A field trial was conducted to examine effects of substrates on yield of carp and SIS at Sukranagar Village, Chitwan district for 210 days in farmer’s pond. The experiment was designed with four treatments: T1 (carp only), T2 (carp+SIS), T3 (carp+substrate) and T4 (carp+SIS+substrate) with four replicates. Ponds were stocked with fingerlings of six carp species at a rate of 20,000 fish/ha and two Small indigenous fish species at a rate of 50,000 fish/ha in 1:1 ratio. Prior to stocking of fish, split bamboo mats were fixed in substrate ponds covering 2% of pond surface area to enhance periphyton growth. Carp were fed with dough of rice bran and mustard oil cake (1:1) at the rate of 3% BW daily while Grass carp was fed with grass and banana leaves at 50% BW. Growth and yield of Rohu and Common carp, combined net fish yield and gross margin were found higher (p<0.05) in carp ponds with substrate.

A field trial was carried out to test performance of four locally available substrates (split bamboo, whole bamboo, banana midrib and plastic bottle) for periphyton enhancement in farmer's ponds at Seri and Nandapur in Nawalparasi district for 7 months. Six carp species were stocked at 15000 fish/hectare and SIS at unrecorded densities. Carp was fed with rice bran and mustard oil cake at 1.5% BW while grass carp was fed with grass and banana leaves at 50% BW. There was no significant effect of substrates on growth and production of carp. Combined NFY was 19% higher in plastic bottle ponds than control ponds, while NFY of SIS was 50% higher in banana midrib ponds than control and other substrate ponds. FCR was significantly better (P<0.05) in split bamboo ponds than control ponds. Banana midrib decayed fast and was replaced 3-4 times during experimental period while plastic bottles performed better in terms of production and profit.

A study on the economic analysis of fish production using different feed types practiced in Dhanusha district was conducted in 2018. Out of 600 fish farmers, sixty fish farmers(10%) from the Fish Superzone region i.e. Janakpur sub-metropolitan city, Bideh municipality, Sahidnagar municipality, Kamala municipality, Hanspur municipality, Janaknandani rural municipality and Aaurahi  rural municipality, selected using simple random sampling, were surveyed using semi-structured questionnaire. The study revealed that locally formulated mash feed was commonly used feed type in which rice bran and mustard oil cake (RB+MOC) was the principle feed ingredient. 55% of the farmers used rice bran and mustard oil cake (RB+MOC), 20% used rice bran, mustard oil cake and soybean (RB+MOC+SOB), 10% used rice bran, mustard oil cake and fish meal (RB+MOC+FM) and 15% farmers mineral and vitamin (RB+MOC+MIN/VIT) in their feed formulation. The productivity of the fish production in feed type RB+MOC+SOB (3.41±1.02) was significantly higher than other feed type.  The total variable cost per ha (5.23±2.11) was found significantly(p<0.05) higher in feed type RB+MOC+SOB. Similarly, gross margin (4.44±2.74) received by farmers of feed type RB+MOC+SOB was also significantly high(p<0.05). The Benefit: Cost (B:C) ratio of the study area was found to be 1.69, high being of feed type RB+MOC+SOB(1.84) compared to others. The feed type RB+MOC+SOB is seen as a economically profitable one in the study area because of the high productivity, profit and B:C ratio. High feed cost was the major problem followed by the unavailability of feed. Fish farming can be a profitable business in Dhanusha with large opportunity to increase the fish production with increasing protein sources in the feed used. Farmers should be provided sufficient information, trainings and be encouraged to incorporate the protein rich sources like soybean and fish meal in the feed prepared to increase the productivity and ultimately return.

A field experiment was conducted at Regional Agricultural Research Station, Bangladesh Agricultural Research Institute (BARI), Ishwardi, Pabna during 2013-14 to find out an effective integrated management package for controlling root knot nematode, Meloidogyne incognita of pointed gourd. The following treatments were T1 = Spore suspension of T. harzanium added to around the roots of seedling, T2 = Dry neem leaves @100 g seedling-1, T3 = Furadan 5G @ 40 kg ha-1, T4 = Poultry litter @ 5 t ha-1, T5 = Mustard oil cake @ 800 kg ha-1, T6 = Furadan 5G + Dry neem leaves, T7 = Furadan 5G + Poultry litter, T8 = Furadan 5G + Mustard oil cake and T9 = Control were tested for their performance against the disease. Gall index ranged from 3.33-7.67. Significantly lower gall index (3.33) was recorded in treatment T7= Furadan 5G + Poultry litter and maximum gall index (7.67) was recorded in treatment T9= Control plot. The highest yield (24.97 t ha-1) was recorded in Furadan 5G + Poultry litter treated plot where are the lowest yield (7.53 t ha-1) was in Control plot. The incorporation of Poultry litter with Furadan 5G increased the efficiency of the treatment and gave satisfactory result to reduce root knot disease and to improve plant growth and yield of pointed gourd.

The Optimum harvest suitable for sustainable yield of tubificid worms without affecting the future yield for a period of 60 days was determined. The media ingredients used to culture the worms were 20% wheat bran, 30% soybean meal, 20% mustard oil cake, 20% cow dung and 10% sand. A harvest level of 50 mg/cm2 (maximum yield; 518.93 ± 14.36 mg/cm2) at ten days interval starting from 30 days of worms' inoculation was found suitable for sustainable yield in the later sampling durations. Results of this study have implications in increasing fish yield by producing reliable and sustainable yield of fish live foods tubificid worms.Key words: Tubificid worms; Live food; Optimum harvest; Sustainable yieldDOI: http://dx.doi.org/10.3329/dujbs.v20i1.8838Dhaka Univ.

A study was conducted to observe the breeding performance and nursery practices of the threatened indigenous fish species Labeo bata in Jessore (Longitude: 89°122 003 East; Latitude: 23°102 453 North), Bangladesh during 1998 to 2002. Eight trial doses of PG (Pituitary Gland) used for induced breeding of L. bata were 1.0mgPG/kg in the first dose, and 1.0 to 8.0mgPG/kg in second dose for female. On the other hand, five trial doses were administered for the male to identify the suitable single dose (1.5mgPG/kg) only. The best performance was obtained with 5.0mg of PG/kg body weight in the second dose for female of wild and successive three generations. The highest growth (lt.: 19.37mm and wt.: 57.67mg) and survivability (63.33%) of the fish fry was observed by using rice bran and mustard oil cake after 10 days of nursing.

In order to assess the effect of adding Dedhuwa (Esomus danricus), Mara (Amblyparyngodon mola) and Pothi (Puntius sophore) on Carp production, an experiment was carried out in farmers’ pond in Chitwan. The experiment included four treatments in triplicates: T1, (Carp: Silver carp, Hypophthalmychthys molitrix, Bighead carp, Aristichthys nobilis, Rohu, Labeo rohita and Mrigal, Cirrhinus mrigala), T2 (Carp+Dedhuwa), T3 (Carp+Mara), and T4 (Carp+Pothi). Fish were fed on dough of rice bran and mustard oil cake (1:1) at the rate of 3% of body weight. Results showed that Dedhuwa, Mara and Pothi did not differ significantly (P>0.05) in terms of production. Production of Silver carp and Bighead carp was found significantly higher (P<0.05) in T3 and T4 than control indicating no niche overlapping among these fish. Based on total production and profit T4 appeared to be best.DOI: http://dx.doi.org/10.3126/on.v9i1.5741
