What International Seafood Sustainability Foundation Inc does
Mission
The international seafood sustainability foundation (issf)'s mission is to undertake science-based initiatives for the long-term conservation and sustainable use of tuna stock, reducing by-catch and promoting ecosystem health.
As stated on its FY2025 Form 990.
Programs
Science - issf is committed to improving the sustainability of global tuna stocks by developing and implementing verifiable science-based practices. The main areas of focus are tuna conservation, by-catch mitigation, illegal fishing, and capacity management. Guidance for research priorities and published technical papers are provided by issf's scientific advisory committee, which is comprised of the world's leading marine and fisheries scientists. This committee provides reference material for the board of directors to consider prior to taking action on sustainability efforts.

Issf also advocates to regional fisheries management organizations (rfmo's), which are international bodies comprised of countries that have interests in managing and conserving fish stocks in a particular region, to adopt and implement science-based measures to sustainably manage tuna stocks. In addition, issf works with tuna fishing fleets to build a greater commitment among fleet owners to science-based sustainable practices.

The organization over time
Each line starts at 100 in 2017, so what you read is the shape rather than the size: 150 means half as much again as 2017, 50 means half. The number beside each label in the key is where it ended. The shaded band is where the middle 50% of its peers' revenue would sit, given their growth.
Balance sheet
Total assets and total liabilities at each year end, in dollars. The largest one-year move in total assets was 2022 to 2023, from $1.2M to $1.8M (+46%).
How it's funded, over time
Each bar is one year's revenue split into where it came from, and every bar is the same height — these are shares, not amounts, so a year that raised twice as much looks the same size. Hover a bar for the split.

Who funds it, year by year
2017 → 2023: the base broadened from 1 funder to 2 funders, grant income rose $350k → $674k.
2 of 4 of your funders are donor-advised or pass-through sponsors (tagged DAF) — 23% of grant dollars received. That money is really individual donors directing a sponsor; the institutions to cultivate are the non-DAF funders.

In-state vs out-of-state, by year
Funder states come from each funder’s own filing. $1.1M arriving through sponsors registered in 2 states is excluded from the map and the split above: a sponsor holds money on a donor’s behalf, so its registered address would place those dollars somewhere no donor need ever have been. Trends are read to FY2023, the last fiscal year that has finished arriving. FY2024–FY2026 are still being filed and are shown unshaded; they do not move any figure on this page.
