Prof. Boyd on dissolved and suspended solids in aquaculture production systems and their importance to water and pond-bottom quality.
The use of biofloc systems for shrimp culture requires monitoring of water quality parameters, particularly suspended solids levels.
Shrimp survival, weight, yield and feed conversion were better in farm units that operated with settling chambers for solids removal than in units without.
To design a settling basin, know the size distribution of particles, estimated rate of inflow and determination of the smallest particle size to be removed.
Authors found the biofilter unit portion of the Intensive Bioproduction Korean system originally developed for nitrification can remove suspended solids.
