Estimating Foetal Growth Rate from Cross‐Sectional Samples of Field Data with Application to Pilot‐Whales

| Summary: | A method is developed for estimating foetal growth rate from cross‐sectional samples of field data, using a model for the distribution of foetal lengths at various times of the year to allow for a seasonal pattern in conception rates. The method is applied to data from catches of pilot‐whales off the Faroes taken over a 3‐year period. This indirect approach provides an estimate of gestation length which is shorter than previously suggested. |
