Simple Settling Chambers Aid Solids Management In Biofloc System

摘要

A study that examined the effects of removing suspended solids using side-stream settling chambers in a superintensive biofloc shrimp system found the chambers reduced nitrate-nitrogen and phosphate concentrations over 60% and improved shrimp growth rate and biomass by 40%. In comparing a fishmeal-based diet to a plant-based diet used in the system, few differences were noted in terms of shrimp production or water quality.
