Medaka fish are favored by farmers for their rapid growth and delicious meat. To raise medaka fish, we must first choose a suitable water quality environment, and the slightly alkaline water quality is more suitableSecondly, the water temperature needs to be controlled at 22-28 to ensure the comfort of fish growthIn addition, reasonable feeding should provide sufficient high-protein feed to ensure the nutritional needs of fish;Finally, keeping the water clean, changing the water regularly, and preventing diseases are the basic essentials of medaka farming.
1. The art and science of medaka farming.
The cultivation of medaka is not only a simple breeding process, it is an art that combines the wisdom of technology and experience.
First of all, the creation of the breeding environment needs to take into account the fluidity and oxidation degree of the water body, and a pool of living water can raise the vitality of the fish. Specifically, using an appropriate amount of yellow mud to adjust the bottom quality of the pond and make the pond water slightly alkaline, which is the first step to carefully regulate the water quality.
Secondly, medaka fish are unusually sensitive to water temperature. Like a child's thermometer, you have to monitor the water temperature every day to make sure they are in a "comfort zone". In case of abnormal heat and cold, it is necessary to take measures in time, whether it is to add a shade net, or to build a simple insulation shed, there are many skills, and you can always find a solution.
When it comes to feeding, you need to become a "nutritionist" to make sure that the fish plates are both delicious and nutritious. Corn flour, soybean cake flour, fish meal, etc., these are all popular delicacies of medaka. Regular and quantitative and scientific collocation, so that every fish can eat healthy and grow fast.
In addition, disease prevention and treatment is also an important lesson in breeding. You don't have to wait for the disease to knock on the door, you should keep the water clean, disinfect it regularly with lime, and add some Chinese herbs to prevent diseases, so that the pond can become a healthy paradise for medaka fish.
All in all, raising a pool of medaka requires a combination of care and wisdom. It's like tending to a crop, you need to have a wealth of knowledge and the patience to endure loneliness. The cultivation of medaka is such an unfathomable art and science.
Second, the general environment of agriculture, forestry, animal husbandry and fishery, medaka fishing.
From a broader perspective, medaka farming is not limited to the boundaries of ponds. It is closely related to agricultural technology, the economy, and the ecosystem as a whole. For example, the location of the farm should take into account the surrounding farmland, and rationally use agricultural and sideline products as fish feed to realize the recycling of resources. This not only reduces costs, but also enhances the sustainability of the agricultural chain.
The market economics of medaka fish farming is also a profound science. Understand market supply and demand, grasp sales channels, and fluctuations, each link can affect the profit and loss of breeding. As the saying goes, "know yourself and know your opponent, you will not be defeated in a hundred battles", and fish farmers should also become shrewd analysts of the market.
Speaking of technology, the rapid development of biotechnology and aquaculture technology in recent years has also brought new opportunities for medaka fish farming. For example, the use of biological filter technology to purify water quality, the use of automatic feeding machine to save labor, the application of these technologies has greatly improved the efficiency of breeding.
However, all technological and economic development is inseparable from respect and maintenance of the environment. The water resources on which medaka farming depends are facing a global water crisis. Therefore, farmers need to take water-saving measures, such as recirculating aquaculture systems, to reduce the consumption of water resources, which is a reverence for nature and a responsibility for the future.
On the basis of this expertise, each farmer also needs to gain personal experience in practice. There may not be any textbook that can teach you how to adjust the pH level of the pool water in certain weather, but in the mud and blisters, years of trial and error and observation are the most valuable treasure troves of experience.
Third, the problems and solutions in the wisdom of breeding.
Fish farmers will always encounter such and such problems on the road of medaka fish breeding. For example, sudden outbreaks of disease are often unexpected, and fish in ponds can die in large numbers overnight. Strategies to solve this problem require not only the support of modern medicine, but also the aid of folk wisdom. Just as the older generation of farmers will put bitter grass, wormwood and other Chinese herbs in the water to prevent diseases, the combination of such traditional knowledge and modern technology can often produce unexpected effects.
When it comes to operational processes, details often determine success or failure. Like embroidery, fish farming requires delicate operations, from seed selection, feeding, water change to disease prevention, every step of the way must be carefully arranged. You have to be like an experienced commander and take control of this ecological concerto.
What makes farming even more challenging may be the impermanence of natural factors. For example, when a rainstorm comes, the pond may be flooded in a few hoursDuring periods of drought, the drop in water levels can affect the growth of fish. In this case, fish farmers should have a countermeasure, perhaps to build flood control facilities in advance, or to prepare sufficient water storage equipment, in short, to find human wisdom in the laws of nature.
Finally, knowledge of agricultural management is also indispensable. Effective management can reduce costs and improve efficiency. As an old farmer likes to say: "Fish farming is not only about raising fish, but also about settling accounts." "Rational planning of feed use and careful calculation of water and electricity consumption are all management wisdom.
In short, medaka farming is a complex and challenging task that tests the patience, wisdom and determination of farmers. In this water, which has nourished the hearts and minds of countless generations of farmers, every fish farmer is the guardian of the ecology and the builder of the economy. Let's look for the fun of farming and the wisdom of life on the sparkling water.
