Ocean tidal flat original ecology raising method

Abstract

The invention discloses an ocean tidal flat original ecology raising method. The method includes: enclosing, building fields, releasing and tending on a coastal tidal flat. Enclosing includes: enclosing a raising area with a double-layer overall-sealed fence with typhoon-resisting and anti-escaping functions so as to perform all-weather protection. Building fields, namely a raising area ecological environment includes: building a fry nursing field, a feeding field, an inhabit field and an overwintering field. Releasing includes: manually releasing large economical organism varieties and artificially raising and breeding tidal flat aquatic organisms so as to build a raising area natural ecology system. Tending includes: allowing for natural fry nursing, natural feeding, natural pollution discharge and natural growth of the tidal flat organisms in the raising area natural ecology system. Dynamic balancing management is implemented according to the change of natural environments and relations among organism groups. The method is low in investment, high in yield, simple and practical, relative balance of environmental protection and resource utilization is achieved, ocean aquatic resources decreasing year by year are repaired, and harmonic development of man and nature is achieved.

Description

technical field [0001] The invention relates to a tidal flat breeding method. Specifically, the method follows the natural law, provides the required growth conditions according to the growth characteristics of the organism, fully exerts its natural growth instinct, and combines the dynamic management of the natural environment change and the biological growth process Measures to carry out tidal flat ecological grazing production operations. Background technique [0002] At present, the marine aquaculture methods mainly include reclamation seapony aquaculture, tidal flat low-dam high-net aquaculture, marine cage aquaculture and industrial aquaculture. These traditional aquaculture methods have many common problems: 1. High input cost and low output efficiency; 2. The breeding bait is mainly small fish, small shrimp, small crab and aquatic resource seedlings. The waste of resources is large, causing a vicious cycle of marine resources, and the gain outweighs the gain; 3. Due ...

Problems solved by technology

[0002] At present, the marine aquaculture methods mainly include reclamation seapony aquaculture, tidal flat low-dam high-net aquaculture, marine cage aquaculture and industrial aquaculture. These traditional aquaculture methods have many common problems: 1. High input cost and low output efficiency; 2. The breeding bait is mainly small fish, small shrimp, small crab and aquatic resource seedlings. The waste of resources is large, causing a vicious cycle of marine resources, and the gain outweighs the gain; 3. Due to intensive breeding, self-pollution cannot be solved, and the incidence rate is high and spreads quickly and 4. The environmental factors of the breeding grounds are not complete, the nutrition of artificial feeding is not comprehensive, the yield is low, and the quality is poor

Specific manifestations are resource waste, high energy consumption, high incidence of breeding and rapid spread, low yield and poor quality, serious environmental damage and pollution, and people's large-scale unlimited fishing of marine natural resources through high-tech means, resulting in a sharp decline in marine aquatic resources. Restricting the sustainable development of marine economy

[0003] However, the existing value-added measures for marine aquatic resources, such as artificial exile and artificial fish reefs, are immature in technology, and the introduction of biological seedlings is not in place, resulting in marine ecological imbalance. Artificial fish reefs have little effect on the value-added of marine resources, and a large amount of investment , but due to the scarcity of marine resources, there is a situation where there are no fish to play

[0004] The above causes are caused by human beings, and there is a serious imbalance between environmental protection and resource utilization.
