Changes In Zooplanktons Community And Density With Reference To Nutrients In A Subtropical Lake Begnas, Pokhara Valley / MA. Husen ; RP Dhakal ; SK Wagle ; JD Bista    

Public ISBD in Proceedings of the 7th (seventh) National Workshop on Livestock and Fisheries Research, June 22-27, 2007 / Shrestha, B.S.     Title : Changes In Zooplanktons Community And Density With Reference To Nutrients In A Subtropical Lake Begnas, Pokhara Valley Material Type: printed text Authors: MA. Husen, Author ; RP Dhakal, Author ; SK Wagle, Author ; JD Bista, Author Pagination: 54-58 p. Languages : English (eng) Abstract: Several species of zooplankton are used as indicators to identify different physico-chemical advection ?r eutrophic changes in lake. Seasonal variation of zooplanktons and nutrients plays an important role m ecosystem alteration of aquatic environment. Knowledge on nutrients and plankton dynamic of the lake provide basis for modality and extent of exploitation of fishery resources of the lakes. Therefore, monthly zooplankton and nutrients data collected from five different depth gradients of Lake Begnas for year 1995 and 2005 were analyzed and compared to investigate changes in zooplankton community and density.

Temporal Change In Phytoplankton Abundance In Lake Phewa, Pokhara / RP Dhakal ; MA. Husen ; SK Wagle ; JD Bista    

Public ISBD in Proceedings of the 7th (seventh) National Workshop on Livestock and Fisheries Research, June 22-27, 2007 / Shrestha, B.S.     Title : Temporal Change In Phytoplankton Abundance In Lake Phewa, Pokhara Material Type: printed text Authors: RP Dhakal, Author ; MA. Husen, Author ; SK Wagle, Author ; JD Bista, Author Pagination: 59-64 p. Languages : English (eng) Abstract: Phytoplankton is one of the key suppliers of energy in aquatic ecosystem. phytoplankton abundance, composition and activity affect dynamics of other organisms. Since, phytoplankton abundance and growth condition is important to elucidate fisheries; therefore their abundance was examined from January to December 2006. A total of twenttthree phytoplankton species were collected, where the mean monthly abundance was 2.0 xi03 cells.mL· , with relatively higher values during June, August and November (3.1- 4.09 xl03 cells.mL" 1 ). The predominant phytoplankton were Microcystis aeruginosa, Merismopedia tennuissima and Peridinium sp. Among all Dinophyceae and Cyanophyceae increased significantly (P<0.05) with increasing total phosphorous. The current trend of phytoplankton abundance has been discussed in relation to fisheries management in Lake Phewa.
