Embodiment 1

[0025] 500 Macrobrachium rosenbergii were captured at the breeding farm of Macrobrachium rosenbergii of Guangxi Fisheries Research Institute as samples, and the sample content covered individuals of different growth types of Macrobrachium rosenbergii. Such as figure 1 As shown, each measurement point was located on the shrimp and numbered, and the numbers were sequentially numbered on the telson AB, tail belly BC, cephalothorax CD, and frontal spine DE. Macrobrachium rosenbergii types larger than 20g / tail, numbered at the second abdominal segment FG.

[0026] The samples were divided into 13 types according to different body lengths or weights, and the types are classified in Table 2 below.

[0028]

[0029]

[0030] Measure the AB, BC, CD, DE, and FG values ​​of samples of each type, and divide each value by the number of samples (tail), to obtain the average value of AB, BC, CD, DE, and FG of samples of this type. Then cal...

Abstract

The invention discloses a character identification method for macrobrachium rosenbergii. The method comprises the steps that measuring points are positioned on macrobrachium rosenbergii samples; the samples are classified according to different body lengths and weights; measured values of the samples of the types are measured; an average is worked out; a ratio of the measured values to measured telson data is calculated; a correlation proportion average is obtained; correlation proportion averages of measured data for the types of samples and all the types of samples are subjected to contrastive analysis; and technical operation of macrobrachium rosenbergii germplasm selection is accomplished according to an analysis result. According to the character identification method, the ratio of measuring results of all the type samples to the telson correspondingly varies with different growth types of the macrobrachium rosenbergii, and the value change for a special colony has a relatively obvious difference. Therefore, the character identification method can be applied for selecting and remaining different macrobrachium rosenbergii individuals, special individuals can be found as early as possible, and a success rate of good variety breeding of the macrobrachium rosenbergii is increased.

Description

technical field [0001] The invention belongs to the technical field of aquaculture, and in particular relates to a character identification method of Macrobrachium rosenbergii. Background technique [0002] According to the "Freshwater Shrimp-Macrobrachium rosenbergii Farming Manual" in the FAO Common Document Library of the United Nations Food and Agriculture Organization, Macrobrachium rosenbergii was transferred from its original habitat to other parts of the world, initially for research purposes, and later as a commercially farmed species. country imports. Following the introduction of the breed from Malaysia to Hawaii in 1965, the pioneering work of Ling (1969) there was developed by Fujimura and Okamoto (1972) into a method of large-scale PL production that was adopted on nearly every continent . Major producers of Macrobrachium rosenbergii are now Bangladesh, Brazil, China, Ecuador, India, Malaysia, Taiwan Province of China and Thailand (FAO 2002). According to re...
