Effect of Roselle (Hibiscus sabdariffa) and ginger (Zingiber officinale) as feed additives, on growth and haematology of Clarias gariepinus Juvenile

Abstract

The rebirth and use of medicinal plants in aquaculture has become necessary as the use of synthetic drugs and chemicals is been discouraged due to their aftermath effects on cultured organisms and aquatic environment. A 56-day study was conducted to assess the effects of Roselle and ginger as dietary additives, on growth and hematology of Clarias gariepinus juvenile. Total of 150 C. gariepinus juveniles (35.41±1.45 g) were assigned to five iso-nitrogenous diets as treatments having ginger and roselle added as additives at varying inclusion levels of 0.0, 2.0, 4.0, 2.0 and 4.0 g/100 g. Best growth performance was observed in 4.0 g ginger treated fish followed by 4.0 g roselle fed fish group, while 2.0 g roselle fed fish had the lowest growth performance. Significant changes (p˂0.05) were observed in the haematology of C. gariepinus fed varying inclusion levels of ginger and roselle. Highest values for red blood cells (4.07±0.08), haemoglobin (11.61±0.57) and pack cell volume (34.33±0.88) were seen in 4.0 g ginger treatment group followed by the control (3.63±0.22, 9.93±0.92 and 30.33±2.73), respectively. No significant changes were observed in red blood cells indices (mean corpular volume, mean corpular hemoglobin and mean corpular hemaglobin concentration). The current study revealed that fish fed 4.0 g ginger diet had better growth and haematological profile.

In-vitro antioxidants, antimicrobial and toxicological evaluation of Nigerian Zingiber officinale

“…It has been reported for antioxidants and protective role against toxicants, insecticidal, antimicrobial and antiprotozoal activities [11][12][13][14]. It has also been recently been reported to improve growth performances in experimental animals [15]. It is considered as a safe herbal medicine with only few and insignificant side effects [16].…”

The Effects of Roselle (Hibiscus sabdariffa) Calyx as Dietary Additive on the Growth Performance, Nutrient Utilization, and Haematological Parameters of Clarias gariepinus Fingerlings.

“…The weight gained might be due to the addition of roselle in the diets of the fish. Earlier studies by Ogueji et al (2017) and Kumar et al (2014) reported that plants have growth promoters for use in fish nutrition. Findings from this study agrees with Ogueji et al (2017) who obtained higher growth performance from C. gariepinus juvenile fed roselle and ginger supplemented diets compared to the control.…”

Findings from this study agrees with Ogueji et al (2017) who obtained higher growth performance from C. gariepinus juvenile fed roselle and ginger supplemented diets compared to the control. Furthermore, findings of this study agrees with earlier report by Adewole, (2014) who observed increased in growth parameters in C. gariepinus fed diet incorporated with roselle compared with the control.…”

“…Roselle (Hibiscus sabdariffa) calyx was found to have an antibacterial activity antagonistic to pathogenic A. hydrophila infection in Nile tilapia (El-Mesallamy et al, 2016). More so, roselle calyx demonstrated growth promoting ability in the diet of fish according to Adewole, (2014) and Ogueji et al (2017). Since research on antibiotic alternatives is crucial to ensure the sustainability of aquaculture, this study assessed the effects of roselle (Hibiscus sabdariffa) as a dietary additive on Clarias gariepinus fingerling growth performance, nutrient utilization and haematological parameters to improve aquaculture development.…”

The Effect of Suplementary Pelargonium sidoides Extract on Growth of the African Catfish (Clarias gariepınus (Burchell, 1822))

“…There are various reports of herbal fish diets promoting growth performance (Ji et al, 2007;Dada, 2012), increasing stress tolerance (Ji et al, 2009), and enhancing immune system effectiveness (Bai et al, 2009;Abdel-Tawwab et al, 2018). More recently such applications have begun to demonstrate positive effects in feeds for various fish species including African catfish, (Clarias gariepinus) (Turan & Akyurt, 2005;Turan & Çek, 2007;Turan & Yigitarslan, 2016;Ogueji et al, 2017), tilapia (Oreochromis aureus) (Turan, 2006), (Oreochromis niloticus) (Rawling et al, 2009), common carp (Cyprinus carpio) and crayfish (Astacus leptodactylus) (Turan et al, 2012).…”
