Asepsis key to prevent contamination in shrimp hatcheries

Maintaining biosecurity and asepsis in larval shrimp production is a key component of the production chain in Ecuador, which requires the production of 5.5 billion larvae monthly from 300-plus hatcheries.

Genetics key to maximum growth rate for shrimp

Realizing higher growth rates in commercially cultured shrimp has many important benefits, including reducing various risks, cutting costs and increasing economic opportunities. Shrimp genetics primarily determines the amount of additional growth that can be achieved, as shrimp typically reflect their

Acclimating shrimp postlarvae before pond stocking

Shrimp postlarvae acclimation before stocking into the various growout systems (ponds, raceways, tanks) is a critical – and often overlooked, sometimes taken for granted – step in the shrimp culture process. Various water quality parameters should be changed slowly so

Testing an intensive shrimp hatchery system using biofloc technology

The use of biofloc technology (BFT) is increasing in the commercial production of several important aquatic species, as it can increase production and efficiency and minimize the potential impacts of effluents. This study showed that BFT systems without water exchange

Low-salinity culture water controls Vibrios in shrimp postlarvae

In a survey of Vibrio concentrations in white shrimp postlarvae at two inland farms, hatchery postlarvae were acclimated in water with salinity reduced from 30 and 5 ppt to 2 ppt at the farms. One farm stocked postlarvae in nursery

What size are your postlarvae?

Although the characteristics of shrimp postlarvae have changed over time, the standard method used to identify their size has not. Usually, the “size” of postlarvae is considered their chronological age after completing metamorphosis.
