Effects of Dietary Zeolite and Perlite Supplementations on Growth and Nutrient Utilization Performance, and Some Serum Variables in Common Carp, (Cyprinus carpio)
The study investigates the impact of dietary supplements of natural zeolite and perlite on the growth performance, nutrient utilization, and serum variables of common carp (Cyprinus carpio). Conducted over eight weeks, the experiment involved five different diets: a control diet and diets supplemented with 2.5% and 5% of either zeolite or perlite. Each treatment was replicated in three tanks with fish averaging 30 grams in weight.
Results indicated that the addition of zeolite and perlite, particularly at the 5% level, significantly improved growth performance compared to the control diet. The apparent digestibility coefficients (ADC) for dry matter and protein were also enhanced with the dietary supplements, with the highest values observed in the 5% zeolite and perlite groups. Additionally, the ash content in the bones and scales of fish fed the experimental diets was significantly higher than in the control group.
Serum analysis revealed that while magnesium and phosphorus levels remained unchanged, the calcium concentration increased with zeolite supplementation. Notably, glucose levels were significantly higher in fish fed the 5% zeolite diet, while serum sodium and cholesterol levels decreased with both zeolite and perlite additions. The study concludes that incorporating zeolite and perlite into common carp diets can serve as effective aquafeed ingredients, promoting growth and improving nutrient utilization.
This research paper is significant in the field of aquaculture as it explores alternative feed additives that can enhance fish growth and health. The findings contribute to ongoing discussions about sustainable aquaculture practices by suggesting that natural minerals like zeolite and perlite can be utilized to improve feed efficiency and fish health. This research is beneficial for aquaculture practitioners seeking to optimize feed formulations, reduce costs, and enhance the nutritional quality of fish diets. Furthermore, it opens avenues for further research into the long-term effects of these additives on fish health and aquaculture sustainability.
