First, how to judge fish starvation. Look at the length of time you eat. Feeding within 3 hours after feeding is normal, 2 hours or so after eating shows that the amount of feed is insufficient, and some fish are not full, should be increased appropriately at the time of the next vote; if extended to 4 hours has not finished, While the fish school has left the food market, it shows that there is more than enough food, and the amount of fish can be reduced next time.
Second, look at the size of fish growth. In April and May, the food intake of fish increases day by day. In the feeding plan of 1 week or 1 week, the changes in the beginning of week and weekend, or the beginning and end of ten days should be observed. If the number of shots is the same every day, at the end of the weekend or at the end of the day, it will be eaten within 2 hours. This indicates that the fish’s weight has increased, the food intake is large, and there is no enough food. It is necessary to increase the amount of feed until the start of November. Fishing can be used to identify and master this method.
Three to watch the water movement. After feeding, if the fish is not sick and frequently moves on the surface of the water, this is a manifestation of hunger. On the contrary, the fish will drill into the water after eating. In particular, fry or fingerlings swim in groups on the water, which is a sign of severe hunger. Commonly known as "race horse disease." If you want to feed immediately, block mad tours or you will die in large numbers. As for fish and fish, which are mainly eaten by plankton, they can observe the quality of water to determine whether they meet their growth requirements. When the water quality is thin, use fertilization methods to cultivate plankton. When the water quality is too fat, when the signs of deterioration appear, the water should be turned on immediately to increase the oxygen level. If necessary, the trichlorfon drugs will be used to kill plankton, and the water will become clear and thin, and then the water will be fertilized to cultivate the water. .
Second, how to prevent the occurrence of hunger and hunger. Must be committed to "four orders." There can't be anything to vote for, how much to vote, and no vote. Yu Yunyun: "Stop the day, white for three days." Some contractors tend to only look at the fields when they are busy, forgetting the heads of Tongtou, and many people stopping for food for a few days. Some concentrate their feed on one point less than 10 square meters, causing fish to eat unevenly and unevenly. , Can not reach the planned output; some of the feed storage is not strict, after the mold was not treated directly to feed, leading to outbreaks of fish disease, heavy losses. All these kinds of fish are raised. According to this, if we want to learn the scientific fish culture technology, we must first learn to identify the fish's hunger and satiety, adhere to quantitative, qualitative, positioning, timing of the "four definite" feeding methods, in order to achieve high yields.
Antibiotic:
A drug used to treat bacterial infections. Antibiotics have no effect on viral
infections. Originally, an antibiotic was a substance produced by one
microorganism that selectively inhibits the growth of another. Synthetic
antibiotics, usually chemically related to natural antibiotics, have since been
produced that accomplish comparable tasks.
Antimicrobial:
A drug used to treat a microbial infection(antibiotic drugs).
"Antimicrobial"
is a general term that refers to a group of drugs that includes antibiotics,
antifungals, antiprotozoals, and antivirals.
