How to manage Hydrogen Sulfide in shrimp ponds

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 oxygen levels and create a stream of water with additional oxygen. Across the interface between land and water, liming to…

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 organisms such as frog eggs, tadpoles, insects, snails, green moss and soft-bodied grasses, some kinds of fish such as perch…

Using Ozone (O3) for water treatment in shrimp ponds

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 oxygen. O3 in water reacts with water immediately, the higher the pH (salty and brackish water), the greater is the…

Shrimp pond – Location selection and how to construction

Choosing a pond construction site is a very important issue that has a great impact on the investment, construction and risk in the future. 1. Location – The area is water-free, with an easily accessible drainage system, with saltwater source (if there is fresh water source). – Have good grid power, good traffic and good security, near to the shrimp farming. 2. Terrain, geology – Shrimp ponds should be built in high tide areas. –…

How to alkalinity management and water hardness in shrimp ponds.

How to alkalinity management and water hardness in shrimp ponds.

In this article, we would like to share with you the problems of alkalinity management and water hardness in shrimp ponds. 1. Alkalinity– Alkalinity is the ability to buffer the pH of water. The amount of base present in water is the total alkalinity. Common bases in aquaculture ponds are Carbonate, Bicarbonate, Hydroxyte, Phosphates and Berates. Carbonate (CO32-) and Bicarbonate (HCO3-) are the two most common bases and major constituents of alkali. Total alkalinity is…

Method of water coloring in shrimp ponds

Method of water coloring in shrimp ponds

After preparing ponds and water coloring, this is aimed at developing phytoplankton to stabilize water color and create a favorable environment for shrimp to develop rapidly, increasing survival rate. Some effective coloring methods are as follows: 1. Method 1: According to formula 2: 1: 2 (2 kg rice bran or maize bran + 1 kg fish meal + 2 kg soybean meal). Mix the mixture well then cooked, cover for 2 – 3 days. Use…

Shrimp and its activity in ponds

Until the shrimps gain weight of 5g or more, the activity of shrimp in ponds is quite similar in species. Therefore, within the scope of this article, we have generally commented on all shrimp species. 1. Overview of shrimp farming– As a child, shrimp undergo many changes in behavior and physiology. But when they reach the size of 2 – 5 g / head, they begin to swim and behave like adult shrimp. Most of…
