Inter-tidal zone fish deposition habitat and self-purification underground pipeline ecological breeding system

Abstract

The invention discloses an inter-tidal zone fish deposition habitat and self-purification underground pipeline ecological breeding system which is mainly composed of an impounding reservoir, a pipeline system, a bait feeding window and a deposition living box. The bait feeding window is connected with the deposition living box through a fish channel, the bottom of the bait feeding window is connected with a clean water draining pipe, and the impounding reservoir is connected with the bait feeding window and the deposition living box through a pipeline water inlet system. The breeding system is improved based on an original patent according to the actual using situation, and a mode that a bred fish dining room is relatively separated from a fish living room is established. An original vertical pipe is replaced by the deposition living box, a natural deposition habitat is provided, and soil self-purification capability is improved. An original managing window is replaced by the bait feeding window, so that the self-purification capability of the system is improved. The utilization efficiency of tide energy is improved. By means of the inter-tidal zone fish deposition habitat and self-purification underground pipeline ecological breeding system, the health and disease resistance capability of the bred fishes can be improved, and the rate of survival and fish quality are improved.

Description

technical field [0001] The invention relates to the technical field of intertidal fish breeding, in particular to an intertidal fish depositional habitat and self-purifying underground pipeline ecological breeding system. Background technique [0002] The invention patent obtained by the patent applicant "a buried water self-renewing tidal flat pipe network fish ecological breeding system" (Patent No. 2010 1 0606442.2, published on June 29, 2011) discloses a fish ecological The breeding system is mainly composed of four parts: the water storage area, the underground pipe network, the exchange pipe and the management window. It adopts the underground pipe network to breed animals, and the breeding water can be automatically renewed. The water and air exchange and natural bait collection are realized through the exchange pipe. The management window implements daily management. The system is simple in structure and easy to operate. It not only protects the mangroves, does not ...

Problems solved by technology

However, in actual application, it was found that the predation, excretion and activities of benthic fishes in the original system were all in the same hard pipe network space completely made of PVC pipes and cement. There was no natural sediment environment, and the water demand was large. The water quality is difficult to control, prone to outbreaks of fish diseases, the output is unstable, and there is a certain difference between the quality of the output fish and wild fish; when the low tide period meets high temperature and high salinity weather conditions, the system farmed fish is vulnerable to predators Biological attack, resulting in the death of a considerable part of the fish

After careful observation, the lack of natural habitat (silt) in the fish ecological breeding system is the main factor, which affects the health and disease resistance of fish; in addition, the management window has poor self-purification ability, which leads to the decline of water quality and easily causes fish diseases. It is also the original system a shortcoming of
