Abstract

The study aimed to determine the optimal substrate for L. hoffmeisteri culture in artificial conditions. The experimental period consisted of 4 treatments (T) randomly designed and replicated 4 times. It included T1 (control): 100% sludge; T2: 50% sludge + 50% chicken manure; T3: 50% sludge + 50% cow dung; and T4: 50% sludge + 25% cow dung + 25% chicken manure. The obtained results showed that L. hoffmeisteri biomass gained between 45.4 - 367g/m2; the highest biomass was found in T2 of 367 ± 39.9 g/m2, while the lowest was recorded in T1. The population density ranged between 53,900 – 87,125/m2; the highest density was found in the T4 of 87,125 ± 14,766/m2 and the lowest one in T2. Thus, it shows that 50% sludge + 50% chicken manure is the optimal substrate for raising bloodworms.
