Under the condition of good water temperature conditions, we will step up feeding, so that the fish will grow up as soon as possible, shorten the breeding cycle, and hope to reach the size of commercial fish in a shorter period of time than before, and improve production and efficiency. To grasp the timing of this feeding, so that the fish are highly productive, how to feed the fish is very important.
Why feeding is important
Feeding is not simply to sprinkle some feed into the fish pond, the method of feeding is improper, it will also affect the yield, which will affect our breeding efficiency. We can give an example:
Suppose you and your next-door neighbor Lao Wang are both fish farming, and your fish ponds are next to each other, the area is not much different, and the farming conditions are about the same. At the beginning of the year, you all bought 10,000 tilapia separately and put them in the fish pond. At the end of the year, a boss buys your fish at a price of 2.5 yuan / pound at the same time. It was so coincidental that your fish pond fished out 8,000 tilapia, and the neighbor Lao Wang also fished out 8,000 tilapia. When weighed, your fish has 8,000 pounds, while Lao Wang's has 12,000 pounds. In this way, you will lose 10,000 yuan less for Lao Wang.
Assuming that your farming conditions are the same, but Lao Wang's fish are heavier than yours, then the problem is feeding. Simply put: you didn't feed your fish fat, that is, your yield was not as high as others.
What kind of feeding method should be used
The general feeding principle is "more and better in the middle, less and fine at both ends". What is "more and better in the middle, less and fine at both ends"?
In the breeding of the year, more feeding in summer and autumn, and to feed well, spring and winter less feeding, to feed the concentrate. Why feed like this?
In other cases where the farming conditions are suitable, the growth speed and fatness of fish are related to their body metabolism, which in turn is related to temperature.
Summer and autumn fish appetite is strong, feeding more, at this time the water quality is susceptible to the impact of food residues and deterioration, coupled with if the quality of food is poor, it will make the fish have a risk of disease, it will not achieve the purpose of growth and fattening. Therefore, the bait in summer and autumn should not only be more, but also of good quality.
Fish eat less in spring and winter, but when entering the winter, fish need to be fattened to reserve energy for winter, and the feed at this time should be fine and nutritious;
In the spring, fish have to open their mouths to feed, and winter has already consumed most of the energy, at this time also need nutritious feed to replenish and restore physical strength.
Other considerations
First, feeding should choose the right feed according to the different growth stages of the fish. This is because the mouth size of different fish is not the same, the digestion and absorption capacity is not the same, in the fry stage, to choose the right fry to swallow the powder and small particles, in the adult fish breeding period to choose good quality, good nutrition granule material.
Second, when feeding, you should feed carefully and slowly. If it is artificial feeding, you should choose to fix it in a place (or build a food table), first gently tap the feed bucket or rhythmically beat the edge of the pond with a wooden stick, make a noise, make the fish form a habit of listening to the sound and seeking food, and then slowly feed, the fish eat a handful of feed, and then feed the next one. Most fish are found to no longer come to eat, and do not feed when the feed begins to sink to the bottom.
Third, different species of fish should choose a suitable feed for this fish. The most typical indicators are protein, such as carp, crucian carp and other omnivorous fish need feed protein content of about 33% is good, sturgeon, rainbow trout, catfish and other carnivorous fish in 40%-45%, grass carp, bream and other herbivorous fish need to be lower, about 25%. If you feed sturgeon and rainbow trout with grass carp feed, although the cost of feed is reduced, it is obvious that the nutrition does not meet the growth and development requirements, and the fish grows slowly.
