Description

Safe and efficient ecological device for trapping bite in prawn culture pond

Technical Field

The utility model relates to a shrimp aquaculture field especially relates to a safe high-efficient ecological device of trapping water sting in shrimp aquaculture pond.

Background

Under the prawn soil pond breeding mode, the sting (the dragonfly larva) widely exists, the stocking survival rate of prawn seedlings is adversely affected, and the prawn seedlings within 3 centimeters are easily eaten by the dragonfly larva, so that the damage is great. Sting is a generic term for larvae of insects of the order Aeschynomena of the Insecta class; the body color is generally dark brown or dark green, and the research shows that: dragonfly and its larvae spread the Enterozoon (EHP) most harmfully, dragonfly itself, both adults and larvae carry enterozoon, young shrimp of small individuals become infected after ingestion by young shrimp, and young shrimp also become infected after ingestion by young shrimp of large individuals.

In China, particularly in soil pond culture of litopenaeus vannamei in the south China, dragonflies and larvae widely exist and frequently harm shrimp fries in the early stage of fry placing, and common farmers generally adopt a dipterex pest killing mode in production, so that not only is water and environment polluted, but also serious drug residue problems are generated, and the killing efficiency on water sting is low; therefore, an efficient, safe and ecological water sting trapping device and a killing method thereof are urgently needed to be established, the trapping device is removed out of a culture system after being killed, feeding loss and pathogen infection of the shrimp fries in the early stocking period are avoided, and the culture survival rate and yield of the prawns in the soil pond culture mode are improved.
