Hypothesis
Can American cockroach residue effectively replace fishmeal in the diets of juvenile Cyprinus carpio without negatively affecting their growth and health?
Conclusion
Replacing fishmeal with up to 40% American cockroach residue improves growth performance and immune function in juvenile Cyprinus carpio, but higher levels may harm intestinal health.
Supporting Evidence
- Replacing up to 40% of fishmeal with American cockroach residue significantly improved growth performance.
- Juvenile C. carpio showed enhanced antioxidant capacity and immune function with moderate cockroach residue inclusion.
- Exceeding 40% replacement may adversely affect intestinal health, indicated by reduced goblet cell numbers.
Takeaway
This study shows that we can use American cockroach leftovers to feed fish, helping them grow better and stay healthy, but we shouldn't use too much.
Methodology
The study involved feeding juvenile Cyprinus carpio five different diets with varying levels of fishmeal replaced by American cockroach residue over a 10-week period.
Limitations
The study did not explore the long-term effects of high levels of cockroach residue on fish health.
Participant Demographics
Juvenile Cyprinus carpio with an initial body weight of approximately 74 g.
