Un estudio determinó el rendimiento zootécnico del camarón blanco del Pacífico bajo diferentes regímenes de luz. Los camarones expuestos a la luz tienen mejores parámetros zootécnicos que aquellos con exposición reducida o nula. 

Los resultados de este estudio muestran que los sistemas de alimentación automatizados son significativamente más eficientes que la alimentación manual en estanques de producción de camarón, y que los aumentos en los aportes de alimento, la aplicación de tecnología adaptativa y la capacitación de las personas para mantener el sistema de alimentación deben considerarse al implementar nuevas tecnologías. 

Study illustrates the range of salinity options for shrimp production in commercial-scale biofloc systems and found no significant differences in any shrimp production metric. 

A study determined the zootechnical performance of Pacific white shrimp under different light regimes. Shrimp exposed to light had better zootechnical parameters than those with reduced or no exposure. 

Results of this study show that automated feeding systems are significantly more efficient than hand feeding in shrimp production ponds and that increases in feed input, application of adaptive technology and training of people to maintain the feeding system must all be considered. 

In this feeding study with Pacific white shrimp juveniles cultured at very high density in a closed system, results showed that continuous feeding with a high protein diet is less practical than feeding the shrimp with a low protein diet and under mixed feeding schedules. 

This study evaluated the relationship between the molting stage, age and osmotic stress in Pacific white shrimp postlarvae. The results indicate that osmotic stress tests should be done only with at least PL12 at the intermolt stage and that were cultured at 35 ppt salinity and 29 degrees-C. 

Los alimentos acuícolas para camarón – vivos, frescos o formulados – no deben ser un punto de entrada de patógenos potenciales para el camarón y/o sus sistemas de cultivo. 

Research from experimental trials demonstrate that dietary potassium diformate improves survival, growth and productivity in Pacific white shrimp (Litopenaeus vannamei), including in the presence of the Gram-negative, pathogenic bacterium V. harveyi. 

El cultivo del camarón tierra adentro tiene numerosas ventajas – mejora la bioseguridad, el costo más bajo de la tierra, y reduce los conflictos con otros usuarios de recursos comunes como la tierra y el agua – y seguirá expandiéndose hacia nuevas áreas. 

Shrimp aquafeeds – live, fresh or formulated – should not be an entry point of potential pathogens to the shrimp and/or to their culture systems. 

Inland shrimp culture has numerous advantages – improved biosecurity, lower cost of land and reduced conflicts with other users of common resources like land and water – and will continue to expand into new areas. 

A study compared the bioavailability of crude protein and lipid from biofloc meals generated with an activated sludge system using two water sources: wastewater from shrimp experimental culture (BFL-W) and, artificially, using clean seawater (BFL-C). 

Accurate PCR testing of shrimp seedstock assures shrimp farmers that their seedstock is clean of major diseases. Ring tests verify that labs conducting PCR testing are obtaining correct, reliable and reproducible results when testing for specific shrimp diseases. 

Este estudio evaluó cinco dietas formuladas con niveles crecientes de metionina (Met) y Met + cisteína (Cys) y sus efectos sobre el crecimiento de juveniles de camarones blancos del Pacífico sembrados a 50, 75 o 100 animales/m2 en un sistema de agua verde.
