1534. Spring shellfish

The soldiers are here to transform the drones, and Qin Shiou is ready to work with the fishermen.

The plan of the year lies in the spring, fish farming and opening a fishery is the same as farming and opening a farm, spring is the golden season, and many fish species are sown into the fishery at this time to start breeding.

However, the fishery resources of Daqin Fishery are rich enough, and there is no need to artificially stocking fish fry, what needs to be done is to put in shellfish fry and breed shellfish.

There are some shellfish in the fishery, including scallops and so on, but the number is not enough, the output can not keep up with the market demand, Qin Shiou must expand the scale of breeding, he does not need to buy shellfish seedlings from outside, the fishery began to breed some shellfish last year, all of which have grown into strong female oysters.

The shellfish that is cultivated in the fishery is called the Atlantic Bay scallop, which has a high processing utilization rate and is almost all treasured.

The adductor muscle of bay scallops can be processed into frozen fresh columns and canned food, and the mantle can be processed into shellfish, which can be eaten or used as fresh bait for fish and shrimp. The two shells can be used as the attached stems of shellfish seedlings, and are also indispensable raw materials for the shell carving industry, and are the first choice for scallop cultivation in countries along the Atlantic coast.

In addition, although the bay scallop is a warm-water species, it has a wide range of suitable temperatures, with a lower limit of -1 °C and an upper limit of 34 °C. It does not stop growing until below 5°C, and can be farmed even in North Atlantic fisheries.

The role of the harvest began to show, and in the morning, Qin Shiou brought five veterans such as Shaq and Bull, and five newcomers from Geng Junjie, and a group of more than ten people prepared to go to sea.

On the beach, the sea monster and the rest of the fishermen are also busy, with the same purpose, which is to catch the sea shells farmed last year.

There are two means of shellfish fishing, one is manual fishing, and the other is mechanical fishing, which is very simple. Put the shellfish harvester on the bottom of the sea, let it work and collect the shellfish.

The shellfish harvester used in Daqin Fishery is the SP-12 shellfish harvester produced by Siemens Fisheries, which is very suitable for harvesting scallops in the Atlantic Bay, and can harvest 500-800 kg per hour with a damage rate of no more than 3-5%.

There is also the propeller trawl method, because many scallops are hidden in the mud and sand. Propellers are used to stir up the sediment, surrounded by fishing nets, where shellfish float along with the sediment and end up in these nets.

What's interesting is that there are four methods of manual fishing, and the sea monster is explaining to the remaining five soldiers, brothers, and rookie fishermen.

Qin Shiou originally wanted to get on the boat and go to sea, but the sea monster said that there were not enough of them, so he stayed with the two fisherman veterans. Let's help with manual shell picking.

Both manual and mechanical shellfish harvesting have specific applicable places, and beaches without water after low tide are suitable for manual shell harvesting, so the sea monster needs so many manpower.

Spring is the season when the sea water changes the most drastically, and when the tide recedes from the beach in the early morning, the wet seabed is revealed, and patches of kelp, seaweed, and aquatic plants are revealed, which glow green in the sun. It looks more spring than on land.

Looking at the vast area of undersea pastures, the sea monster sighed. Said: "There are really advantages and disadvantages, with the cover of these things, it is much more difficult to collect the mother oyster." ”

Bay scallops are hermaphroditic and do the task of reproducing their offspring, so all scallops collected can be used as female oysters. However, scallops are filter feeders. It has the ability to choose the size of the food, but not the type of food.

Their main diet is organic detritus, microscopic particles suspended in seawater, and plankton, such as diatoms, diflagellated algae, copepods, etc.; Secondly, there are spores of algae, bacteria, etc.

Because they are not able to move well, they move slowly to the environment that is as consistent as possible with the composition of the food type, and where do they eat the most? That's in the undersea ranch.

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

In addition, the first and simplest of the four types of scallops harvested by hand is to constantly step on the beach with both feet, and use the feeling of the soles of the feet to find the scallops and dig them out.

In this way, with seaweed and aquatic plants, it is inevitable that there will be errors in the soles of people's feet, and some scallops that are hidden deep or relatively small will not be noticed.

The senior fisherman is okay, with strong skills and experience, and he can feel the presence of scallops after walking carefully. Novices are not good, they follow the old fishermen as they step and retreat, except for the particularly conspicuous ones, which are almost imperceptible.

However, the soldiers are also quite hard, and they have taken off their shoes and walked barefoot on the beach, so that the feeling is more keen, so that it is not easy to miss the scallops.

Qin Shiou couldn't notice the scallops, after all, there was no water here, and the Poseidon consciousness couldn't play a role, so he took off his shoes and then felt really cold, so he decisively put on his shoes again, so that he didn't suffer from this crime.

The sea monster laughed and said, "Walking through this underwater pasture, there are no more aquatic plants in front of us, and we can use other methods to collect scallops, so it will be easy." ”

When they arrived at a place where there were no seaweeds and aquatic plants, the sea monster and others brought over the prepared iron planers and iron rakes, inserted them into the beach to a depth of about 20 centimeters, and pulled the iron rake to tilt and retreat, so that after hitting the scallops, they would turn out.

A group of fishermen shouted the trumpet and dragged a long iron rake, like ploughing the ground, and there were scallops rolling out continuously, Qin Shiou held a long clip in his hand, and he could pick up a scallop with a pinch of the handle.

This work is very tiring, after all, it is still rare to be able to uproot the weeping willows like Lu Zhishen, and the fishermen sweat profusely after a while, and two groups of people come to do it in turn.

It's up to Iverson to do this kind of work, he can handle four or five people alone, and he has changed several groups, and he doesn't go down to rest, his pocket is full of small cakes, cookies, and other things, and he drags and stuffs them into his mouth.

Qin Shiou was stunned 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's not good, the power of the ATV is uneven, and there may be mud puddles somewhere on this beach, and the wheels of the ATV will be in trouble if they sink in." ”

The fishermen took turns pulling the plows, and the speed was also very fast, and Qin Shiou led people to quickly mobile a pile of scallops.

There are two conventional ways to collect shellfish, one is to take advantage of their pile-grabbing habits, where they are stumped at intervals in the growing area, and after a certain period of time, these scallops will be concentrated within a meter or so around the stake, and then they can be collected around the stake.

But this applies to both general and small-scale farming, where the scale is too large, and the whole fishery has to drive too many stakes, and it is impossible to catch the net in the future.

The fishery has not been piled, so this method is not used.

The last option is scallop fishing, which is suitable for recreational and small batch fishing. (To be continued......)
