Pond greenhouse efficient micropterus salmoides fry cultivation and domestication method

Abstract

The invention discloses a pond greenhouse efficient micropterus salmoides fry cultivation and domestication method. The pond greenhouse efficient micropterus salmoides fry cultivation and domestication method comprises the following steps of constructing a culture pond, stocking micropterus salmoides fries, and carrying out cultivation and domestication in three stages. According to the pond greenhouse efficient micropterus salmoides fry cultivation and domestication method, the conditions for stocking the micropterus salmoides fries are controlled, constant-temperature living organism baits are artificially cultured through a bait feeding device, and after the micropterus salmoides fries are stocked, the micropterus salmoides fries are cultivated and domesticated step by step in stages through the bait feeding device; and different baits are fed to the micropterus salmoides fries in different stages of cultivation and domestication, the cultivated micropterus salmoides fries are healthy in physique and uniform in specification, the survival rate of micropterus salmoides fry cultivation and the domestication success rate are both 60% or above, large-specification high-quality fry guarantee is provided for small-scale scattered household largemouth bass cultivation, and the method has great practical application and production value.

Description

technical field [0001] The invention relates to the technical field of freshwater aquaculture, in particular, the invention relates to a method for cultivating and domesticating high-efficiency California perch seedlings in a pond greenhouse. Background technique [0002] California perch, scientific name of largemouth bass, native to North America, has the advantages of strong adaptability, fast growth, easy to catch, easy transportation, short breeding cycle, etc. In addition, the meat is delicious and tender, without intermuscular thorns, and the appearance is beautiful, so it is deeply cultivated. Welcomed by readers and consumers, it has become an important high-quality freshwater aquaculture species in China. After more than 30 years of development, my country has become the country with the largest production of largemouth bass in the world. [0003] In 2014, California perch was successfully cultured with full feed. Since then, it has gradually got rid of the shackl...

Problems solved by technology

However, water flower seedlings are generally cultivated in March to April, especially in Huzhou, Zhejiang. During this time period, the temperature is changeable, the temperature difference between day and night is large, and it is hot and cold, which can easily cause stress death of water flower seedlings, and even the whole pond has no water. seedling phenomenon

In addition, the water temperature is low during this time period, and the plankton suitable for the opening of water flower seedlings is not easy to reproduce in large numbers, and artificial feeding of frozen artemia nauplii and other commercial opening baits is unevenly splashed, resulting in some perch fry not being able to consume the bait required for normal growth Or, when there is insufficient bait, cannibalism often occurs. At the same time, due to the low temperature of frozen Artemia, perch water flower seedlings are prone to stress after ingestion, enteritis, diarrhea, ripening and death, which seriously affect the domestication and survival of sea bass water flower rate and aquaculture production

[0005] Chinese patent (CN108901950B) discloses a method for cultivating seabass seedlings in an industrialized manner. The water flower seedlings of seabass are domesticated by building an industrialized cement pool indoors. This method requires cement hardening and heating of the water body, and the cost is relatively high. For small It is not suitable for large-scale retail households to cultivate perch seedlings, and due to the large differences in environmental, temperature and other factors, its domestication method is not suitable for field breeding ponds
