Study demonstrated the viability of L. vannamei culture in sandy soils and lined ponds using relatively high shrimp densities, with the best results produced at a stocking density of 100 shrimp per square meter, which produced the best growth and survival
Three years of testing clearly demonstrated that increasing daily feedings through the use of automated feeding systems – a transformational technology – can significantly increase the production and value of L. vannamei produced in semi-intensive pond culture.
A study conducted with juvenile shrimp (Litopenaeus vannamei) reared in experimental biofloc systems used four treatments. Results indicate that differences in management and carbohydrate source can lead to substantial disparity in system function and production.
Honduras-based Grupo Granjas Marinas believes that large-scale production of rotifers and copepods and sequential pond inoculations, in combination with short shrimp growth cycles can significantly increase shrimp production while reducing dependency on other sources of protein in feeds.
In biofloc production systems, ammonia-oxidizing bacteria process ammonia to nitrite, which provides substrate for nitrite-oxidizing bacteria that process nitrite to relatively non-toxic nitrate.
