Abstract

The fishing sector produces substantial waste. The primary goal of this work was to obtain organic fertilizers for use in agriculture by composting fish waste. Four waste mixtures were used in the experiment: cow waste only (C), cow waste combined with dried fish waste previously collected (CF) with a mixing ratio of 1:3, poultry waste (P), and poultry waste combined with fish waste (PF) at the same mixing ratio. The fish waste treatments (PF2 and CF2) recorded a much lower pH than the untreated treatments with fish waste. The pH values were neutral values after the maturity of fish waste. The highest N percentage was in poultry with fish, followed by cows mixed with fish, poultry, and cows. Over time, the GI increased in all treatments because of the compost maturity, recording values higher than 75%. The results confirmed the compost suitability in all treatments for agricultural use. R2 values reflect their efficiency in interpreting and predicting the results of GI based on pH, EC, and N. The results showed that the compost physicochemical properties had significant influences on the GI values. The results proved that it is possible to use fish waste mixed with of poultry and cow manure to produce an environmentally safe fertilizer and better than the compost product of poultry and cow manure only
