The present study presents the results of a survey of a wide range of water bodies in Bangladesh to identify and describe Danio rerio habitat preferences. Field‐based experiments were conducted to determine the vertical distribution of D. rerio in the water column, together with five other fish spec...

The diet of zebrafish Danio rerio in Bangladesh consisted primarily of zooplankton and insects. Zebrafish was an annual species, with the main period of reproduction commencing just before the onset of the monsoon season. Growth rates varied with age and season, with the period of most rapid growth ...

In oviparous species a female's choice of oviposition site can have a significant impact on off-spring survival and thereby on reproductive fitness. Here we compare the spawning behaviour of domesticated zebrafish, Danio rerio, in the laboratory with wild fish in a field-based mesocosm study in Bang...

Hypothesis: Genes of the major histocompatibility complex (MHC) show high variability, which is believed to arise through pathogen-mediated selection. Organism: Zebrafish (Danio rerio) from seven independent natural populations. Location: Bangladesh: two sites in Khulna District in the River Ganges ...

The fish were sampled in two ponds in Khulna District (Ganges River drainage, south Bangladesh) and in five ponds in Mymensingh District (Brahmaputra River drainage, north Bangladesh). Almost all fish were infected, with total prevalence of 90 %. Majority of parasites found were in larval or immatur...
