Digestibility, Growth And Economic Performance Of Nile Tilapia (Oreochromis Niloticus) Fed On A Mixture Of Plant Protein Diets In Cages.

ABSTRACTFish feed is one of the critical components in aquaculture production and accounts forover 60% of total operational costs with protein component being the most expensiveingredient. Traditionally, fishmeal (FM) has been the primary dietary animal proteinsource. However, with dwindling capture fisheries, FM has become increasinglyscarce and expensive due to its demand from human consumers and livestock feedmanufacturers. This in turn makes the cost of fish feeds expensive leading ...

Molecular Characterization Of Edwardsiella Species Isolated From African Catfish (Clarias Gariepinus) And Nile Tilapia (Oreochromis Niloticus) In Wakisodistrict, Uganda

ABSTRACT Edwardsiella tarda is an opportunistic pathogenic bacterium that causes Edwardsiellosis in cultured and wild fish. It is among the most important bacterial diseases causing severe economic losses in fish worldwide. This study was carried out to determine the occurrence and characterize E. tarda in cultured Nile tilapia and African catfish from selected fish farms in Wakiso district, Uganda. A total of 111 fish samples were collected from 17 fish farms between September 2016...

Assessment Of Presence Of Oestrogen E1, E2 And Ee2 In Lake Kariba, Zambia

ABSTRACT Oestrogens are hormones, naturally produced by mammals or synthetically produced as drugs used in hormone therapy or as contraceptives. In the recent past years, oestrogens have gained much recognition due to their detrimental effect to aquatic life, which ranges from induction of intersexuality to complete reproductive failure of fish. Their main source in the aquatic environment is attributed to human and livestock waste and residues of oestrogens are found in water downstrea...

Identification And Characterization Of Flavobacteriaceae From Farmed Nile Tilapia (Oreochromis Niloticus) And African Catfish (Clarius Gariepinus) In Uganda

ABSTRACT Bacteria under family Flavobacteriaceae (in this study were also referred to as Flavobacteria) are important pathogens of fish, people, many other animals and plants. In this study, Flavobacteria from Nile tilapia (Oreochromis niloticus) and African catfish (Clarius gariepinus) were identified and characterized from the selected farms in Uganda. Gill and skin swabs were obtained from a total of 119 fish from 19 farms and were dissected aseptically to sample internal organs. The...

Assessment Of Levels And Effects Of Selected Heavy Metals Community of Wild Fish In Kafue River, Zambia

ABSTRACT The current study aimed at establishing the levels and effects of heavy metals on immunity of fish in the Kafue River basin. The heavy metals analysed in fish muscle and soil included Copper, Zinc, Cobalt, Nickel, Chromium, Lead, Iron, Cadmium and Manganese using Atomic Emission Spectrophotometer. The study found the concentrations of heavy metals to be lower than set standards by FAO and WHO with Copper being the only metal showing significant differences between the sexes...

Development And Validation Of Indices Of Quality Of Lake Victoria Nile Perch (Lates Niloticus) Marketed In Tanzania

ABSTRACT This study was conducted to validate the Quality Index Method (QIM) scheme and determine storage days on ice for domestically processed Nile perch (Lates niloticus). Samples collected from the fishermen at landing site were used to develop the QIM and for shelf life study at 0ºC to -1ºC for 33 days. Those collected from fish factories and cold stores were used for validation. The study assessed the sensory, microbiological and chemical quality changes of Nile perch on ice. Th...

Pond Management Practices, Occurrence And Antimicrobial Resistance Of Streptococcus And Lactococcus Species In Cultured Tilapia In Morogoro, Tanzania

ABSTRACT Streptococcosis is a zoonotic disease of fish reported to cause significant losses in aquaculture, it is caused by bacteria from three major groups; Streptococcus, Lactococcus and Vagococcus. This study aimed to establish the occurrence and antimicrobial resistance of Streptococcus and Lactococcus species in farmed Tilapia in Morogoro. A questionnaire was administered to fish farmers to acquire information about management practices of fish ponds in relation to occurrence of St...

Assessment Of Management Practices And Occurrence Of Mycobacterium Marinum Infection In Selected Milkfish (Chanos Chanos) Farms In Zanzibar, Tanzania

ABSTRACT Milkfish farming in Zanzibar is at infancy stage, practiced at small-scale levels and faces a number of constraints including fish health problems. The purpose of this study was to assess the milkfish farming practices and possibilities for occurrence of Mycobacterium marinum infection in selected milkfish farms in Zanzibar, Tanzania. A questionnaire survey was administered to 24 milkfish farmers to acquire information on general management system, fish health and related probl...
