Measures to improve the survival rate of shrimp seedlings
During the hatchery, the shrimp seedlings always provide shrimp seedlings with highly nutritious shrimp slices and red worms. When they are put into shrimp ponds, we also need to care for the shrimp seedlings like nursing babies to provide various nutrition for the shrimp seedlings to meet The nutrient requirement of the shrimp seedlings is therefore essential for the maintenance of the seedlings.
(a) fertilizer and water algae:
Method one: first use the water purification king or detoxification super cool (1 bottle 3-4 mus) splash, and then press 3-5 with 1 package of enzyme calcium fertilizer +1 barrels of six antibiotic algae paste +1 bag special force calcium and water after mixing Soak for three hours after soaking.
Method two: first use water purification king or detoxification super cool (a bottle of 3-4 acres) splash, and then press 3 acres with algae happiness + diatom ointment / six antibiotic algae paste, add water, mix and splash. (this method is easy to diatomite water)
Method 3: Use water purification king or detoxification super cool (1 bottle of 3-4 mu) to splash first, then use 1 bucket of six antibiotic algae paste/diatomite paste + 1 pack of enzyme calcium fertilizer + 1 pack of special calcium + 1 pack of black gold God added water to soak after a night, available 3-5 acres.
Method 4: Use water purification king or detoxifying super cool (1 bottle of 3-4 mu) to sprinkling, then use 1 bottle of new live bacterium king +1 barrel of six antibiotic algae paste and mix for 3 hours and mix with 2 bags of degradable spirit. Available 3 acres.
(b) One or two days before planting, it is recommended to use Jianmiaobao (1 package of 1 mu) + enzymatic hydrolyzed polysaccharides/Forte (1 package of 2 mu each) to splash water, aiming to cultivate zooplankton (such as the red worms) Zooplankton) feeding shrimp seedlings.
(3) Use nurse seedlings (1 bottle of 2 mu) + enzymolysis polysaccharide (1 packet of 2 mu) or nano oxygen sprinkling two hours in advance on the day of release. After seedling, high-stable C/stress+ ions were used to sputter the calcium (1 bottle 2 mu) + degrading spirit (1 package 2 mu) in order to improve the anti-stress ability and survival rate of the shrimp.
(iv) Seedling management in ten days:
1. Timely and appropriate amount of spilled Jianmiaobao (1 package 1 mu) + enzymolysis polysaccharides / Forte (1 package 2 acres) water spilled, open material and cultivate zooplankton (small red worms) feeding shrimp to meet, to meet Shrimp nutrition requirements;
2. The appropriate amount of protective seedling dew (1 bottle of 2 mu) was poured in water in a timely manner to increase the survival rate of shrimp seedlings;
3. Use ion-pair calcium + degradative spirit + high stability C (1+1+1 with two acres) to meet calcium absorption at seedling stage;
4. Water retention: 1 bottle of new live bacteria king +1 barrels of six antibiotic algae (algae happiness, algae health, diatomaceous algae), add water, mix and splash, 5-6 acres available.
