Science as Leisure

Liz Marchio

I am a trained ichthyologist interested in what gets people interested in natural history, biological sciences, and science careers. My passion is to find out what fuels curiosity for the natural world.

Biology-related serious leisure activities can impact people's interest in ecology, biology, and natural history. Do these activities promote biological understanding? If so, how does that progress and to what level does it progress to? 

If you're interested in a starting a dialogue, please feel free to contact me. If you're curious about how I got here, my story can be found on the About Me page.

Attention Percula Clownfish Breeders!

I'm in need of:


Data collected from clownfish breeders will be used to create an economic model for this purpose:


Private breeders, responding to market forces, are responsible for a surprising amount of conservation of endangered exotic species occurring within the United States. Tropical birds, African ungulates, and marine fish are being raised to provide animals for pets and wild game hunting.  These private actions can play a critical role in biodiversity protection, supplementing conservation in native habitats and zoos. Breeders who are active in these markets, however, have often complained that the Endangered Species Act (ESA) can create obstacles that make breeding uneconomic, actually increasing the likelihood of extinction. In this paper we consider the conditions in which ESA and ESA-like regulations can have perverse impacts, harming prospects for ex-situ conservation without meaningfully impacting wild animal populations.

Motivation and Three Cases:

The paper is motivated by three cases (hyacinth macaw, antelope, clownfish)  in which breeders play a role in protecting endangered species, but the economic viability of those enterprises is threatened by proposed or existing policy.

I need data to run this model! 

If you are willing to share information on your percula clownfish breeding operation, please fill out this survey with as much information as you can. It is understandable that some people may not want to share their secrets to success, but hopefully these are fairly benign questions.

The information you provide will be used to create an economic model that, in turn, will start a few publications on the complex nature of the ESA and captive populations of fish bred by aquarists.

Again, the survey can be found by clicking this link: SURVEY

Thank you for your consideration!


Killing Animals for Decoration

Ever look at a hunter's wall and think how unnecessary that wall of death is?

That's a lot of dead animals...

That's a lot of dead animals...

Well, as gross as that may be to some people, I have an even bigger beef to talk about- people who keep dead animals in their homes and don't even know it! 

I'm talking about the Curio trade. You know, dead starfish, coral, and fish like pufferfish and seahorses! 

Googly eyes are like my favorite thing on earth, but it seems a bit disrespectful on a dead animal decoration!! 

Googly eyes are like my favorite thing on earth, but it seems a bit disrespectful on a dead animal decoration!! 

I googled "dead puffer" images and no curio puffers showed up on the first visible page. This lends support to the idea that people do not understand a dried puffer is actually a DEAD puffer. 

This is a trade that permits collectors to collect namely marine animals for decorations. It's not illegal, but it is almost completely unnecessary and definitely tricks people! I don't know how many people I've talked to or seen online that are confused when they learn a dried starfish from the $1 store at Mission Beach is actually a REAL DEAD animal! Some even try to put these DEAD ANIMALS into their AQUARIUMS!

No, you cannot stick a dead animal into your aquarium!

Not only are consumers unaware of the dead nature of these "decorations" they are fully unaware of the process of  making them dead. People who collect these animals are collecting LIVE specimens, and many times allowing them to suffocate slowly in order to keep their shape and color. How do you think a dried seahorse is in that cute seahorse shape? It's dying and molded into an attractive pose.

Avenge me, brother!

Avenge me, brother!

Other times animals, especially those with shells, are simply bleached alive. I remember I was looking for shells on one of the beaches in South Carolina and saw a man with a HUGE beautiful shell. It was a conch-type animal and it was very much still alive. He was a stranger but still openly stated, "I'm going to keep it for it's shell". RIP you poor, and probably decade-old, thing. 



So, is the killing of sea animals, especially in the face of extinction and loss, really necessary? Do you need some sea shells sitting in some sand on the toilet? Do you really need to buy your kid that googly-eyed pufferfish that they will forget about in a week?

Probably not. 

So what do you do? Well, (1) spread the word that these animals actively die for the curio trade. They aren't washing up on beaches, they are collected and systematically killed for decoration; and (2) stop buying these things. As I said in my Walmart fish post, if you don't want to promote the consumption of something, stop buying it yourself.

What could be any easier than NOT buying something?

Disclaimer: if you are purchasing shells that were collected for meat and done so appropriately, fine. And yes, there are cultures that eat and use seahorses as food or medicine. Maybe those things are fine, maybe not, but what we can do here in the States is at least stop the consumption and thus the collection of live animals only to be killed for decor. Please pass this information along!
