Embodiment Construction

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

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

[0034] The present invention provides a water-saving and efficiency-enhancing method for intensive turtle pond breeding of ornamental fish, comprising the following steps:

[0035] Carry out pretreatment to turtle pond before stocking in a suitable place and dry water;

[0036] In late April, stock yellow mandarin fish and blue mandarin fish with a full length of 2.8-3cm in the turtle pond, and the total stocking density of yellow mandarin fish and blue mandarin fish is no more than 10 fish / m 2 ;

[0037] In the first ten days of May, stock soft-shelled turtles with an average body weigh...

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 nesting ornamental fish in intensive soft-shelled turtle ponds. Background technique [0002] Chinese soft-shelled turtle is an important economic species of freshwater aquaculture in my country. Intensive greenhouse aquaculture is one of the main breeding methods. Generally, Chinese soft-shelled turtle is raised alone, and silver carp, bighead carp or tilapia and other clean water fish are not raised together. A large number of plankton, organic debris, and humus in the pond have no way to be used, and can only be deposited on the bottom of the pond as a pollution factor or brought out with water changes. Compared with ponds, the aquaculture environment is more likely to deteriorate. In addition, the Chinese soft-shelled turtle has a nutritional requirement of more than 40% such as protein, and produces more nitrog...
