Dry artificial diets for shrimp offer reliable supply, reproducible and controlled quality, ease of use and improved stability under storage.
The culture of tropical freshwater fishes has led aquaculture development in Brazil, where many areas have the required characteristics to grow the industry.
Researchers at the Oceanic Institute studied the effects of pond water on the biology of Pacific white shrimp (Litopenaeus vannamei).
In high-density systems with zero water exchange, pond ecology shifts from an autotrophic, phytoplankton-based microbial community to a heterotrophic, bacterial-based community.
Information on catfish nutrition was practically nonexistent in the late 1950s and early 1960s when catfish farming first started.
Shrimp are the most commercially important aquaculture animals that utilize a significant amount of microorganisms in their diet.
Bacteria play a role in the dynamics of nutrients in aquaculture production systems. This article explores the role of bacteria on nitrogen.
Vitamin E, or alpha-tocopherol, is crucial to fish defense against lipid-oxidising free radicals. It also has great impact on flesh quality.
Penaeid shrimp require dietary vitamin C for maximum growth and survival. In the 1970s, a vitamin C deficiency disease was described.
Activated suspension ponds are effective at nitrogen control and protein recycling, functioning as a biofilter and as a microbial recycling system.
