| dc.description.abstract | A study was conducted to assess the existing technologies used by the fish farmers and its impact
on the fish production in Sylhet district from July, 2015 to December 2015. Three upazilas were
selected as experimental sites for the study namely Sylhet sadar, South surma and Golapganj
under Sylhet district. The data were collected using questionnaire interview and the data were
analyzed using statistical method followed SPSS software. In this study, in terms of input such as
cow-dung, urea, TSP, lime, rice barn and mustard oil cake, there is a highly significant difference
(P≤0.05) between semi-intensive culture technology compared to extensive in the farmer level.
In terms of cost item parameters such as fingerlings, feed, fertilizers, human labourers,
harvesting and marketing and miscellaneous there is a highly significant difference (P≤0.05)
between semi-intensive culture technology compared to extensive. This study reveals that there
are highly significant differences for all cost item parameters between extensive and semiintensive
technology
except
for
land
use
cost
(P≥0.05).
In
terms
of
production
output,
there
is
a
highly
significant difference (P≤0.05) between semi-intensive culture technology compared to
extensive. The mean values of the parameter net profit for extensive and semi-intensive culture
were 78330.00±19223.85 tk/ha/yr and 419470.00±368024.69 tk/ha/yr, respectively and there is a
highly significant difference (P≤0.05) between semi-intensive culture technology compared to
extensive. Therefore, we can assume that, semi-intensive technology has a highly positive impact
on fish production as well as more profitable for aquaculture in Sylhet district. Necessary
training on scientific fish culture and use of technologies, establishment of hatchery by GOs and
NGOs to ensure quality fingerlings and massive extension work can mitigate the problem related
to fish culture in the study area. | en_US |
