Embodiment 1
[0026] In October 2020, 40 heterotrophic silver crucian carp cultivated products were randomly selected for each of the three breeding modes: the pond monoculture model (M1), the pond polyculture model of Penaeus vannamei (M2) and the reservoir stocking model (M3), totaling 120 fish. , to measure the morphological index. The measuring tools are: electronic digital vernier caliper with an accuracy of 0.01 mm (Guilin Guanglu Digital Measurement and Control Co., Ltd.), an electronic scale with an accuracy of 10 g (Ningbo Huasheng Technology Co., Ltd.), and a Sartorius BS223S electronic balance with an accuracy of 0.01 g (Sartorius Scientific Instrument (Beijing) Co., Ltd.).
[0027]1. M1 breeding mode Silver crucian carp summer flower seedlings are planted into the pond, the breeding time is 2 years, the stocking density is about 2500 catties / mu, and the special feed for crucian carp is fed during the period; M2 summer flower fingerlings are cultured in the pond for 1.5 years, an...
Embodiment 2
[0041] In August 2021, 20 cultivars of heterotrophic silver crucian carp were randomly selected for each of the three breeding modes: the pond monoculture mode (M1), the pond polyculture mode of Penaeus vannamei (M2) and the reservoir stocking mode (M3), totaling 60 animals. , to measure the morphological index. The measuring tools are: electronic digital vernier caliper with an accuracy of 0.01 mm (Guilin Guanglu Digital Measurement and Control Co., Ltd.), an electronic scale with an accuracy of 10 g (Ningbo Huasheng Technology Co., Ltd.), and a Sartorius BS223S electronic balance with an accuracy of 0.01 g (Sartorius Scientific Instrument (Beijing) Co., Ltd.).
[0042] 1. In M1 breeding mode, silver crucian carp fry are planted in the pond, the breeding time is 1.5 years, and the stocking density is about 3,000 jin / mu. During this period, the special feed for crucian carp is fed; M2 summer fry are cultivated in the pond for 1 year, and the stocking density is It is 300 jin / ...
