Problems solved by technology

[0003] At present, the bait for artificial breeding of puffer chrysanthemum is mainly seawater rotifers-artemia larvae-fresh seawater copepods, etc. Although these fresh baits are convenient to feed and easy to manage, they also have the following disadvantages: 1) It is difficult to match the peak period of cultivating fresh and live bait with the palatable bait time for fry cultivation, and it is also affected by environmental and weather conditions, especially the open bait—sea rotifers. There is often such a situation: when there is a large demand for seedling production, rotation The worm peak has not arrived, so it cannot be supplied in large quantities; and when the seedling production is not needed, there are a large number of rotifers in the bait cultivation pond; 2) The cultivation of seawater fresh bait requires certain earthen ponds, esp...

Embodiment Construction

[0014] Freshly hatched larvae of chrysanthemum fugu and larvae are kept in the hatching pond for 3-4 days and then transferred to the seedling breeding pond with a seedling density of 0.5-10,000 fish / m 3 , The water level of the pond for placing seedlings is 40cm; start adding water on the second day after the seedlings are released, and fill the water level to 120cm on the 4th day after the seedlings are released, and change the water on the 5th day after the seedlings are released. Change the water 2 / 3 every other day within a few days, and change the water 2 / 3 every day from 8-10 days after the seedlings are released; when the seedlings are released, the density of the aerosol stones is 1.5 / m 2 , In the later stage, the density of disperse stones is reduced to 1 / m 2 ; The water temperature is 21.5±0.5℃ when the seedlings are released, and the temperature is increased by 1.0℃ every 24 hours to 24.5±0.5℃;

Abstract

The invention relates to a feeding method of controllable bait for fries of Takifugu flavidus. The feeding method is characterized by comprising the following steps of: taking egg yolk as the bait during the initial stage when the fries are aged 2-10 days, and uniformly splashing and feeding in a full pool six times per day; taking Artemia larvae which are justly hatched as the bait when the fries are aged 7-10 days, and supplementing twice per day, wherein the feeding density is 2-3 larvae/ml; taking the Artemia larvae as the bait when the fries are aged 11-19 days, and supplementing twice per day, wherein the feeding density is 3-5 larvae/ml; taking frozen copepods as the bait when the fries are aged 14-19 days, uniformly splashing and feeding in the full pool, and supplementing six times per day, wherein the feeding density is 4-6 copepods/ml; taking the frozen copepods as the bait when the fries are aged 20-25 days, uniformly splashing and feeding in the full pool, and supplementing six times per day, wherein the feeding density is 4-6 copepods/ml; taking frozen large Artemia as the bait when the fries are aged 25-35 days, melting the bait at normal temperature, feeding to a bait table, and supplementing three times per day; and feeding compound feed when the fries are aged 30-35 days, placing 4-6 blocks of the compound feed on each bait table, and feeding twice per day, wherein the compound feed is kneaded into pastes.

Description

Technical field [0001] The invention relates to chrysanthemum puffer fish breeding, in particular to a method for feeding controllable bait of chrysanthemum puffer fish fry. Background technique [0002] Takifugu flavidus belongs to the order Takifugu, Fugu suborder, Takifugu, and Takifugu. It is mainly distributed in the East my country Sea, the Yellow Sea and the Bohai Sea. Crustaceans, shellfish and other invertebrates and small fish feed on, and have high nutritional value and medicinal value. Its muscles are as white as cream, fleshy, tender and delicious, rich in protein, and rich in nutrients. It is known as the top of the "Three Fresh Yangtze Rivers". At present, among the domestic puffer fish species, the market price of chrysanthemum puffer is the highest, reaching 150-200 yuan / kg. In addition, tetrodotoxin (TTX) extracted from the liver and gonads of chrysanthemum chrysanthemum is a strong neurotoxin. It is used to block Na in medicine and physiology. + An important d...
