Technology for cultivating takifugu flavidus summer fingerlings in cement pond of simple plastic greenhouse

Abstract

Simple plastic greenhouse cement pond cultivation technology of chrysanthemum yellow oriental fugu summer flower fish species, using cement pond, with a bow-shaped ring top on the top, which is characterized in that the bow-shaped ring top is covered with a dimmable shade film, and the air head density in the cement pond is 1-1.5 / m2, the stocking specification is 10-12mm / tail in total length, the stocking density is 1000-1500 tails / m2, the water level is 70cm when seedlings are released, and 20cm of new water is injected every day from the next day, and it is filled up after 4 days, and every other day from the 5th day. Change the water 50% every day. After 10-15 days of breeding, clean up the bait debris and fish excrement. The water quality indicators are seawater salinity 8-12‰, water temperature 25-28℃, dissolved oxygen greater than 5mg / L, PH 7.5-8.5 In the early stage, the fry were fed with medium-sized Cladocera and copepods, and in the middle stage, the fry were fed with frozen Artemia. The total length of the fry reached 30mm. The frozen Artemia transitioned to the compound feed, and all the eel feed was fed after 3-4 days of the transition.

Description

Technical field [0001] The present invention involves aquaculture, especially a method of cultivating chrysanthemums and fish species of chrysanthemums. Background technique [0002] Takifuguguflavidus belongs to the shape of a 鲀 鲀, Aya, 鲀 鲀, oriental 鲀, mainly distributed in the East my country Sea, Yellow Sea and Bohai Sea. Class, shellfish and other vertebrates and small fish are eaten. They have high nutritional value and medicinal value. They are known as the "Three Fresh of the Yangtze River".Its muscles are as white as frost, the meat is delicious, fresh and delicious, rich in protein, rich in nutrition. It is determined that the protein contains 18.7 grams per 100 grams of muscles, which is higher than the yellow croaker.The least one, in addition, is rich in vitamins, minerals, and a variety of trace elements that are beneficial to the human body. Its internal organs contain toxic neurivorouss, which are called riversal toxins (TTX).Application value, the price of perch...

Problems solved by technology

In view of good economic value, practical value and biological characteristics, the artificial breeding of chrysanthemum-yellow oriental fugu has gradually risen. Large-scale breeding of chrysanthemum-yellow oriental fugu requires a large number of fish species. Pond cultivation method, this method is obviously restricted by natural climate conditions and affected by the bottom quality of the pond, there are low cultivation survival rate (40-60%), slow growth of fry due to low temperature (40-50 days), large area The problem
