Embodiment 1

[0059] The selected pond has an area of ​​160 mu, 10.7 hectares, a length of 620 meters (EW direction), and a width of 172 meters (NS). A rectangular pond with an average water depth of 2.3 meters. From April to October, the main wind direction and the length of the main selected cable are 120 meters, the pile cable is 15 meters, and the piles are set up at an interval of 10 meters from the pool.

[0060] The distance between the unit cages in rows is 50 meters, and 30 cage units form a row. Control group: a small pond near the pond. The stocking density is 500 heads / cage, or 50,000 heads / ha, the body length is about 1.1cm (weight: 4.8g / head), and the breeding is carried out according to the traditional method, which is measured after 7 months. The results are shown in the table below.

Abstract

The invention discloses a bioreactor for large-scale pond rearing of trepang and a construction method thereof. Net cage units are constructed, transporting and transplanting processes are conducted gradually, a pond forms diversified ecological same spaces which are isolated and interrelated, the increase of the motility of the trepang is thus facilitated, and the trepang is avoided to be excessively centralized in one block. Through the shielding effect on the water surface, gulfweed is cultivated, the trepang is fed at any time, the feed coefficient is increased, and defects existing in the exiting large-scale trepang pond rearing technology are avoided. According to the construction principle of the bioreactor, a favorable growth environment is provided, a suitable feed industry is provided, the bioreactor for large-scale pond rearing of the trepang is formed, and efficient rearing of the trepang is achieved.

Description

technical field [0001] The invention relates to a bioreactor for cultivating sea cucumbers in large ponds and a construction method thereof, belonging to the technical field of seawater cultivation. Background technique [0002] Bioreactor refers to any manufacturing or engineering equipment that provides a biologically active environment. The bioreactor was first applied in the fermentation industry. The microorganisms were designed according to the technology in the fermentation tank to produce a large amount of products. After separation and purification, they became products to meet human needs; enzyme reactor. Aiming at the high-efficiency cultivation of microalgae, plant cells, and photosynthetic bacteria that require photosynthesis, the photobioreactor developed can obtain suitable temperature, light, and substances for the culture under temperature control, light control, cycle control, and aeration and agitation. Exchange and other environmental conditions, to ach...
