The yield and quality of shrimp seedling kind is all very unstable, and average product is less than 500,000 tails/mu, far can not meet extensive adult freshwater shrimp
The demand of cultivation.Find through our observational studies in recent years, in Macrobrachium nipponensis(de Haan) germling I～III phase, honest Flos Jasmini Nudiflori season, often
Can there is, because of reasons such as unexpected rainstorm weathers, the phenomenon of falling algae, germling cannot get enough bait and high-volume is dead；Meanwhile, also often
Often because of the ciliophoran a large amount of parasitisms of water body set class, so that germling normally can not be shelled and dead；Later stage is also because of some nutrients
It is unsuccessful that not enough and appearance shells, and fishes for rear transportation survival rate very low.Above-mentioned factor directly affects the survival rate of Macrobrachium nipponensis(de Haan) seed and matter
Amount, therefore, Macrobrachium nipponensis(de Haan) seed scale breeding technology not yet breaks through so far, and seed rearing survival rate is low, have impact on into shrimp aquaculture
The cultivation enthusiasm at family.
