Wild Ocean Blue

This week an extract of my book Poseidon’s Steed was published in the Guardian, and the book is now available to buy in Europe from various online booksellers. So I thought it was time I blogged about my favourite fish.

One of the questions I get asked a lot is ‘Are seahorses endangered?’. And my answer is, sadly, yes they are.

Seahorses around the world are not only taken from the oceans (both deliberately and accidentally) in scarily high numbers, but they also suffer from the breakdown of their fragile habitats – especially coral reefs, seagrasses and mangroves.

So, what can we do about it? Well, here are my top ten tips for doing your bit to save the seahorses:

1. Don’t buy dead seahorses

This may sound a little odd. Why would you want a dead seahorse?

Because they live inside a coat of bony plates – which take the place of a more conventional suit of fishy scales – seahorses maintain much of their delicate and intricate shape after they die.

Obviously, it’s not quite the same, but much of the seahorses’ beauty lives on after death and there is something to be said for having your very own magical seahorse sitting on your desk (I must admit I have one on my desk, in a little cardboard jewelry box, given to me by a friend who’d had it for years – it must be a long time dead).

But don’t forget it is just the dead body of a fish that once led a quiet, gentle life on the sea floor.

Picking up a dead seahorse from the beach isn’t so bad. But the ones on sale in seaside souvenir shops will almost certainly have been taken live from the sea. So please, don’t buy them. The seahorses will thank you.

2. Make sure your pets were born on a farm

Following the publication of an extract of my book in the Guardian, a few readers have commented that keeping endangered seahorses might not be such a good idea. Have a read of chapter 5 of the book and you’ll find details of modern seahorse farms where seahorses are being bred for the aquarium trade.

So these days there is no excuse. Anyone who wants to keep these cute animals at home can do so without taking them from a wild.

In the book I also go through some of the pros and cons of keeping seahorses: for you, for seahorses, and for the environment. It’s not up to me to say if people should or shouldn’t keep seahorses – although I can see how lovely it would be to have live, beautiful seahorses in my life every day.

But if you want to keep them, make sure you go to reputable suppliers. Or check out online forums: home aquarists are often giving away spare baby seahorses that were born in their tanks. And this doesn’t just apply to seahorses; always choose captive bred not wild critters for your tank.

3. Don’t buy seahorse medicines

Again, this might sound odd.

Especially to anyone who isn’t familiar with the popular practice in various countries of using seahorses as an ingredient in traditional medicines.

Traditional Chinese medicine texts dating back 500 years prescribed seahorses for all sorts of medical conditions from broken bones and bed wetting, to skin rashes and even a flagging libido. Global demand for seahorse medicines is a driving force behind a growing market in seahorses taken from the sea – at least 25 million of them every year.

Especially worrying is the growing popularity of pre-packaged, off-the-shelf seahorse medicines that use weeny, dark-coloured seahorses that traditional Chinese medicine doctors normally don’t bother with. This means that now any seahorse, no matter what size or colour, can now be used in traditional medicines.

So, if you do use traditional medicines and can afford to buy seahorses (they aren’t cheap), then think about engaging your compassion for the natural world and choose an alternative that doesn’t include endangered species. Because there are lots of alternatives.

4. Protect the seahorses’ world

All sorts of human activities threaten the shallow coastal habitats that seahorses call home including coral reefs, seagrass meadows, mangroves, and estuaries. The list of problems is long and growing and includes pollution, habitat destruction, climate change, and ocean acidification.

And these are all things to worry about and take action over. Especially important is the creation of many more marine reserves or marine protected areas or marine parks or whatever you want to call them. Essentially these are places where the destructive influence of humankind is minimised, by banning fishing, extraction, direct input of pollutants and so on. Some strict marine reserves ban people altogether.

There are obvioulsy problems that do not respect the boundaries of marine parks. But we know that protected habitats on the whole are healthier and can cope better when more insidious problems like climate change come along.

Currently less than 1% of the oceans are offered protection from human activities. That number needs to go up – a lot.

You may not have the power to set up your own marine reserve (who does?) but public support of local, regional, national and international campaigns to protect the oceans is vital for action.

5. Stamp out destructive fishing

A major threat to seahorses comes from trawl boats that plough through their habitat. Shrimp trawl boats don’t only catch shrimp but they also scrape up millions of seahorses every year (most seahorses made into traditional medicines are picked out of trawl nets), devastating their fragile habitats in the process. This insensitive, unselective form of fishing has to stop.

Do your bit by not buying fish that were caught in trawlers. How do you know, you cry? Well, you can ask. More and more these days, supermarkets and restaurants are giving customers information about how their fish is caught. If they don’t say and won’t tell you, then don’t buy.

6. Take a stand against climate change

We may be releasing carbon dioxide into the atmosphere above our heads, but an awful lot of it ends up dissolved in the oceans where it’s already starting to wreak a particular brand of marine catastrophe. The oceans are becoming more acidic. And the seahorses – along with so many other marine creatures – are going to get hit hard, mainly because lots of them live in habitats that may soon be gone: coral reefs.

So don’t ignore the goings on in Copenhagan next month, because this really matters. Especially if you like the idea of a world with seahorses and coral reefs and other beautiful extraordinary wildlife.

And we can all do our bit to help. Switch off lights, turn down thermostats, insulate your house, recycle, drive less, fly less, ride your bike more. Get involved in campaigns like 350.org. And think of the seahorses while you do it.

7. Go see the seahorses

Aquariums around the world are home to thousands of seahorses and more of them than ever are bred in captivity and not taken from the wild (many aquariums swap baby seahorses when they have too many, which is often the case for the seahorses species that breed happily in tanks).

Stop for a few minutes and watch the seahorses doing their seahorse thing, and let your thoughts wander off. When they come back, you’ll have your own personal seahorse moment to carry with you and remind you about these amazing creatures and the wild world they live in.

And have a read of the information boards at the aquarium. You never know what you might learn about the world of seahorses.

There’s a great new Secret Lives of Seahorses exhibit at the Monterey Bay Aquarium. But fear not, if you aren’t in California there are seahorse exhibitions all over the place.

8. Go dive for seahorses

If you are an addict of the underwater world like me, then there are heaps of places to go see a seahorse. Well, you can try anyway: they are extremely tricky to spot, with their cunning camouflage and shy nature.

Plus they are naturally rare creatures. You’ll not spot a big herd of them galloping by, but maybe – if you’re lucky – you might catch sight of a solitary seahorse grasping onto a blade of seagrass or coral branch. (Although, a friend of mine has just been diving in Indonesia and swears she saw a sea fan covered in dozens of pygmy seahorses. I’m not sure if she wasn’t just suffering from a case of nitrogen narcosis).

And you don’t have to venture to the tropics to see seahorses. Contrary to popular belief, seahorses inhabit shallow seas along virtually every coastline, tropical and temperate (but they don’t like really cold, icy waters, so don’t bother looking there).

A few weeks ago, I saw my first British seahorse off the beach at Studland in Dorset. Yes, that’s right. A British seahorse. There are two species on our fare but chilly shores.

Divers can play an important role in proving that a seahorse is worth more in the water than out. So, go out and support dive operations that care about their local seahorses.

And if you do spy a seahorse, try not to hassle it, poke it, prod it, or blind it with camera flash.

In this picture I am holding onto Troy (or rather, he is holding on to me), but I must point out, I was diving with a licensed seahorse handler (the UK species are now protected). We were conducting a survey, taking down this guy’s vital statistics, and stopped just quickly for an unmissable photo opportunity!

9. Send in your seahorse sightings

Do your bit for seahorse research by getting involved with local seahorse spotting projects. The British Seahorse Survey collects reports of seahorse sightings from across the British Isles – and that goes for live seahorses in the water and dead seahorses too.

10. Spread the seahorse love

And finally… (as they say on the news)

I recently discovered these gorgeous cuddly seahorses made from recycled materials by a brilliant artist/designer snaulkter.

They are simply the most adorable – and accurate – depictions of seahorse in fabric that I’ve seen (and trust me, over my years of being a seahorse fanatic friends have given me virtually every beanie baby and cuddly seahorse ever made!). And I love that they are made from reused fabrics. Perfect!

So go get the kids hooked on seahorses, or indulge a grown up’s passion. Each seahorse is a unique critter, and each one is beautiful. Go see for yourself…

So… there you have my top 10 suggestions of how to help save seahorses. I’d love to hear you thoughts of any other things we can do.

If you’ve been watching my tweets lately, you’ll probably already have noticed I like to link to ocean stories from around the web.

So I thought I’d give you some thoughts on my favourite ocean tweets from the past week.

For starters, it seemed to be a week of great seahorse fecundity with the announcement of baby seahorses being born in two English aquariums. We had spotted or yellow seahorses in Chester – a species native to the Indo-Pacific.

And then the patter of tiny fins could be heard in Hastings with the arrival of 200 baby short snouts. These are European seahorses that live around the UK coastline and down into the Mediterranean.

Seahorses have been having babies in British aquariums since Victorian times, so this is nothing especially new. But it obviously still exciting.

As I discuss in Poseidon’s Steed, keeping seahorses in aquariums helps spread the word about these extraordinary creatures and of course raises awareness about the problems they face in the wild. And with breeding programmes like these two, and many others around the world, aquariums don’t have to rely on wild caught seahorses for their displays.

On a more worrying note, if you haven’t already, then take 30 seconds out of your day to watch a video on the Guardian website showing the sea ice at the north pole shrinking from 1978 to 2008.

Back in the late seventies, satellites first started taking pictures from space of the extent of sea ice over the arctic. Since then, the sea ice has fluctuated annually but overall has been contracting, with 2009 being the 3rd lowest extent on record.

And despite the slight recovery from 2008, scientists are still convinced that in the next few years the arctic will become completely ice-free during the summer.

Believe what you will about climate change, but this to me is stark evidence of the changes that have been taking place in the environment in the past few decades, and a worying sign of the changes still to come.

And finally…

This week we saw a cheery bit of ocean trivia. A video of bottlenose dolphins getting up to some strange jellyfish tricks has been doing the rounds.

The footage came from Tremadog Bay in Wales, and you can see the researchers onboard laughing themselves silly at the spectacle.

It’s not too obvious on the video clip but when the dolphins got a good aim, they flipped  the jellyfish clear out of the water.

It’s behaviour that’s never been see before, but perhaps goes some way to explaining why captive dolphins know what to do when a beach ball is thrown at them.

And why are they doing it? Well, who knows. I’d like to think they were just having a bit of fun.

Thanks for reading. More from me and the ocean world soon.
