Tubificid worms are aquatic invertebrates, belonging to the class Oligochaeta and family Tubificidae, used as an important live food for fishes. The study was conducted to culture Tubificid worms under running water in order to develop a suitable culture media and an optimum duration of media inoculation for culturing Tubificid worms. The worms were cultured under two experiments in cemented culvert system (160×25×10 cm3) for 90 days. In the first experiment the worms were cultured in three different media designated as treatment-I, treatment-II and treatment-III. The highest yield (503.39±22.98 mg cm-2) was found at 70th day of culture duration in the culture media containing a mixture of 35% mustard oil cake, 20% wheat bran, 25% cow-dung and 20% fine sand (treatment-III). Only 1.99 kg media ingredients valued BDT 29.85 were needed to yield 1 kg worms. In the second experiment, the worms were cultured at three different intervals of media inoculation i.e., 6, 10 and 15 days interval designated as treatment-I, treatment-II and treatment-III respectively using the media found best in the first experiment. Inoculation of media at 10 days interval showed significantly (P<0.01) higher production (488.94±5.60 mg cm-2).DOI: http://dx.doi.org/10.3329/jbau.v10i2.14925 J. Bangladesh Agril.

The effects of three wetting media (cattle blood, rice gruel and subsurface clean water) of the culture media ingredients (a mixture of mustard oil cake, soybean meal and mud) on the yield and amino acid composition of tubificid worms cultured on a pilot scale in a fish farm for 42 days were evaluated. The worm yields were in the order: cattle blood wetted media (683.68 ± 3.86 mg/cm2), rice gruel (615.63 ± 3.66 mg/cm2), water (584. 38 ± 1.41 mg/cm2). Lysine, arginine and leucine were the most prevalent of the eight essential amino acids in worms cultured in the media wetted in cattle blood medium. The results suggested that a mixture of 40% mustard oil cake, 30% soybean meal and 30% mud can be used for the commercial culture of tubificid worms as live fish food. The tubificid worms showed high level of amino acids suitable for fish that require a high content of dietary amino acids. Asiat. Soc. Bangladesh, Sci. 45(2): 229-239, December 2019

Investigation was carried out from June to August 2009. A total of 40 fish farmers were selected from northwest two upazila namely Debigonj (n=20) and Boda (n=20) where both men and women were targeted. Focus group discussion (FGD) and cross-check interview were conducted to get an overview on carp farming. From 1991-1995, 1996-2000 and after 2000; 17.5%, 45% and 37.5% of fish farmers started carp farming respectively. Average 77.5% of farmers acquired training from NFEP project while 10% of them from government officials. There were 55% seasonal and 45% perennial ponds with average pond size 0.09 ha. After phase out of NFEP project, 92.5% of fish farmers followed polyculture systems, while only 7.5% of them followed monoculture ones. Farmers did not use any lime, organic and inorganic fertilizers in their ponds before association with NFEP project. They used lime, cow dung, urea and T.S.P during pond preparation at the rate of 247, 2562.68, 46.36 and 27.29 kg.ha-1.y-1 respectively where stocking density at the rate of 10,775 fry.ha-1 after phase out of the project. Feeding was at the rate of 3-5% body weight.fish-1.day-1. Rice bran, wheat bran and mustard oil cake used at the rate of 1920, 220 and 110 kg.ha-1.y-1 respectively by 85% of fish farmers but 15% of them did not used any feed. Before NFEP project, average pond production was 408.55 kg.ha-1 but after phase out the project, fish production was 2,861.08 kg.ha-1. Peak culture and harvesting period lied from April to December and from November to January. Average 92.5% of farmers improved their livelihood through carp farming. Fish farming was affected due to low water depth and drought conditions. Keywords: NFEP; Fish farming parameters; Pond production; Livelihood approach DOI: 10.3329/jbau.v8i2.7942 J. Bangladesh Agril.

The present research work was conducted to develop a balanced ration for crossbred high yielding calves in farm condition. For this purpose, seventy days long feeding trial was conducted with nine crossbred female calves having nearly similar body weight and age. Nine crossbred calves were equally divided into three groups such as T1 (1 kg concentrate mixture of crushed maize, wheat bran, mustard oil cake, molasses, DCP and salt at a ratio of 25:45:22:5:1:2, respectively), T2 (1 kg concentrate mixture of crushed maize, wheat bran, soybean cake, molasses, DCP and salt at a ratio of 27:45:20:5:1:2, respectively) and T3 (Wheat bran, rice polish, mustard oil cake, DCP, Salt were supplied according to BAU routine farm feeding at a ratio of 65:18:14:1:2, respectively). All calves were supplied with ad libitum green grasses (German and Para) and fresh clean drinking water. From the research finding, it was observed that the average total dry matter intake, total body weight gain, body length gain and heart girth gain were in T1 (2.68a±0.000 kg, 2.51a±0.21 kg, 1.83a±0.12 cm, 1.29a±0.07 cm, respectively) and T2 (2.65a±0.001 kg, 2.55a±0.21 kg, 1.67a±0.12 cm, 1.25a±0.07 cm, respectively) groups significantly (p<0.05) higher than that of the T3 (2.34b±0.002 kg, 0.96b±0.21 kg, 0.81b±0.12 cm, 0.64b±0.07 cm, respectively) group. The result showed that the body weight gain of T2 group was higher by supplementation of balanced ration. Therefore, the feed supplementation of crushed maize, wheat bran, soybean cake, molasses, DCP and salt at a ratio of 27:45:20:5:1:2, respectively should be supplied to crossbred calves for the future development of dairy herd replacement stock for profitable dairy business.

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.

The study was conducted on the fish farmer, which was situated at Chaugachha Upazila, Jashore, from October 2015 to April 2016. Data were collected using participatory rural appraisal (PRA) tools and personal observation. About 62% of the farmers have ponds of single, and 38% have multiple ownership. The homestead and commercial ponds were 79% and 21%, respectively. About 100% farmer carried out poly-culture fish farming though they did not know poly-culture just culture of various fishes. About 98% of the farmers control aquatic weeds manually. For controlling undesirable species, most of them (95.74%) used the netting method. Liming used 185. 3-247 kg/ha and organic fertilizer, mainly cow dung used 741-1235 kg/ha. Average stocking density was found to be 12326 fry/ha. 91.5% of the farmers applied supplementary feed, such as both rice-bran and mustard oil-cake. The peak harvesting period was found from December to January. In this season, around 65% of the stocked fishes were reported to harvest, and the rest of the fish (35%) was harvested during another season.

A field experiment was conducted at the Bangladesh Rice Research Institute, Gazipur during 2013 to study the potential of different organic materials in integrated plant nutrition system (IPNS) and soil test based (STB) inorganic fertilizer on the growth, nutrient uptake and yield of rice (<i>Oryza sativa</i> L.): variety BRRI dhan29. Five treatments were laid out in a randomized complete block design with four replications. The treatments were: (1) soil test based inorganic fertilizer (NPKS @ 138-7-80-3 kg ha-1), (2) cow dung (3 t ha-1), (3) poultry manure (2 t ha-1), (4) mustard oil cake (2 t ha-1) and (5) control. Organic fertilizers were applied on dry weight basis. Inorganic fertilizers were applied along with poultry manure (PM), cow dung (CD) and mustard oil cake (MOC) as IPNS. Soil test based STB fertilizer and PM in IPNS provided maximum grain yield of rice (6.11 t ha-1). Maximum plant height and tiller numbers were found in MOC treatment, while the numbers of filled grains were higher in STB fertilizer and PM treated plots. The application of different organic sources as IPNS significantly influenced the N, P, K and S uptake in rice. However, the highest N, P, K and S uptake were found in the PM treatment. The benefit cost ratio of different treatments followed the order of STB>PM>CD>Control>MOC. Considering yield potential and BCR, STB fertilizer and PM treatments were found economically profitable. However, from environmental point of view and sustainable management of soil health and crop productivity, application of PM and CD in rice-rice cropping system is recommended for rice cultivation.The Agriculturists 2016; 14(1) 33-42

Indian Major Carp

A study on the effects of artificial feeds on growth and production of fishes along with some limnological conditions were conducted in polyculture system. Species of Indian major carp (Cirrhinus mrigala) and exotic fishes (Hypophthalmicthys molitrix and Oreochromis niloticus) were stocked in six ponds under two treatments, each with three replications. Stocking rate in both treatments was 100 fish per decimal at the ratio of silver carp: tilapia: mrigal = 2: 2: 1. Fertilization and artificial feeds were given in Ttreatment 1 (T1) and only fertilization was done in Treatment 2 (T2). Wheat bran, rice bran and soybean meal were given daily as artificial feed in T1 in the ratio of wheat bran: rice bran: soybean meal = 2: 2: 1 (by wt). Urea, T.S.P and cow dung were applied fortnightly at the rate of 60 g deci-1, 90 g deci-1 and 2 kg deci-1 respectively. Water temperature, transparency, pH, dissolved oxygen, free CO2, total alkalinity, PO4-P and NO3-N were determined fortnightly and phytoplankton and zooplankton were studied fortnightly. These limnological conditions were more or less similar in the ponds under two treatments and were within suitable ranges. Calculated gross and net yields of fish were 16.56 and 12.48 ton ha-1 respectively in case of fertilization and artificial feeding application (T1) and 9.99 and 5.91 ton ha-1 respectively in case of only fertilization (T2). Application of artificial feed in T1 significantly increased the growth and production of fish more than two times which indicates that artificial feeding in polyculture is very useful for increasing fish production.
