Phytoplanktons are free-floating microscopic plants in water and they the primary producers providing food to aquatic organisms. However, quality affects species production assemblage terms of diversity, composition, abundance. This study assessed spatial temporal diversity abundance phytoplanktons Gusii wastewater treatment plant. A total 124 phytoplankton were identified belonged six families...

Plankton is an important food item of fishes and indicator for the productivity of a water body. The present study was conducted to evaluate the effects of bottom soil textural conditions on abundance of plankton in aquaculture pond. The experiment was carried out using three treatments, i.e., ponds bottom with sandy loam (T1), with loam (T2) and with clay loam (T3). The ranges of water quality...

Marine ecosystems are undergoing substantial changes due to human-induced pressures. Analysis of long-term data series is a valuable tool for understanding naturally and anthropogenically induced changes in plankton communities. In the present study, seasonal monitoring data were collected in three sub-basins of the northern Baltic Sea between 1979 and 2011 and statistically analysed for trends...

Tibetan lake sediments in NW China are sensitive recorders of climate change. However, many important plankton members do not leave any microscopic features in sedimentary records. Here we used ancient DNA preserved in Qinghai Lake sediments to reconstruct the temporal succession of plankton communities in the past 18,500 years. Our results showed that seven classes and sixteen genera of phytop...

Selat Makassar merupakan lintasan pertama arlindo yang dimana ini sebagaian besar mentransfer air kemudian menuju selat Lombok. Arus lintas Indonesia membuat perairan terutama bagian timur menjadi subur akibat adanya proses upwelling dan pencampuran serta interaksi dengan udara menyebabkan kandungan nutrisi mineral kaya pada lapisan laut dalam. Beberapa penelitian tentang plankton di masih berk...

Determination observation stations using stratified random sampling method, identification census method analysis chlorophyll-a Trichomatic method...

This research was conducted in January 2020 the waters of Sembilan Dumai River which aims to determine concentration nitrate and phosphate on primary productivity phytoplankton. The method used this is survey while determination station done by technic purposive sampling. results showed that average ranged from 0.0194 - 0.0749 mg/l 0.1452 0.8502 mg/l. There are 6 classes phytoplankton found Riv...

Plankton merupakan organisme yang hidupnya melayang-layang di perairan pergerakannya dipengaruhi oleh arus. Keberadaan plankton suatu dapat digunakan sebagai bioindikator karena memiliki tingkat kepekaan tinggi dan juga perubahan kondisi perairan. Perubahan-perubahan diakibatkan adanya aktivitas masyarakat. Salah satu pantai banyak masyakarat yaitu Pantai Samuh. Penelitian ini dilakukan pada bu...
