The present work evaluated the capability of Arthrospira platensis complete biomass (ACDW) and lipid-free (LFB) to remove ammonium ions (NH4+) from aquaculture wastewater discharge. Under controlled conditions in flasks filled with 100 mL distilled water (synthetic aqueous solution), a batch process ion-exchange was conducted by changing main parameters including contact times (15, 30, 45, 60, 120, 180 min), initial ion concentrations (10, 20, 40, 50, mg·L−1), pH levels (2, 4, 6, 8, 10) at...
Four hundred and fifty Nile tilapia (Oreochromis niloticus), each weighing ca. 4 g, were randomly allocated into five equal groups in triplicate. The first group acts as control (A0). A1, A2, A3 A4 fed on rations supplemented with diatom, Amphora coffeaeformis, at 2.5, 5.0, 7.5 10%, respectively, for 63 days. Assessment of fish growth, biochemical composition, erythrocyte alterations, gonadal maturation, serum biomarkers, liver intestinal pathogens was carried out to identify welfare. Fish...
nutrients, pigments, and chemical composition, seaweeds are divided into rhodophyta (red algae), phaeophyta (brown or chlorophyta (green algae) (Princely Dhanaraju, 2017).Similar to other types of plants, include different organic
Streptococcosis became one of the most dangerous bacterial diseases affects cultured marine and freshwater fish. In present study Streptococcus iniae was isolated from diseased Nile tilapia (Oreochromis niloticus) with investigation clinical signs, post mortem lesions focusing on histopathological changes in liver kidney using light Transmission Electron Microscope (TEM). Natural infected O. niloticus showed ascites, exophthalmia, presence hemorrhagic patches all over external body surface...
A field study on Streptococcus infection as a major cause for epidemic infections in Nile Tilapia aquaculture Kafr El-Shikh Governorate was conducted. This carried out to the gross lesions and post mortem finding of Streptococcsis Tilapia. isolated, then identified by Electron Microscopy (Scanning Microscope (SEM), Energy Dispersive X-Ray Analysis (EDAX) Transmission (TEM)) investigate phenotypic characteristics, ultra-structure bacterial cells. Clinical signs infected fish showed presence...
