What are the benefits of baby fish farming?I want to farm baby fish

The Hyatt Regency Hangzhou recently released a new menu that removes all shark fins. As early as September last year, Hangzhou Huanglong Hotel shouted "farewell shark fin" on the grounds of environmental protection, which became a good story for a while. Since last year, shark fin dishes have gradually disappeared from the menus of Hangzhou's high-star hotels and boutique restaurants, and more and more hotels and restaurants no longer provide, produce and sell shark fin dishes in any way.

After shark fin disappears from the table, what to eat at a high-end banquet?What kind of ingredients are not only rich in nutritional value, good taste, but also decent when treated?The imitation wild baby fish with a treasure has quietly replaced the status of swallow abalone wings with the value of "live ginseng in the water" and has become a newly popular nourishing upstart.

Baby fish is a precious aquatic animal that is the key development of China's characteristic agriculture, its meat is delicate, the flavor is unique, the nutritional value is very high, it is highly respected by people, and it has become a precious delicacy of high-end hotels and hotels. In Hong Kong, Taiwan, Southeast Asia and other places, it is regarded as a high-end and precious tonic. The annual market capacity of the country is more than 10,000 tons, and the current market supply is about 20 tons.

If domestic sales and foreign trade go hand in hand, the market capacity will expand. The stock of natural salamander resources is extremely scarce. The second-generation giant salamander is currently 2,000 yuan per kilogram, and the market prospect is very promising.

Seizing the development opportunity of scarce giant salamander resources and huge domestic and foreign market demand, the development of commercial aquaculture of giant salamander is an emerging industry with great potential, which will produce significant economic and social benefits.

1. Baby fish like to eat live small animals. Water earthworms are ideal feed, and a small amount can be put in every other dayYou can also put the earthworm into a single layer of gauze to wrap it, hang it in the water with a rope, the earthworm will stick out part of its body from the gauze gap, and the baby fish will swim to pull food. In addition, tadpoles, tadpoles, daphnia, etc., are also favorite foods of baby fish.

When small animals are inactive, lean pork can also be cut into small pieces and fed. However, care should be taken not to feed too much, and it is advisable to have no residual food to prevent food from rotting and affecting the water quality.

2. Clean pool water is better for feeding water, and well water is also applicable. If you use tap water, leave it for 3-5 days before using it, otherwise the chlorine gas retained in the tap water will cause salamander poisoning and death. Changing the water is a regular management task.

Keeping the water fresh and clean is conducive to the normal life of salamander. The water is changed every 2-3 weeks in winter and every 3-5 days in other seasons.

3. The baby fish can be raised in a large glass fish tank, which is convenient for observing its activities. The bottom of the tank is covered with washed sand and gravel, 30 cm deep pool water or well water is injected, and a small amount of aquatic plants such as goldfish algae are put in, and the ecological environment is similar to that of the fishing site. Sand and gravel have the effect of adsorbing dirt;Aquatic plants can photosynthesize, increase the oxygen content in the water, and provide spawning for salamanders.

4. Precautions for breeding baby fish: when we feed baby fish, try to use some natural bait-based, what insect meat, fish, shellfish are some good choices, feed us once in the morning and evening, try to keep feeding at about seven o'clock in the morning, keep it at about ten o'clock at night, at the same time we have to clean up some of the bait left over from the last time, so as not to affect the normal growth of the baby fish and affect its living environment. The density of the salamander breeding pond should be determined according to the size of the breeding and the water source, under normal circumstances, if it is a seedling, we can make the salamander's range of activities as small as possible, at this time its survivability is relatively poor, the stocking density can be appropriately larger, so that we can carry out centralized management of them.

When the baby fish grows up, we will try to make it as dense as possible, because at this time its survivability is relatively strong, if we put a large number of baby fish, it will cause them to fight each other for food, which will also bring you unnecessary losses.
