| dc.description | Bangladesh is one of the world’s leading fish producing countries, where aquaculture
contributes 56.44 percent to total fish production. In last 10 years average growth
performance of this sector has increased by almost 5.43 percent and government is trying
to sustain this growth performance. The annual fish production of Bangladesh in 2016-17
has been recorded as 41.34 lakh MT against a demand of 40.50 lakh MT in 2016-17.
Over the last three decades, the fish production in Bangladesh has increased more than
five times (7.54 MT in 1983- 84 to 41.34 lakh MT in 2016-17) (DoF, 2017). This sector
is contributing significantly in food security through proving largest portion of quality
animal protein; almost 60 percent animal protein comes from fish. It contributes 3.61
percent to our national GDP and around one-fourth (24.41 percent) to the agricultural
GDP. Development in the aquaculture sector is one of the reasons for the increase in fish
production over the last few decades. | en_US |
| dc.description.abstract | The study was carried out from November 2017 to April 2018 in eight upazilas of
Dinajpur district to observe the present status of pabda (Ompok pabda) culture. A total of
60 farmers were selected randomly and interviewed to analyze the present status of
inputs used and production of the culture. According to the present study ages of most of
the farmers (48.3%) were between 36 and 50 years. Educational qualification found
highest at secondary level (45%). Formal training was received by most of the farmers
(71.67%). Average farm size was 0.14 hectare. Liming was done at 275.0 ± 3.91 kg/ha
during pond preparation. Both organic and inorganic fertilizers were used at a rate of
1900.0 ± 121.34 (cow dung), 60.0 ± 2.86 (urea) and 37.0 ± 2.08 (TSP). All the farmers
practiced polyculture of pabda. A total of 13 different fish species was found under
polyculture system in the study area. The highest stocking density (18000 ± 1866
Nos/ha) was found for pabda. Supplementary feeds were used by all the farmers and
most commonly used commercial feed for pabda were lily, aftab, mega, quality and
nourish feeds in pabda polyculture. The average production from three different
polyculture practice for pabda was found to be 3,176 ± 55 kg/ha (carp-pabda-gulsha),
3423± 88 kg/ha (carp-pabda-tilapia) and 3596 ± 65 kg/ha (carp-pabda). Overall, the
study indicated that the pabda polyculture is a promising option in the study area. | en_US |
