Embodiment Construction

[0032] The present invention will be further described in detail below with reference to the embodiments, so that those skilled in the art can implement it with reference to the text of the description.

[0033] It should be understood that terms such as "having", "including" and "including" used herein do not equate the presence or addition of one or more other elements or combinations thereof.

[0034] The present invention provides a water-saving and synergistic method for intensively raising ornamental fish in turtle ponds, which includes the following steps:

[0035] Pre-treat and sun water the turtle ponds before stocking;

[0036] In late April, in the soft-shelled turtle ponds, the total length of 2.8-3cm Huangman arowana and blue arowana was stocked, and the total stocking density of Huangman arowana and blue arowana was no more than 10 fish / m 2 ;

[0037] In the first ten days of May, stock soft-shelled turtles with an average weight of 140-155g into the soft-shelled turtle po...

Abstract

The invention discloses a water-saving synergy method for intercropping spectacular fish in an intensified turtle pond. The method comprises the following steps of conducting pretreatment on the turtle pond and airing water before stocking is conducted; in the last ten days of April, stocking gold gourami and blue gourami in the turtle pond, wherein the overall length specifications of the gold gourami and blue gourami are 2.8-3.1 cm; in the first ten days of May, stocking Chinese softshell turtle in the turtle pond, wherein the average weight of the Chinese softshell turtle is 140-155 g; in the middle ten days of May, stocking hypostomus plecostomus of which the average total length is 3.0-3.2 cm in the turtle pond, and conducting intercropping till a culture period is finished. According to the water-saving synergy method for intercropping the spectacular fish in the intensified turtle pond, through a mode of intercropping the tropical spectacular fish like the gold gourami, blue gourami and hypostomus plecostomus in the turtle pond, so that the water quality in the turtle pond is improved, the environment is relatively appropriate, the turtle death rate is lowered, and the yield is sharply increased. Moreover, compared with an existing breeding method of the Chinese softshell turtle, the water does not need to be replaced, what is only needed is to add water irregularly into the turtle pond to maintain a breeding water level, thus the water usage amount can be effectively saved, the water usage cost can be lowered, and the economic benefit is increased.

Description

Technical field [0001] The invention relates to the technical field of freshwater aquaculture, in particular to a water-saving and efficiency-enhancing method for cultivating ornamental fish in intensive turtle ponds. Background technique [0002] Chinese soft-shelled turtle is an important economic species for freshwater aquaculture in my country. Intensive greenhouse aquaculture is one of the main breeding methods. Generally monoculture of Chinese soft-shelled turtles is carried out. Pure water fishes such as silver carp, bighead carp or tilapia are not farmed. Pool water A large amount of plankton, organic debris, and humus have no way to use them, and can only be used as fouling factors to deposit at the bottom of the pond or be carried out with water changes. The aquaculture environment is more prone to deterioration than ponds. In addition, the Chinese soft-shelled turtle requires more than 40% of nutrients such as protein, and produces more nitrogen-containing waste. With ...
