Litter processing and shredder distribution as indicators of riparian and catchment influences on ecological health of tropical streams
(Ecological Indicators, 2014-05)
Terrestrial plant litter is the main source of energy for food webs in forest headwater streams. Leaf litter quality often changes when native tree species are replaced by exotic ones and land use change in
the watershed ...
Macroinvertebrate functional feeding groups in Kenyan highland streams: evidence for a diverse shredder guild
(The Society for Freshwater Science, 2014-02)
Data on the functional composition of invertebrates in tropical streams are needed to develop models
of ecosystem functioning and to assess anthropogenic effects on ecological condition. We collected macroinvertebrates ...
Are Large Herbivores Vectors of Terrestrial Subsidies for Riverine Food Webs?
(Springer Science+Business Media New York, 2015-03-17)
The tropical savannas of Africa have witnessed a
dramatic reduction in native large mammalian
herbivore populations. The consequences of these
changes for terrestrial-aquatic food-web linkages
are poorly documented. ...
Genetic identification of invasive walking catfish, Clarias batrachus, intermingled with African catfish, C. gariepinus, in South Africa
(African Journal of Wildlife Research 45(1): 55–62 (April 2015), 2015-04)
Molecular genetic techniques were used to determine the identity of two catfish individuals
that could not be identified as indigenous Clarias gariepinus after phenotypic analysis. The
unidentified catfish were compared ...
On-farm growth performance of different strains of tilapia, Oreochromis niloticus reared in earthen ponds
(Aquaculture, fish and fisheries, 2023)
The growth of aquaculture sector in Kenya has been anchored on farmed Nile tilapia
Oreochromis niloticus. Different strains of the species exist in Kenya with unknown qual-
ity due to lack of stock improvement programmes ...
Some Aspects of Fish Biology and Ecology of River Perkerra in Lake Baringo Basin, Kenya
(Journal of Aquatic and Terrestrial Ecosystems, 2023)
Human activities including construction of dams along the river ecosystems may result in ecological changes in
the fish and fisheries. This study assessed some aspects of fish biology and ecology of River Perkerra in ...
Sediment Heavy Metal Pollution Assessment in Changwang and Wuyuan Rivers in Hainan Island, China
(Water, 2023)
Heavy metal pollution may pose a significant threat to aquatic ecosystems. To assess
heavy metal pollution, sediment samples were collected from Changwang and Wuyuan Rivers
between June and December 2019. An inductively ...
Effect of Stocking Density on Growth Performance, and Survival of Nile Tilapia (Oreochromis niloticus) in Cage Culture System in Lake Victoria, Kenya
(African Journal of Education, Science and Technology, 2023-04)
The Nile tilapia (Oreochromis niltoticus) constitutes an important animal protein source in the Great African Lakes population but wild supplies are rapidly declining. Cage aquaculture of O. niloticus is increasingly being ...
Effect of Different Fish Feed Sources on Growth and Economic Performance of Nile Tilapia (Oreochromis niloticus) Within Subsistence Setup in Liberia
(African Journal of Education, Science and Technology, 2023-05)
The wide adoption of O. niloticus for farming, particularly among smallholder farmers, can be attributed to its feeding versatility. However, its production in Liberia remains low, despite possessing desirable culture ...
Role of multilateral development organizations, public and private investments in aquaculture subsector in Kenya
(Frontiers in Sustainable Food Systems, 2023-08)
Rapid population and economic growth, increased health benefits of aquatic food,
and changes in lifestyles and preferences as a result of rapid urbanization and
globalization are all contributing to the rapid growth of ...
