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
The role of selective breeding and biosecurity in the prevention of disease About 3.5 million metric tons of farmed shrimp were produced globally in 2009 with an estimated value greater than USD$14.6 billion.
Historic Emergence, Impact and Current Status of Shrimp Pathogens in Asia It is estimated that approximately 60% of disease losses in shrimp aquaculture have been caused by viral pathogens and 20% by bacterial pathogens.

The microsporidian Enterocytozoon hepatopenaei is not the cause of white feces syndrome The microsporidian Enterocytozoon hepatopenaei is not the cause of white feces syndrome in whiteleg shrimp Penaeus (Litopenaeus) vannamei
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
Culture of Penaeus vannamei in Single-Phase & Three-Phase Recirculating Aquaculture Systems In recent years, researchers in the U.S. have been working to develop indoor recirculating aquaculture systems for production of marine shrimp
