Takifugu rubripes gastrointestinal emptying parameter evaluation method

Abstract

The invention discloses a method for evaluating gastrointestinal emptying parameters of fugu rubripes, and relates to the technical field of aquaculture, and the method comprises the following steps: a1, selecting experimental fishes: randomly selecting 3000 healthy and injury-free large-specification fugu rubripes fries, and carrying out detailed evaluation on the gastrointestinal emptying mode of the fugu rubripes fries by setting a comprehensive evaluation method; gastrointestinal emptying mode research of different feeding frequencies under the condition of a small circulating water system is carried out, and an optimal mathematical model conforming to the gastrointestinal emptying characteristics of the takifugu rubripes large-scale offspring seeds is established, so that the problem that research data about the gastrointestinal emptying mode of the takifugu rubripes, especially in the large-scale offspring seed stage, is not reported yet nowadays is solved. The problems that effective parameters cannot be provided for fugu rubripes culturists, certain troubles are brought to the corresponding fugu rubripes culturists to formulate feeding strategies, and great difficulty is brought to early-stage breeding of large-size fries of fugu rubripes are solved.

Description

technical field [0001] The invention relates to an evaluation method for aquaculture, in particular to a method for evaluating gastrointestinal emptying parameters of pufferfish. Background technique [0002] Pufferfish is an important seawater cultured fish in China. It is a bottom fish in the warm temperate zone and tropical offshore. Its meat is delicious and nutritious, and it is a valuable economic fish species. , the breeding scale is increasing, the breeding methods are diversified, and the breeding output is increasing year by year. The annual output of finished fish in the country is about 8,000 tons, with an output value of 600 million yuan. It has formed a large scale and has significant economic and social benefits. At present, the red The main breeding mode of puffer is industrial recirculating aquaculture. In the intensive aquaculture environment represented by industrial recirculating aquaculture, most of the nutrition and energy of aquaculture animals come fr...

Problems solved by technology

[0003] The purpose of the present invention is to provide a method for evaluating the gastrointestinal emptying parameters of the red fin puffer, to solve the current research data on the red fin puffer, especially the gastrointestinal emptying pattern of the large-scale seed stage, proposed in the above-mentioned background technology It has not been reported yet, and thus cannot provide effective parameters for redfin puffer breeders, and then brings certain troubles to the corresponding red fin puffer breeders in formulating feeding strategies, thus giving red fin puffer large-scale seed Early breeding poses extremely difficult problems
