Effects of Tribulus terrestris extract and 17 α-methyl testosterone on masculinization, growth, economic efficiency and health assessment of Nile tilapia (Oreochromis niloticus)
Monosex (male) Nile tilapia had three times better growth than the female. The excessive and unobservable use of hormones for fish production and sex reversal negatively affects fish production, profitability, fish, and human health but the optimum MT and TTE intake has a favorable impact on fish growth, health and profitability. Fish sex reversal has been significantly affected by phytochemicals, which are currently being investigated as a natural alternative agent. Thus, this study aimed to investigate the effects of dietary inclusion of Tribulus terrestris extracts (TTE) and 17α-methyl testosterone on sex reversal, growth performance, survivability, and adaptability for Nile tilapia. A 66-day trial was conducted with four formulated diets: T1 (40 mg/kg of 17α-MT + TTE), T2 (50 mg/kg of 17α-MT + TTE), T3 (60 mg/kg of 17α-MT + TTE) and a control diet (T4). The fish were fed 36% dietary protein and daily ration of feed ranged from 10 to 14% of their body weight and feeding frequency up to eight times a day. Eight hundred healthy seeds (0.02 ± 0.01 g initial weight) were randomly distributed (2000 fish/tank) in four concrete tanks (548 cm × 213 cm × 100 cm) each; length × width × depth). The maximum weight gain (WG), final body length (FBL), final body weight (FBW), average daily weight gain (ADWG), survival rate (SR), specific growth rate (SGR), sex reversal, profitability and lower feed conversion ratio (FCR) of Nile tilapia were recorded in T2, significantly varied compared to the other treatments (p < 0.05). The highest percentage (100%) of tilapia males was observed in T2, which was significantly different from other treatments (p < 0.05). T2 (50 mg kg−1 of 17α-MT + TTE) showed the highest growth in Nile tilapia and had a major impact on fish health, blood, and morphological indices. The phenomenal regression also indicated that the T2 dose is optimum for 100% Oreochromis niloticus mono-sex seed production.
期刊介绍：
Aquaculture International is an international journal publishing original research papers, short communications, technical notes and review papers on all aspects of aquaculture.
The Journal covers topics such as the biology, physiology, pathology and genetics of cultured fish, crustaceans, molluscs and plants, especially new species; water quality of supply systems, fluctuations in water quality within farms and the environmental impacts of aquacultural operations; nutrition, feeding and stocking practices, especially as they affect the health and growth rates of cultured species; sustainable production techniques; bioengineering studies on the design and management of offshore and land-based systems; the improvement of quality and marketing of farmed products; sociological and societal impacts of aquaculture, and more.
This is the official Journal of the European Aquaculture Society.
