    Default Crustahunter Tour 2008 with Chris Lukhaup

    Hi everybody,

    these blog entries and pictures are made available to us courtesy of Wirbellosen-Auktionshaus.de. My special thanks go to Andreas (Garnelenfan)!
    The original text in German can be found here:
    Wirbellosen-Auktionshaus visited the Georgia Aquarium in Atlanta in the course of the USA Craytour 2008

    On the first day in the US we went directly to the Georgia Aquarium in Atlanta:



    Here are some photos:

    Big cinema in Atlanta- USA
    Over 100,000 fish in 24 million liters of water on an area of 500,000 square meters in the middle of Atlanta's city center - that is the Georgia Aquarium, which makes it the world-wide no. 1 among show aquariums. A billionaire with a preference for large fish and huge buildings conjured this gigantic aquarium out of nothing and has pumped over 200 million $ into this project. Bernard Marcus, called "Bernie" by everybody, 77 years old, founded "Home Depot" in the seventies, which is now the leading hardware store chain in the world.
    The aquarium consists of five sections that come together in the middle of the building, thus forming a star.
    The "River Scout Gallery“ emulates river or lake systems as we can find them in Africa, South America, Asia and also in Georgia. River Scout is the only section in the Georgia Aquarium housing freshwater animals. 98% of the aquarium consist of sea water, though. Sturgeons swim above the visitors' heads in an impressively lighted tank and give the visitors an uncommon perspective. Together with Amazonas fish the largest freshwater fish of the world can be seen: the predator Arapaima.
    At the entrance, visitors are greeted by a colorful Malawi tank, and a little further large groups of Piranhas can be watched circling around their tank. A pop-up window lets the kids see the razor-sharp teeth of the Piranhas.
    In the Asia section the smallest otter species can be overserved searching for food or playing.
    The section "Georgia Explorer" is also called Discover Our Coast and is especially interesting for kids, who find a huge playground area. One of the highlights for kids is, of course, the simulated shrimp boat. There visitors are to get to know native American coastal animals like horseshoe crabs, starfish, shrimps and rays. This area is a kind of petting zoo, and children as well as grown-ups gather round the five pools in order to be able to touch these bizarre creatures.
    The "Ocean Voyager", sounding like a US afternoon series, is not as exhausting: The tour starts through an over 30 meter long tunnel, allowing to see 6.33 million gallons of sea water and its inhabitants from below and enveloping the visitors from three sides. The visitors to this section are transported on a moving walkway as if they were at the airport. They just have to direct their view to the ceiling and gaze in wonderment. -. In a large, dark hall of the "Ocean Voyager" there is the true highlight of the aquarium - the fish cinema. Here, entire school classes marvel at the deep insight they get through the huge glass wall, behind which thousands of colorful fish can be seen swimming. No other aquarium houses as many fish species as the Georgia Aquarium. And there they are, the world's largest fish. The whale sharks, belonging to the monotypical genus of Rhincodon, are the largest of all recent sharks and, at the same time, the largest living fish known today. This species is assumed to grow to 18 to 20 meters in length, however, the longest whale sharks measured up to now never exceeded 14 meters at a weight of over 12 tons. This makes the Georgia Aquarium the only aquarium in the US and in the entire world that is able to house these four giants. Only in Asia two further exemplars of this species can be seen. This aquarium's staff are able to interpret practically every inhabitant's movementes. Here, the focus lies on the education mandate the aquarium has given itself.
    Life moves a lot more slowly in the "Tropical Diver" section, which is dark, mysterious, and resembles an art gallery more than an aquarium. This section is also called "The Living Gallery", not a coincidence. Purple jellyfish look like ink spots on a deep blue background. This section was designed to give visitors a little break. Deeper inside this section the amazed visitor can see a reef populated by beautiful corals, living and artificial ones.
    Cold Water Quest – The Chilly Unknown; this is the section presenting animals from the polar regions to the temperate zones. Here you can find another attraction of the aquarium - the charismatic beluga whales. They glide through the cold waters, seemingly weightless. Before this window you can forget about the outside world. There are only cold blue immensities and the belugas, smiling back at you when you wave at them - as it seems.
    Penguins, sea lions and a giant octopus from the vastness of the Pacific can be seen here.
    This section allows an overview over the highly interesting and manifold cold sea fauna. The Georgia Aquarium can afford the luxurious ambience for its animals: Other than the further 36 American aquariums, the Atlantans do not have to worry about covering the costs, as this aquarium is the hobby of a billionaire. However, Bernie does not just have a hobby, he also has a vision. His aquarium is to re-vitalize downtown Atlanta and to bring about a comeback so many American inner cities, left by their residents, crave. Reader’s Digest declared this aquarium to be among "America’s 100 Best". In the first year, 2.4 million visitors were anticipated, however, in reality, nearly 4 million people had visited the aquarium by the end of 2006. An average of 100,000 visitors a day come to the aquarium. Economists claim that the aquarium's share in Atlanta's economy will exceed 5 billion dollars within the first five years.

    Three cray species for starters

    On Sunday, September 7, 2008 the USA Craytour really started:
    Together with the biologist Chris Skelton (Georgia College), we didn't only catch numerous Cambarus englishi in the rather small Tallapoosa* River in the US state of Georgia, but also Procambarus acutus and several Cambarus halli.
    * Indian name



    Some photos:

    Then, a new location: Our new destination was Little Cedar Creek:
    The hearts of all crayfish friends present were beating faster when the first Cambarus manningi were caught in our nets.

    Hot time in Florida, rainy night in Georgia

    Warm and dry in Georgia: On Monday, September 8, 2008 we went on to Summerville, Georgia. There the participants of USA Craytour 2008 found Procambarus acutus and Orconectes spinosusim in the small creek Town Branch. After that Chris Lukhaup gave us some great hints on the subject of underwater photography, and after that a little Photoshop workshop for the members.
    Somewhere on a highway in Georgia on the way to Alabama we saw another small river. In these beautiful waters named Flint River the Crustahunters found numerous crayfish, too.
    Under large stones on the banks we even found three of the manifold snake species native to Alabama.

    Georgia on my mind - but now we're going on to Alabama

    On Tuesday, September 9, two rivers in the State of Alabama were the destination of the Crustahunters: Orconectes cooperi and Orconectes validus were caught in the waters of the Indian Creek and Brier Fork.
    Besides inverts we were also able to photograph cotton plantations, hummingbirds and insects like mantis.

    Several crayfish species caught in the State of Missouri

    On Wednesday, September 11, 2008 the USA Craytour went on to some affluents of the Black River in the State of Missouri. The Crustahunter team was able to catch the following crays, et.al.: Orconectes punctimanus (the red-lined pleon is green on all its segments as well as on the telson), the widespread Orconectes hylas as well as the rare Cambarus hubbsi.

    Golden crays in Missouri

    New day, new luck: After a nightly cray-catching excursion with headlamps on the day before, the Crustahunter team naturally was also on the prowl for crayfish on Friday, September 12, 2008.
    Besides several "old acquaintances", the crew found several Orconectes luteus this time in Maramec River. This crayfish is called golden crayfish in North America.
    Truly special: The Maramec River golden crays' joints are lined red.
    Clear, clean water in Maramec River: These are also the living conditions of the species Orconectes medios native in this river.

    There were also intersting aquatic snails in this biotope.

    Cave Crayfish - blind crays in the Mammoth Cave in Kentucky

    Under the sand stone of the hills of Mammoth Cave National Park there is the longest cave system of the world. The labyrinth was formed by water, and after 4,000 years of (although interrupted) exploration its total length is still in the dark. With over 560 kilometers of reconnoitered cave passages, Mammoth Cave in Kentucky is at least three times longer than any other known cave in the world.
    The huge cave system is habitat to a subterranean ecosystem being the richest in species diversity world-wide. The Crustahunters were able to take photos of several blind cave crayfish and blind cave fish in the cold water. The albinotic crayfish of the species Orconectes pellucidus reach an age of about 100 years. In the caves, the Crustahunters also found bats and crickets.

    More information: http://www.nps.gov/maca/

    Found: North America's largest cray species

    Barbicambarus cornutus is (not considering the claws) the largest crayfish of North America. It can grow to a length of up to 20 cm. The Crustahunters found this medium-sized specimen in an affluent of Green River in the State of Kentucky on Sunday, September 14, 2008.

    Guns and mosses

    Cambarus graysony: The Crustahunters found this brown, larvae-carrying female in an affluent of Green River in Russelville in the State of Kentucky on Monday, September 15, 2008. The largest cray of this species caught up to now was a female with a carapace length of 6.8 centimeters.


    Cambarus graysony


    Not only guns and country music in Kentucky: Besides Cambarus graysony we also found an interesting, delicate aquatic moss in Mud Creek. The water temperature was at about 18 to 20 °C.

    One of North America's most beautiful crays

    There are several variants of Cambarus rusticiformis, differing in coloration and patterns. The probably nicest variant has blue legs and a beautiful pattern on its carapace and pleon.
    The Crustahunters were able to observe several of these exemplars in southern Kentucky and northern Tennessee on Tuesday, September 16, 2008.
