Australian blue lobster aquaculture methods include pond selection, aquatic planting, stocking density, bait feeding, water quality management.
1, pond selection
The best choice of pond in the water supply, open ground, slightly sloping terrain. Pond area can be large or small, the depth of water in 0.7-1.5m is appropriate, the water quality requirements of fresh, pollution-free, dissolved oxygen in the water more than 4mg / L, PH value of 7.0-8.0. At the same time, equipped with a good variety of drainage and irrigation and oxygenation equipment.
2, water planting
Along the pond around the shallow water at about 20% -50% area planting of water plants, generally can choose to plant the black leaf rotunda and Ella algae. Take shallow water planting, to be gradually survived water plants and then gradually add water. In addition, the pond water surface can also be a small amount of transplantation of water peanut grass clusters and water hyacinth.
3, stocking density
Shrimp seedling cultivation pond stocking density of no more than 1,000 tails/m2 is appropriate, appropriate dilution and timely sub-nutrient is conducive to improving the survival rate, the general cultivation of the survival rate of up to 50% -70%. Pay attention to do a good job before releasing seedlings to disinfect the pond.
4. Bait feeding
Pre-phase to small mixed fish, scraps of meat and artificial feed is the main; in the middle and late feeding all the rolled snail, mussels and moderate amount of plant feed. Bait placement should follow the principle of timing, pointing, quantitative, generally feeding once a day in the morning and evening.
5. Water quality management
Regularly monitor the water quality, fertilize on time, replenish the beneficial bacteria, and use more calcium-magnesium-phosphorus fertilizer or sodium humate fertilizer. In addition, every 10-15d add water 10-15cm, to ensure water transparency, rainy days splashing lime 3-5mg / L. If a large number of shrimp fry moult, but also need to splash active calcium 3.75-7.5kg / hm2.
