Stocking Density & BiomassAquaculture Tech
Calculate stocking density (kg/m³ or L/kg), total biomass, and maximum safe fish count based on tank volume and average fish weight.
Aquatic ecosystems are dynamic biological buffers. Physical parameters like dissolved oxygen levels must be cross-checked with biological and chemical filtration limits to maintain optimum fish welfare.
Exceeding recommended carrying density limits increases ammonia accumulation, physical fin erosion, stress hormone levels, and causes high susceptibility to disease outbreaks.
