Prof. Boyd writes that his calculations suggest that the efficiency of shrimp pond aeration could be improved with internal combustion engines and drive trains.
Prof. Boyd discusses energy use in aeration for aquaculture production systems, along with rates, types of aerators, motors and electricity generation.
In this second of two parts, the author describes a public-private competitive improvement plan and how technology and new tools improved shrimp production in Ecuador.
Bubble size is a critical parameter in diffused bubble, aquaculture aeration systems. This study was conducted to determine the influence of water with different salinities on performance of nanobubble generating technology (NBT).
The summer season poses threats for oyster aquaculture worldwide. In addition to high mortality, poor oyster quality and health – especially in enclosed bays – are often attributed to water stratification, high temperatures and hypoxia.
While intensive shrimp farms in Australia and elsewhere are sensitive to rising energy prices, global intensification and farming innovations have led to significant improvements in shrimp farm energy efficiency. Important among the changes was the global switch to zero-exchange production
The amount of aeration can be increased as feeding rate increases to conserve energy. Aeration in shrimp ponds usually can be reduced from mid-morning until early evening. Research has demonstrated that considerable energy can be saved by using aerator automation
The potential shrimp aquaculture has for significant improvements in performance through improved genetics and nutrition will not be fully expressed unless appropriate feeding methods are practiced.
Although Bali is primarily a tourist destination, several small family-owned shrimp farms are located here. The Ndaru Luat Setio shrimp farm at Kubu raises specific pathogen-free Litopenaeus vannamei in ponds that apply basic biofloc technology with zero water exchange.
