Precautions for capture-recapture methods

• Organisms mix uniformly within the population.
• Sufficient time elapsed between capture and recapture to allow uniform mixing.
• The population is closed, i.e. there is no emigration and immigration to the specified area.
• Making does not hinder movement of organism or make the conspicuous to predators.
• Marking are permanent.
• The mark does not harm the animal
• There must be no mortality between the mark and recapture times.
• The mark doses do not make an animal more/less easily captured
