Water Quality Management in Fish Hatchery and Grow-Out Systems

Dietary inclusion effect of ginger (Zingiber officinale) and garlic (Allium sativum) blend on growth, feed nutrients utilization and retention in African Catfish (Clarias gariepinus) fry in intensive system

“…Indeed, water quality parameters, which are the result of the rearing system have a great infl uence on fi sh survival as well as growth, especially at the fry stage. The physico-chemical parameters of the rearing medium such as temperature and dissolved oxygen recorded during the present study were observed to be within the range recommended for freshwater fi sh culture [32,33]. [33] recommended temperature values between 25 and 30°C for rearing of C. gariepinus.…”

Effect of stocking densities on the growth performance, cannibalism and survival of Asian seabass Lates calcarifer (Bloch, 1790) fry in different nursery rearing system

“…The recorded water temperature, DO, pH, NH 3 , NO 2 and Alkalinity, was within the suitable range in all treatments required for Asian seabass (Schipp et al, 2007; Kungvankij et al, 1985; Rimmer and Russell, 1998; Saraswathy et al, 2015). During the experiment, the water temperature was dominated by room temperature.…”

“…The NO 2 concentrations were 0.74 ± 0.08 mg/L in the RAS and 1.01 ± 0.15 mg/L in the SWS during the present study but compared with earlier reports it was in acceptable range in brackish water for Asian seabass (Rimmer and Russell, 1998; Blancheton, 2000). The alkalinity of water in each treatment was recommended for aquaculture (Saraswathy et al, 2015).…”

Effect of <i>Zingiber officinale</i> and <i>Allium sativum</i> Powders as Natural Feed Additives Promoting Growth, Feed Utilization and Whole-Body Composition in <i>Clarias gariepinus</i> Fry

“…Many findings have reported that addition of medicinal plant products or by-products to diet favour various activities like growth promotion, appetite and digestion stimulation, antistress, enhancement of tonicity and immune stimulation and antipathogen properties in fish and shrimp aquaculture [29] [30]. In the present study carried out to evaluate the effects of dietary inclusion of Zingiber officinale and Allium sativum powders on growth, feed utilization and whole-body composition of Clarias gariepinus fry raised under intensive farming condition, the physico-chemical parameters of the breeding medium such as temperature and dissolved oxygen were observed to be within the range recommended for freshwater fish culture [31]. Bhatnagar et al [32] recommended 25˚C -30˚C for culture of C. gariepinus.…”
