Digestive system of Nile bolti

Ingestion occurs during the day and digestion occurs mainly at night (Trewavas, 1983). The digestive tract of Nile tilapia is at least six times the total length of the fish, providing abundant surface area for digestion and absorption of nutrients from its mainly plant-based food sources (Figure 4) (Opuszynski and Shireman, 1995) The digestive system was empty at 18 h and the specific activities of the protease in all organs showed an increment from 18 h to their highest at 24 h, suggesting it was the best period after feeding for digestive tract sample collection to obtain the possible highest enzyme activity for further needed enzyme assays AMIN-INTESTINAL HELMINTHS OF SOME NILE FISHES TAKEN NEAR CAIRO, EGYPT 95 of middle of muscular esophagus (Fig. 2); pore ocassionally with elevated truncated rim broader at base.

  5. Digestive System. The esophagus in bony fishes is short and expandable so that large objects can be swallowed. The esophagus walls are layered with muscle. Most species of bony fishes have a stomach. Usually the stomach is a bent muscular tube in a U or V shape. Gastric glands release substances that break down food to prepare it for digestion

Alkaline proteinases extracted from fish digestive system (intestine, pyloric caeca, etc.) specifically cleaves peptide bonds mainly on the carboxyl side of lysine or arginine, except when either is followed by proline, and plays an important role in protein hydrolysis (Cao et al., 2000; Kishimura et al., 2008; Klomklao et al., 2007) Fish are poikilothermic and vary considerably in their feeding habits and temperature preferences, and so it is expected that their digestive enzymes will also exhibit diversity (El-Beltagy et al.

Oxygen and carbon dioxide dissolve in water, and most fishes exchange dissolved oxygen and carbon dioxide in water by means of the gills. The gills lie behind and to the side of the mouth cavity and consist of fleshy filaments supported by the gill arches and filled with blood vessels, which give gills a bright red colour. Water taken in continuously through the mouth passes backward between the gill bars and over the gill filaments, where the exchange of gases takes.

Egypt (22-32°N, 25-35°E) exhibits a great diversity of waters and water bodies in the Northeast of Africa. According to FAO (2010), Egypt has 2400 km of coastline in the Mediterranean and the Red seas. The total freshwater area in Egypt is estimated as 6000 Km 2, distributed mainly in the River Nile, its major two tributaries and many irrigation canals that flow through.

Abstract Glyphosate is considered toxicologically harmful and presents potential association with human carcinogenesis and other chronic diseases, including mental and reproductive behaviors. The challenges to analyse and demonstrate its toxicity are likely due to its metal-chelating properties, the interference of organic compounds in the environment, and similarity with its by-products.
