“…Alkalinity, pH, low DO, high BOD and high nutrient concentration were observed during the bloom periods in the pond. The coincidence of cyanophyceae bloom with relatively higher temperature, pH and nutrient concentration levels high in summer was observed in the present study agree with the findings of Affan et al (2005). Jewel et al (2006) reported that Microcystis species was found to be controlled by relatively high temperature (> 25 °C) and nutrient enrichment, especially high nitrogen concentration.…”

ABSTRACT. The occurrence and abundance of Microcystis aeruginosa were monitored monthly in eutrophic pond water of Ilamiyakkinar temple pond from July 2014 to June 2015. Some environmental factors such as water temperature, pH, free carbon-dioxide (FCO 2 ), total alkalinity, Dissolved oxygen (DO 2 ), biological oxygen demand (BOD), nitrate (NO 2 -N) and phosphate are recorded and their relationship with the bloom formation by Microcystis aeruginosa were discussed. The initiation and persistence of Microcystis aeruginosa were founded to be triggered by relatively high water temperature (24 °C to 36.5 °C), pH (7.3 to 8.72) and NO 2 -N concentration.

“…According to Affan et at. [40], moderate temperature and clear sunlight may reasons for the dominance of euglenophytes. Phang and Ong (1988) [49] reported that Euglenoides were dominant at elevated temperature.…”

The study measures the relationship between physico-chemical variables with the cell density of phytoplankton in nursery, growout and broodstock ponds of fish. This study was conducted at Natore Government Fish Farm in Bangladesh from January to June, 2012. The observed physico-chemical variables like water temperature, transparency, dissolved oxygen, pH, ammonia-nitrogen, total alkalinity and total hardness were found within the standard ranges. Phytoplankton belonging to bacillariophyceae, chlorophyceae, cyanophyceae and euglenophyceae were found among the ponds but euglenophyceae with highest abundance was recorded in almost all the ponds. Total abundance of different groups of phytoplankton was recorded as mean (±SD) cell density (cell/l) (62.77±2.16)×10 4 , (47.22±0.69)×10 4 , and (77.12±3.42)×10 4 in nursery pond, growout pond and broodstock pond, respectively. Overall phytoplankton abundance was more in broodstock pond than in others. Total phytoplankton density has exhibited significantly positive correlation with dissolved oxygen (DO) and inverse relation with water temperature, pH, ammonianitrogen and total alkalinity in case of nursery pond. For growout pond, total phytoplankton density has exhibited significantly positive correlation with temperature and transparency, and significantly negative correlation with other physico-chemical characteristics. In case of broodstock pond, total phytoplankton density has no significant relationship with any physico-chemical variables of water.

“…Perubahan kandungan nutrien dalam kolam tambak dapat disebabkan oleh adanya variasi temporal kualitas lingkungan (Affan et al, 2005). Perubahan kondisi lingkungan secara temporal berdampak pada tingkat suplai nutrien ke dalam kolam tambak yang salah satunya dipengaruhi oleh keberadaan tanaman sebagai produsen serasah (Gotelli et al, 2008).…”

ABSTRAKKeberadaan vegetasi mangrove dalam tambak wanamina berfungsi sebagai penyedia jasa lingkungan, diantaranya dalam pengendalian suplai nutrien ke dalam kolam. Penelitian ini bertujuan untuk mengkaji variasi kandungan nutrien dalam tambak wanamina dan menguji pengaruh jenis serta jumlah tegakan terhadap perubahan kandungan nutrien tambak wanamina. Penelitian dilaksanakan selama 4 bulan dengan perlakuan jenis vegetasi (A. marina; R. mucronata; Campuran) dan jumlah tegakan mangrove (5 tegakan; 10 tegakan; 15 tegakan). Kandungan nutrien yang diamati meliputi bahan organik, nitrat, nitrogen dan fosfat terlarut. Pengamatan dilakukan sebanyak 2 kali dengan jeda waktu 1 bulan. Pengujian dilakukan dengan uji-t dan ANOVA. Hasil pengamatan menunjukkan bahwa terdapat variasi kandungan nutrien dalam tambak wanamina baik pada pengamatan pertama maupun kedua. Pola perubahan kandungan nutrien bervariasi antar jenis nutrien dimana pada beberapa perlakuan ditemukan penurunan kandungan semua jenis nutrien. Hasil uji-t menunjukkan bahwa antar periode pengamatan tidak terdapat perbedaan yang signifikan terhadap kandungan bahan organik, nitrat, nitrogen dan fosfat terlarut. Hasil ANOVA menunjukkan bahwa tidak terdapat pengaruh yang signifikan terhadap kandungan nutrien dalam tambak wanamina baik pada pengamatan pertama maupun kedua. Perbedaan kandungan nutrien yang signifikan hanya diperoleh pada kandungan bahan organik pada pengamatan pertama. Kata kunci: jenis, jumlah tegakan, mangrove, nutrien, wanamina ABSTRACTThe presence of mangrove vegetation in silvofishery ponds provide environmental services, such as controling nutrient supply to the ponds. This research aimed to study the variations of nutrient concentration in silvofishery pond and to analyze the effect of mangrove species and stand population on the change of nutrient concentration in silvofishery ponds. Research was conducted for 4 months involving treatments of mangrove species (A. marina; R. mucronata; Mixed) and stand population (5 stands; 10 stands; 15 stands). Concentration of nutrient observed in this research were dissolved organic matter, nitrate, nitrogen and phosphate. Observations were conducted twice with spare period of 1 month. Analysis were conducted with ttest and ANOVA. The observation result showed there were variation of nutrient concentration in silvofishery pond for both first and second observations. Change pattern of nutrients were varied among nutrient types, were some treatments showed consistent decrease for all nutrient types. Result of t-test showed there were no significant difference of dissolved organic matter, nitrate, nitrogen and phosphate resulted from first and second observations. ANOVA showed generally there were no significant efect of the treatments on the concentration of nutrient in silvofishery pond partially in first observation and second obsercation. Significant difference of nutrient concentration was achieved from organic matter in first observation.
