| dc.description.abstract | The study was conducted to evaluate the comparison of production performance and economics of different carp
polyculture system in Gangni upazila under Meherpur district from July to November 2015. PRA tools such as
questionnaire based interview, cross check interview were used as primary data and also secondary information
were used to assess the performances in aquaculture activities. Forty pond fish farmers were purposively
selected, among which 7 (18.0%), 17 (42.0%), 3 (8.0%), 7 (18.0%) and 6 (15.0%) farmers were engaged with
carp-mola, carp-tilapia, carp-koi, carp-shing polyculture and carp fattening, respectively. The highest age were
32.0% and between 41 to 50 years and lowest 7.0% were 15-20 years. Majority of the farmers (97%) were
Muslims. Only 28.0% fish farmer took the aquaculture as their primary occupation. On the other hand, 57.0%
farmers were involved in agriculture, 8% business, 3.0% service holder and 5.0% were students. About 67.0%
of fish farmers lived in nuclear families and only 33.0% lived in joint family. Majority (35%) of the respondents
had semi -paka house, 32.0% had paka, 28.0% had tin-shed house and only 5.0% had kacha house. About 5.0%
had no education (illiterate), 18.0% can only sign, 33.0% had primary level, 22.0% had S.S.C. level, 18.0% had
H.S.C. level and 5.0% had bachelor level of education. Most of them (33.0%) had agricultural land 51-100
decimal. While 20.0% had 151-200 decimal, 17.0% had 101-150 decimal, 17.0% had 1-50 decimal, 13.0% had
up to 200 decimal and no farmer found without agricultural land. Only 23% were Small ponds (5-15 decimal),
about 35% were medium pond (16-25 decimal) and 40% farmers had large pond up to 25 decimal. About
65.0%, 23.0% and 12.0% farmers were having single, multiple and taken lease from others, respectively. Fish
farming was the primary income source for 60% and secondary for 40% farm owners. The minimum water
depths of 23% ponds were within 0.5-1.0 m, 53% ponds were within 1.00-1.5 m, 17% ponds were within 1.62.0
m
and
7%
ponds
were
up
to
2.0
m
respectively.
Most
of
the
farmers
used
fertilizer
in
their
fish
ponds
during
pond
preparation. Used lime at a dose of 1 kg/decimal, Urea 200g/decimal and TSP 100g/decimal. From the
survey it was found that 14 (35.0)% of the farmers applied supplementary/homemade feed prepared with ricebran
and
mustard
oil
cake,
17
(43.0%)
farmers
used
commercial
feed
and
9(22.0%)
farmers
were
depended
on
natural
feed. Average fish production of the farmers was 6274 kg/ha/yr. The highest average fish production
was 7904 kg/ha/yr which net income was BDT 2,42,060 ha/yr come from carp-tilapia polyculture system and
lowest average fish production was 5187 kg/ha/yr and net income was BDT 1,66,478 came from carp - koi polyculture
system. Annual income of fish farmer were varied from 61,000 to 150,000 form ha/yr BDT. It was
observed that the highest 48.0% fish farmers earned BDT 120,000-150,000 per year, which was higher than the
national average income BDT 99,864. From the present study it was found that out of five culture systems. The
average production of carp tilapia polyculture was higher and financial benefit came from the same technology
So it reveals that carp tilapia polyculture was better than other polyculture system. | en_US |
