IntroductionFish are the most feed converser than all terrestrial animals' species. So, the world population consumes 17% of their food protein from fish. Nowadays, aquaculture production in Egypt reached to 80% of the total local fish production (GAFRD, 2016 and Abdelhamid, 2019b). Milstein and Svirsky (1996) reported that an appropriate-adequate fish density will utilize the available resources ...

IntroductionPress and Evensen (1999) mentioned that species variation in the morphology of the immune system is to be expected, given the large number and diversity of species within the teleost fishes. Several external and internal factors can influence the activity of innate immune parameters. Temperature changes, handling and crowding stress can have suppressive effects on innate parameters, wh ...

But the Aqua-feeds are shorter than the demands, besides their expensive costs; therefore there is a need to recycle and reuse all possible and available field and industrial by-products that have a nutritional importa ...

IntroductionMuch information is given (Willem Van Cotthem, 2012) about Opuntia ficus-indicaasan aloes. Therefore, the aim of the present study was evaluating the possibility of using powders of either fruits' skins or leaves of the Egyptian Teen Shoky as replacers for dietary corn in all-males mono-sex Nile tilapia, Oreochromis niloticus diets and their effects on fish performance for 75 days. Thi ...
