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

    The plan for the year begins in spring. Raising fish and opening a fishery is the same as planting land and opening a farm. Spring is the golden time. It is at this time that many fish species are introduced into the fishery and started to be cultured.

    However, the fishery resources in Daqin Fishing Ground are already rich enough. There is no need to artificially stock fish fry. What needs to be done is to put in shellfish seedlings and cultivate shellfish.

    The fishery has some shellfish, 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 breeding. He does not need to buy shellfish from outside. The fishery started to breed some shellfish last year.  All have grown into strong oysters.

    The shellfish that is mostly cultured in fisheries is called Atlantic bay scallop. Its processing and utilization rate is very high, and almost its whole body is full of treasures.

    The adductor muscle of bay scallops can be processed into frozen fresh columns 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 be used as attachment stems for shellfish seedlings and are also an indispensable raw material for the shell carving industry. They are the first choice for scallop farming in countries along the Atlantic coast.

    Moreover, although bay scallops are warm-water species, their suitable temperature range is very wide, with the lower limit of temperature resistance being -1c and the upper limit being 34c.  It will stop growing below 5c, and can be cultured even in fisheries in the North Atlantic.

    The role of the Harvest began to show. In the morning, Qin Shiou took five veterans including Shaq and the Bulls, coupled with five newcomers Geng Junjie, and a group of more than ten people prepared to go to sea.

    On the beach, the sea monster and the remaining fishermen are also busy. Both parties have the same purpose, which is to catch the seashells cultured last year.

    There are two methods of fishing for shellfish, one is artificial fishing, and the other is mechanical fishing. Mechanical fishing is very simple. Just put the shell harvester into the seabed, let it work and collect the shellfish.

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

    In addition, there is a method of propeller trawling, because many scallops are hidden in the sand. The propellers are used to stir up the sand, and there are fishing nets around them. On the seabed, the shellfish float along with the sand, and finally fall into the sea.  In these fishing nets.

    What is interesting is artificial fishing, which has four methods. The sea monster is explaining it to the remaining five new fishermen.

    Qin Shiou originally wanted to get on the boat and go to sea, but the sea monster said that they didn't have enough people, so he stayed with two veteran fishermen to help collect shells manually.

    Artificial shell harvesting and mechanical shell harvesting both have specific applicable places. Beaches with no water after low tide are suitable for artificial shell harvesting, so sea monsters need so many manpower.

    Spring is the season when the sea water changes the most. After the tide recedes from the beach in the early morning, the wet seabed is exposed. Pieces of kelp, seaweed and water plants are exposed. Under the sunlight, it exudes a green luster and looks even better than on land.  There is spring color.

    Looking at the large tracts of underwater pasture, the sea monster sighed and said: "There are advantages and disadvantages. With the cover of these things, it will be much more laborious to collect oysters."

    Bay scallops are hermaphrodites, and they will complete the task of reproducing their own offspring, so all the scallops collected can be used as female scallops.  However, scallops are filter feeders and have 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, diflagellate algae, copepods, etc.; followed by algae spores, bacteria, etc.

    Because their own movement ability is not good, they will slowly move closer to an environment that has the same composition of food types as possible. In which environment do they have the most food?  That is in the underwater ranch.

    Therefore, most scallops are concentrated in or near seaweed and aquatic plants. In order to dig scallops, you have to go through the seaweed and aquatic plants, which increases the work burden.

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

    With seaweed and aquatic plants in this way, the feeling on the soles of people's feet will inevitably have errors. Some scallops are hidden deeper or are smaller, so you won't be able to detect them.

    It¡¯s okay for senior fishermen, they are very capable and experienced, and you can feel the presence of scallops after walking carefully.  The same cannot be said for the novices. They follow the veteran fishermen while retreating. Except for those that are particularly conspicuous, they are almost unnoticeable.

    However, the Bing brothers also worked hard. They took off their shoes and walked barefoot on the beach. This way, their senses were sharper and they would not miss the scallops easily.

    Qin ShiThe gull couldn't detect the scallop. After all, there was no water here and the Poseidon consciousness couldn't work. So he took off his shoes, and then he felt really damn cold, so he decisively put his shoes on again, so that he wouldn't suffer this fate.

    The sea monster laughed loudly and said: "After walking through this underwater pasture, there are no aquatic plants in front. We can use other methods to collect scallops. That will be simple."

    When they arrived at a place where there were no seaweeds or aquatic plants, Sea Monster and the others brought over the prepared iron planers and rakes. After inserting them into the beach to a depth of about 20 centimeters, they pulled the iron rake and tilted it back so that it would flip out when it hit the scallops.  .

    A group of fishermen shouted slogans and pulled long iron rakes, like plowing the ground. Scallops kept rolling out. Qin Shiou held a long clip in his hand, and he could pick up a scallop with a squeeze of the handle.

    This work is very tiring. After all, it is rare to have a strong man like Lu Zhishen who can pull up weeping willows upside down. The fishermen were sweating profusely after working for a while, and two groups of people came and worked alternately.

    To do this kind of work, you have to look at Ivoson. He can support four or five people by himself. Several groups of people changed, but he did not go down to rest. His pockets were filled with small cakes, cookies and other things, while dragging  While stuffing it into his mouth.

    Qin Shiou looked at it for a while and was stunned, then 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 holes somewhere on the beach. If the wheels of the ATV get stuck, it will be troublesome."

    The fishermen took turns pulling the plow at a very fast speed. Qin Shiou and his men quickly picked up piles of scallops.

    There are two conventional methods for collecting shellfish. One is to take advantage of their pile-seeking habits and drive a wooden pile at regular intervals in the cultivation area. After a certain period of time, these scallops will gather within about one meter around the wooden pile.  When the time comes, just collect them around the wooden piles.

    But this applies to general-scale and small-scale farming. If the scale is too large, there will be too many wooden stakes driven into the entire fishery, and it will be impossible to lower the net for fishing in the future.

    The fishing ground has never been piling, so this method is not useful.

    The last method is to fish for scallops, which is suitable for recreational and small-scale fishing.  (Remember the website address: www.hlnovel.com
