Effects of Incorporating Spent Bleaching Clay from Palm Oil Refining in the Diets of African Catfish, Clarias gariepinus

Asian Fisheries Science, 2006
Spent palm oil bleaching clays contain 20 to 30% adsorbed oil that cannot be recovered economically. A feeding trial was conducted to determine the potential use of this energy-rich oil-laden by-product from palm oil refining in African catfish diets ...

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 ...

Oxygen consumption from air and water, ammonia and urea‐N excretion, and Na+ fluxes during progressive aquatic hypoxia in Amazonian armoured catfish Pterygoplichthys gibbiceps and Pterygoplichthys pardalis

Journal of Fish Biology, EarlyView.
Abstract The Amazonian loricariid fish Pterygoplichthys gibbiceps, from the Rio Negro, and Pterygoplichthys pardalis, from the Rio Solimões, are facultative air‐breathers that can use the stomach as an air‐breathing organ. Measurement of oxygen uptake under progressive aquatic hypoxia revealed a relatively high hypoxia resistance of both species.

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).

Relationship between the environment and the occurrence of invasive pumpkinseed Lepomis gibbosus in lotic and lentic habitats

Journal of Fish Biology, EarlyView.
Abstract The pumpkinseed Lepomis gibbosus is a freshwater fish species native to North America. It has been introduced to Europe, where it is recognized as one of the worst aquatic invaders due to its high adaptability and invasive potential. This study aimed to determine the presence of L. gibbosus in small to medium‐sized water bodies, both lotic and

Use of swan mussel (Anodonta cygnea (Linne, 1758)) as a feed additive for african catfish (Clarias gariepinus (Burchell, 1822))

Ribogospodarsʹka Nauka Ukraïni, 2021
Purpose. Uzbekistan aquaculture has a huge deficit of balanced feed. In a case of feed production from local ingredients, the problem is the lack of stable source of animal protein.

Integrative taxonomy reveals four new species of the armoured catfish genus Pareiorhina (Siluriformes: Loricariidae) from the upper Paraná River basin, Brazil

Journal of Fish Biology, EarlyView.
Abstract Four new species of the small‐sized armoured catfish genus Pareiorhina are described from mountain ranges in the Grande River drainage, upper Paraná River basin, based on morphological and molecular species delimitation methods. Molecular analyses based on the cytochrome oxidase subunit I (COI) marker recovered Pareiorhina as polyphyletic ...
