Embodiment 1

[0030] 1. Pond cleaning, disinfection and fertilization

[0031] Cleaning ponds and disinfection treatment of ponds shall be handled according to the routine method of disinfection of aquaculture clearing ponds, and the specific steps are as follows:

[0032] In winter, clear the pool and solidify the ridge to remove excess silt. The ridge height is 2-3m, and the sun and frost will crack the bottom mud and promote the oxidation of organic matter in the bottom mud. 10cm of water in late February, with quicklime 75-100kg / 666M 2 Or chlorine bleaching powder 10kg / 666M 2 Disinfect thoroughly to kill harmful organisms, pathogenic bacteria and parasites. After 10 days, enter the water 30cm, every 666M 2 Apply 100-200kg of decomposed organic manure or 15kg of phosphate fertilizer on the water surface, and stock the yellow catfish fry after one week.

[0033] 2. Seine settings

[0034] Set up a seine net in front of the main fish species yellow catfish baiting machine (see the stru...

Abstract

The invention belongs to the technical field of aquaculture, and relates to a method for mainly culturing yellow catfishes and carrying out polyculture on other feeding fishes in a pond. The method is characterized in that a new netting method is designed, various feeding fishes can be cultured in the yellow-head catfish main culturing pond in a polyculture mode according to local conditions, and the unit culturing efficiency of the yellow-head catfish main culturing pond can be improved greatly. The method mainly includes the steps that a purse net is erected in front of a main fish, namely the yellow-head catfish, feeding machine according to the feeding area covered by the feeding machine; preferentially, 80% bait fed by the feeding machine can fall in a region surrounded by the purse net under the breezeless condition, wherein the purse set is made of polyethylene, and is 60m in length, 4m in height and 4cm in mesh, dense-net cylindrical polyethylene net pieces are sewn at the bottom of the purse net, the diameter of each dense net piece is 6cm, cobblestone are arranged in the dense net pieces as sinkers, the purse net is fixed into a closed circle through bamboo poles, the foot line reaches bottom mud, and the head line is exposed of the water surface by 80-100cm. The invention further provides a coordinated culturing mode and a specific method.

Description

technical field [0001] The invention belongs to the technical field of aquaculture, and in particular relates to a method for mainly cultivating yellow catfish and other feeding fishes in a pond. Background technique [0002] There are various farming models of peltago catfish. At present, it is relatively mature, and the most popular and widely used methods are pond intensive culture, pond culture and net cage monoculture. The set culture of yellow catfish is mainly carried out in ponds of adult fish of four major domestic fishes or ponds of shrimps, crabs and soft-shelled turtles, and the amount of stocking shall not exceed 4500 fish / hm 2 , lower yields. The intensive cultivation mode of yellow catfish mainly includes monoculture in ponds, or interbreeding silver carp in the main pond for feeding on algae, or interbreeding a small amount of Chinese soft-shelled turtle in the main pond for higher economic benefits. , the Chinese soft-shelled turtle raised in nesting does...
