Water quality standards and plankton species composition in selected river system in Cagayan de Oro City, Philippines

This study describes the water quality standards in terms of physico-chemical characteristics of river system in Cugman and Bigaan Rivers and the composition of plankton species (Phytoplankton and Zooplankton). Specifically, this study determined if there are differences in physico-chemical properties and plankton composition in upstream, midstream and downstream water samples (Class B Classification) and compared […]

Biodiversity of lebak deling swamp in Pampangan, Ogan Komering Ilir Regency, South Sumatera Province, Indonesia

Investigation on biodiversity of Lebak Deling swamp in Pampangan, Ogan Komering Ilir Regency, South Sumatra Province was carried out from March to September 2011, focused on evaluating the diversity of benthic organisms, planktons, aquatic plants, fish and other wild animals in the swamp ecosystem. Five sampling stations were selected within Lebak Deling swamp area, i.e., […]

The dynamics of plankton compositions in juvenile-larvae gut of marble goby fish (Oxyeleotris marmorata Bleeker) collected from Hampalam river and pond in Kapuas Regency, Central Borneo

Appropriate and required feed types are optimally needed to support the viability and growth of Marble Goby Fish (Oxyeleotris marmorata). This research aimed to analyze species, composition, dynamic and density of plankton in gut of Marble Goby juvenile-larvae from Hampalam River and communities’ dykes of Batanjung Village, Kapuas Regency, Central Borneo in 6 stations for […]

Ecological relationship between the physico-chemical variables and the dynamics of ciliated protozoa in a tropical aquatic-system (Cameroon)

The eco-dynamical relationship has been established between the environmental variables and the distribution of ciliated protozoa in an aquatic ecosystem in Yaounde, Cameroon that is being subjected to anthropogenic pollution. These biological indicators for polysaprobic and mesosaprobic lotic and lentic systems were more exigent for biotopes with a high level of biodegradable organic and mineral […]

Effect of covering water surface with azolla (Azolla filiculoides Lam.) on water quality, growth and production of nile tilapia fed practical azolla-diets in earthen ponds

Although common in Africa’s rural areas, covering fish pond with Azolla is an extensive aquaculture practice that generates lower fish growth performances. To improve fish yield, a 90-days experiment was implemented to evaluate the effects of several Azolla cover (AC) levels on water nutrient, plankton dynamic, growth and production of Nile tilapia supplementary fed in […]

Limnological features of Ikere Gorge Reservoir, Iseyin south-western Nigeria: Plankton composition and abundance

A study of plankton composition of Ikere gorge reservoir Iseyin, South Western Nigeria was conducted from July to December 2007. The plankton taxa encountered were- Protozoa (10), Rotifera (9), Copepoda (4) Cladocera (4), Ostracoda (1), Insecta (1), Arachnida (1), Cyanophyceae (7), Bacillariophyceae (8), Chlorophyceae (22) and Euglenophyceae (1). Chlorophyceae were more abundant among phytoplankton throughout […]
