Eating behavior and Molting of Black Tiger Prawn

In this article we will give you a detailed explanation of the characteristics of eating and culling of black tiger shrimp. This is an important feature that you need to master the process of shrimp farming

Eating behavior

Black Tiger Prawn is omnivorous. Black Tiger Prawns prefer animals that live and move more slowly than organic rotting or debris. Black Tiger Prawn is particularly favored for crustaceans, underwater plants, organic debris, polychaetes, bivalves, and bivalves.
In the wild, 85% of Black Tiger Prawn’s diet is crustaceans, small crabs, bivalves; 15% are fish, polychaetes, aquatic organisms, organic debris, muddy sand.
In the wild, Black Tiger Prawn catches more prey when the tide recedes.
In the pond, Black Tiger Prawn catches much prey in the early morning and late afternoon.
Shrimp feeds on the bait, then pushes the food into the mouth to gnaw, the digestive period of shrimp feed in the stomach is 4-5 hours.

The Molting

During growth, when the weight and size increase to a certain extent, the shrimp must peel off the old crust to grow.
Stripping often occurs at night. Expression often goes hand in hand with weight gain. However, there are cases of molasses but not weight increase.
When observing shrimps in the tank, molting occurs as follows: The epidermis between the thoracic and abdominal joints is cracked, the anterior part of the chest is drawn first, followed by the abdomen and lateral portions. After, pull out of the hard shell, bending your body.
The new soft shell will harden after 1-2 hours with small shrimp, 1-2 days for large shrimp.
After shedding, the shell is soft and sensitive to the changing habitat. In the process of rearing, it is necessary to adjust the breeding environment in time to avoid shrimps become weak, infected when peeled. When the shrimps are weak, the shrimp are not stripped.
Hormones restrict the molting (MIH, molt – inhibiting hormone) secreted by the cells in the organ of the stalk, transmitted along the sinus axon, which accumulates and transfers into the bloodstream, for control. Shredding of shrimp. Elements of light, temperature, salinity outside will affect shrimp when shrimp shed.
