Mapping of lacustrine aquaculture and socio-economic assessment cage farmers operations can be employed as decision support tools in an integrated fashion for fisheries management. We simultaneously mapped reported the location cages characterized indicators farming Lake Victoria, Kenya. Structured questionnaires interviews from generated data management information. Vital water quality parameters were analyzed selected sampling sites. Cage culture was found to a male-dominated activity with...
A 7-month experiment was carried out to determine the effects of different levels probiotics (baker's yeast (Saccharomyces cerevisiae) and Bacillus subtilis) on Nile tilapia (Oreochromis niloticus) reared in low input ponds. Monosex male fingerlings (40 g) were randomly distributed into 28, 1.25 m3 net cages at 50 fish m−3 fed twice daily 3% body weight seven isonitrogenous (28% crude protein) diets supplemented with either Saccharomyces cerevisiae (1 × 1010 CFU g−1) or subtilis 109 levels:...
Poor culture conditions in low input ponds make fish highly susceptible to infectious pathogens which lead diseases and mortalities yet the effects of probiotics on immunity, gut microbiota microbiological quality are unknown. Nile tilapia, Oreochromis niloticus fingerlings (40 g) were randomly stocked at 50 m−3 1.25 m3 cages ponds. The fed diets supplemented with either Saccharomyces cerevisiae (1 × 1010 CFU g−1) or Bacillus subtilis 109 six levels: Diet 0 (No probiotic); S. 2 g kg−1 (Diet...
Egypt is the topmost aquaculture producer in Africa and third largest tilapia globally. Nile particular cornerstone of fish farming Egypt. Recently, farms have experienced unusual mortality during summer season, threatening further growth sector. In order to understand risk factors, a questionnaire based cross-sectional study was conducted using epidemiology health economics online survey tools. We surveyed 113 four governorates (Kafr El Sheikh, Beheira, Sharqia, Faiyum) one governorate with...
The future demand for fish and other aquatic foods requires the sustainable intensification of related production systems. However, policy investment decisions aquaculture systems are hindered by lack benchmarking data on their actual sustainability performance, which often result in poorly developed implemented interventions that ignore potential trade-offs. This is a reality many leading developing country producers like Egypt. In this study we analyzed farm-level from 402 Egypt, to...
A total of 52 samples finished fish feeds and ingredients were collected from smallholder farmers in Kenya, Tanzania, Rwanda Uganda, analyzed. Culture molecular techniques used to identify fungal isolates the feedstock, mycotoxin profiles determined using liquid chromatography–tandem mass spectrometry. The most prevalent species recovered was Asperigillus flavus (54.5%). Other Aspergillus tamarii (9.1%), Mucor velutinosus (9%), Phoma sp. (6.1%), niger (6%), Eurotium rubrum (3%) Penicillium...
A number of studies have highlighted the promising growth Egyptian tilapia aquaculture and role genetically improved strains in this development, such as Abbassa Nile (Oreochromis niloticus, Linneaus, 1758). However, few explored link between development changes fish demand among low-income consumers. This study combines household budgeting questionnaires morphometric trait rankings conducted peak market season 2017 to examine patterns consumption preferences women men consumers across...
Saprolegniosis is a worldwide fungal-like infection affecting freshwater fishes and their eggs. Reports show high mortalities subsequent economic losses annually from Saprolegnia infections. Most therapeutants against spp. infections are inefficient some have negative impact on the environment. In this study, we investigated ability of boric acid (BA) to prevent in Nile tilapia (Oreochromis niloticus). BA inhibited radial growth hyphae vitro. Complete vitro inhibition was found at...
Commonly utilized feed ingredients for culture of Nile tilapia ( Oreochromis niloticus ) and Africa n catfish Clarias gariepinus from Kenya , Tanzania Rwanda were collected over a period six months (January - June 2010) evaluated their nutritive composition through proximate analysis. Most the fish found in all three countries except few that unique to one or two as detailed results . Feed animal origin exhibited significantly (P <0.05) higher crude protein levels (407 635 g/kg DM...
The effect of photoperiod (24L:00D, 12L:12D, and 00L:24D) temperature (22 ± 1°C 28 1°C) on performance Clarias gariepinus larvae was tested. Larvae weighing 3.2 0.24 mg were cultured in aquaria at a stocking density 20 fish L−1 fed twice day catfish starter diet (40% CP) 10 % BW day−1. Highest mean weight gain (31.00 mg), SGR (7.56% day−1), survival (83%) achieved combination 00L:24D 1°C. Percent differed significantly (p < .05) among treatments with optimal treatment 00L:24D, while lowest...
The following four species (only females available) of the Philometridae (Nematoda: Dracunculoidea) were recorded from freshwater fi shes Lake Turkana, northwestern Kenya in 2007-2008: Philometra bagri (Khalil, 1965) subcutaneous tissue around mouth, on gill covers and n base bayad Bagrus bajad (Forsskål) (Bagridae: Siluriformes), lati sp.n. abdominal cavity Nile perch Lates niloticus (Linnaeus) (Latidae: Perciformes), spiriformis capsules inner surface L.
