Aquaculture has been practiced in Egypt for millennia, but modern approaches have only recently adopted to maximize its output. Today, aquaculture production is the largest Africa with about one million tonnes per annum. In this review, different freshwater and marine fish species that are cultured reviewed; most important tilapias, followed by mullets carps. Current practices highlighted, which include extensive, semi-intensive intensive systems, integrated aquaponics rice-field...
Penetration of triactinomyxon–sporoplasms Myxobolus cerebralis through skin, fins, gills and buccal cavity have been demonstrated experimentally in rainbow trout. Furthermore the multiplication–stages penetrated reach cartilage via peripheral nerves central nervous system (CNS). This is contrast to assumption that agent reaches blood, lymph, and/or coelomic fluid. During first hour following penetration, sporoplasm migrates between epidermal cells. Then, it enters epithelia multiplies...
Koi sleepy disease (KSD), also known as carp edema virus (CEV), was first reported from juvenile colour in Japan the 1970s. Recently, this pox detected several European countries, including Germany, France and Netherlands. In England, addition to carp, outbreaks common are reported. KSD/CEV is an emerging infectious characterized by a typical behaviour, enophthalmia, generalized oedematous condition gill necrosis, leading hypoxia. High mortality, of up 80–100%, seen koi collected infected...
Antibiotic resistance is a global issue that threatens public health. The excessive use of antibiotics contributes to this problem as the genes antibiotic can be transferred between bacteria in humans, animals and aquatic organisms. Metallic nanoparticles could serve future substitutes for some conventional because their antimicrobial activity. aim study was evaluate effects silver zinc oxide against major fish pathogens assess safety vitro. Silver were synthesized by chemical reduction...
Bio-nanotechnology employing bio-sourced nanomaterial is an emerging avenue serving the field of fish medicine. Marine-sourced chitosan nanoparticles (CSNPs) a well-known antimicrobial and immunomodulatory reagent with low or no harm side effects on their human consumers. In this study, in vitro skin mucus serum antibacterial activity assays along intestinal histology, histochemical, gene expression analyses were performed to evaluate impact dietary CSNPs (5 g kg−1 dry feed) rainbow trout...
