Effect of different recycled fisheries and domestic waste compost on the production of Spirulina platensis

Abstract

Solid wastes of finfish and shellfish could be converted into bio-manure through composting process and it can be used for protein (Spirulina) production through aquaculture and bioremediation. The study is aimed for Spirulina production from different recycled fisheries and domestic wastes under homestead condition. The different wastes were collected from different sources and were converted into manure by composting process. The Spirulina is produced in five culture treatments fertilized with composts viz., trash fish compost (T-1), cephalopod compost (T-2), crustacean compost (T-3), mangrove compost (T-4) and kitchen waste compost (T-5) and the control without fertilizer compost (C) for sixty days. The population of Spirulina platensis was higher in cephalopod composted tanks (T-2) when compared to the other treatments. The compost made by cephalopod waste, and trash fish waste, may profitably be recycled for the production of protein-rich Spirulina under homestead condition.
