The mark-release-recapture method involves capturing, marking, and releasing a sample of species, followed by a second capture to estimate total population using the formula (No. caught in 1st sample x No. caught in 2nd sample) / (Number marked in 2nd sample).
Metoda de marcare-eliberare-recapture implică capturarea, marcarea și eliberarea unui eșantion de specii, urmată de o a doua capturare pentru a estima populația totală folosind formula (Nr. prinși în prima probă x Nr. prinși în a doua probă) / (Nr. marcați în proba a doua).
| Front | Describe the mark-release-recapture method |
|---|---|
| Back | 1. capture a sample of species using an appropriate technique e.g. pitfall traps 2. mark them 3. release them back into their habitat 4. take a second sample from the same population after a certain time frame 5. count how many of the second samples are marked. EQUATION: Total Population Size= (No. caught in 1st sample x No. caught in 2nd sample)/ (Number marked in 2nd sample) |
