Circular tanks are widely used in aquaculture due to their efficient and flexible hydraulic control , optimal water quality and fish welfare, and adaptability to various additional features . Several key components of the culture tank work together to maximize productivity, reduce labor costs, and ensure fish health . This presentation will cover the general material and geometrical requirements of a properly designed circular fish culture tank and the integration of other key features that are critical to the successful operation of the tank and the system.
Circular tanks naturally facilitate the collection of solids in the center due to their continuous water flow patterns. Proper t ank hydraulics are key to ensuring solids are quickly removed from the tank and delivered to the removal treatment process. Mortalities removal is a critical feature of circular tanks, as it helps maintain water quality and prevents disease outbreaks. These systems are often integrated with sensors that detect mortalities , enabling the system to remove them without human intervention.
Efficient and controlled feeding is essential for maximizing growth and reducing waste. Integrated a utomatic feeders can be programmed to dispense precise amounts of feed at specific intervals. Feed optimization is enhanced with integrated sensors that monitor water quality and feeding activity and adjust feed quantities based on the fish’s consumption and metabolic needs.
Tank lighting systems are commonly used in aquaculture tanks to simulate natural daylight cycles, which can promote optimal growth and reduce stress in fish. Lighting can be adjusted in intensity and wavelength to match specific species’ requirements or stimulate breeding. Proper lighting can also help guide fish during feeding and prevent stress caused by excessive or insufficient light exposure.
Modern aquaculture systems rely heavily on sensors for real-time monitoring of tank conditions to ensure the health of the fish and the efficiency of operations. These sensors can trigger automated systems, such as Oxygen diffusers or pumps, to adjust water conditions in real-time. Fish behavior sensors use cameras and algorithms to track fish movement, feeding habits, general health and total biomass . This data helps operators make informed decisions regarding feeding, water quality adjustments, or other interventions.
The integration of advanced technologies such as automated feeding, real-time sensors, mort removal, and video monitoring into circular tank designs significantly enhances the efficiency and sustainability of aquaculture operations.
