Public ISBD in Proceedings: 5th national workshop on livestock and fisheries research in Nepal 10-11 July 2002 / Rai, Ash Kumar     Title : Effect Of Different Organic Manures On Fish Production Material Type: printed text Authors: P. K. Sah, Author ; Joshi, P.L., Author Pagination: 65-68 p. Languages : English (eng) Abstract: A composite fish species including silver carp, bighead carp, common carp, grass carp, rohu, and mrigalwere stocked in twelve small earthen ponds, each of 500m2 in the ratio of 40: 20: 20: 10: 5: 5 to select the most effective type of manure for the production of fish yield. Each pond was stocked with fishes at the rate of 8000/ha. The experiment consisting of four treatments was started on 2057-6-1 and terminated on 2058-2-1, a period of 270 days. Each treatment had three replicates. The first, second, and third treatment ponds were manured by chicken droppings, pig manure and cattle manure@ 500 kglhalmonth on dry matter basis, respectively. The control pond was not provided with any manure. No feeding at all in any pond. Chicken manured ponds exhibited the highest production (3. 78 mt/ha) and this was followed by pig-manured ponds (2.49 mt/ha) and cattle manured ponds (2.14 mt/ha), respectively. The control pond had minimum production of 1.2 mt/ha. However, the experiment gave non-significant result. Fish survival in the treatment ponds remained nearly 80% and it was 75% in the control pond. No outbreak of disease occurred during the experimental period. in Proceedings: 5th national workshop on livestock and fisheries research in Nepal 10-11 July 2002 / Rai, Ash Kumar     Effect Of Different Organic Manures On Fish Production [printed text] / P.

Productivity Assessment in Polyculture Fish Farming Using Different Stocking Densities of Fingerlings / Thapa, A.B. ; P. K. Sah    

Public ISBD in Proceedings of the fourth national workshop on livestock and fisheries research in Nepal held from 24-26 April 2000 at Agricultural Research Station, Pakhribas / Neopane, Shreeram P.     Title : Productivity Assessment in Polyculture Fish Farming Using Different Stocking Densities of Fingerlings Material Type: printed text Authors: Thapa, A.B., Author ; P. K. Sah, Author Pagination: 39-44 p. Languages : English (eng) Abstract: Polyculture using two major cmp species of indigenous carp (Rohu, bhakur and naini) and exotic CGI]J (silver catp, bighead carp and grass carp) stocked in two stocking ratios (80:20) was carried out for 240 days ji·otn February 1988_ to October 1999 in two different stocking densities (5000 jingerlingslha and 7000 jingerlings/ha). Av. wt. offish 40-60 g size was stocked in earthen ponds (40 m x 10m). The common carp growth wps highest (4.5 glday and 4.1 glday) when stocked exotic catps as major species (,80%) in both stocking densities (7000 .fingerlingslha and 5000 jingerlingslha, respectively) followed by silver carp (~.4-3.6 glday) and bighead carp (2.5-3.5 glday) when stocked exotic carps as major species (80%). The growth rates of grass carp, rohu ·and naini were low (1.3-1. 7 glday) with slightly higher growth rate of bhakur (1.8-2.0 g/day) · showing no differences either in stocking ratios or stocking densities. The productivity obtained highest 4.2 Mtlha when stocked 5000 jingerlingslha using exotic carp as major species (80%) followed by 3.5 Mt/ha when stocked 7000 jinger/ingslha also using exotic carp as major catp. The lowest productivity was 2. 0 Mt/ha when stocked 5000 .fif!gerlings/ha using indigenous carp as major species (80%). The survival rates did not show much difference in all treatments and remained between 75-84%.
