Bangladesh aquaculture – Sampling of farmed fish

The two photos show the sampling of farmed fish in a fish farm in Bangladesh. Sampling usually is done on monthly basis using simple gears such as cast net.  Sampling is carried out mainly for feed adjustment, and also for field observation on growth performance and health condition. Typically, a random sample of about 10-20 fish specimens is picked for sampling whereas individual length and weight is taken.

Note: We decided not to watermark the photos in order not to upset its clarity. However, we trust you will notify us if you wish to use a picture or more. This is expected and will be appreciated.
