Embodiment Construction
[0022] In order to make the purpose, technical solution and advantages of the present invention more clear, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the invention.
[0023] figure 1 It shows the implementation flow of the method for preventing and controlling predators in the pond cultivation of Chinese anchovy seedlings provided by the embodiment of the present invention.
[0024] The method includes the following steps:
[0025] Step S101, 1-2 days before the artificial insemination of the common anchovy, thoroughly disinfect the clear pond with a disinfectant composed of quicklime and bleach;
[0026] Step S102, performing water quality regulation and filtering treatment on the water source injected into the anchovy nursery pond;
[0027] Step S103, installin...

The invention belongs to the technical field of aquaculture and provides a coilia ectenes offspring pond breeding enemy prevention method. Before 1-2days of artificial insemination on a coilia ectenes, thorough disinfection and pond cleaning are carried out by adopting disinfecting drugs formed by mixing of quick lime and bleaching powder; water quality regulation and control and filtering treatment are carried out on a water source which is injected into a coilia ectenes nursery pond; enemy creature prevention devices are arranged on the periphery and above the coilia ectenes nursery pond; and each enemy creature prevention device is composed of a steel pipe pile body, a main wire, a steel wire rope and a rubber thread net. By means of the thorough disinfection and pond cleaning through the drugs, serious filtering on entering water and arrangement and optimization of the enemy creature prevention devices, troubles from enemy creatures are reduced to the maximum, seedling survival rates are improved, reliable guarantee is supplied to large-scale artificial breeding and industrialization development of the coilia ectenes, practicability is strong, and popularization and application value is strong.
Description
technical field [0001] The invention belongs to the technical field of aquaculture, and in particular relates to a method for preventing and controlling predators in pond cultivation of cuttlefish seedlings. Background technique [0002] There are many harmful organisms in the cultivation of earthen ponds. The harmful organisms in the early cultivation stage mainly include aquatic insects and larvae, such as water centipedes, water gnats and tadpoles, etc. The harmful organisms in the middle and later stages mainly include water birds, frogs, fierce fish and water rats Wait. Anti-bird devices and insecticides are usually used to kill the whole pond, but the prevention and control of this kind of predators other than waterfowl is neglected, and the method of using insecticides has certain damage to the ecological environment of the water body, and at the same time, the fry will be destroyed. The key bait organisms cultivated are killed, which has a great influence on the fry...
