It's a very good question.
We haven't really seen a lot of work in relation to seals. Most of the data we studied, as part of the Atlantic seal science task team, was dated. The offshore diet analysis was done prior to the mid-1990s. The inshore sampling, done predominantly in the same locations each year, takes place in the fall and winter months. For studying diet, we wouldn't find things like capelin or cod, because there's no fish inshore in Newfoundland and Labrador at that time.
In relation to populations growing, there were some numbers released last week on the grey seals. According to DFO, the population has slightly declined from the previous census. There is a census taking place this year, 2022, on the harp seal, so I would think that will work its way through DFO. Within a year or two, we should get some indication of the harp seal population.
