Golden Fishery

After a day of busy work, together with sea catching and manual picking, the collection of scallops is finally almost done. A beach of scallops is left on the beach. As long as there is plenty of water vapor, they will not be in danger of life. They live well here. .

  Qin Shiou came over, chewing gum, watching the sunset and these mothers, planning his work tomorrow.

  The light of the setting sun is gently falling down, the weather in early spring is still a bit steep, the evening breeze is still a bit cold on people's faces, tigers, leopards, bears and wolves are chasing me on the beach.

  Xiong Lori stared at the scallops curiously, and then carefully walked up to smash a few scallops while no one was paying attention, opened her mouth to reveal her pink tongue and licked it into her mouth.

  The scallop's umami quickly conquered its taste buds. Xiong Lori was very happy. She opened her fat paws and slapped the scallops, licking the meat and swallowing the shells together.

  Noting this, the silent Ivorson galloped up immediately, picked up Loli Xiong and dragged it back.

Xiong Luoli was unwilling to howl, Xiong Da screamed after hearing the majesty of the king of the forest, but it was a pity that he turned his head to see that it was Ivorson holding Xiong Luoli, she was immediately depressed, and sat there in a daze. .

  Obviously, Ivorson impressed the boy Xiong Da so deeply that he still has lingering fears.

Seals also focused on scallops. Because they have no claws and only fin-like limbs, they cannot dig out shellfish in the sand by themselves. Of course, there were short-tailed hawks and silver gulls in the previous fishing grounds, and the seals also Don't care about eating scallops.

  Now that the short-tailed eagle has left, the silver gull has been driven away, and the seals have to choose food alternatives.

  There is no doubt. For them, capelin, herring, mackerel and the like taste better, but you have to do it to catch the fish, but scallops are piled up here. This is for seals who can be as lazy as possible, beep and try not to do it. Scallops seem to be good food too.

  Qin Shiou saw that this was not enough. A group of guys were staring at the scallops. For other things, scallops had more than 100,000 mothers. It's okay to eat, but the seals are also looking at them, which is troublesome. There are not only a large number of seals, but all of them are big stomach kings!

  So, he could only instruct the fishermen to get tired of eating overnight and send these shells around the engineering aquaculture pond.

  The next day will be the fry work of bay scallops.

  Bay scallop seed production is one of the leading shellfish industries in the Atlantic coastal area, which has undergone many years of improvement. The technology of raising seedlings has been greatly improved, but every year, many fisheries still cannot obtain enough scallop larvae because of the low hatching rate, which directly leads to the failure of seedling raising.

   Therefore, increasing the hatching rate of bay scallops is one of the key technologies for nursery production. Qin Shiou not only inputs Poseidon energy to them, but also uses more scientific breeding methods as much as possible, and cannot rely solely on Poseidon energy.

  The fishermen all go into battle. Shaq, sea monsters, bulls, and smoke guns each led a team of ten people to select mother shells separately and put them on different breeding rafts according to the quality of the mother shells.

  The last mother oyster is the bay scallop with full gonads, large individual, and complete appearance. After sorting and selecting, put it into different breeding ponds, adjust the water temperature and oxygen content in the water, and carry out the temporary breeding of the mother oysters.

  The cultivation of female oysters is the basis. They are hermaphrodite, and their reproductive habits are in vitro fertilization and in vitro development, usually spawning and breeding in spring and autumn. This is obvious. The maturity of female gonads directly affects the quality of eggs.

  In fact, the Daqin fishery is not the most suitable place for cultivating sea shells. Take this scallop as an example. They can be harvested twice a year in the South Atlantic Ocean, including the Gulf of Mexico. Here you can only raise one season.

  Of course, there must be gains, compared with the scallops in the southern tropical waters. The bay scallops produced in the North Atlantic, especially in Newfoundland, are of better quality, lower pollution, and can be sold at higher prices.

  Because of entering the breeding season of various kinds of marine fish seedlings, Sanders came back from the No. 2 fishery specially for 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, "The relatives of the fishing grounds, the quality is good."

  Qinbei means mother. Qin Shiou thinks the latter term is more appropriate, but Sanders is an academic, and uses more precise words. After hearing this, he feels that he will also be called "kinbei" in the future, which is even more compelling.

As for the depression of the old professor, he can understand very well. In fact, although the old man is a genius, he is not very useful in the fishing grounds. Finally, he has a black cover giant insect project, but Qin Shiou stopped because of the lack of raw materials. That is his best. Sorry.

  Hearing what the old professor said, Qin Shiou grinned and said: "These scallops are all high-quality relatives I imported from other fisheries. Of course the quality is good, and I don't want it if I don't."

  At present, there are mainly two scallops commonly used in major fisheries 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, that is, quality decline.

  The reasons for this are firstly the problem of germplasm degradation of this shellfish; secondly, the pollution of the breeding environment; thirdly, the problems of operation management, breeding density, etc.; fourthly, there is the problem of breeding.

Two kinds of bay scallops have been cultivated in North America for more than half a century. The Mexican bay scallops were introduced from Mexico. Due to the unstable political power of Lao Mo at the time, the number of introductions from the two countries was limited, and it was a nightmare that breeds one generation every six months. , So after more than half a century of artificial breeding, it is inevitable that inbreeding will occur.

  This is just like a person. The quality of children born from close relatives is difficult to guarantee. Over time, the breeding characteristics of shellfish will deteriorate. At first, Sanders thought that the fishery would encounter this problem, and he wanted to solve this problem to show his strength.

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

After seeing the quality of scallops, Sanders suggested that Qin Shiou could not engage in primitive farming, and start a seedling cultivation business. This is more profitable than primitive farming, because it comes quickly, so you don’t need to raise fish, shrimps, and scallops. Years or even years of output.

  Canada’s scallop industry is currently experiencing 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 for breeding, which is expensive.

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

  Qin Shiou thought for a while, this is also a good idea for development. Use the sea **** consciousness to transform the mother body, so that the fry, shrimp fry and shellfish produced are all high-quality, which can be regarded as the greatest use of gold fingers to make contributions to marine life.
