Deployment

Thanks for stopping by,
as we say 'ALOHA'
 to a hardy band

Today they get into the canoes.
Over a thousand of them will be taken offshore.

They have been carefully hand-raised
 in a hatchery at Sand Island's Anuenue fisheries research station here on Oahu.

Now they have a job to do:
to restore the natural reef in Kaneohe Bay.

"aggressive seaweed"
 is a growing problem for the fragile reef ecosystem
 in the bay.

(Incidentally, that is the Kaneohe High School Mascot:
"The Aggressive Seaweeds."
Nah! Just kidding!)

“This is the first time we have been able to raise urchins
 in captivity; very few places in the world ever do this,”
 said Christy Martin with the Coordinating Group
 on Alien Species.

Urchins? 



March!


State aquatics resource scientist David Cohen


 and his colleagues collected adult specimens from the wild 


and used their sperm and eggs


 to propagate the microscopic creatures

with a lot of trial and error


 transferring the urchins from tank to tank as they grew.

Cohen calls them his babies,

 and they eat a lot.


“We give them as much variety as we can.


We use native seaweeds and we fatten them up

until they can get out on the reefs and do their jobs,”


 He says.


We needn't  worry about the area being overrun with urchins, though,




“We can actually herd these guys like cows and goats.


We keep them where we want them 
and if they migrate to 
another area,

 we pick them up and move them elsewhere,”
 Cohen said.



The urchin release later today will happen
 in water 2-6 feet deep.


 His "babies' are not very poky, Cohen says.

 "If you happen to step on them,
 you are more likely to hurt the urchin than to get hurt yourself."

Go With God, Little Eco-Warriors!

  1. What a story!
    I wish the only aggression over here was only by aggressive seaweed.
    Cairo is only 425 km, 264 miles away.
    Good luck with your urchins!

  4. Love that urchins are raised to improve the reefs. May the reef be restored to its formal health.
    High surf here, eroding the berms that separate the lake from the ocean.

    Natural changes.

  12. Maybe they should come to the Gulf of Mexico? Do they like oily food? Glad something can help the reef. DrumMajor

  17. Here, I am sitting thinking that somewhere in the world, people are walking in the sunshine, mountains in the backdrop, listening to the ocean. It warms my day, which is gray and expecting freezing rain.
