From the wikipedia article, sounds like not great, although some signs it _could_ recover in the near future if left alone -- which we are unlikely to do, because every time it starts to look like it might recover, we just overfish it again.
> In 2015, two reports on cod fishery recovery suggested stocks may have recovered somewhat.[56][2][57]
> A Canadian scientist reported that, cod were increasing in numbers, health, normalizing in maturity and behavior, and offered a promising estimate of increased biomass in particular areas.[2]
> A US report suggested that a failure to consider reduced resilience of cod populations due to increased mortality in warming surface water of the Gulf of Maine had led to overfishing despite regulation. Thus, overestimates of stock biomass due to generalization of local estimates and ignorance of environmental factors in the growth or recovery potential of a cod fishery would lead to mismanagement and further collapse of stocks, through further unsustainable quotas, as in the past.[58][59]
> In June 2018, the federal government reduced the cod quota, finding that the cod stocks had fallen again after just two years of fair catches.
While people are clearly happy about the return of this fish, seems clear there's a lot of uncertainty around what to do next and whether fishing for it is a good idea.
It's tough to talk about North Atlantic fisheries in aggregate. Some are reasonably healthy, others are still collapsed. Cod is just starting to rebound.
I wonder if fisheries recover? For example what’s the state of North Atlantic fisheries?
