This study evaluated the impact of feeding a commercial diet, top dressed with a commercial probiotic, to Pacific white shrimp in a biofloc-dominated tank system. 

El estudio ilustra el rango de opciones de salinidad para la producción de camarones en sistemas de biofloc a escala comercial, y no encontró diferencias significativas en ninguna métrica de producción de camarón. 

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. 

Se llevó a cabo un estudio de respuesta a la dosis en un sistema biofloc al aire libre para comenzar a cuantificar la función de producción de la densidad de siembra de alevines avanzados de lobina sunshine. 

A dose-response study was conducted in an outdoor biofloc system to begin quantifying the stocking rate production function for sunshine bass advanced fingerlings. 

Un estudio reciente en la Universidad Federal de Rio Grande, Brasil, mostró que es posible reducir la relación C:N en los cultivos de biofloc, para disminuir el volumen de agua utilizada y el total de sólidos suspendidos producidos, con el consiguiente ahorro. 

A recent study at the Federal University of Rio Grande in Brazil showed that it is possible to reduce the C:N ratio in biofloc cultures, to decrease the water volume used and the total suspended solids produced, with resulting savings. 

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. 

The impact of diseases led some Asian shrimp farming countries to develop biofloc and recirculation aquaculture system (RAS) production technologies. Treating incoming water for culture operations and wastewater treatment are biosecurity measures for disease prevention and control. 

En este estudio se compararon dos tipos de sistemas de cultivo de camarón bajo techo: RAS de aguas claras y sistemas de biofloc. El RAS de aguas claras tuvo la ventaja en la calidad del agua, y el camarón en el tratamiento biofloc tuvo una mayor conversión de alimento. 

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

This study compared two types of indoor, shrimp culture systems: clear-water RAS and biofloc systems. Clearwater RAS had the edge in water quality, but shrimp in the biofloc treatment had a higher feed conversion ratio. 

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). 

Larval shrimp performance (feed conversion and final weight) in a biofloc nursery system improved with both added diatoms (Navicula sp.) and rotifers (Brachionus plicatilis). 

This year’s Aquaculture America in San Antonio, Texas, provided significant learning and networking opportunities. It successfully brought together 14 U.S. aquaculture organizations and more than 1,600 participants from Europe, Asia, Africa and Australia.
