Overfished Species

We are fortunate to get both our fish as well as fish information from Jim Chambers. These days between health and environmental concerns it is complicated knowing which fish to eat.
Wanted to share a recent email he sent:

If you ever want to know which popular fish species are still in trouble (due to very low population levels) and have been listed by the federal government as “Overfished” in the annual report to Congress, see this link, then for the detailed list, choose FSSI and non FSSI Stocks.

The list is arranged by geographic region with the Northeast first, followed by the Southeast, then Gulf of Mexico, etc.

To understand how severely some populations have declined, look at the Bmsy ratio (next to far right column). A Bmsy of 1.00 means the population is “healthy” (as a fisheries biologist would say, it’s at its Maximum Sustainable Yield). When Bmsy gets down to 0.05, it is nearing extinction. Anything below 1.00 is officially “overfished,” which in itself is not too bad (as it can be rebuilt by controlling fishing pressure), but when it gets down below 0.50 things are getting very serious. Below 0.10, the population may never recover even if all fishing were to stop.

Seafood Guide
For a quick way to evaluate various seafood choices, I recommend using the Blue Ocean Institute’s Seafood Guide.

All the seafood Prime Seafood offers is from sustainably managed fisheries and they are free of dangerous contaminants. Did you know that the cheap farm-raised salmon which is readily available from seafood vendors contains cancer causing contaminants (PCBs and PAHs) in concentrations high enough that eating “just one 6 oz. meal a month poses a high risk” of cancer?

This time of year we are enjoying Jim’s King Salmon, Ivory King Salmon and Pacific Halibut.
