. . .stocks of sturgeons are dangerously depleted, their native waters are now among the most polluted in the world, and they are extremely slow growing and slow maturing fish. If they are not to become entirely extinct drastic steps must be taken to limit consumption, as well as aggressive monitoring of environmental conditions, if the present very dire situation is not to become worse.
On a broader and even more depressing note stocks of fish are collapsing due to overfishing all over the world; stocks of oceangoing fish are predicted to drop as much as 90% over the next ten years if overfishing is not limited. Properly managed populations can recover- Chesapeake Bay crabs, and the codfish stocks are a case in point I believe- but the days of inexpensive and abundant stocks of wide varieties of fish are at an end and existing stocks must be carefully conserved if the species in question are to be harvested sustainably.
This, coupled with the presence of such high mercury levels in ocean going fish due to pollution that the FDA now recommends limiting consumption of ocean going fish to once a week or less, does not reflect very well on our custodianship of our resources, I feel bound to add. As my mother used to say, we can't have nice things, can we
