DFO science itself says it's linked to availability of prey and the size of the herd.
All of those facts and figures come from DFO science. The alarming one is that late-term abortions are up 200%. A female harp seal, based on her body condition, can decide at any point through the gestation period to abort. That's what they're doing. Young females are aborting because they're underweight and they're shorter in body length.
The claw marks that we're seeing in the young of the year seals that we harvest are ever increasing. Again, our experts who do the grading in the plant believe it's because the mothers are trying to wean the pup off earlier, perhaps because they don't have enough body weight to wean them through the whole cycle.
