2. What procedures are required for fish processing?

Fish processing requires hygiene permits, health certificates, food permits, and environmental impact assessments.

3. What does a fish processing plant need?

You need a food production license, business license, and health license.

In addition to the site, labor, vehicles, and relevant processing procedures, a professional fish processing production line is also required. If it is a small production, 2-3 workers are enough to put it into production.

Production method: The purchased rotten fish will be processed initially, the internal organs, scales, etc. are removed, and then the fish meat is placed in a large vat and marinated with salt, artificial flavors and preservatives. (Sometimes the marinated fish with preservatives can be kept for 10 days before being cooked). After this processing, the fish workers put the fish into the faucet pot on the stove beside the street and boil the fish with water until it turns white. Then use a dustpan to scoop out the boiled fish and dry it. After the water vapor of the fish is filtered out, the fish workers place the fish in the pre-prepared smoking net and put it into the smoking stove that has been filled with thick smoke for a long time.

5. What kind of animal is the seahorse? A mammal B fish C mollusk D amphibian?

The main characteristics of fish: Fish live in water all their lives, have a spindle-shaped body, are mostly covered with scales, breathe with gills, and swim with fins. Fish have a spine made up of many vertebrae, which has the function of heat preservation and protection. The body temperature usually changes with the change of environmental temperature, and they are cold-blooded animals. Therefore, seahorses belong to fish. Amphibians live on land and water. The larvae breathe with gills, and the adults breathe with lungs, and the skin assists breathing. Mammals are characterized by viviparity and lactation. Reptiles are covered with keratin scales or armor, breathe with lungs, and their body temperature is not constant, and it changes with the external temperature. Therefore, seahorses belong to fish. Therefore, the answer is: B

6. Is it really hard to work in the fish processing factories in Hokkaido, Japan?

Fish processing is relatively hard work, and it is inevitable to do seafood processing work such as soaking in ice water for a long time. If you do this for a long time, a year or two, and get sick, it will not be worth it.

Wages in Hokkaido are already low, and the real estate agencies take a little bit out of the equation, so the actual payout is not much. Don't think that if Japanese old ladies can do it, you can't. They are hourly workers, working for a few hours and changing shifts. Those who are recruited there only work for a whole day, and the labor intensity is greater than in China, and seafood processing is relatively more tiring.

I advise you not to go. If you want to work and earn some money in Japan, go to Tokyo or Honshu, or choose a job that doesn't involve water to avoid getting into trouble.

7. What happened if the Z axis of my new woodworking machining center exceeds the positive software travel limit?

8. Briefly describe the main characteristics of cnidarians, flatworms, nematodes, annelids, mollusks, arthropods and fish?

Echinoderms: starfish Coelenterates: sea anemones, moon jellyfish Flatworms: Nematodes: roundworms Annelids: Molluscs: Arthropods: Fish: crucian carp Amphibians: Reptiles: chameleons, lizards Birds: swans, three-treasure birds, turtledoves, great tits, sparrows, woodpeckers, pigeons, peacocks, crows Mammals: humans, hares, platypuses, bamboo rats, red pandas, monkeys, hedgehogs, pangolins

9. Is it really hard to work in a fish processing factory in Hokkaido, Japan? How much is the annual salary?

Fish processing is relatively hard work, and it is inevitable to do seafood processing work such as soaking in ice water for a long time. If you do this for a long time, a year or two, and get sick, it will not be worth it.

The wages in Hokkaido are low to begin with, and the agents take a little more money in the middle, so the actual amount of money you get is not much. Don't think that if Japanese old ladies can do it, why can't you? They are hourly workers, working for a few hours, changing shifts, and those who are recruited to work there work for a whole day. The labor intensity is originally greater than in China, and seafood processing is relatively more tiring. I advise you not to go. If you want to work and earn some money in Japan, go to Tokyo or Honshu, or choose a job that doesn't involve water to avoid getting stigmatized.

10. Is the wastewater produced by gallnut processing harmful to fish? The water has turned black.

Gallnut is a commonly used traditional Chinese medicine in aquaculture. It has the effect of killing bacteria and preventing diseases. The color of water will change after use. Low concentration of gallnut extract has no harm to fish, but is beneficial.

The 48-hour half-lethal concentration of gallnut for carp is 1.1015 g/kg, and the safe concentration is 0.1102 g/kg.

It is still recommended that you take water samples to test whether the content of dissolved oxygen, hydrogen sulfide and ammonia nitrogen in the water exceeds the standard.
