breeding varieties: Penaeus vannamei
farming area: two acres of water depth of 1.7 meters
water quality index: pH8.5, ammonia nitrogen 0.2, sub-salt 0.1
Description of the situationThe water color is red, the algae phase is mainly naked dinoflagellate, and a few green algae diatoms.
Treatment SchemeIn the morning, use 2 mu/bag of water to change overlord, 3 mu/bottle of clear water to detoxify and supplement bacteria in the afternoon, use super strong bottom to clean 2 mu/bag to change the bottom in the evening, continue to detoxify and supplement bacteria on the second day, and supplement algae seed and fertilizer on the third day. At the same time, the use of stress nutrients to improve shrimp immunity.
Effect feedbackThe water color changes to yellow-green, the algae phase changes to mainly green algae, with a few diatom cyanobacteria.
Case analysisExcessive reproduction of naked dinoflagellates will inhibit the reproduction of beneficial algae in water bodies; It will lead to hypoxia in the middle and lower water bodies, especially at night, which will consume a large amount of oxygen, resulting in hypoxia in shrimps. When naked dinoflagellates pour algae, a large amount of algal toxins will be produced, resulting in shrimp poisoning or hypoxia, and phenomena such as not eating, floating head, swimming pond, etc. The water-changing overlord can strongly inhibit the excessive reproduction of harmful algae (dinoflagellates, dinoflagellates, and dinoflagellates). Bishui Jiedu An is a polybasic organic acid, which can degrade the algal toxins produced by dinoflagellates. Super bottom net can oxidize and decompose too much organic matter at the bottom to create a good bottom environment. Timely replenishment of bacteria to decompose organic matter in the pond while inhibiting the reproduction of dinoflagellates.
