Biological and life-history parameters for Labeo rosae Steindachner, 1894 and Oreochromis mossambicus (Peters, 1852) from Flag Boshielo Dam, Olifants River, South Africa

Autor: Hlungwani, HA, Marr, SM, Weyl, OLF, Sara, JR

Inland fisheries contribute towards food security for rural communities living close to large aquatic systems. However, sustainable inland fisheries rely on accurate biological information for the target species at the proposed fishery location. In t

Macro- and micronutrient composition of estuarine roundherring (Gilchristella aestuaria) (Pisces: Clupeidae) in the Eastern Cape, South Africa: a potential dietary source of essential nutrients

Autor: Zvavahera, M, Hugo, S, Vine, NG, Weyl, OLF

Publikováno v: African Journal of Aquatic Science; Vol. 47 No. 2 (2022); 224-229

South Africa lacks research on the nutritional value of inland small fish species available to poor rural communities, despite the potential of such species to mitigate micronutrient deficiencies. Here we provide the first nutrient composition analys

Publikováno v: African Journal of Aquatic Science; Vol. 46 No. 4 (2021); 452–463

Irrigation ponds are increasingly abundant globally, particularly in water-stressed countries with limited natural surface waters, yet knowledge of their ecology is limited. Here, we assessed zooplankton, macroinvertebrate, and littoral fish communit

Invasive carp alter trophic niches of consumers and basal resources in African reservoirs

Autor: Dalu, T, Cuthbert, RN, Moyo, S, Wasserman, RJ, Chari, LD, Weyl, OLF, Jackson, MC

Publikováno v: Science of The Total Environment. 813:152625

Highlights: • Niche conservatism among reservoirs was generally higher in invertebrates. • Niche conservatism was not based on reservoir condition (i.e. presence or absence of pollution and/or invasion). • Invasion coupled with organic pollutio
