Genetic characterization of the base population of a breeding program is useful in monitoring changes in the genetic structure that might occur over generations. By using microsatellite DNA markers, we have analyzed the genetic population structure of the Jamuna, Padma and Halda river samples of Catla catla maintained in a Brood bank of the Department of Fisheries, Bangladesh. We detected a tot...

Genetic variation is a key component for improving a stock through selective breeding programs. Randomly amplified polymorphic DNA (RAPD) markers were used to assess genetic variation in three wild population of the catla carp (Catla catla Hamilton 1822) in the Halda, Jamuna and Padma rivers and one hatchery population in Bangladesh. Five decamer random primers were used to amplify RAPD markers...

Halda is a 98 km-long tidal freshwater river of Bangladesh, which has unique feature since it the only natural breeding ground and sole source fertilized eggs Indian Major Carps globally. The present study firstly summarizes impact environmental stressors to understand phytoplankton abundance, community, their diversity in River, Bangladesh. Environmental data as seasons (Winter, Monsoon), wate...
