Urgent appeal to control spread of the shrimp microsporidian

Enterocytozoon hepatopenaei (EHP) is a microsporidian parasite that was first characterized and named from the giant or black tiger shrimp Penaeus monodon

Analyzing the hydrostability of shrimp feeds

Aquafeeds can lose nutrients rapidly after immersion, so it is important that feeds have adequate stability and attractability after immersion in water

Rotifers and diatoms aid shrimp biofloc nurseries

In shrimp farming systems, the microbial community plays an important role in recycling nutrients, decreasing the anoxic zones in ponds

The complex principles of redox measurement

During the past few years, several aquaculturists have asked me about the use and significance of the oxidation-reduction potential – often referred to as ORP

The importance of water analysis in aquaculture

Water analysis is becoming common in production aquaculture. At many production facilities, managers measure a variety of water quality variables

Calcium and magnesium use in aquaculture

Concentrations of calcium and magnesium are seldom measured in waters for aquaculture, but total hardness is determined rather often.

Understanding the oxygen demand of aquafeeds

Feed allows a great increase in the amount of aquaculture production possible in a given volume of water. But feed also results in an oxygen demand

Artemia, the ‘magic powder’ fueling a multi-billion-dollar industry

Hatcheries depend on the brine shrimp artemia – microscopic creatures facing climate change and overharvesting threats – as feed in larviculture

Culture of giant freshwater prawns in China

The giant freshwater prawn (Macrobrachium rosenbergii) is one of the most commercially cultured crustaceans in the world.

Building a better shrimp nursery, part 1

Shrimp nursery systems are valuable production tools. Properly designed and implemented, they are high-biosecurity facilities to grow postlarvae (PL) at high
