Article Synopsis
- This study examined the anaesthetic effects of fennel and anise essential oils on common carp, testing nine different concentrations for their effectiveness.
- Fennel oil proved to be an effective anaesthetic with minimal harmful effects on fish tissues, while anise oil led to deep anaesthesia but caused significant mortality at higher concentrations.
- Blood parameters remained mostly stable during anaesthesia except for reduced glucose levels in fish treated with anise oil, highlighting fennel oil as a safer alternative for anaesthesia in carp.
Article Synopsis
- The study assessed how S. officinalis (sage) essential oil affects the growth, health, and antioxidant activity in common carp (C. carpio) over a 60-day period.
- Fish fed with 1 ml/kg of sage oil showed an increase in superoxide dismutase (SOD) activity, but overall growth performance and other health markers remained unchanged.
- Importantly, carp experienced no mortality when exposed to a bacteria challenge after being fed with the sage oil, suggesting it improves gut health, disease resistance, and fertility in the fish.
This study was conducted to determine if diets supplemented with turmeric powder (Curcuma longa) affected the reversible sterilization of Pseudotropheus socolofi. Three experimental diets were formulated to contain 0%, 10%, and 14% turmeric powder. The fish (mean weight 13 g) were randomly divided into groups consisting of 1 male and 4 females for each aquarium and were kept together for 137 days.

The fish were fed dietary additions of 0%, 1%, 3%, 5%, and 7% turmeric powder. Each treatment was replicated three times.

Seven diets were prepared by adding β-mannanase, α-galactosidase and mixed enzyme at two different levels (1 g/kg and 2 g/kg) to control diet (without enzyme) including soybean meal. Mixed enzymes (1 g/kg, 2 g/kg) were prepared by adding β-mannanase and α-galactosidase at the same doses (0.
