Vitamin C (VC) is a common anti-stress product that is used in fish farming. It is widely used during weather changes, water quality changes, water exchange, and before or after stocking. 

The earlier article explained the process of species combination, the level of stocking density and the dissolved oxygen management. We are still discussing three main themes of scientific feeding, partial harvesting and restocking and daily management now.

In the previous article, we discussed the key factors and conditions for high-yield aquaculture. Today, we will focus on practical farming methods.

For a qualified fish farmer, mastering high-yield aquaculture techniques is essential. Key concerns commonly shared among fish farmers include the maximum stocking density of fish and shrimp in ponds, the ultimate yield, and methods to sustain high productivity.

It is well known that products such as calcium chloride and magnesium chloride are widely used in the aquaculture industry, but what important roles do calcium and magnesium play in aquaculture? Today, we will talk about the significance of calcium and magnesium ions in aquaculture!

Enteritis is one of the most common bacterial diseases in Litopenaeus vannamei (Pacific white shrimp). It leads to slow growth, malnutrition, molting difficulties, weakness, and reduced disease resistance. In severe cases, it may cause sudden mass mortality (“sudden death syndrome”). Enteritis also deteriorates water quality, making the pond water sticky, foul-smelling, and prone to secondary problems such as muscle opacity and red body disease.

Maintaining water quality in shrimp ponds requires more than just introducing beneficial microbes; it also demands supplying the nutrients necessary for these microorganisms to flourish. This is precisely the role that carbon sources are designed to fulfill.

Enterocytozoon hepatopenaei (EHP) is a microsporidian parasite that infects the hepatopancreatic epithelial cells of the Pacific white shrimp (Litopenaeus vannamei). This parasite is commonly referred to as the “hepatopancreatic microsporidian” or simply “EHP.” Because it primarily damages the shrimp’s hepatopancreas (liver–pancreas), the disease it causes is widely known as hepatopancreatic microsporidiosis.

Shrimp affected by WFS show slow feeding, stunted growth, and high feed conversion ratios. If not treated in time, the shrimp quickly develop empty stomachs and intestines, emaciation, severe cases of atrophy, and even sudden death, directly impacting farming profitability.
