Title : Breeding Behaviour Of Sahar, Tor Putitora Material Type: printed text Authors: A. P. Nepal, Author ; Basnet, S.R., Author ; Lamsal, G.P., Author Pagination: 69-75 p. Languages : English (eng) Abstract: Broods of Sahar from the wild stock have been rearing in the earthen ponds at Fisheries
Research Station (FRS), Trishuli since 1989 to domesticate and study their spawning
behaviour. Spawner had spawned off and on in the past. However, they have spawned every
yearfor 3-4 years period. Some F, brood ofSahar produced at Station, and are the offspring of
wild collection brood also started to spawn since 2000.
As usual spawner fish were checked weekly from March to May, the early spawning period and
from October to November as the late spawning period of Sahar. Altogether 11 spawner with
an average weight of 4. 5 - 6. 0 kg in 1998/'99, 5 spawner with an average weight of 6. 6 - 7. 5 kg
in 19991'00 and 6 spawner in 2000/'01with an average weight of2.2- 4.3 kg was subjected to
hand stripping. The spawner released collectively 189610, 138950 and 92945 eggs in 1998/'99,
19991'00 and 2000/'01, respectively. The average fecundity (eggs per kg of body weight) of the
female was nearly 1000 to 6000 eggs. Fertility was good over 80% and hatchibility remained
more than 66 percent. Eggs, with average diameter 2. 0 to 2. 9 mm hatched out after 84 - 125
hours of total incubation period at temperature ranged from 19 to 2 2 oc.Breeding Behaviour Of Sahar, Tor Putitora [printed text] / A. P. Nepal, Author ; Basnet, S.R., Author ; Lamsal, G.P., Author . - [s.d.] . - 69-75 p.

Title : Study on growth performance and quality of meat in relation to nutrient level of rainbow trout fed on different protein level diets Material Type: printed text Authors: A. P. Nepal, Author ; Lamsal, G.P., Author ; Pradhan, N., Author ; Shrestha, S.K., Author ; Gurung, T.B., Author Pagination: 422-426 p. Languages : English (eng) Keywords: Growth performance, nutrient levels, quality meat, rainbow trout Abstract: A feeding trial was conducted to observe growth performance and the meat quality of rainbow trout using fry or initial average body weight of 3.9±0.5 to 4.3±0.6 g in first experiment and 9.4±0.6 and 9.6±0.5 g in second experiment. Fish were fed with 5 different types of diet containing 30%, 35%, 40%, 45% crude protein (CP) and control diet as existing feed (35% CP content) practiced in the Centre. All treatments were supplied with 10% soybean oil as the calorie source. The feed efficiency remained 44.8% to 53.5% in first experiment and 31.5% to 50.6% in second experiment showing highest efficiency, 53.5% in 30% CP containing diet in first experiment and 50.6% in 45% CP containing diet in second experiment………….

Title : VARIATION IN THE GROWTH OF RAINBOW TROUT FED UPON PELLET FEED WITH DIFFERENT PROPORTIONS OF SHRIMP MEAL Material Type: printed text Authors: Roy, N.K., Author ; A. P. Nepal, Author ; Basnyat, S.R., Author Pagination: 47-52 p. Languages : English (eng) Abstract: Animal protein is the most essential part of trout feed Shrimp is a good source of animal
protein to improve the quqlity of rainbow trout. However, shrimp is very expen~ive in the
local market. An alternate way to reduce the cost of trout feed is to use the shrimp meal
as low as possible. Feeding trial was conducted with jour group of diet with 70, 50, 30
and 10% shrimp powder with and without incorporating 10% soybean oil in each diet.
Rainbow trout jed upon the diets containing more than 50% shrimp powd_er resulted in
highest specific growth rate (2.0% per day}, feed efficiency more than 57% and survival
rate more than 98 percent. The 10% soybean oil mixed in diet with 30% shrimp powder
produced similar growth results of (;out as contrived in 50% inclusion of shrimp powder.
The production cost of trout with 30% shrimp powder added with 10% soybean oil was
estimated to be 15% less than the feed prepared with 50% inclusion level of shrimp
powder.VARIATION IN THE GROWTH OF RAINBOW TROUT FED UPON PELLET FEED WITH DIFFERENT PROPORTIONS OF SHRIMP MEAL [printed text] / Roy, N.K., Author ; A. P. Nepal, Author ; Basnyat, S.R., Author . - [s.d.] . - 47-52 p.
