Green prawns: Spring shrimps and fashion cages are sold for sale. The nursery ponds fertilize the water by fertilizing or pouring soy milk to ensure that there are enough plankton in the shrimps for bait.
Macrobrachium rosenbergii: Do a good job feeding feed, feed the amount of shrimp within the pool of 6% to 8%, and gradually increase the water level, to the end of June to fill.
Penaeus vannamei: rational preparation of the salinity of the holding pool, timely release of shrimp.
Crabs: Oral administration of crab sickness? For 6 consecutive days, add 100 kg/mu of snails and 5 to 7.5 kg of lime in the middle. Spatter photosynthetic bacteria once in the end.
Soft-shelled turtles: enter the strong feeding stage, feed enough food, poor water quality can use photosynthetic bacteria or Bacillus to purify water.
Shrimp pond flower buds: timely release of species of shrimp and snails, check the growth of indole feeding.
Astragalus: Sprinkle photosynthetic bacteria once to improve water quality, and feed quails every evening, accounting for 4% to 5% of body weight of Astragalus.
Bullfrog: Into the hunger period, feed plenty of food.
