Intensive nursery, pre-grow-out of white shrimp in autotrophic, heterotrophic systems
A seven-week trial evaluates autotrophic and heterotrophic systems in the nursery and pre-grow-out of Pacific white shrimp.

What makes bioflocs great for shrimp?
Single-celled proteins in bioflocs can provide protein and other nutrients in shrimp feed, but what makes them enhance growth performance in shrimp?

Malaysia shrimp farm redesign successfully combines biosecurity, biofloc technology
Blue Archipelago’s re-engineering of a large shrimp farm to a modular, biosecure facility set a benchmark for future shrimp culture projects in Malaysia.

Intensive Peruvian operation produces shrimp in greenhouses
Langostinera Florida is an intensive shrimp farm with controlled conditions. Greenhouses can operate in areas where diseases have affected the industry.

New Bacillus probiotic tested for shrimp
The authors evaluated Bacillus bacteria in a pink shrimp nursery and found it controlled Vibrio concentrations as well as a commercial probiotic.

Post-harvest quality of freshwater prawns, part 2
Freshwater shrimp can contain pathogenic bacteria that cause illness unless care is exercised by producers, retailers and consumers. Many of the human pathogens can survive frozen storage, but are killed or inactivated by thermal processes.

Inbreeding affects growth, survival, reproduction of Pacific white shrimp
The Maricultura del Pacífico hatchery in Mexico uses two-stage selection that controls the pedigree of every animal to minimize inbreeding.
Intelligence
Post-harvest quality of freshwater prawns, part 1
Spoilage in freshwater prawns is endogenous rather than exogenous and results from proteolytic enzymes in the cephalothorax.

Shrimp breeding for resistance to Taura Syndrome Virus
In response to Taura Syndrome Virus outbreaks, the U.S. Marine Shrimp Farming Program initiated a selective-breeding program to improve resistance in Pacific white shrimp.

Nitrifying biofilms critical for water quality in intensive shrimp RAS
Nitrifying bacteria readily form biofilms on surfaces, and colonization by these important bacteria on the interior walls of RAS production units likely provides an additional source of nitrification.

Plant, poultry byproduct proteins tested in shrimp diets
A study examined the replacement of poultry byproduct meal with plant proteins and low levels of squid meal in shrimp feeds. Production results for shrimp raised in ponds showed no significant difference in final weight, yield, FCR and survival among the four treatments with varied levels of poultry meal.

Brazil’s intensive shrimp nursery systems improve PL management, grow-out ponds
Intensive nursery systems are an extension of hatcheries to acclimate postlarvae to farm conditions and assess quality and health prior to pond stocking.

Panama demo shows botanical extracts improve shrimp productivity
Maintaining a favorable gut microflora in shrimp can help minimize the impacts of diseases and maximize digestive efficiency. Phytobiotic feed additives modulate microflora in shrimp toward a composition that favors beneficial bacteria and inhibits pathogenic microorganisms.

Research validates forecast declines in shrimp fishmeal, fish oil requirements
The required level of fishmeal in white shrimp diets can be reduced to 5 percent through substitution as long as fish oil content is kept at 2 percent.

Within-family selection enhances shrimp growth
A study in Brazil found that the growth superiority brought about by within-family selection of tested shrimp transmitted to the next generation of animals.

Methionine hydroxy analog supplements low-fishmeal shrimp diets
In a study, the authors evaluated the performance of juvenile white shrimp grown at high density and fed diets with varying levels of methionine. Trends toward improvements in feed intake were observed for diets with reduced fishmeal and HMTBa supplementation.
