However, shrimp seedlings cultivated in fresh water can only grow in fresh water environment. When metapenaeus ensis is cultured, it can be provided with fish meal and animal offal with high protein content, and it can also be provided with cereal feed for metapenaeus ensis to make it grow more robust.
When breeding metapenaeus ensis, it is necessary to select high-quality shrimp seedlings. First of all, we need to look at the appearance of shrimp seedlings, choose shrimp seedlings that are not damaged for breeding, and also need to look at the size of shrimp seedlings. It is best to choose shrimp seedlings with similar size for breeding, so as to avoid the phenomenon of struggle between shrimp seedlings in the process of breeding.
When metapenaeus ensis is cultivated, it can be provided with foods with high protein content, such as earthworm, breadworm and animal viscera, so as to improve the growth speed of metapenaeus ensis, and it can also be provided with cereals such as rice bran and wheat bran, so as to provide energy for metapenaeus ensis. When feeding, it is best to make the feed into balls, which is convenient for metapenaeus ensis to eat.
Introduction to metapenaeus ensis's Living Habits
Metapenaeus ensis (Macrobrachium nipponense) is a kind of shrimp with wide temperature and salinity. It lives in the estuary and inner bay area with low salinity in its larval stage, and then moves to the water area with high salinity (mostly concentrated in the water area of 20-30m) with the continuous growth of metapenaeus ensis. The suitable water temperature is about 22-33℃, and the salinity adaptation range is between 0-34%.
The suffocation point in metapenaeus ensis is below 0.6mg/L, and the Gan Lu time (which refers to the time that mariculture is exposed to the air at low tide or other reasons) varies with the temperature and humidity. When the temperature is 25℃ and the humidity is about 80-90%, the Gan Lu time exceeds 10 hour.
