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.Link for e-copy: http://elibrary.narc.gov.np/?r=276 Changes In Zooplanktons Community And Density With Reference To Nutrients In A Subtropical Lake Begnas, Pokhara Valley [printed text] / MA.

Title : Effect Of Different Starter Feed On The Survival Rate And Growth Of African Catfish (Clarias Garjepinus) Fry Material Type: printed text Authors: RK. Shrestha, Author ; MA. Husen, Author ; Shrestha, B., Author ; SK Wagle, Author Pagination: 86-90 p. Languages : English (eng) Abstract: Formulation of the most desirable feed which satisfy the nutritional requirement of catfish ( Clarias gariepinus)
larvae is one of major task in development of aquaculture packages of practices of the catfish. To evaluate the
effect of live food organisms and several feed formulation on the survival and growth of catfish larvae
experiments were carried out. Treatments for starter feed includes zooplankton and artemia naupli as live food
organisms and carp micro-feed (formulated ration) were fed to the experimental catfish larvae.
The growth of catfish larvae was significantly (P<0.05) higher in zooplankton fed condition. The mean final
weight attained by catfish larvae was 197.3 mg and 126.7 mg, respectively, feeding with zooplankton and
artemia naupli. The mean survival rate for C. gariepinus fry fed on zooplankton and artemia naupli at the end of
4 weeks experiment was 53.3% and 56.8%, respectively. Absolute mortality was evidenced for larvae fed under
carp micro-feed. An increased zooplankton density in nursing water (423 to 1268/L) did not influence (P>0.05)
the growth of larvae. Larval growth was significantly (P<0.05) increased at increasing density ( 604 to 1813/L of
artemia naupli in nursing water. Survival rate of larvae was found to decrease as the feeding rate of artemia
naupli increased while zooplankton fed larvae showed increased survival rate (77.0 to 82.0%) in response to
increase in feeding rate.Link for e-copy: http://elibrary.narc.gov.np/?r=281 Effect Of Different Starter Feed On The Survival Rate And Growth Of African Catfish (Clarias Garjepinus) Fry [printed text] / RK.

Title : Preliminary Results On The Hybridization Between African Catfish (Clarias Gariepinus) And Asian Catfish (Clarias Batrachus) Material Type: printed text Authors: SK Wagle, Author ; AP Baidya, Author ; B Shrestha, Author ; MA. Husen, Author Pagination: 27-35 p. Languages : English (eng) Abstract: Hybrid was produced through cross breeding between native Asian catfish (C. batrachus) male and African
C. gariepinus. Heterosis could not be compared between Fl hybrids because of poor gametic viability ofthe
cross between C. batrachusC¥ and C. gariepinus (). Hybrid was compared at different stages from larval to
market size with its respective control sibs. The average performance traits (viz. fertility, hatching rate,
growth and survival) of individuals derived from cross between C. gariepinus~ and C. batrachus c3 was
significantly better than its one of the control sib (C. batraclms). Hybrid showed high rate (31.5%) of
deformity and abnormality in larval stage before the start of exogenous feeding and deformity extend until
maturity. Significant divergence in morph type resembling to both of their parents and corresponding growth
was found in hybrid population. In this preliminary study, hybrid showed heterotic in growth performance
trait which might have important implication for the aquaculture industry.Preliminary Results On The Hybridization Between African Catfish (Clarias Gariepinus) And Asian Catfish (Clarias Batrachus) [printed text] / SK Wagle, Author ; AP Baidya, Author ; B Shrestha, Author ; MA.

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.Link for e-copy: http://elibrary.narc.gov.np/?r=277 Temporal Change In Phytoplankton Abundance In Lake Phewa, Pokhara [printed text] / RP Dhakal, Author ; MA. Husen, Author ; SK Wagle, Author ; JD Bista, Author . - [s.d.] . - 59-64 p.
