The best fit of a model to Discovery mark returns according to stock structure hypothesis IV for NA fin whales is obtained when the estimate of the abundance in the EG area is only a fraction of the WI area abundance (0.15). When the ratio of the EG to WI abundance is bound within the range observed in sighting surveys (1.43, std. 0.10) the 5% mixing of the breeding stocks assumed in these areas under the hypothesis is significantly too low and even when the abundance ratio is as low as 0.64… CONTINUE READING
