What do black fish eat?

Black fish like to eat feed made of small fish, shrimp, water fleas, animal offal, chicken intestines and so on, and even eat the same kind when hungry. In general, when raising black fish, we should first feed some natural bait, and then add some artificial feed such as earthworms and shrimp meat when the natural bait is insufficient.

Feeding method of black fish:

1. Types of feed

Frozen, fresh mixed fish, rotifers, water fleas and so on can be used as bait for black fish, but the feed must be made sure that the feed is not spoiled. The feed should be cut into small pieces. If it is frozen, it needs to be thawed when the temperature is about the same as the water temperature of the pool before feeding.

2. Feeding requirements

The daily feed should be 3% Mel 10% of the total weight of the fish. If the natural bait is insufficient, the breeders should add artificial bait. Generally, the amount of fish fry aged about 15 days will be doubled. At this time, some large crustaceans and chopped earthworms can be fed sooner or later, and the larvae can be fed with chopped low-quality mixed fish 20 days later. The specific feed can be changed according to the situation. Generally speaking, schools of fish are already full if they no longer go to the table to eat.

3. Timely rearing

If the black fish are not fed enough food, they will kill each other. In order to prevent the small fish from being eaten by the big fish when the feed is insufficient, the young fish whose body length can reach 3-4cm and whose age is about 20 days need to be raised separately from the big fish, and the juvenile fish should be raised separately at 5-6cm at the latest.

4. Artificial bait feeding

In general, if the natural bait of black fish is insufficient, artificial compound feed needs to be added. Generally, artificial bait is fed twice a day, and the weight of the feed is about 5% and 7% of the total body weight of the fish. The formula of artificial diet is as follows: 70% minced minced fish and shrimp, 20% bean powder, 5% yeast powder, 5% multivitamin mineral salt, 5% growth promoters and antibiotics, etc.

Feeding artificial compound bait needs to be trained when the fish are young. At the initial stage of feeding, earthworms or minced fish and shrimp meat can be put on the table, and then the table can be hung on the water surface about 20cm to induce fish fry to feed on their own. After the fry have formed the habit of feeding on the platform, other bait is gradually added, but during the feeding training, do not feed the fry live bait, so as not to disturb the feeding habit of fry.

The above is the introduction of what feed the black fish eats. I hope it will be helpful to everyone.
