In mentality. Nilphamari region is such an area

In the fiscal
year 2014-2015, foreign income from the fisheries sector is 1.92%. About 11%
inhabitants of our country directly or indirectly depend for their employment
on fisheries and aquaculture sectors (DoF, 2016). From 2000 to 2016, aqua
cultural volume enhanced from 7, 12,640 to 20, 60,408 MT, a much larger
quantity than wild capture production (1.023 million t) in 2016(Shamsuzzaman
et al. 2017).

The highly
productive aquatic biodiversity of the Bangladesh has been associated to the
world’s one of the biggest wetlands (Bengal Delta) and three large river
systems (Ganges, Brahmaputra and Jamuna) that rise from the Himalayan Mountains
into the Bay of Bengal. Huge inland fisheries resources provide fish and other
aquatic flora and fauna to the millions of living people in the Delta (Hossain,
2014).

Leading Rangpur
district is a temper liable area. Water retaining capability of the pond is
lessening day to day. As a consequence, the number of seasonal ponds (60%, BBS.
2000) is arising. About 55% ponds are seasonal in the northern districts of
Bangladesh of which 60% contained water for 4-6 months while 40% absorbed for
6-9 months in a year and even more in some areas. Villagers normally, make use
of these little water bodies for their domestic purposes while some are still
banished due to their neglectful and vagrant mentality.

Nilphamari
region is such an area where this culture strategy is the most wanted and
adequate for all types and kinds of fish farmers for fish production and
economic return. This analysis will be desired to give financial backup for
marginal fish farmers and a source of quick return of money also. From the
aquaculture point of view, those ponds have a high value for practicing fish
culture including the species which have concise life cycle, hurried growth and
require minimum inputs, such as Vietnamese koi (Anabas testudineus), Shing (Heteropneustes
fossilis), genetically improved farmed tilapia (GIFT), Silver barb (Barbodes gonionotus), and Magur (Clarias batrachus), sharputi (Puntius sarana).

To assure the
maximum utilization of those ponds, above species were chosen for ensuring the
highest production. The demands for those fishes are owing to their taste and
medicinal values. The belief is that there are beneficial and medicinal criteria
in those fishes which are healthful for patients and convalescents by Mookerjee
and Mazumder (1950). But absence of knowledge of proper culture methods and
scarcity of good fish fry of suitor species at required time are found to be
some of the chief constrains at up to date time to propagate the culture
methods of these species have yet not been optimize and figure out specially in
Northern region of Bangladesh.

 

In the past we were relayed upon for
fish utilization only from the natural open water reserves but this dependency
is out of control due to gradual fragmentation of open water bodies as well as
booming our population density (Hoque et
al.  2017). Since the expansion of
fish production from our beels, canals, lakes, river and estuaries are generally
to be complicated; we need to relay on aquaculture especially on pond
aquaculture for enhancing of our population demand, employment generation and
poverty reduction of Bangladesh. Although the people of Bangladesh are
increasing geometrically but our reserves are not increasing in the same manner
(Hoque et al. 2017).
