      abstract = {This study represented a survey report on present status  of management of carp brood fish. The survey was
conducted  with 40 hatcheries at Chacrha in Jessore from June to  November, 2012. Production of brood fish was
found to  depend on the combined interaction between feed and culture  technique. Some information showed that
brood fish  selection for induced breeding was done on the basis of  their experience. Pond preparation was carried
out properly  but stocking density of brood fish was quite high and water  quality was not maintained properly. Negative
selection of  brood fish was done in few hatcheries aiming at reducing  the cost for collecting or purchasing good
quality broods.  The sources of brood fish were mainly own and other sources  were Halda River, Padma River,
Govertment brood bank and  World Fish Center. Feed used for brood carp fish were  mainly rice bran (34.57%),
mustard oil cake (21.78%),  vitamin and mineral premix (0.8%), wheat flour (8.64%),  fish meal (8.64%) and soya bean
flour (10.37%), maize flour  (6.91%), rice ( 6.91%), di-calcium (1.73%), salt (0.34%)  and antioxidant (0.04%) .
Nutritional composition of feed  was mainly crude protein (30-40%), crude lipid (10-12%),  carbohydrate (20-30%).
Protein percentage of feed always  tried to keep 26% even though it was varied due to the  other feed ingredients.
Fertilizer such as Triple super  phosphate (0.73 kg/dec), urea (0.25 kg/dec), potash (1.5  kg/decl), cowdung (5.19
kg/dec), poultry offal (1.9 kg/dec)  and Murite of potash (0.13 kg/dec) were used. Scientific  brood and hatchery
management could be a good approach to  attain the main purpose of aquaculture.},
