The most important thing about fish farming is the water used by the fish. , if the water quality is poor, it is likely to endanger the lives of the fish. Currently, many fish breeders seek fat water and thin water. So, what are fat water and thin water? What is the difference between them?
1. What is fat water and thin water?
Fat water: It shows that there are more organic matter in the water, and there are many types and large numbers of plankton. It grows vigorously, has high nutrients in the water, and consumes a lot of oxygen. The fish does not like to go to the bottom and floats easily. The visibility of the water in the pool is low and the color changes frequently.
Thin water: Generally it is living water with good water transparency, less plankton in the water, the color is generally light yellow or light green, the water quality is good, and there is no peculiar smell. In comparison, Shou Pond has less food in the water, and the water quality is better and clearer.
2. How to distinguish between thin water and fat water
Look at the water color: the water color of the pool can be divided into two categories, one is mainly yellow-brown water (Including turmeric, tea brown, reddish brown, brown with green); the other type is mainly green (including yellow-green, oil green, blue-green, tea green, green with brown). Both types have fat water quality. However, the yellow-brown water contains more fish that are easy to digest and has more plankton, so it is better than the green water.
Look at algae bloom: Algae bloom is caused by the comprehensive reaction of physical, chemical and biological factors in the pool. Its color and morphological characteristics are very obvious. For example: yellow-brown clouds represent fat water; dark green water filaments represent thin water. Therefore, the quality of water can be judged based on the shape of algae blooms.
Look at the oil film downwind: When it is difficult to observe the water bloom, the water quality can be judged based on the amount, color and shape of the oil film downwind. Fat ponds have a lot of oil film, and the viscous foaming changes day by day, appearing as light brown in the morning and brown to green in the afternoon (commonly known as "early red and night green"); on the contrary, it is a thin pond.
Look at water color changes: good water quality has monthly changes (10 days and half a month, light and dark changes) and daily changes (morning, afternoon and upper and lower winds); poor water quality does not change.
There are many weeds and dead fish on the water surface. The weeds grow quickly and the dead fish fester quickly. Such waters are extremely fat.
Many people dislike dark green water in family fish farming because they lose sight of the fish and lose the interest in sighting. In fact, fish in dark green water in autumn and winter rarely get sick. After this critical period, you will be better Isn’t it true that Jia Shen’s own work performance is also very good, so he can’t deny the green water in one round., and people like me who are more concerned about the growth and health of fish need green water more. Observation is not the main method. For players, it is unscrupulous to achieve their own fish-drying goals. There is no point in observing occasionally or not. Close is important. The so-called experts who are new to fish farming but are unwilling to rest or are so-called experts who are just half-baked often say that fish farming nourishes the mind, it doesn’t need to be so complicated, and that water quality is better, mainly relying on nitrifying bacteria filtration, etc. Indeed, Raising two hairy fish and feeding them one meal a day is really not complicated, the method determines the method, but don’t criticize other people’s methods, because you haven’t reached that stage yet, the so-called stupid and fearless person.
How does clean green water come from? First wipe off the old green moss, change the water, and then add green water. The green water drying method is to add disinfected sacrificial bloodworms to the basin after disinfection on the balcony to bask in the sun, and green water will form after a while.
Autumn is a season that promotes fatness. However, feeding live food in clear soup and water will bring about not weight gain but disease. This is an unfamiliar situation for many strangers. They only understand that trying to gain weight according to what others say is counterproductive. .
In summer, the sunshine is strong and the temperature is high. Green water will bring about problems such as lack of oxygen at night. Green water is not recommended in summer. In fact, green water control in summer is still a good choice for fish farming, but my home is south. There is no direct sunlight in the fish room in summer, but the sun shines in in autumn and winter, which is the time when raising fish is easy. In the past, some fish were particularly fond of green water, had little control and did not get sick.
The control of water quality and water temperature can be said to be the magic weapon of fish farming. As long as the breeder controls the water used by the fish and pays attention to the care of the fish in the daily breeding process, the fish will surely be protected. grow robustly.
