Title : Diversity and marketing of dried fish products in Nepal Material Type: printed text Authors: N. Pradhan, Author ; M. K. Shrestha, Author ; S. Rai, Author ; D. K. Jha, Author ; Sanjit Kumar Saha, Author Publication Date: 2017 Article on page: 139-152 p. Languages : English (eng) Keywords: Sun-dried, smoked, consumer’s preference, market channels Abstract: Various dried fish products are available in Nepalese markets. The information on diversity and
marketing system of dried fish products in the country is scanty. Survey on dried fish was carried
out in 19 districts to elucidate the species diversity, market channels and consumer’s preference
of dried fish. Exotic species such as Harpodon nehereus, Penaeus spp., Stolephorus spp. imported
from several Asian countries shares approximately 70 percent of the dried fish market of the country.
The dried fish products available in the market are in the form of sun-dried, smoked, spicy instant
fish and fish pickle. Marketing system of dried fish varies for indigenous captured fish, cultured fish
and imported fish. Price of dried fish varied greatly being high in rainy season associated with short
supply and increased demand, and relatively low during winter months because of excess supply.
Survey findings indicated that consumer’s preference on dried fish species is different with their
different believes, traditional knowledge and eco-region. However, quality of dried fish available
in market is a concernLink for e-copy: https://afu.edu.np/sites/default/files/Diversity_and_marketing_of_dried_fish_pro [...]

Title : Effectiveness of different measures to control red bloom in carp ponds Material Type: printed text Authors: R. B. Mandal, Author ; S. Rai, Author ; M. K. Shrestha, Author ; D. K. Jha, Author ; N. P. Pandit, Author Publication Date: 2022 Article on page: 139-147 p. Languages : English (eng) Keywords: Euglena sanguinea, phytoplankton, mitigation, fish production Abstract: Red blooms caused by Euglena sanguinea (Ehrenberg, 1832) might cause severe depletion of dissolved oxygen
significantly in the pond. An experiment was conducted to assess the effects of measures for controlling E.
sanguinea on water quality, growth and yield of carp polyculture. The experiment included four treatments:
without mitigation measure (T1), skimming using net skimmer (T2), fertilization with urea and diammonium
phosphate (T3) and liming using agriculture lime (T4) with three replications. The experiment was carried out
for 120 days. The results showed that abundance of E. sanguinea was significantly lower (p diammonium phosphate treated ponds (270 ± 10 cells L-1) than control ponds (1650 ± 90 cells L-1). Water quality
parameter such as nitrite, total nitrogen and total phosphorus were significantly (p ponds (T1) than in treatment ponds. The net fish yield of rohu was significantly higher (0.19 ± 0.0 t ha-1) in T3
ponds than T2 ponds (0.07 ± 0.0 t ha-1). The present experiment effectively controlled abundance of E. sanguinea
but admixture of urea and diammonium phosphate application appeared to be better control measures because
dissolved oxygen content was at acceptable level in the ponds.Link for e-copy: https://afu.edu.np/sites/default/files/Effectiveness_of_different_measures_to_co [...]

Title : Effects of sunlight on the abundance of Euglenophyceae in earthen ponds | R. B. Mandal, S. Rai, M. K. Shrestha, D. K. Jha, and N. P. Pandit Material Type: printed text Authors: R. B. Mandal, Author ; S. Rai, Author ; M. K. Shrestha, Author ; D. K. Jha, Author ; N. P. Pandit, Author Publication Date: 2020 Article on page: 289-294 p. Languages : English (eng) Keywords: Red bloom, Euglena sanguinea, dynamics, light intensity, density Abstract: Algal red bloom in carp ponds has been a serious concern to farmers due its scum covering the entire pond surface area
during the day and disappearing in the evening. Thus it is important to examine the effects of sunlight on dynamics of red
bloom algae in ponds. An experiment was done with the use of three treatments, i) non-red bloom pond with sunlight, ii),
red bloom pond with sunlight, and iii) red bloom pond without sunlight; each treatment was replicated thrice. Density
of Euglenophyceae was assessed from two different water depths (10 cm and 50 cm) at three different times: morning,
afternoon, and evening. Results showed that Euglena sanguinea Ehrenberg, 1832 was dominant among euglenophytes and
it showed vertical and temporal migration with sunlight intensity. Density of E. sanguinea was significantly higher (p at 10 cm and lower (p Euglenophyceae and E. sanguinea by 69% and 80%, respectively. Maximum red bloom was observed during 12.00 to 13.00
hours, when light intensity was highest (1928 Lux to 1988 Lux). Appearance and disappearance of red bloom in the pond
was due to vertical migration of E. sanguinea with sunlight intensity.Link for e-copy: https://afu.edu.np/sites/default/files/Effects%20of%20sunlight%20on%20the%20abun [...]

Title : Performance of pangas (Pangasianodon hypophthalmus) under different densities in cages suspended in earthen pond Material Type: printed text Authors: S. N. Mehta, Author ; S. K. Wagle, Author ; M. K. Shrestha, Author Publication Date: 2018 Article on page: 217-224 p. Languages : English (eng) Keywords: Survival, gross yield, net yield, food conversion ratio, gross margin Abstract: Pangas (Pangasianodon hypophthalmus) is a highly productive freshwater fish species. An experiment
was done at the Regional Agriculture Research Station, Tarahara, Nepal to assess production and
economics of pangas at different stocking densities. The experiment was conducted in 12 nylon net
cages (1 cm mesh size and 25 m3 ), fixed in a 7000 m2 earthen pond for 90 days. The experiment was
set up using a completely randomized design (CRD) with 4 treatments, each replicated thrice. The
treatments were: 80000 fish/ha (T1 ), 100000 fish/ha (T2 ), 120000 fish/ha and 140000 fish/ha (T4
).
Pangas yearlings of average weight 81.2±0.7 g were stocked in each cage. Fish were fed with 30% CP
pellet feed twice daily @ 3% of body weight. At harvest, the average weight of fish in T1 , T2 , T3 and T4
were 547.2, 552.8, 531.0 and 537.5 g, respectively, with an average growth rate of 5.2, 5.2, 5.0 and 5.1
g/fish/day, respectively. There were no significant differences in average harvest weight and growth
rate of fish among treatments. The survival rate of pangas was significantly lowest in T4 (85.5%),
intermediate in T3 (91.3%) and highest in T1 (96.8%) and T2 (95.6%) (p gross yield of pangas in T1 , T2 , T3 and T4 were 42.4, 52.9, 58.2 and 64.4 t/ha/cycle, respectively. The
extrapolated gross yield was significantly higher in T3 and T4 than T1 (p highest in T3 (NRs. 10511.4/cage), intermediate in T2 (NRs. 8184.1/cage) and lowest in T4 (NRs.
5798.9/cage). Growth of this fish was higher at lower stocking densities, but highest production was
obtained at highest stocking density. Based on the results of this study we can conclude that stocking
density of pangas at 120000 fish/ha (T3 ) is more profitable.Link for e-copy: https://afu.edu.np/sites/default/files/Performance_of_pangas_%28Pangasianodon_hy [...]
