Title : SPW ANING }:lEHA VIOUR OF SAHAR, Tor putitora Material Type: printed text Authors: Basnyat, S.R., Author ; Lamsal, G.P., Author ; Agni Prasad Nepal, Author Pagination: 85-89 p. Languages : English (eng) Abstract: Sahar (!'or putitora) is an indigenous game fish species. Its population is declining in
natural water bodies of the country year by year because of overfishing, electrocutting,
poisoning and degradation of aquatic environment. Development of seed production
technology of this species is essential to restore its population abundance in natural
water resources and to erplore the possibility of high value commercial fish farming.
With this in view, broods of Sahar from the wild stock were reared in the earthen ponds
at Agriculture Research Station,Fish (ARSF), Trishuli since 1989 to study their spawning
behavior. Spawner had spawned on and off in the past. However, they did not spawn
every year. Spawners were checked weekly from March to May, the first spawning period
of Sahar. Altogether 11 spawners out of 20 with an average weight of 4. 0-6.0 kg were
subjected to hand stripping. Collectively 1,89,610 eggs were released by the spawners.
The average fecundity per kg body weight of the female was nearly 3100 eggs. Fertility
was excellent, over 90 per cent and hatchi bi lity remained at 81 per cent. Eggs, ranging
from 2.25 to 2.80 mm in diameter, hatched out 60-80 hours after incubation at
temperature ranging from 1~.5 to 20.4 °c.SPW ANING }:lEHA VIOUR OF SAHAR, Tor putitora [printed text] / Basnyat, S.R., Author ; Lamsal, G.P., Author ; Agni Prasad Nepal, Author . - [s.d.] . - 85-89 p.

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.
