Cladoceran Moina micrura is an important live food organism in aquaculture. It provides essential nutrients such as proteins, lipids, and amino acids for fish and crustacean larvae. The composition of their diet primarily influences their growth and reproduction. The spent mushroom substrate (SMS), mushroom stalk waste (MSW), and mushroom fruiting body (MFB) have the potential to serve as an alternative food source due to their nutrient content. However, their efficiency in supporting M. micrura production remains unclear. Therefore, this study aimed to evaluate the effects of Pleurotus florida mushroom byproducts on the life history and population dynamics of M. micrura. A controlled experiment was conducted using different diets provided at 1000, 500, and 250 mg/L concentrations. The positive control was provided with baker’s yeast, while the negative control was provided with tap water without feed. Selected life history variables were measured to assess the production performance. The results showed that M. micrura fed 1000, 500, and 250 mg/L of SMS, as well as 500 mg/L of MSW and MFB, exhibited better production and longevity. The findings suggest that SMS and MSW have the potential to be alternative food sources in M. micrura production. Moreover, the high cost of MFB makes it less practical for large-scale use.
