Refaey Animal Production Department, Faculty of Agriculture, Mansoura University, Al-Mansoura, Egypt ABSTRACT This study aimed to compare of using 17α-methyltestosterone (17α-MT), pawpaw (Carica papaya) seeds powder (PSP), and neem (Azadirachta indica) leaves powder (NLP) as reproductive controller agents for Oreochromis niloticus. This experiment was divided into

Ultrastructural data on the spore of Myxobolus dermatobius Ishii, 1915 (Myxosporea: Myxobolidae) infecting eye of Nile-tilapia (Oreochromis niloticus) in Egypt NOSSEUR M . EL-SAYED Department of Parasitology , Faculty of Veterinary Medicine, Zagazig University, Egypt.

procedure: 100. 75, 50 Furthermore 25% composted water hyacinth: 100, 75 what’s more 25% dried water hyacinth; and a control diet for 0% uprooting of the routine encourage. The test eating methodologies were nourished done copy medicines to Oreochromis niloticus to an arrangement for 16 open air 4-m3 tanks supplied with eight fish/tank for 84 days. Handy development Also encourage usage efficiencies were acquired for eating methodologies holding dependent upon 75% composted water hyacinth with no noteworthy

Fish Fraud has become increasingly common in fish markets and sushi restaurants where certain species are deliberately swapped for other species to obtain monetary gain (Shokralla, 2015). With the increasing globalization and demand for seafood, the biodiversity of fish species in the market increase as well (Shokralla, 2015). Moreover, a need for proper identification and product composition, apart from morphological characterization has become critical. Unfortunately, consumers are unable to differentiate

Today phylogeny is used all around the world in fields of all nature such as biology, history, and even forensic studies. It is the evolutionary history of a group of organisms. With that being said, term phylogenetics refers to the study of evolutionary relatedness among groups of organisms based on genetic similarities as well as the history and relationships among these organisms (Losos, 2013). This is extremely important in science because it allows scientists to study and determine the relatedness

Abstract: Water contamination is the defilement of characteristic water bodies by compound, physical, radioactive or pathogenic microbial substances. Unfriendly adjustment of water quality in no time delivers vast scale ailment and deaths, resulting of more than 50 million deaths for every year worldwide. Widespread results of water contamination upon environments incorporate species mortality, biodiversity decrease and loss of biological system administrations. Some consider that, the most dangerous

Introduction In the nineteenth century, two famous scientists - Robert Koch and Louis Pasteur - formally demonstrated that microorganisms were the cause of many diseases. This proposition has become known as "Germ Theory of Disease". Not that this notion had never been touched before - on the contrary, there have been ancient mentions as old as 36 BC from a roman scholar, Marcus Terentius Varro, that stated: “certain minute creatures, which cannot be seen by the eyes, which float in the air and

Magnetic iron oxide nanoparticles, such as Fe3O4 classified as biocompatible (Kunzmann et al., 2011) and low toxic nanomaterials in the human body studied (Jeng and Swanson, 2006; Karlsson et al., 2009) which make them have attracted great interest in biomedicine. However, little studies report in the human and existence the criteria to define the toxicity of nanomaterials does not guarantee that iron oxide nanoparticles pose no potential risks in a challenge with environmental systems and are suitable
