Northern Madagascar Biotope Aquarium Setup
BIOTOPE AQUARIA

A biotope aquaria is an aquarium that is set-up to simulate a natural habitat. The fish, plants, water chemistry, and furnishings are similar to those that can be found in a specific natural setting.

Limestone Tsingy in Ankarana
Flooded Forest, Madagascar

Malagasy Crayfish According to Bradt 2001, six species of crayfish have been described in Madagascar, all of which are endemic. What makes this occurrence particularly interesting is crayfish are not present in Africa or India -- meaning Malagasy crayfish may have much older origins. Today crayfish are a vital source of protein to many in Madagascar.

Madagascar's fish species are some of the most threatened on the planet. Habitat loss -- especially the conversion of native vegetation to rice paddies -- combined with horrendous erosion resulting from deforestation and the introduction of exotic species (especially Tilapia, Snakeheads, Mosquito fish) have devastated endemic species. Several of Madagascar's unique species are no longer recorded in the wild. The plight of Madagascar's fish species mirrors the degradation of its terrestrial habitats.

One of the most beautiful aquatic habitats I have ever seen was in Ankarana -- a stretch of dry forest in Northern Madagascar. The creek was shaded by a high canopy but richly endowed with gorgeous aquatic plants (shafts of sunglight penetrated the canopy). The substrate was fine sand and the banks of the stream were packed earth. At the time I didn't pay too much attention to the fish or aquatic vegetation as I was focused on the remarkable crowned lemurs and fascinating reptiles found nearby.

Sadly I do not have any pictures of this magnificent habitat -- it was among the rolls of film that got destroyed over the course of a very rough trip.

    WATER:
    pH: 7.0-8.0, 8-19 dH, 75-84 F (24-29 C)

    TANK:
    Use silica (silver) or very fine gravel for the substrate. Lighting can be bright and the tank should be heavily planted. Driftwood can be used as desired. The water should be clear and have a slow to moderate current.

    PLANTS:
    The following plants are among those found in Madagascar: Aponogeton boivinianus, Aponogeton longiplumulosus, Aponogeton Madagascariensis [the plant has been so sought after that is have been depleted over its natural range (care tips, more info)], Aponogeton ulvaceus, Lagarosiphon Madagascariensis, Bacopa Madagascariensis, Hydrotriche hottoniifloria, Blyxa aubertii, and Cyperus alternifolius

    New Yangtze River dam could doom more endangered species

    (06/22/2009) Eight Chinese environmentalists and scientists have composed a letter warning that a new dam under consideration for the Yangtze River could lead to the extinction of several endangered species. The letter contends that Xiaonanhia Dam, which would be 30 kilometers upstream from the city of Chongqing, will negatively impact the river’s only fish reserve. Spanning 400 kilometers in the upper Yangtze, the reserve is home to 180 fish species, including the Endangered Chinese sturgeon, and the Critically Endangered Chinese paddlefish, as well as the finless porpoise.


    Fish take less than a decade to evolve

    (06/22/2009) Evolution is often thought of being a slow-process, taking thousands, if not millions, of years. However a new study in The American Naturalist found that Trinidadian guppies underwent evolution in just eight years, or thirty generations. Less than a decade ago Swanne Gordon, a graduate student at UC Riverside, and her team introduced Trinidadian guppies into the Damier River in the Caribbean island of Trinidad. They placed the guppies above a waterfall to allow them to flourish in a largely predator-free environment.


    Madfish?: scientist warns that farmed fish could be a source of mad cow disease

    (06/17/2009) In a paper that shows just how strange our modern world has become, Robert P. Friedland, neurologist from the University of Louisville, warns that farmed fish could be at risk of Creutzfeldt Jakob disease, or mad cow disease.


    New report predicts dire consequences for every U.S. region from global warming

    (06/17/2009) Government officials and scientists released a 196 page report detailing the impact of global warming on the U.S. yesterday. The study, commissioned in 2007 during the Bush Administration, found that every region of the U.S. faces large-scale consequences due to climate change, including higher temperatures, increased droughts, heavier rainfall, more severe weather, water shortages, rising sea levels, ecosystem stresses, loss of biodiversity, and economic impacts.


    Will jellyfish take over the world?

    (06/16/2009) It could be a plot of a (bad) science-fiction film: a man-made disaster creates spawns of millions upon millions of jellyfish which rapidly take over the ocean. Humans, starving for mahi-mahi and Chilean seabass, turn to jellyfish, which becomes the new tuna (after the tuna fishery has collapsed, of course). Fish sticks become jelly-sticks, and fish-and-chips becomes jelly-and-chips. The sci-fi film could end with the ominous image of a jellyfish evolving terrestrial limbs and pulling itself onto land—readying itself for a new conquest.


    Marine scientist calls for abstaining from seafood to save oceans

    (06/08/2009) In April marine scientist Jennifer Jacquet made the case on her blog Guilty Planet that people should abstain from eating seafood to help save life in the ocean. With fish populations collapsing worldwide and scientists sounding warnings that ocean ecosystems—as edible resources—have only decades left, it is perhaps surprising that Jacquet’s call to abstain from consuming seafood is a lone voice in the wilderness, but thus far few have called for seafood lovers to abstain.
