Shrimp-fish-shellfish-algae multiple cultivation and water quality biological regulate and control system thereof

Abstract

The invention provides a shrimp-fish-shellfish-alga multi-unit culture and aquatic organism regulation system thereof. A shrimp culture zone, a fish culture zone, a shellfish culture zone, a large scale alga cultivation zone, a probiotics and microalga culture zone, a water processing zone and an emergency drainage system are arranged in a closed water circulation culture system, wherein the culture water circulates in different culture and water processing units. As the water circulates in different culture units and is utilized in multiple levels by various aquatic organisms of different trophic level and ecological niche, the system gives the various aquatic organisms full play to the positive bait resource complementarity, prevents the aquatic organisms from directly competing on living space and dissolved oxygen and reduces the mutual damage caused by organic remains and metabolic waste, achieves the 'self-modification' and 'biomanipulation' of the culture environment, enables the environment itself to recover from the pollution in culture process, and decontaminates the seawater culture environment.

Description

technical field [0001] The invention belongs to aquaculture, in particular to a shrimp-fish-shellfish-algae culture and a water quality biological control system. Background technique [0002] Shrimp is one of the main aquaculture species in my country. In 1992, my country's shrimp production once reached 22 × 104 tons. However, in 1993, a large-scale outbreak of a national shrimp epidemic occurred. In 1994, the national shrimp production was only 5.5 × 104 tons. Since then, the majority of scientific and technological workers have carried out extensive research on shrimp farming methods. Closed circulation integrated aquaculture system, Xie Shutao et al. introduced a pollution-free and high-efficiency disease prevention cultivation method for prawns, Li Jian et al. proposed a clean prawn cultivation mode that uses microorganisms to purify water quality, Gary et al. Security is discussed. Balasubramanian, Gopalakrishnan and Nair respectively evaluated the ecological regula...

AI Technical Summary

Problems solved by technology

However, when two or more kinds of organisms are mixed in the same water body, on the one hand, the cultured organisms will have direct competition for living space and dissolved oxygen, as well as mutual harm caused by their own metabolic waste.

On the other hand, polyphagous omnivorous fish can eat high-quality prawn feed, resulting in a relatively low utilization rate of input feed for prawns.
