Golden Fishery

The soldiers are transforming the drones here, and Qin Shiou and the fishermen are ready to work.

The plan of the year lies in spring. Fish farming and fish farms are the same as farming and farms. Spring is the golden season, and many fish species are broadcast into fish farms at this time to start breeding.

However, the fishery resources in the Daqin Fishing Farm are already abundant enough, so there is no need to artificially stock the fish fry, what needs to be done is to put in the shellfish seedlings and raise the shellfish.

There are some shellfish in the fishery, including scallops, etc., but the quantity is not enough, and the output cannot keep up with the market demand. Qin Shiou must expand the scale of farming. He does not need to buy shellfish seedlings from outside. The fishery started to raise some shellfish last year. They have all grown into strong oysters.

The most common shellfish in fish farms is called Atlantic Gulf scallop. Its processing and utilization rate is very high, and almost its whole body is full of treasures.

The adductor muscle of the bay scallop can be processed into frozen fresh pillars and cans, and the mantle can be processed into shell edges, which can be eaten or used as fresh bait for fish and shrimp. The two shells can not only be used as attachment stems for shellfish seedlings, but also indispensable raw materials for the shell carving industry, and are the first choice for cultivating scallops in countries along the Atlantic coast.

Moreover, although bay scallops are warm-water species, they have a wide temperature range, with the lower limit of temperature resistance being - and the upper limit being -. The following will stop growing, even the fishing grounds in the North Atlantic Ocean can be cultured.

The role of the Harvest began to show. In the morning, Qin Shiou brought five veterans including Shaq and Bull, and five newcomers Geng Junjie. A group of more than ten people was ready to go to sea.

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

There are two methods of shellfish fishing, one is manual fishing, and the other is mechanical fishing. Mechanical fishing is very simple. Just drop the shellfisher into the ocean floor, let it work and collect shellfish.

The shellfish harvesting machine used by Daqin Fishery is the sp-12 shellfish harvesting machine produced by Siemens Fisheries Company. It is very suitable for catching scallops in the Atlantic Gulf. It can harvest 500-800 kg per hour, and the damage rate does not exceed 3-5%.

There is also the method of propeller trawling, because many scallops are hidden in the sand. The mud and sand are stirred up with a propeller, and there are fishing nets around them. At the bottom of the sea, shellfish float together with the mud and sand, and eventually fall into these fishing nets.

What's interesting is manual fishing, which has four methods, and the sea monster is explaining it to the remaining five newcomer fishermen.

Qin Shiou originally wanted to get on the boat and go to sea, but the sea monster said that they were not enough, so he stayed with two veteran fishermen. Let's help shellfish picking together.

Both artificial and mechanical shell picking have specific applicable places.

Beaches without water after low tide are suitable for manual shellfishing, which is why sea monsters need so many people.

Spring is the season with the most dramatic changes in sea water. In the early morning, after the tide recedes from the beach, the green seabed is exposed, and patches of kelp, seaweed and aquatic plants are exposed, exuding a green luster under the sunshine. It looks more spring than on land.

Looking at the large seabed pastures, the sea monster sighed. Said: "There are advantages and disadvantages. With the cover of these things, it will be much more difficult to collect mother oysters."

Bay scallops are hermaphroditic, and they will complete the task of reproduction by themselves, so all scallops collected can be used as female shells. However, scallops are filter feeders. It has the ability to select the size of food, but not the type.

Their main food is organic debris, micro-particles suspended in seawater and plankton, such as diatoms, dinoflagellates, copepods, etc.; followed by algae spores, bacteria, etc.

Because their own movement ability is not good, so they will slowly move close to the environment that is as consistent as possible with the composition of food types, and in which environment do they have the most food? That is in the sea ranch.

so. Most of the scallops are concentrated in or near the seaweeds, so to dig scallops you have to go through the seaweeds and the like, which increases the workload.

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

In this way, with seaweed and aquatic plants, it is inevitable that there will be errors in the feeling of the soles of the feet. Some scallops that are hidden deeper or smaller will not be noticed.

The senior fisherman is okay, with strong skills and experience, and he can feel the existence of scallops after walking carefully. Novices can't do it, they follow the old fishermen stepping and retreating, except for the ones that are particularly conspicuous, they are almost unnoticeable.

However, the soldiers also worked hard. They took off their shoes and walked barefoot on the beach one after another. This made them feel more sensitive, and it was not easy to miss the scallops.

Qin Shiou couldn't notice the scallops either. After all, there was no water here, and the sea god's consciousness couldn't work, so he took off his shoes, and then felt so fucking cold, so he put on his shoes decisively, so he wouldn't suffer.

The sea monster laughed loudly and said, "Walking through this seabed pasture, there are no aquatic plants in front. We can use other methods to collect scallops, and that will be easy."

When they arrived at a place without seaweed and water plants, the sea monster and others brought the prepared iron planer and iron rake, inserted them into the beach to a depth of about 20 centimeters, and then pulled the iron rake backwards according to the slope, so that they would turn out after hitting the scallops. .

A group of fishermen shouted and dragged the long iron rake, like plowing the field, and scallops kept rolling out. Qin Shiou was holding a long clip in his hand, and he could pick up a scallop with just a pinch of the handle.

This work is very tiring. After all, it is still rare to see a fierce man who can pull weeping willows upside down like Lu Zhishen. The fishermen were sweating profusely after working for a while, and two groups of people came and switched to do it.

It is up to Iverson to do this kind of work. He can support four or five people by himself. He has changed several groups of people. Stuff it in your mouth.

Qin Shiou was stunned after watching for a while, and asked, "What do you think if we use an ATV to pull the plow?"

The sea monster shook his head and said, "That won't work. The power of the ATV is uneven, and there may be mud puddles somewhere on the beach. It will be troublesome if the ATV's wheels sink."

The fishermen took turns pulling the plow, and the speed was really fast. Qin Shiou led his men to quickly collect piles of scallops.

There are two other conventional methods for collecting shellfish. One is to make use of their pile-tending habit and place wooden piles at intervals in the grow-out area. After a certain period of time, these scallops will gather within about one meter around the wooden piles. Inside, just collect around the stakes when the time comes.

But this is applicable to general-scale and small-scale farming. If the scale is too large, too many stakes will have to be driven into the entire fishery, and the fish will not be able to catch the nets in the future.

The fishing ground has never been piled, so this method cannot be used.

The last method is to fish for scallops, which is suitable for recreational and small batch fishing. (To be continued..)u
