How to freeze the fish caught in the river and feed them to my land, lucky cats and blue sharks? Ask for expert advice

The usual steps are:

1. After being collected in the wild or bought in the fish market (the road needs oxygen injection from the merchants), put it into a culture container. The water in the container is trapped and dechlorinated. The most basic condition is that the air pump is turned on.

2, roughly check the fish, there are dead, there are ulcers on the surface, and the abdomen is disproportionate (inward), pick it out.

3, a little salt, anti-inflammatory sterilization+vomiting.

4, container placed in a cool and ventilated place, avoid sunlight, insist on changing water every day.

5. When feeding, avoid a bag of nets and insist on feeding one by one. Not only can the body surface and abdomen of bait fish be checked one by one, but also the feeding amount of arowana can be controlled.

6. When feeding the young dragon, considering that the young dragon is fierce in predation and lacks agility, it can give some help, such as cutting off the tail fin, reducing the flexibility of the bait fish, facilitating the arowana to prey and avoiding being harmed by predation. The topic of no one helping arowana in the wild is not discussed here. The living conditions in the aquarium can't be compared with those in the wild.

7. The reason why it is emphasized that the wheat ear fish must be inspected one by one before entering the tank can not only be inspected one by one, but also prevent the fish lice from entering the tank.

8, fish lice, oval, flat, with hooks around the abdomen, once in the cylinder is extremely troublesome. After boarding the fish, the head, eyes, cheeks, neck, back, abdomen and fins swim with the fish. The fish couldn't stand the itch. It turned and tossed and bumped into the fish tank. . . Scales scattered, scalp, fish lips, dragon whiskers damaged, terrible.

I have had two experiences in dealing with fish lice. Toothbrush,No. deception net andNo. arowana are alive and not easy to cooperate with. I have been tossing for nearly an hour, sweating like a pig, and there is no result.

Finally, scrape off two chopsticks with a rope tied in the middle and fish them out with a net.

Summary results:

Instead of finding a better way to get it out, it is better to be alert to prevent fish lice from entering the tank.

Fish friends use the method of feeding after freezing, which can freeze internal and external parasites on the one hand; On the other hand, the freezing method saves trouble, the bait fish bought back is washed and frozen, and it is thawed when feeding, so there is no trouble in the daily management of live bait. But the hard-working owners who have the conditions still prefer live bait feeding. Because live bait and dead bait are different in nutrition.

There is also a small experience in the freezing method: the bait fish is inspected, washed and put into the freezer of the refrigerator. Take it out after about a minute. At this time, the fish has been basically freeze-dried, shaken and put into the freezer. In order to prevent it from freezing into a ball, you need to pry it open with a knife when feeding.
