Aerator energy use in shrimp farming and means for improvement

Claude E. Boyd et al.

Summary: The text highlights the range of aeration energy use in shrimp farming and opportunities for reducing energy consumption, such as maximizing aeration capacity, adjusting aeration duration, and monitoring dissolved oxygen concentration. It also suggests replacing inefficient farm-made aerators with factory-made ones and redesigning aerators for improved efficiency.

Resource sharing and resource sparing, understanding the role of production intensity and farm practices in resource use in shrimp aquaculture

Robert P. Davis et al.

Summary: Aquaculture production is a significant part of global food supply, with recent studies suggesting that intensifying shrimp aquaculture could save resources on a per tonne basis. By analyzing production parameters such as feed type and water exchange rate, the study found that land and water use have an asymptotic relationship with production intensity, with water exchange rate being the most important factor in water use and production intensity in land use. Energy use was highest with diets containing fish meal as a protein source, indicating the potential for resource savings with increased production intensities.
