Variability was studied among 246 foxtail millet [Setaria italica (L.) P. Beauv.] germplasm collected from different research stations and traditional farming villages of the Bangladesh. The collected genotypes were evaluated in the field at the Plant Genetic Resources Centre (PGRC), Bangladesh Agricultural Research Institute (BARI), Gazipur during winter 2013-2014 and 2014-2015. Qualitative variations were found in plant characters, leaf characters, inflorescence characters and seed characters. Erect and erect geniculate growth habit with non-pigmented, pigmented and deep purple plant was also exhibited among the accessions. Short Inflorescence lobes were present in the maximum number of accessions followed by long lobes but no inflorescence lobes and large and thick inflorescence lobe were present in five and one accession, respectively. Based on lobes compactness, medium was highest followed by loose, compact and spongy inflorescence lobe. Cylindrical, pyramidal, ovate to elliptic and ovate shaped with green and purple coloured inflorescence was present among the accessions. The majority of seed colour were white (58.1%), followed by black (13.4%) and others. Quantitative variations were observed among the accessions. Days to 50% flowering and days to mature seed harvest were 76 to 120 days and 116 to 157 days after sowing, respectively. Numbers of tiller per plant – ranged from 1 to 5.7. The highest coefficient of variation was found in number of tiller per plant (39.93 %) followed by peduncle length (35.59%). Days to seed harvest and days to 50% flowering showed the lowest (6.23% and 9.75%, respectively) coefficient of variation. The genotypes were grouped into ten clusters. The highest inter-cluster distance was observed between clusters VI and VII. Therefore, the genotypes belonging these clusters could be selected for future hybridization program.

A field experiment was undertaken to analyze the genetic divergence of maize inbreds under normal soil moisture condition with an aim to develop high yielding maize hybrids. The experiment was undertaken at Regional Agricultural Research station, Jamalpur during rabi season 2009-2010. The genotypes were grouped into eight clusters. It was observed that all inter cluster distances were larger than all intra-cluster distances. The highest inter cluster distance was observed between cluster II & VII followed by II & V, I & II, IV & VII and II & VI. The highest intra cluster distance noticed in cluster V and the lowest in cluster III. The mean value for yield, yield components and growth parameters were highest in cluster III but lowest value for yield in cluster VI and growth parameters in Cluster IV. The 100 grain weight, plant height, ear height and ASI (Anthesis Silking Interval) contributed considerably to total divergence. Results obtained from this study indicate that the genetically diverged genotypes in these distinct clusters could be used as parents in hybridization program for getting desirable hybrid(s).

A study was conducted to screen out the low temperature tolerant Boro rice seedlings during the period of November 2013 to January 2014 in research farm of Hajee Mohammad Danesh Science and Technology University (HSTU), Dinajpur, Bangladesh. The experimental area was facing rice production challenges due to climate change in the recent past. During cultivation period prevailing environmental temperature was below 15 oC. Seven rice cultivars (V1: BR-11; V2: BR-16; V3: BRRI dhan28; V4: BRRI dhan29; V5: BRRI dhan50; V6: BINA dhan7; and V7: Hybrid SL-8H) varieties were selected for the study. The seedling shoot length, shoot weight and root length, root weight, total biomass, and seed mortality rate were investigated. The highest shoot length was measured in V7 (9.56 cm at 33 DAS) and the highest percent shoot dry weight was found in V7 (34.63 g at 33 DAS). Again, the highest root length (4.09 cm) and root dry weight (10.070 g) were measured in V3 at 33 DAS. Most interestingly, V7 plants showed the best performing cultivars among the tested varieties responding dry biomass production. Conversely, the V3 cultivars showed very poor at low temperature at 12, 19, 26 DAS. Total biomass tends to decrease by low temperature environment. The highest mortality percentage was recorded in V1 and V5 (31.56 and 31.67%). The lowest seed germination percentage was found in V7 (11.33%). The cultivar (Hybrid SL-8H) having highest seed germination percentage is lower temperature stress tolerate than other cultivars.

Bactrocera cucurbitae and B. dorsalis are two fruits flies which cause significant damage to cucumber in Côte d’Ivoire. In perspective control, a monitoring of their populations was conducted during two periods (from April 2014 to March 2015 and from April 2015 to March 2016). Cucumber orchards were carried out in Dabou, South of Cote d’Ivoire. The catches of flies were made at twice a week to different phenological stages in traps made of yellow bowl. B. cucurbitae and B. dorsalis were collected during the four seasons of the year. These flies are predominant in crops during the fruit maturation stage. During the two study periods, the numbers of flies caught the rainy seasons were 3906 individuals for B. cucurbitae, 519 individuals for B. dorsalis and the rainy seasons, the numbers of flies were 1129 individuals for B. cucurbitae, 427 individuals for B. dorsalis. B. cucurbitae was more abundant than B. dorsalis on cucumber crop. Cucumber is preferred host of B. cucurbitae. The rainy seasons seem to be favorable to the development of these two flies.

This study evaluated shelf-life quality of two different temperature (60ºC and 80ºC) treated smoked Tilapia (Oreochromis niloticus), by analyzed their biochemical (proximate and chemical) composition and sensory evaluation during storage at refrigeration temperature (4°C). For this purpose a locally made improved smoking kiln was used. Treatment “A” was processed at 60ºC temperature for 2 hrs and “B” was processed at 80ºC temperature for 1.5 hrs under laboratory method. There was a general decline in sensory characteristics i.e. color, texture, odor, general appearance and mean of acceptability of fish- product during storage. The differences in the biochemical composition of the fresh and smoke-dried samples were statistically significant (p<0.05). Moisture (%) and TVB-N value (mgN/100gm) increased significantly whereas protein (%), lipid (%) and ash (%) content significantly decreased. The initial value of moisture, protein, lipid, ash, salt and TVB-N of freshly smoked Tilapia was 67.55%, 18.77%, 4.26%, 3.52%, 9.37%, 4.29% in treatment A and 72.05%, 17.64%, 4.24%, 4.36%, 5.31%, 5.24% in treatment B respectively. Between these two different temperature treated Smoked Tilapia, product prepared at 60°C treatment A became spoiled at 65 days whereas product prepared at 80°C treatment B smoke-dried product remain in good condition up to 45 days. This is because of the variation of temperature affects the moisture content of product. Due to high temperature (80 ºC) moisture content remain high and product’s shelf-life decrease and product comparatively soft. Whereas at 60ºC temperature product comparatively hard and had longer shelf-life. Therefore, considering all the quality parameters it showed that the hot smoked products prepared at 60ºC could be stored for two months after smoking retaining its unique taste and flavor.

Fish health management was one of the major areas where aqua farmers used a lot of antibiotics and disinfectants. Various pharmaceuticals companies were found to provide these drugs and chemicals with different trade names to meet the farmers demand. The study was carried out to know the present status of use of commercial aqua drugs and chemicals and their impact on fish health. Data were collected through questionnaire interview with fish farmers, drug sellers, personal contact and market survey from selected area in Mymensing district. Ten categories of drugs and chemicals were identified that have been using by fish farmers for different purposes. The categories included antibiotics, disinfectants, gas removal, oxygen supplier, vitamins and minerals, growth promoter, insect killer, algae killer, predator killer and pH balance. The companies included Fish Tech, Renata, Firstcare, ACI, ACME, Square, Samco, Novartis, Eon, Opsonin, Al Madina, Rals, Organic, Padma, Nature care, Advance and SK+F etc. Different types of fish diseases like epizootic ulcerative syndrome or EUS, tail and fin rot, red and white spot and dropsy in Shing (Heteropneustes fossilis), Koi (Anabas testudineus), Tilapia (Oreochromis nilotica) and Pangus (Pangasianodon hypophthalmus) were observed in the study area. Farmers used a lot of drugs and chemicals single or combined to overcome disease and health problems of their cultured fishes. Farmer got good recovery of disease after treating with drugs. During the field observation some problems were identified in using aqua-drugs which include poor understanding of farmers about the application of drugs, inadequate withdrawal period and some adverse effect on fish and human health.

The main purpose of the study was to determine the constraints experienced by the hatchery operators in the production of fish fry and to explore the relationships between eight selected characteristics of the hatchery operators and their constraints in the production of fish fry. Field work for the study was conducted in sadar Upazila under Mymensingh district. Data were collected from 70 selected hatchery operators from the study area. A structured personal interview schedule was used for collecting data during April to May 2014. Coefficient of correlation(r) was used to explore the relationships between the concerned variables. The study demonstrated five aspects of constraints: namely- rearing broodfish, breeding, rearing of fish fry, transportation of fish fry, capital constraints; were considered for measuring hatchery operators’ constraints in the production of fish fry. The selected characteristics of the hatchery operators were: age, educational qualification, household size, area under hatchery operation, knowledge on hatchery management, annual income, extension media contact and organizational participation. The observed constraints score of the hatchery operators ranged from 15 to 52 against the possible range of 0 to 60. The average constraints score was 32.32. Majority (72.86) of the hatchery operators were found to face medium constraints, while 12.86 percent faced low constraints and 14.28 percent faced high constraints in the production of fish fry. Constraints Facing Index (CFI) for all the 20 constraints items ranged from 8 to 176. Among the total 20 constraints under five aspects “lack of capital (CFI=176)” had the highest CFI and “unavailability of proper transport (CFI=8)” had the lowest. Among the eight characteristics of the hatchery operators, area under hatchery operation, knowledge on hatchery management, annual income and extension media contact showed significantly negative relationship with constraints. On the other hand, age, educational qualification, household size and organizational participation of the respondents did not show any significant relationship with their constraints.

The present work deals with the effect of predatory behaviour of Clarias batrachus (Linnaeus, 1758) on small carp species (Labeo rohita, Cirrhinus mrigala, Catla catla, Hypophthalmichthys molitrix etc.). Three experiments were conducted in the laboratory condition and two aquariums were used for each experiment. To observe the predatory effect of C. batrachus on small carp species each experiment were set with treatment-I and treatment-II. The supplementary feed was provided for the treatment-I and supplementary feed was not provided for treatment-II. Different size of C. batrachus such as fingerling, adult size and large size are used as predators in the experiment-1, experiment-2 and experiment-3 respectively and different stages of carp species fry such as hatchling, early fry, fry, advanced fry and fingerling are used as preys in each experiment. At the end of the study the result was found to be varied among the experiments. In experiment-1, the highest predation rate of fingerling of C. batrachus on hatchling and early fry were 95 and 92.5% respectively during treatment-II. The lowest predation rate was on fry (10, 20%), advanced fry (0, 0%) and fingerling (0, 0%) of carp species in both treatment-I and II respectively. The highest rate of predation by adult size of C. batrachus on hatchling, early fry and fry were 92.50, 97.50 and 80% respectively in treatment-II during experiment-2. The lowest predation rate was found on advanced fry (5, 10%) and fingerling (0, 0%) both treatment-I and II during experiment-2. In experiment-3, predation rate of large size of C. batrachus on hatching, early fry and fry were 85, 90 and 95% respectively in treatment-II, which were not provided supplementary feed whereas in case of providing supplementary feed 67.5, 60 and 65% predation rate were found. The lowest predation rate of large C. batrachus on fingerling of carp species was nil both treatment-I and II. In case of the study we observed that the supplied feed can justly keep down of predation rate of C. batrachus.

This study was conducted to evaluate the effects of different types of packaging on the shelf life of Rohu fish (Labeo rohita) fillets. Shelf life of the Rohu (Labeo rohita) fillets was studied at frozen temperature in deep fridge. Three types of packaging conditions were maintained those were non-pack, air-tight pack and vacuum pack conditions. The comparative study included determining of organoleptic, biochemical and bacteriological aspects. The organoleptic qualities of Rohu (Labeo rohita) fillets during ice and frozen storage were assessed on the basis of the sensory evaluation such as appearance, odour, texture and taste. In frozen storage, air-tight and vacuum packed fillets showed organoleptic scores in acceptable condition over 12 weeks of storage. The initial average pH value of fillets was 6.97 but the final pH values were 6.9, 6.83 and 6.78 in non-packed, air-tight and vacuum packed fillets, respectively in frozen storage. At the finishing day of the experiment the TVB-N values of non-packed, air-tight packed and vacuum packed fillets in frozen storage were 6.20, 5.34 and 5.20 mg/100g, respectively wherever the initial TVB-N values of non-packed, air-tight packed and vacuum packed fillets in frozen storage were 1.95, 1.97 and 1.96 mg/100g, respectively. Here, vacuum packed fillets showed more acceptability than non-packed and air-tight packed fillets. The initial peroxide values of non-packed, air-tight packed and vacuum packed fillets were 0.79, 0.78 and 0.79 m.eq./kg of oil, respectively in frozen storage. And the final peroxide values of non-packed, air-tight packed and vacuum packed fillets were 3.34, 2.25 and 1.84 m.eq./kg of oil, respectively after 12 weeks in frozen storage. The peroxide values were beyond the acceptable range in case of all types of packaging conditions after 12 weeks in frozen storage. The myofibrillar protein solubility gradually decreased in all types of packaging. The initial myofibrillar protein solubility values were 90.05, 90.18 and 90.12% in non-packed, air-tight packed and vacuum packed fillets, respectively in frozen storage. The final values were 71.50, 77.20 and 80.10% in non-packed, air-tight packed and vacuum packed fillets, respectively after 12 weeks of frozen storage. Initially the microbial load in non-packed, air-tight packed and vacuum packed fillets were 2.56×105, 2.67×105 and 2.59×105 CFU/g, respectively. Remarkable decrease in microbial count was found at 2 weeks of frozen storage, caused by the freezing effects. Finally they increased at the value of 8.2×103, 7.8×103 and 7.6×103 in non-packed, air-tight packed and vacuum packed fillets, respectively after 12 weeks of frozen storage. Finally, vacuum packaging gave most acceptance than air-tight packaging and obviously than without packaging.

The experiment was laid out in a RCB design with three replications seeds were sown in the field on 10 to 20 August 2015. Each entry was sown in 6 rows 4 m long plot with a spacing of 40 cm between rows. Spacing between two plots were 40 cm. The genotypes 86337 gave highest average yield (1206 kg ha-1) among the genotypes followed by BBLX-06002-10(1089 kg ha-1) and BBLX-07002-5 (1076 kg ha-1). It also produced highest seed yield in Joydebpur (1334 kg ha-1) across the locations. Out of six locations 86337 genotypes produced a good yield (1206 kg ha-1) on the other hand, the lowest average yield was obtained from the genotypes BBLX-07002-1 (1043 kg ha-1). The lines 86337, BBLX-06002-10, BBLX-07002-5 and 86337 gave greater seed yield which would be used for crop improvement breeding programs.

The experiment was undertaken to study the keeping quality of pasteurized milk at different temperatures (4°C, 7°C and 15°C. One hundred eight pasteurized milk samples were obtained from three different renowned milk company, out of which thirty six samples were collected from each of the three different renowned milk company as replication. All the samples were subjected to physical and microbiological examination. Total viable count and coliform count were done for the microbiological quality at different holding periods at day 0, 2, 5, 6, 8 and day 10 storage at 4°C, 7°C and 15°C. The results revealed that the average highest total viable count in the pasteurized milk was log 8.8325 at 15°C for 10 day storage and lowest value was log 4.0828 at 4°C for 0 day. Average highest coliform was log 2.8808 at 15°C for day 10 storage and lowest value was 0 at after 2nd days of storage at 4°C. It was concluded that pasteurized milk should be held at 4°C to achieve maximum shelf life. Further quality and shelf life of pasteurized milk depends on the raw milk quality, hygienic production of milk and improvement of storage facilities.

Cultivation of resistant or tolerant varieties is the easiest way to protect mustard crop from insect pests. Varietal screening for aphid resistance and stability of seed yield under aphid-infested and protected environment would help in identifying the tolerant varieties for aphid attack. The present study was conducted in the field of the Oilseed Research Centre, Bangladesh Agricultural Research Institute, Joydebpur, Gazipur, during Rabi season of 2014-2015. Twenty six entries of rapeseed and mustard were evaluated against mustard aphid (Lipaphis erysimi Kalt.). In three entries of Brassica rapa, namely BC-05115, BC-9921, BC-05117 (25.7-30.4 aphids/plant) and of Brassica juncea BJDH-01, BJDH-12 (6.6 -7.0 aphids/plant) comparatively less aphid infestation were found than the check and other entries. From the result of this experiment, it was observed that Brassica rapa entries were attacked by the highest number of aphid while Brassica juncea had the lowest aphid infestation.

The study was conducted in Ramna area of Dhaka city to know the present status of raw and processed meat. The overall condition of raw and processed products availability, price, preference, hygiene, production, sell etc were studied. Consumer’s concept and their preference for the product, idea about price, reason for preference, hygienic observation etc were observed. Fifty raw and processed meat sellers and 25 consumers were selected in the study area to collect data from them and according to their provided information the study came into a result. Mostly the young people are interested in the processed meat products. From the study it is obtained that, 69% of total meat supply are used in processed products and only 31% are used for household consumption. The consumer prefers burger mostly though it varies from shop to shop. Consumer mostly prefers the products for its flavor 28%. They usually comes in the processed shop weekly, they hardly comes daily. 60% consumers come in the shop weekly. The 50% consumers said that the hygienic conditions of the products are fair. The processed meat sellers preserve meat at 40C. The raw seller keeps the meat at normal temperature. The transportation system is based on rickshaw van and refrigerated covered van.
