Applicant's summary and conclusion
- Validity criteria fulfilled:
- not specified
- Conclusions:
- The dietary addition of CV82 had no adverse effects on Olive flounder Paralichthys olivaceus; on the contrary these results suggested that the suitable dietary CV82 level could be between 0.5 and 1.0% (corresponding to 0.4 - 0.8% charcoal) for the maximum weight gain, feed efficiency and vitality.
- Executive summary:
In (Yoo, Ji et al. 2005) a mixture of 80% charcoal and 20% wood vinegar (CV82) was added to the diet of olive flounder at 0, 0.5, 1.0, 1.5 and 2.0% of the total diet. The effects of dietary charcoal were determined on growth, body composition and vitality.The tested parameters were the following: weight gain, feed efficiency, survival rate, condition factor, hepatosomatic index, carcass composition, serum GOT and GPT activities and recovery time after anesthetization.The dietary addition of CV82 had no adverse effects on Olive flounderParalichthys olivaceus; on the contrary these results suggested that the suitable dietary CV82 level could be between 0.5 and 1.0% (corresponding to 0.4 - 0.8% charcoal) for the maximum weight gain, feed efficiency and vitality.
