Botanical Control of Multiple Drug Resistant Pseudomonas aeruginosa infection in Clarias gariepinus

Journal of Pure and Applied Microbiology
Pseudomonas aeruginosa is a Gram-negative, rod-shaped bacterium which can cause opportunistic infections in fishes. Ethanolic leaf extract of Moringa oleifera was used in the treatment of Pseudomonas aeruginosa infected Clarias gariepinus for a period of

TRIVALENT CHROMIUM (CR+3) IN DIETARY CARBOHYDRATE AND ITS EFFECT ON THE GROWTH OF COMMONLY CULTIVATED FISH [PDF]

, 2016
Trivalent chromium (Cr+3) is an essential trace mineral for fish bio-physiological functions. Researches on Cr+3 in the form of organic compound indicated that the mineral affected the bio-activity of insulin, the blood glucose influx, and subsequently ...

Shifting Trends in Aquaculture's Biological Potential to Address Food, Climate and Biodiversity Challenges

Fish and Fisheries, EarlyView.
ABSTRACT Aquaculture has expanded and intensified significantly since the mid‐20th century, affecting its contributions to food security, climate change and biodiversity conservation (FCB) outcomes. In particular, shifts in the composition of farmed species affect the sector's potential impacts on sustainable development.

Substituting fish meal with grasshopper meal in the diet of Clarias gariepinus fingerlings [PDF]

, 2005
The effect of inclusion of grasshopper meal on the growth, feed conversion ratio and survival of Clarias gariepinus fingerlings of mean weight 9.71g was investigated. The results show that the best growth and food utilization indexes were recorded in the

Freshwater fishes of the Waterberg aquatic ecoregion, South Africa: Diversity, taxonomic conflicts and conservation concerns

Journal of Fish Biology, EarlyView.
Abstract Southern Africa is a region denoted by both high levels of fish diversity, some of it cryptic and unrecognised by current taxonomy, and severely threatened freshwater ecosystems. The Waterberg, a key aquatic ecoregion of the greater Limpopo River basin in South Africa, represents an area with high terrestrial conservation value but is lacking ...

Comparative study of hatching rates of African catfish (Clarias gariepinus Burchell 1822) eggs on different substrates [PDF]

, 2005
The hatching rates of African catfish (Clarias gariepinus) eggs on four natural substrates: the roots of Nile cabbage (Pistia stratiotes), water hyacinth (Eichhornia crassipes), pond weed (Ceratophyllum dermasum) and green grass leaves (Commelina sp ...

Nitrogen excretion and oxygen consumption under severe hypoxia in siluriform fishes from the Amazon

Journal of Fish Biology, EarlyView.
Abstract Siluriform fishes collected from the Rio Negro and Rio Solimões proved to be highly resistant to aquatic hypoxia. In all four species analysed in this study, aquatic oxygen consumption significantly decreased from normoxic levels at water PO2 values near 1 kPa. Air‐breathing activity was observed only in Sturisoma sp. (Rio Negro).

Reproductive plasticity and environmental tolerance of invasive African catfish (Clarias gariepinus) in a tropical Brazilian river

Journal of Fish Biology, EarlyView.
Abstract Invasive alien species (IAS) pose a significant threat to biodiversity, particularly when endowed with high ecological and reproductive plasticity. The African catfish, Clarias gariepinus, is one such species, widely recognized for its ability to colonize and establish in diverse tropical ecosystems.

Effects of dietary cassava dough (Fufu) kitchen waste as a replacement for maize on growth performance of Clarias gariapinus fingerlings

International Journal of Aquatic Biology, 2018
The study was carried out to determine the growth performance of Clarias gariepinus fingerlings cultured in the circular plastic ponds and fed diets containing varying level of cassava dough (fufu) kitchen waste at 0, 2.5, 5, 7.5, and 10% levels of ...
