① First of all, if we want to engage in pond culture, we should know the traditional "eight-character intensive breeding method". This is the basic technology that a person engaged in pond culture should master. "Eight-character intensive cultivation method" is the production technology of pond culture, which is summarized into eight words in our long-term production practice, namely "
water, species, bait, density, mixing, wheel, prevention and management
".
"
water
"refers to the environmental conditions of fish ponds, including the quality of water sources, the area and depth of ponds, and the surrounding environment. High-quality fish-raising water body requires suitable water depth, moderate area, good water source and fresh water quality.
"species
" refers to the varieties we breed. In pond culture, we require that the cultivated varieties should not only be complete and abundant, but also have appropriate specifications, strong physique, excellent variety quality and good genetic performance. Only in this way can we have good production performance.
"bait"
refers to the bait for fish farming, which includes not only the feed we artificially feed, but also the natural bait in the pond. If you want fish to grow well, you must ensure that the bait supply of fish is sufficient.
"density
" means that the density of pond culture should be reasonable. The stocking density is too thin and the growth is fast, but the water space can't be fully utilized and the total output can't go up. However, if the stocking density is too high, it may grow slowly, or even suffer from hypoxia and flooding.
"
mixed
"refers to the mixing and stocking of different species and specifications of fish in pond culture. This is an effective means to make full use of water space and all kinds of bait in the pond.
"
wheel
"refers to rotation, that is, wheel catching and wheel releasing. This is an effective means to make full use of water space, maintain reasonable culture density and increase pond yield.
"
prevention
"mainly refers to the prevention of fish diseases, and the prevention of fish from escaping, being stolen and being preyed by natural enemies.
"
management
"refers to the daily management and inspection of fish ponds and fish farming.
② Secondly, we say that to raise fish well, we must raise water first. The water here refers to the water quality of the pond. Generally speaking, through the management of fish pond water quality, the water quality of fish ponds should achieve the characteristics of "
fat, lively, tender and refreshing"
.
fertilizer
means that the water body is rich in organic matter and nutrients, so that the natural bait "plankton" of fish will be rich in the water body.
liveliness
means that the color of water body changes frequently, and the dominant species of zooplankton appear alternately.
tender
means that the water quality of the pond is fresh and not aging.
cool
means that the dissolved oxygen in the pond is sufficient and the transparency of the water body is appropriate.
③ In addition, there is another important technique in fish culture, that is, how to feed the fish. Don't underestimate this point. Good feeding technology can not only save costs and improve benefits, but also promote fish growth and prevent fish diseases. To feed, we should master the feeding techniques of "
three looking, four determining, and" even, sufficient and good "
.
Three inspections
refers to looking at the water quality of the pond, the weather, and the feeding activities of fish, and then determining the feed to be fed and the quantity.
Four determinations
are designated quality, quantity, location and timing feeding. That is, to ensure the quality of the feed, the number of the feed increases with the growth of the fish, and it is fed at a fixed position and time.
even and good
means that the quantity and rhythm of feed should be even, and the feed should be sufficient, with good quality and high nutritional value.
Of course, these are just the basic skills that fish farmers should have, and as a qualified fish farmer. There should also be support, artificial reproduction of fish species, and cultivation techniques. Prevention and control technology of fish diseases. And artificial fishing technology. In some places, the more fish you have to learn, the more skills you have to learn. In view of the space, I won't go into details here.
