How to manage Hydrogen Sulfide in shrimp ponds

  Hydrogen sulfide (H2S), which can form in pond bottom sediment, is toxic to aquatic animals because it interferes with the cytochrome a3’s reabsorption during respiration. The main practices to minimize the risk of toxicity of hydrogen sulfide are careful feeding to avoid wasted wastewater at the bottom of ponds, aeration to avoid low dissolved […]

How to control Ammonia in Black Tiger Prawn’s ponds (Part 1)

Ammonia is a toxic substance that is accumulated during the culture process. In properly managed ponds, ammonia rarely builds up to dangerous concentrations. However, ammonia can create so-called “lethal effects”, such as reduced growth, poor food metabolism and reduced immunity in low concentrations. 1. The effect of pH and temperature on ammonia – Ammonia in […]

Using Ozone (O3) for water treatment in shrimp ponds

Ozone (O3) is a strong oxidant, often unstable, easily decomposed into oxygen. In aquaculture, O3 is used for disinfection, reducing turbidity, reducing pesticides and limiting water pollution, helping shrimp and fish grow well.O3 essenceIn nature, O3 is created when there is thunder, in the O3 industry is formed by discharging in normal air or pure […]

The effect of lime on filtering the effect of lime shrimp filtering ponds

According to aquaculture experts, the loading of lime into ponds – lagoons has many effects: to make pond mud have a loose texture, improve the air condition at the bottom, and accelerate the resolution process. organic matter in ponds, releasing N, P, K in mud, increasing nutrition; keep the pH stable. Lime directly kills harmful […]
