Embodiment

[0020] A method for grading and optimizing the ammonium nitrogen resistance performance of Penaeus japonicus seedlings of the present invention comprises the following steps:

[0021] (1) Randomly select 30 or more shrimp juveniles from each pool of Penaeus japonicus nursery ponds, and measure the following morphological ratio indicators for each shrimp juvenile to be tested in each pond under a dissecting microscope: Note: frontal sword length / full length C 2 ;Head and breastplate length / full length C 4 ;Second abdominal segment length / total length C 6 ; telomere length / total length C 10 ;Forehead Sword Length / Head Breastplate Length C 13 ;Eye diameter / carapace length C 14 ;Height of carapace / length of carapace C 15 ;Abdominal segment height / first abdominal segment length C 16 ; telson height / telson length C 17 ;

[0022] (2) C measured in step (1) 2 、C 4 、C 6 、C 10 、C 13 、C 14 、C 15 、C 16 and C 17 The corresponding value is substituted into the following ca...

Abstract

Provided is a grading and optimizing method for ammonia nitrogen resistance of marsupenaeus japonicas shrimp seeds. P=(-374237.401C2+60262.529C4-482.009C6-5837.357C10+2728.598C13+161295.154C14+6521.543C15+575.301C16+7363.539C17-15438.198) / (-373239.473C2+59971.405C4-204.015C6-5345.370C10+2773.543C13+160584.988C14+6394.044C15+566.017C16+7468.213C17-15349.352). The method determines and screens out shrimp seeds in good ammonia nitrogen resistance according to the value of P.

Description

technical field [0001] The invention relates to a screening method for high-quality Penaeus japonicus in the aquaculture industry, in particular to a method for classifying and optimizing the ammonia nitrogen resistance performance of Penaeus japonicus seedlings, and belongs to the technical field of shrimp aquatic organisms in agricultural aquaculture. Background technique [0002] Japanese sac shrimp (Marsupenaeus japonicus), also known as Japanese prawn, commonly known as "bamboo shrimp", "flower shrimp", etc., belongs to Arthropoda, Crustacea, Decapod order, and Penaeidae. It is widely distributed in the waters south of the Yangtze River Estuary in my country. Indigenous species are my country's traditional marine cultured shrimp species and important aquatic products for export. Because of its bright body color, delicious meat, high nutritional and economic value, rapid growth, strong stress resistance, and suitable for long-distance dry transportation of live shrimp, si...
