Embodiment 1

[0027] refer to Figure 1-3 As shown, the present embodiment provides an indoor high-density circulating water overwintering device for larvae larvae, including: several culture ponds, water collection tanks, microfilters, balance ponds, biochemical treatment systems, oxygenation systems, and water replenishment systems , temperature control system;

[0028] The culture pond, water collection tank, microfilter, balance pond, and biochemical treatment system are connected in sequence, and the biochemical treatment system is connected to the culture pond; the oxygenation system is connected to the culture pond and the biochemical treatment system respectively. connected, the replenishment pool and the temperature control system are connected to the balance pool;

[0029] Wherein, each of the culture ponds is provided with an attachment base suspension bracket, and several layers of attachment bases are arranged on the attachment base suspension bracket.

[0030] The culture po...

Embodiment 2

[0042] refer to Figure 4 As shown, the present embodiment provides a method for surviving the winter in the indoor high-density circulating water of the larvae of the single-ringed wettle, which specifically includes:

[0043] Seed release: From September to mid-October every year, first place the attachment base covered with fine sand, and fully moisten the fine sand with aquaculture seawater; then release young weetids on the surface of the sand layer, with a density of no more than 1,000 heads / square meters (measured by sand area).

[0044] In this embodiment, in mid-October, first place the attachment base covered with fine sand, and fully moisten it with aquaculture seawater; then put 5,000 heads / kg of average size larvae on the surface of the sand layer, with a density of 1,000 heads / square meter (based on sand area).

[0045] Warming up of the device: After the larvae dive into the sand, the breeding pond, biofilter, balance pond and replenishment pond are filled wi...

Abstract

The invention discloses an indoor high-density circulating water overwintering device and method of the young Urechis unicinctus of Urechis unicinctus. The overwintering device comprises a plurality of culture ponds, a water collection tank, a microfiltration machine, a balance pond, a biochemical treatment system, an oxygen increasing system, a water supplementing system and a temperature control system, wherein the culture ponds, the water collection tank, the microfiltration machine, the balance pond and the biochemical treatment system are connected in sequence; the biochemical treatment system is connected with the culture ponds; the oxygen increasing system is independently connected with the culture ponds and the biochemical treatment system;a water supplementing pond, the temperature control system and the balance pond are connected; and in each culture pond, an attaching base suspension bracket is arranged and is provided with multiple layers of attaching bases. The overwintering device changes an existing plane culture mode of the Urechis unicinctus, improves unit water body culture density, is favorable for discharging residual feed, faeces and the like, and improves the living environment of the Urechis unicinctus. In addition, circulating water culture is low in a water changing quantity, an environment protection temperature control means is adopted, and therefore, pollution discharge is reduced while a temperature control cost is lowered.

Description

technical field [0001] The invention relates to the technical field of overwintering breeding of aquatic animals, in particular to an indoor high-density circulating water overwintering device and method for young weltweeds. Background technique [0002] Commonly known as "sea intestines", the single-ringed weed has the living habit of diving in sand and filtering food. When the water temperature is higher than 27°C or lower than 5°C, its feeding decreases or even stops, that is, it "closes its eyes". It has two big and small breeding seasons of spring and autumn. Spring seedlings are generally used in production (starting from April to May), and seedlings are cast in the autumn of the current year (September to October) or spring seedlings of the next year (March to May). To develop. [0003] Seedlings cast in spring mostly use indoor cement pools to overwinter directly with sand, and there are many problems. First, the seedling preservation workshop is generally on the c...
