Abstract:
The high cost of fish feed has affected the culturing of tilapias and sharptooth catfish in Africa. However, Africa is well endowed with terrestrial insects that can potentially replace fishmeal in the diets of fish. In this paper, the nutritional index, availability, and cost of selected insect meals are compared. The SOLVER function in Excel was used to formulate least-cost diets of Musca domestica, Gryllotalpa africana, Schistocerca gregaria, Macrotermes natalensis, and Gonimbrasia belina. The crude protein levels of all the insects were above 50% and met the requirements of both fish speci

The work is devoted to the study of trecresan adaptogen effect on hematological parameters of sharptooth catfish bred in an artificial environment. In particular, the effect of trecresan on general hematological parameters and antioxidant system of African sharptooth catfish was assessed, since breeding in an artificial environment is accompanied by stress, in which oxidative processes increase, leading to damage of biological membranes and disruption of cell functioning. Blood samples were analyzed using an Axio Imager.M2 microscope (Carl Zeiss, Germany). The analysis of enzymatic activity (u

The work is devoted to the study of qualitative and quantitative characteristics of African sharptooth catfish caviar produced at different periods of the inter-spawning interval, obtained artificially under the influence of reproductive hormones. In industrial aquaculture, the African catfish does not reproduce naturally, so the problem of obtaining high-quality caviar suitable for artificial insemination is relevant. To carry out the reproductive process in fish in industrial aquaculture, it is necessary to choose the right sex hormone and its dose. Sex hormones affect the duration of the in

Invasive species are of particular concern as they have the potential to alter community structure and food web relationships within their invaded habitats. African sharptooth catfish Clarias gariepinus, a generalist predator, was introduced through an inter-basin water transfer scheme into the Great Fish and Sundays Rivers, Eastern Cape, South Africa, where it threatens the native riverine biota.

In the Kruger National Park (KNP), pansteatitis in sharptooth catfish, Clarias gariepinus (Burchell), was shown to be a serious problem in the inlets to large man-made lakes fed by rivers arising in the polluted catchments of the Olifants and Sabie rivers. An increasing prevalence of pansteatitis was recorded in catfish from the Olifants River gorge. A low prevalence was found in catfish upstream of the gorge at two further sites. No pansteatitis was detected in catfish from a rain-filled dam distant from the potential pollution sources affecting the Olifants River and in rivers arising outsid

Past and current research on the biology and culture of the sharptooth catfish (Clarias gariepinus) has stimulated the development of its commercial production.

The objectives of the project were, therefore, to investigate aspects of the nutritional physiology and dietary requirements of the species to provide the necessary information for the formulation of optimum economical feeds.

However, digestible energy (DE) values for specific feed ingredients were unknown. As DE values are not interchangeable between species, this study set out to determine the DE values for conventional and unconventional feed-ingredients for the formulation of an optimal feed.

Although the Nile crocodile is still widely distributed in Africa, viable populations of wild crocodiles are nowadays only found in protected areas in South Africa, like the Kruger National Park and iSimangaliso Wetland Park. The sharptooth catfish, on the other hand, also has a wide distribution in Africa, but is still commonly found in nearly all waterbodies in South Africa. Biomarkers to determine the health stat

These chemicals are known as endocrine disrupting chemicals (EDCs). These compounds are highly persistent in nature due to a resistance to biodegradation, and because of their hydrophobicity.

Abstract:
The Rietvlei Dam near Pretoria, South Africa, provides drinking water for the city and for the wild life in the Rietvlei Nature Reserve, and is also used for recreational fishing. The dam is part of the Sesmyl Spruit system, which has a history of pollution, the major sources of which are industrial, agricultural and sewage from informal human settlements upstream of the reserve. With a large wetland separating the upstream Marais Dam and the Rietvlei Dam, the system has a high conservation priority status because of the high number of bird species that breed and roost in the various habitats.
