Effects crude protein levels on female Nile tilapia (Oreochromis niloticus) reproductive performance parameters

Reproductive performance of female Nile tilapia ( Oreochromis niloticus ) fed diets with different digestible energy levels

“…Coldebella et al (2013) evaluated different levels of soil oil for female catfish (Rhamdia quelen) and also observed no differences between treatments for the same variables; however, females fed diets with 140 and 200 g/kg lipids displayed greater accumulations of visceral fat. In contrast to these results, Oliveira et al (2014) observed an inverse relationship between hepatosomatic and gonadosomatic indices with a 380 g/kg crude protein level in the diet of adult female Nile Tilapia, with an initial average weight of 764 g.

“…The treatments consisted of five diets (Table 1) that were formulated to contain increasing levels of DE (3,200;3,400; 3,600; 3,800; and 4,000 kcal of DE/kg of diet) ( Table 2) according to the table of ingredient chemical composition, described by Furuya (2010). The digestible energy levels were obtained by increasing the levels of soybean oil in the feed and varying the starch/lipid ratio, with a crude protein content of 380 g/kg, according to Oliveira et al (2014). During the experiment, fish were fed twice a day (at 08.00 and 14.00 h) until apparent satiation to avoid leftovers and the tanks were cleaned daily to remove excreta.…”

“…The nutritional requirements for tilapia broodstock have not yet been defined in Brazil. Oliveira et al (2014) defined the level of dietary crude protein needed for broodstock; however, it is still necessary to establish the most appropriate amount of energy. Thus, the present study was conducted to evaluate the performance of female Nile tilapia fed diets containing different levels of digestible energy (DE) by varying the starch/lipid ratio.…”

Effects of α‐lipoic acid on growth performance, body composition, antioxidant profile and lipid metabolism of the GIFT tilapia (Oreochromis niloticus) fed high‐fat diets

“…The genetically improved farmed tilapia (GIFT tilapia, Oreochromis niloticus) through selective breeding has been used as a strain of fish stock in aquaculture (Boonanuntanasarn et al, 2018;Ng & Romano, 2013;Oliveira et al, 2014;Xie et al, 2017). Despite its wide use, little has been done to reduce effectively its costly dietary protein and nitrogen pollution in its culture systems (Oliveira et al, 2014). Provision of adequate energy by using dietary lipid or carbohydrate can minimize the use of costly protein and increase feed efficiency (He et al, 2015;Lim, Yildirim-Aksoy, Li, Welker, & Klesius, 2009;Ma et al, 2018;Pan et al, 2017;Xie et al, 2017).…”

Inclusion of Fresh Raw Material on Tilapia Fry Diets Growth Under Aquaponics System

“…Nutrition is an important aspect in aquaculture, as most of the production cost is related to the use of commercial food, thus, it is important to have information on other food sources that cover the nutritional requirements of Tilapia [27], especially in the juvenile stage, in order to formulate balanced diets that reduce nitrogen excretion and that are inexpensive such as soybean meal [13], lupins [17] and various oilseeds [21] have been widely explored.…”
