Hypothesis
Different dietary protein sources influence the survival, growth, and physiology of marron exposed to feed deprivation.
Conclusion
Marron fed animal-based protein sources showed better health and survival during starvation compared to those fed plant-based proteins.
Supporting Evidence
- Animal-based protein sources resulted in higher immunity of starved marron than plant-sourced protein.
- All starved marron showed more than 83% survival, but those fed soybean meal had significantly lower survival.
- Lysozyme activity and total haemocyte count decreased significantly during the starvation period.
Takeaway
Marron, a type of crayfish, can survive without food for a long time, but what they eat before starving matters a lot for their health.
Methodology
Marron were fed different protein sources for 110 days, then starved for 45 days while their health and immunity were assessed.
Potential Biases
Potential bias in dietary treatment effects due to environmental factors not controlled in the study.
Limitations
The study was limited to a specific duration of starvation and did not explore long-term effects beyond 45 days.
Participant Demographics
0+marron (Cherax cainii) from various dietary treatments.
