In the fiscalyear 2014-2015, foreign income from the fisheries sector is 1.92%. About 11%inhabitants of our country directly or indirectly depend for their employmenton fisheries and aquaculture sectors (DoF, 2016). From 2000 to 2016, aquacultural volume enhanced from 7, 12,640 to 20, 60,408 MT, a much largerquantity than wild capture production (1.
023 million t) in 2016(Shamsuzzamanet al. 2017).The highlyproductive aquatic biodiversity of the Bangladesh has been associated to theworld’s one of the biggest wetlands (Bengal Delta) and three large riversystems (Ganges, Brahmaputra and Jamuna) that rise from the Himalayan Mountainsinto the Bay of Bengal.
Huge inland fisheries resources provide fish and otheraquatic flora and fauna to the millions of living people in the Delta (Hossain,2014).Leading Rangpurdistrict is a temper liable area. Water retaining capability of the pond islessening 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 ofBangladesh of which 60% contained water for 4-6 months while 40% absorbed for6-9 months in a year and even more in some areas.
Villagers normally, make useof these little water bodies for their domestic purposes while some are stillbanished due to their neglectful and vagrant mentality.Nilphamariregion is such an area where this culture strategy is the most wanted andadequate for all types and kinds of fish farmers for fish production andeconomic return. This analysis will be desired to give financial backup formarginal fish farmers and a source of quick return of money also. From theaquaculture point of view, those ponds have a high value for practicing fishculture including the species which have concise life cycle, hurried growth andrequire minimum inputs, such as Vietnamese koi (Anabas testudineus), Shing (Heteropneustesfossilis), genetically improved farmed tilapia (GIFT), Silver barb (Barbodes gonionotus), and Magur (Clarias batrachus), sharputi (Puntius sarana).To assure themaximum utilization of those ponds, above species were chosen for ensuring thehighest production. The demands for those fishes are owing to their taste andmedicinal values. The belief is that there are beneficial and medicinal criteriain those fishes which are healthful for patients and convalescents by Mookerjeeand Mazumder (1950). But absence of knowledge of proper culture methods andscarcity of good fish fry of suitor species at required time are found to besome of the chief constrains at up to date time to propagate the culturemethods of these species have yet not been optimize and figure out specially inNorthern region of Bangladesh.
In the past we were relayed upon forfish utilization only from the natural open water reserves but this dependencyis out of control due to gradual fragmentation of open water bodies as well asbooming our population density (Hoque etal. 2017). Since the expansion offish production from our beels, canals, lakes, river and estuaries are generallyto be complicated; we need to relay on aquaculture especially on pondaquaculture for enhancing of our population demand, employment generation andpoverty reduction of Bangladesh. Although the people of Bangladesh areincreasing geometrically but our reserves are not increasing in the same manner(Hoque et al.
