Hello Everyone,

It is very late- 22:00 on Monday evening. It’s been a beautiful, albeit very busy, day, so I hope this post is interesting but brief. It is all about fish!

This is the latest post (from Bart M) about the events that have unfolded at the Port Lincoln barge where the osprey nest of Mum and Dad – the place where our dear Ervie and Giliath hatched and who, thankfully, have thrived. Let’s hope that continues.

” 21 September 2026

What is happening at Port Lincoln?

Just like last year the parents have left the nest, with the eggs unhatched.

We are not 100% sure why, but we can offer plausible causes.

The main cause is that there is not enough fish brought to the nest by Dad. We’ve seen Mum fishing herself a couple of times the past weeks (since 8 September), which in itself is a sign that she’s is not getting enough fish.

On 19 September she leaves the barge, with the eggs being 26 and 23 days old.

So why is Dad not bringing enough fish?

Is it age related?

There is no evidence of that. Just a few weeks ago, when Mum was having her ‘affair’ with Ervie, he was able to bring lots of fish per day, convincing Mum he could do his job.

There is evidence of there not being enough fish in the bay: Fishermen in Port Lincoln are saying the fishing is so poor, they are leaving their boats out of the water. Also other nests are suffering, like the white tailed eagles nest. And we see Ervie and Giliath fishing further away on the GPS trackers.

The cause?

The past years the temperature of the water has been rising, and this leads to two things:

1) In 2025 there was a big bloom of algae, and a toxic one, killing thousands of fish and other marine wildlife and also this year there is a lot of algae blooming again.

2) Fish will head into colder, deeper, water, making it harder for osprey to catch them.

And when there is not enough fish, the instincts kick in.. stress levels rise and Mum abandons the eggs. Note she only laid two eggs in the first place, which is already an indicator.

She (and Dad) will probably incubate the eggs for a while.. also instinct: Eggs! Incubate!

But the eggs won’t be viable anymore.

Last year showed the embryos died just prior to Mum leaving them for a day. So even a couple of hours without incubation was enough.

Could the fish fairies help is a question in chat?

Of course, but that would take a lot of resource, both money to buy the fish, and people bringing the fish to the barge. And PLO would have to do that for a whole season, until even late in December. That is just too much to ask and not sustainable. Note that in 2024 only on 29 days fish were actually supplemented.

So is there nothing we can do?

Not for this season, and not for Mum and Dad on the barge.

But we can shout to the world and everyone around you that we as a people must take better care of our world. This is a sign we cannot ignore, and it’s not only here that it is happening. In a lot of places, all over the globe, Osprey and wildlife is suffering because of climate change.

And we can only hope nature in the Port Lincoln area will adept and recover, so next year there will be more fish.. and we can enjoy the sight of new little osprey on the nest.”

I was shocked this evening to find that the topic of Menhaden, the primary fish for many ospreys in the NE United States, was central to a post by a leading chef based in Paris!!!!!!! I have cut and paste what was said in Spilled Milk #499 by Andrew Zimmerman in :

The Choices We Make Are Killing Us

I am off to NYC today to attend UNGA81 for Climate Week, to learn, listen, share my experience and try to make a difference with all my United Nations, nonprofit and NGO partners. And I can’t shake this brilliant op-ed by Mark Robichaux in The Washington Post.

Robichaux is a former Wall Street Journal reporter, fisherman and author, which is an unusually useful combination for this subject. He understands both how to follow an institution and how to read the water. His piece is about Atlantic menhaden, an oily little fish most Americans have never heard of and almost none of us eat. Which is precisely why this matters so much.

Atlantic Menhaden: The Small Fish Holding Up the Ecosystem

Menhaden are forage fish. Striped bass eat them. Bluefish eat them. Tuna eat them. Whales eat them. Ospreys eat them. They are one of those unglamorous species upon which glamorous species depend.

Robichaux points out that researchers studying Chesapeake Bay ospreys found reproductive collapse in high-salinity areas where menhaden are an important food source. The researchers carefully stopped short of proving that commercial menhaden harvest caused the decline but made a superb case that reduced menhaden availability is a primary driver of poor reproductive performance.

Meanwhile, we keep removing staggering quantities of them. Ocean Harvesters, whose catch supplies Omega Protein’s Virginia reduction plant, harvested nearly 300 million pounds of menhaden in 2024. That’s about 70 percent of the Atlantic coast harvest. Much of this extraordinary biological resource is turned into fish meal and fish oil for aquaculture, livestock feed and supplements.

Think about the absurdity. We are removing one of the foundational foods of the Atlantic ecosystem so that we can grind it up and feed it to other animals. And increasingly, we learn that we don’t have to. We are literally devouring our own planet. Gobbling it up until nothing will be left.

Microalgae and the Alternatives We Already Have

Microalgae naturally produce the same long-chain omega-3 fatty acids, EPA and DHA, for which we prize fish oil. Algal oils are already commercially viable ingredients in aquaculture and research shows they can replace substantial amounts, sometimes all, of the fish oil in certain feeds without sacrificing growth or fish quality.

The remaining problems are principally economics, formulation and scale. Those are solvable human problems. We are really good at it.

That distinction matters because this isn’t really a story about menhaden. It’s about us. We have developed an astonishing habit of identifying damaging practices, developing alternatives and then continuing the damaging practices anyway.

That is an ideal definition of insanity.

I am so pleased that the plight of the ospreys and the need to protect our oceans, rivers, and lakes/lochs has been brought to the attention of such a diverse group of individuals. Hearings continue. Politicians need to be ‘buried’ by your letters and e-mails. Now is the time to speak up. Do not be shy. Write a heartfelt letter about your observations, nests that you loved that failed due to a lack of fish. Make it personal because this is personal – we all love our fish hawks. Just imagine how you would feel if Iris sat on her nest starving to death before you and you had done nothing? Again, now is the time to write to your politicians. Read Andrew Zimmerman’s blog closely – maybe you will want to sign up for his free blogs?? – it might give you some ideas for writing your own letter.

Here is another article. This is ‘Save the Bay’.

People who want to protect menhaden from industrial fishing by Omega Protein can write to environmental conservation groups, state legislators, and fisheries management commissions, campaigning for stricter catch limits.

Where to Write and Contact

• Save Menhaden Campaign: Visit Save Menhaden to sign petitions and contact local representatives.
• Chesapeake Bay Foundation (CBF): Write to the Chesapeake Bay Foundation to support conservation studies and tighter restrictions in Virginia waters. This is the article above that is ‘Save the Bay’.
• Atlantic States Marine Fisheries Commission (ASMFC): Submit comments directly to the commission responsible for managing Atlantic menhaden quotas.
• Virginia General Assembly: Write to local Virginia state delegates and lawmakers to urge legislative action on industrial reduction fishing in the Chesapeake Bay.

Thank you so much for being with us today. I will be back later in the week with our good news stories!

Take care everyone.

Thank you to everyone for their posts, their articles, and the will to save the fish for the Ospreys – Menhaden do not need to be chicken feed!!!!!!!!! Thank you also to Open Verse where I found the image of Menhaden!
