Some characteristics of annual variation and spatial distribution of mean monthly minimum, mean monthly maximum and mean monthly temperature, annual variation and spatial distribution of mean monthly amplitude of temperature have been explained. The characteristics of changing pattern of temperature such as standard deviation, coefficient of variation, ratio between mean monthly maximum and mean monthly minimum temperatures have been studied. The run of the temperature in different stations for the years 1949-2008, the periodicity of mean annual temperature and mean decade deviations have been discussed. The integral curve of mean annual temperature for Dhaka has been prepared and explained. Regression analysis for mean monthly t...

The present study was emphasized on water quality parameters, feeding management and cost-benefit analysis. The water quality parameters temperature (0 C), pH, dissolved oxygen (DO) (mg/l) and transparency (cm) were measured by Celsius thermometer, pH meter, DO meter and secchi disk, respectively. The proximate composition of feed ingredients was determined by the Association of Analytical Chemists, 1980. Brood fishes were reared all year round in the brood ponds by supplying formulated feeds. Temperature was 19 o C-26°C in brood ponds and 18 o C-24 o C in hatching jars; pH was 6.93-7.87 in brood ponds and 6.79-7.54 in the hatching jars; dissolved oxygen was 4.8-6.3 mg/l in brood ponds and 4.8-6.7 mg/l in hatching jars; transparency was 14-18 cm in the brood ponds. The percentage of farm made feed was protein (27.76%), lipid (4.9%), CHO (18.62%), ash (11.31%), fiber (6.4%), moisture (31.01%).

The study period was February to June, 2015. Data were collected by using participatory rural appraisal (PRA) tools and personal observation. Net return was loss in 2013-2014 and the loss amount was BDT 254200. Cost benefit-ratio in 2013-2014 was 0.99. Major income (83.30%) of the fishermen community was drawn from the fishery activities of Bergobindapur baor. In 2014-2015, average income of fishermen was BDT 25250 during the fishing period. Within the household of fishermen community, the expenditure for food was 19%, clothing, 3%, childrens education, 19%, medical, 3%, dowry and religion, 33%, agriculture, 13% and others, such as business, accommodation, sanitation etc. 10%, which came from baor activities. The findings of this study indicated that Bergobindapur baor plays a vital role for the support of livelihood of fishermen and net profit from baor was not satisfactory. A long-term str...

Growth promoter was used in the experimental cultured farm. This growth enhancing aqua drugs was used in feeds of Tilapia. The results indicated that the growth promoter was the best treatment which significantly (P ≤ 0.05) increased of all growth performances (final weight, AWG, ADG and SGR), improved FCR, and best economic efficiency. It was clearly observed that there were distinct impacts of growth promoter on fish growth and production. In the present study water quality parameters were within the suitable range. Production of Tilapia i.e. 4650 kg/acre in promoter treated ponds whereas 3666 kg/acre in non treated ponds were recorded. Food conversion ratio (FCR) was 1.70 and 1.38 were found in the controlled and treated pond respectively. Clinically the treated fishes did not show any remarkable changes. There were no adverse effects on water quality criteria among all experimental treatments. It could be concluded that the inclusion of the commercial probiotic Rapid Grow at a level of 0.05mg Kg-1 diet at stocking density rate of 250 fish/ decimal of mono-sex Tilapia O. niloticus is useful to get the best fish performance with friendly effects on the environment.

Nine goats aged 8-10 months and weighing 7-8 kg was randomly allocated into 3 groups as A: treated with omentum, B: omentum plus antibiotic and C: control. Experimental wounds about 2.5 cm long and 0.5 cm deep was produced on each side of the midline at the lumber region in each goat. Omentum 2 cm long and 0.4 cm wide obtained from an abattoir were lodged between the wound edges and apposed with nylon thread by simple interrupted suture. Complete healing was obtained on 11, 13 and 19 days in groups B, A and C, respectively. Rectal temperature, heart and respiratory rates showed no significant (p>0.05) variation during the healing period. On histopathological studies, highest degree of inflammation was observed in group C till day 15, but on day 5 in groups A and B. The rates of fibrosis of collagen fibre, epithelialization and neo-vascularization were most inten...

The moisture content of raw FWME muscle was 74.45%, which was similar in boiled products but lower in grilled, fried, and microwaved products (p ≤ .05). The protein content in raw and cooked FWME muscles varied between 14.49% and 21.28%. There were found 20 different fatty acids in FWME muscle of which palmitic acid was the most abundant one with an amount of 26.51%–29.70% in raw and cooked FWME muscles. FWME muscle contained a substantial amount of ω‐3 polyunsaturated fatty acids, ranging from 7.54% to 13.7%. However, the thermal effects during cooking decreased the ω‐3 polyunsaturated fatty acid contents. There were seven essential and eight nonessential amino acids available in FWME muscle; among the essential amino acids, lysine content was the highest. Raw and cooked FWME were very rich ...
