Which one is more suitable either Pipette or Siphon to collect the faeces for measuring the digestibility parameters in the field of aquaculture?
Siphoning method is better because it collects all the faeces, even small partials. Depending on the volume of water and surface area of tank select diameter of siphon pipe. Pipette method may not collect all the faeces.
If you're doing beaker experiments, it's better to pipette. If you are doing tank experiments, you can siphon with an airline.
I totally agree with all the answers. I used Siphoning in one of my studies where I was collecting the same. It was very effective
I agree with the previous answers. if you are working with a tank environment, siphon is the best choice.
Dear Jannathulla,
I will recommend siphon as it is more effective compared to pipette.
I am not sure what you meant by the 'field'? To determine digestibility there is '1 must' the feces must be collected as soon as possible without breaking them. Siphon is convenient but will break feces. If you can design a conical tank which contains feces at the bottom or a plankton net covering the small cage, you can collect feces without using siphon or pipette. .
Dear Jannathullar
Using siphon is an applied method for feces collection but in this method the risk of mixing feces samples with food particles is probable which can affect the accuracy of measured parameter .So pipet collecting method is more accurate.
.
Siphoning method is more suitable to collect faeces from rearing tanks.
