Feed Conversion Ratio (FCR)Aquaculture Tech
Determine feed efficiency (FCR), specific growth rate, and economic cost per kg of fish biomass gain.
Calculates aggregate farm biomass increase compared with aggregate dry feed inputs.
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.
Extremely efficient nutrient conversion. Typical of optimized salmonid setups or very young fry.
