Golden Fishery

After a busy day, together with sea fishing and manual picking, the collection of scallops is almost done. There are pools of scallops left on the beach. As long as there is enough water vapor, they will not be life-threatening. They live well here . △↗,

Qin Shiou came over chewing gum, watched the sunset and these mother shells, and planned tomorrow's work.

The rays of the setting sun are falling gently, the weather in early spring is still a bit chilly, the evening wind blows on people's faces is still a little cold, tigers, leopards, bears and wolves are chasing each other on the beach.

Xiong Luoli stared at the scallops curiously, and then took advantage of no one's attention, walked up to smash a few scallops carefully, opened its mouth to reveal its pink and tender tongue, and licked it into its mouth.

The umami taste of the scallops quickly conquered its taste buds, Xiong Luoli was very happy, opened his fat paws and patted the scallops, licked the shells and swallowed them together.

Noticing this, the silent Iverson rushed up immediately, picked up Loli Xiong and dragged it back.

Xiong Luoli howled unwillingly, and Xiong Da roared when he heard it, showing the majesty of the king of the forest. Unfortunately, when he turned his head and saw Iverson hugging Xiong Luoli, he was immediately depressed, and sat there in a daze .

Obviously, Iverson left such a deep impression on Xiong Da in his youth that he still has lingering fears now.

The seals are also eyeing the scallops. Because they have no claws and only limbs similar to fish fins, they cannot dig shellfish in the sand by themselves. Of course, there were short-tailed fulmars and herring gulls in the previous fishing grounds, and the seals also Forget about eating scallops.

Now that the fulmars are gone and the herring gulls have been driven away, the seals are left with alternatives to food.

There is no doubt that things like capelin and herring mackerel taste better for them, but catching fish requires action. The scallops piled up here. In this way, scallops seem to be a good food for seals who can be as lazy as possible, and can beep as little as possible.

Qin Shiou saw that this was not going to work, a group of guys were staring at the scallops, other things to say, scallops have hundreds of thousands of mother bodies, so it's nothing to eat. But the seals are also eyeing them, and that's a problem. The seals are not only numerous, but each of them is a big eater!

Therefore, he could only direct the fishermen to eat a little tired all night, and send these shells around the engineered breeding pool.

The next day will be the frying of bay scallops.

Seed production of bay scallops is one of the leading shellfish industries on the Atlantic coast, and nursery techniques have improved considerably over the years, but there are still many fisheries that do not get enough scallop larvae each year because hatch rates are too low .

Thereby directly lead to the failure of raising seedlings.

Therefore, improving the hatching rate of bay scallops is one of the key technologies for seedling production. Qin Shiou not only needs to input Poseidon energy into them, but also try to adopt more scientific breeding methods, and cannot rely solely on Poseidon energy.

All the fishermen went to battle, and Shaq, Sea Monster, Bull, and Smoker each led a team of ten people to select the female shells separately and put them on different breeding rafts according to the quality of the female shells.

The last mother shell. It is the kind of bay scallop with full gonads, large individual and complete appearance. It is sorted and selected and put into different breeding ponds. Adjust the water temperature and the oxygen content in the water, and carry out the temporary maintenance and ripening of the mother shellfish.

The cultivation of female oysters is the basis. They are hermaphroditic, and their reproductive habits are in vitro fertilization and in vitro development. Generally, they lay eggs and reproduce in spring and autumn, which is obvious. The degree of maturity of gonad development of female oyster directly affects the quality of eggs retrieved.

In fact, Daqin Fishing Farm is not the most suitable place to raise seashells. Take this kind of scallops as an example. They can be harvested twice a year in the South Atlantic Ocean, including the Gulf of Mexico, but here they can only be raised for one season.

Of course, there are gains and losses. Compared with scallops in the southern tropical waters, the bay scallops produced in the North Atlantic Ocean, especially Newfoundland fishing grounds, are of better quality, less polluted, and can be sold at a higher price.

Because it has entered the seedling breeding season of various marine products, Saunders came back from the No. 2 fishing ground to give guidance. He took Qin Shiou to watch the scallops on the breeding raft one by one.

After reading it, the old professor was a little depressed, and said, "Darling from the fishing ground, the quality is pretty good."

Qin Bei means female mother. Qin Shiou thinks the latter name is more appropriate, but Sanders is an academic after all, and his words are more precise. After hearing this, he feels that he will also be called Qin Bei in the future, which is more appropriate.

As for the depression of the old professor, he can understand it very well. In fact, although the old man is a genius, he is not very effective in the fishing ground. He finally had a black-covered giant worm project, but Qin Shiou stopped it because of lack of raw materials. Unfortunately.

Hearing what the old professor said, Qin Shiou grinned and said, "These scallops are all high-quality scallops I imported from other fishing grounds. Of course, the quality is better, and I don't want them if they are not good."

Now there are two main types of scallops commonly used in major fishing grounds in Canada, the American Gulf scallop and the Mexican Gulf scallop. Both scallops have their own advantages and disadvantages, but they all have a common problem, which is the decline in quality.

The reasons for this are, firstly, the degradation of the germplasm of the shellfish; secondly, the pollution of the breeding environment; thirdly, problems such as operation management and breeding density; and fourthly, breeding problems.

Two types of bay scallops have been cultured in North America for more than half a century. The Mexico bay scallop was introduced from Mexico. Because the country in Laomo was unstable at the time, the number of introduced species in the two countries was limited, and it, a nightmare, breeds one generation every six months. , so after more than half a century of artificial breeding, it is inevitable that there will be inbreeding.

Just like human beings, the quality of children born from inbreeding marriages cannot be guaranteed, and the breeding traits of shellfish will degrade over time. Sanders initially thought the fish farm would encounter this problem, and he wanted to solve it to show his strength.

As a result, the strong female oysters did not give him a chance!

After looking at the quality of scallops, Saunders suggested that Qin Shiou could not engage in primitive farming, but start a seedling cultivation business, which is more profitable than primitive farming, because it makes money quickly, and does not need to raise fish, shrimp, and scallops. It takes years or even years to produce.

The Canadian scallop industry is currently facing a crisis of quality decline. There are two ways to solve this crisis. One is to re-introduce the original species of Gulf of Mexico scallops from the United States and Mexico and carry out breeding, which costs more.

Another way is to select high-quality shellfish to breed and breed by yourself. This is cheap, but it is not easy to operate and the cycle is long. It is like manual selection of high-quality species. It takes several rounds of selection and mating, and the results can be obtained after repeated comparisons.

Qin Shiou thought about it, this is also a good idea for development, transforming the mother body with the sea god consciousness, so that the fish fry, shrimp fry, and shellfish produced in this way will be of high quality, and it can be regarded as using the golden finger to the greatest extent to contribute to marine life.
