Filtration Systems in Fishery Aquaculture

Urban Farm DB summary

This literature-based, qualitative content-analysis study examined filtration systems used to maintain water quality in small-scale aquaculture ("urban farming" aimed at self-sufficient food security), covering mechanical media (cotton, dacron), biological media (bio balls, ceramic rings) and chemical media (activated carbon, zeolite). It found that the type of filter media used affects water quality, fish growth and survival, and that using vegetables as supplementary filtration also affected water quality.
