Artificial breeding method of sabot blue crab

Abstract

The invention discloses a method for artificial feeding soft shell green crab, which includes self-making glass tank, setting bamboo sheets on the bottom, separating glass tank to several small regions by sheet glass; pooling aquaculture water into the glass tank after it is sterilized thoroughly, keeping the height of water level on 50cm, clear water, 15 per mill salinity, keeping water temperature on 15 DEG C, pH 7.6; selecting green crab which has hulled for 10 times and will be appeared on the market, putting 2 green crabs into small regions of every glass tank; keepin g dissolved oxygen over 5ml / L in the aquaculture water; hulling to soft shell green crab for culturing 5 days. The artificial feeding soft shell green crab of the invention can improve the bottom ecology of the glass tank, favor the survival rate in the process of green crab hulling, decrease occurrence of disease; materials with chemical constituents are not added in the period of culture, green crab has plump meatwithout any toxin and nutrition added valve is higher; the body weight of green crab can increase about 41% after hulling, and keeps the time of soft shell of green crab for 7days.

Description

technical field

[0001] The invention belongs to the field of aquaculture, and in particular relates to a method for artificially cultivating soft-shell mud crabs. Background technique

[0002] Scylla, also known as Scylla serrata, is a benthic crustacean. Because of its tender meat, delicious taste, rich nutrition, and medicinal functions such as clearing away heat, nourishing and disinfecting, it is generally welcomed by people and has high economic value. Every year from March to October in the lunar calendar, blue crabs moult naturally.
