition, among the four kinds of manually collected scallops, the first and simplest one is to step on the beach with both feet, use the feeling of the soles of your feet to find the scallops and dig them out.

In this way, with seaweed and water plants, it is inevitable that there are errors in the feeling of people's soles. Some scallops hidden deep or small can't be detected.

The senior fisherman is OK. He has strong skills and sufficient experience. He can feel the existence of scallops after walking carefully. Novices can't do it. They step back with the old fishermen. They can hardly notice it except the one that is particularly conspicuous.

However, the soldiers also worked hard. They took off their shoes and walked barefoot on the beach one after another. In this way, they felt more sensitive and were not easy to miss scallops.

Qin Shiou couldn't notice the scallops. After all, there was no water here, and the Sea God consciousness couldn't play a role, so he took off his shoes, and then felt really fucking cold. He put on his shoes decisively, so he wouldn't suffer this crime.

The sea monster laughed and said, "after walking through this undersea pasture, there is no water and grass in front. We can use other methods to collect scallops. That's simple."

When there are no seaweed and water plants, the sea monster and others bring the prepared iron planer and iron rake to the beach, insert them into the beach at a depth of about 20 cm, pull the iron rake to tilt back, so that they will turn out when they hit the scallop.

A group of fishermen shouted and dragged the long iron rake like ploughing. Scallops rolled out constantly. Qin Shiou held a long clip in his hand and could pick up a scallop as soon as he squeezed the handle.

This work is very tiring. After all, it is rare for fierce people like Lu Zhishen to pull down the willows. The fishermen sweat profusely after working for a while, and two groups of people change jobs.

It was up to Iverson to do this kind of work. He could support four or five people alone. He changed several groups of people. He didn't go down to rest. His pocket was full of small cakes, cookies and other things. He dragged and stuffed them into his mouth.

Qin Shiou was stunned and asked, "what do you think if we use a beach car to pull the plow?"

The sea monster shook his head and said, "that's no good. The power of the beach car is uneven, and there are mud pits anywhere on the beach. If the wheels of the beach car sink, it's troublesome."

Scallop in shell, the fishermen took turns to pull plows, and the speed was fast. Qin Shi Kwai brought people a lot of scallops.

There are two conventional methods to collect shellfish. One is to use their pile tendency habit to drive a wooden pile at intervals in the cultivation area. After a certain period of time, these scallops will be concentrated within about one meter around the wooden pile, and then they will be collected around the wooden pile.

However, this is applicable to general scale and small-scale aquaculture. If the scale is too large, there are too many wooden piles to be driven into the whole fishery, and it will be impossible to get off the net in the future.

The fishing ground has not been piled, so this method can't be used.

The last way is to catch scallops, which is suitable for entertainment and small batch fishing.
