Specific operation in parent fish culture pond
The daily operation of managers in the culture pond will directly affect the feeding and cultivation of parent fish. As the large yellow croaker is very timid and easily frightened, the noise caused by the walking of the management in the breeding room, the bait, the holding of tools, and the sudden change of light caused by the opening of the door may cause the large yellow croaker not to eat or eat less for a while, and may cause wild swimming, so as to hit the pool wall or jump out of the pool, causing injury or death, affecting the normal development of the gonads of the parent fish.

Several causes and prevention of floating head of fish
The "floating head" of fish is a common phenomenon in aquaculture production, and it is also an important sign to judge whether fish get sick or not and the change of water quality. However, many farmers do not understand the cause after discovering the "floating head" of pond fish, and drug administration only based on "experience" is often ineffective and even lead to a large number of deaths. In fact, the floating head of fish can be caused by a variety of factors. According to the cause, "floating head" can be divided into the following three types. The anoxic floating head is due to the low content of dissolved oxygen in the water and the farmed fish swim to a relatively high surface.

Ten precautions in the peak growing season of adult fish
First, to prevent starvation of adult fish in the growing season, large food intake, should be more bait and feeding. Fish ponds dominated by grass, crucian carp and tilapia should be fed with mixed feed such as wheat bran, cake, soybean dregs and fresh feed such as tender grass and plant stems and leaves. In general, daily raw materials account for 10% of the total fish in the pond. 2. the amount of fertilizer required for fish in the peak growing season accounts for 80% of the total fertilizer application, so every 5 ~ 7 days, 60 kg ~ 100 kg of fully fermented human and animal manure and 2% of nitrogen and phosphorus fertilizer are applied per mu.

Key points of cultivation techniques of parent fish in winter
The cultivation of parent fish can be divided into postpartum nursing, autumn cultivation, winter cultivation and spring cultivation. Due to the low temperature in winter, the activities of parent fish are reduced, the feeding ability is weak, and fish diseases are easy to occur. If it is poorly managed, it will have a great impact on artificial hatching, fry production, adult fish culture and other production links in the coming year. The main technical points for the cultivation of parent fish in winter are as follows: first, the selection of parent fish pond requires sufficient water source, flat bottom, shelter from the wind and sun, water conservation and heat preservation, with an area of 10-15 mu.

Is the late autumn shoot coming out of the orange tree in Shatang now?
Excuse me, are the late autumn shoots coming out now? My Shatang tangerine will be trial-produced next year. Will it be released or erased this time? When is the flower bud differentiation? When does the ring cut start? At present, it is late autumn, about 20 days from the Beginning of Winter's festival. Sand sugar orange in the late autumn, of course, belongs to the late autumn shoot. The initiation time of flower bud differentiation of sand sugar orange usually begins at the end of October or the beginning of November. That is, before this time, the non-autumn shoots of the plants that need to be arranged to hang fruit the following year should be fully mature before the flower bud differentiation period.

Malnutrition causes fish diseases
With the rapid development of factory breeding, formula feed is used more and more widely. However, some formula feed can not meet the nutritional needs of fish due to raw material problems or preparation technical problems. In particular, the feed designed and produced by small feed factories and farmers may cause undernutrition or overnutrition, which will lead to the decline of fish physique and, in serious cases, fish death. This paper will discuss the causes of fish diseases from the aspect of nutrition, in order to guide farmers to take timely measures to prevent fish diseases in culture production.

High-quality fish forage-- the key technique for high-yield cultivation of zedoary
Zedoary is an annual or perennial herb of the genus Asteraceae lettuce. It is rich in nutrients, and its crude protein content is 35% and 40% higher than that of Sudan grass, which is known as the "king of forage". The tender leaves of zedoary vegetables contain many carbohydrates, have good palatability, and the utilization rate is almost as high as 100%. It is an excellent green feed for fish. Zedoary vegetable is the best "green forage" for ryegrass and Sudan grass before the off-season and Sudan grass peak season. It can not only serve as the "staple food" of herbivorous fish, but also serve as a "delicacy" for cultivating green, grass, carp and other fish species. Cultivation characteristics

Definition and classification of fish medicine
Drugs refer to substances that are used to prevent, treat, diagnose diseases and assist the body to restore normal function. As the name implies, fishery medicine refers to the drugs specially used in fishery to ensure the healthy growth of aquatic animals and plants. Therefore, its scope of application is limited to the aquaculture industry, while the substances used in capture fisheries and fishery products processing industry are not included in the category of fishery drugs. Modern aquaculture fisheries are divided into two parts: aquaculture of fish, shrimp, shellfish, turtles and soft-shelled turtles, and aquaculture of aquatic plant species dominated by algae such as porphyra and kelp.

Mixed culture of fish and geese can increase economic benefit by 30%.
Three-dimensional breeding of fish and geese is a three-dimensional ecological breeding model of poultry breeding and fishery comprehensive management. According to comparison, under the same conditions, the economic income of comprehensive culture of fish and geese is about 30% higher than that of fish and geese. First, the benefits of three-dimensional culture of fish and geese. 1. Goose is a fully automatic energy-saving and efficient aerator for fish ponds. When mixed culture of fish and geese, breeders do not need to worry about the lack of oxygen caused by weather change, because in the event of climate change, geese will jump into the water to take a bath and chase, causing spray to tumble. It has a very good effect on increasing oxygen in fish ponds.

Key Techniques for Reducing the Casualties of Parental Fish
The main factors leading to the death and injury of spawning parent fish are as follows: one is that the parent fish consumes a lot of physical energy in the process of spawning and reproduction, and the side effects of spawning drugs make the resistance ability of the parent fish decrease. If the fish body is injured, the pathogen infection is easy to cause diseases; the other is that the parent fish is poor in constitution, or the water temperature changes greatly during spawning, and the dosage of spawning drugs is improper. The parent fish cannot spawn normally, and thus causes its own physiological activity disorder and death. Therefore, in production, it is necessary to effectively grasp the prenatal cultivation of parent fish, so that the gonad development of parent fish is normal.

Prevention and treatment of lung choking in turtles
Tortoises are divided into dry turtles, aquatic turtles and semi-aquatic turtles. Dry turtles live on land or mountain areas all the year round. Aquatic turtles live in rivers, lakes, ditches, streams and farmland. Semi-aquatic turtles live in the environment where water and land meet all the year round. Under natural conditions, turtles are not easy to choke water or suffocate and die, but under artificial breeding conditions, due to different species or environmental conditions, or artificial improper ways to cause turtle lungs to choke water and die, but sometimes occur in farms. 1. Reasons for choking water 1. Artificial breeding ponds are often small, if the water quality deteriorates
