In larviculture, rotifers are crucial as an initial food source for fish larvae, but their size and density must be managed properly to prevent mortality and developmental issues.
The study applied carbon and argon heavy-ion-beam irradiation to create rotifer mutants with larger sizes, assessing factors like lethality and growth rates.
Three promising rotifer mutants, TYC78, TYC176, and TYA41, demonstrated larger sizes and active population growth, indicating their potential as a solution for improving live feed in fish larviculture.
