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.

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.

Northern Madagascar Biotope Aquarium Setup
Ankarana Dry Forest Stream
++++++++++++++++++++++++++++++
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
FISH:
Rainbowfish

Atlantic sturgeon gains protection under the Endangered Species Act
(02/01/2012)
The U.S. federal government has listed the massive and bizarre Atlantic sturgeon (Acipenser oxyrinchus) under the protection of the Endangered Species Act (ESA). Historically overfishing decimated the Atlantic sturgeon, while on-going threats include pollution and infrastructure, like dams and bridges that destroy habitat. Fishing for the Atlantic sturgeon has been banned since 1998, they are still caught as bycatch.
Photos: 46 new species found in little-explored Amazonian nation
(01/25/2012)
South America's tiniest independent nation still hides a number of big surprises: a three week survey to the sourthern rainforests of Suriname found 46 potentially new species and recorded nearly 1,300 species in all. Undertaken by Conservation International's (CI) Rapid Assessment Program (RAP) the survey found new species of freshwater fish, insects, and a new frog dubbed the "cowboy frog" for the spur on its heel. While Suriname may be small, much of its forest, in the Guyana Shield region of the Amazon, remains intact and pristine. The Food and Agriculture Organization (FAO) estimates that 91 percent of Suriname is covered in primary forests, however this data has not been updated in over two decades.
Featured video: tuna industry bycatch includes sea turtles, dolphins, whales
(01/16/2012)
A Greenpeace video, using footage from a whistleblower, shows disturbing images of the tuna industry operating in the unregulated waters of the Pacific Ocean. Using fish aggregation devices (FADs) and purse seine nets, the industry is not only able to catch entire schools of tuna, including juvenile, but also whatever else is in the area of the net.
Bycatch-reducing fish trap wins $20,000
(01/11/2012)
An innovative fish trap that allows small non-target fish to escape won a new content by RARE Conservation and National Geographic to fund solutions to overfishing. Developed through studies in Curaçao and Kenya with the Wildlife Conservation Society, the trap has gaps for juvenile fish to swim out of reportedly reducing bycatch by 80 percent. The entry won a $20,000 grant.
World's most expensive tuna
(01/05/2012)
A 593 pound Pacific bluefin tuna sold for $735,000 (56.49 million yen) in Tokyo's Tsukiji market today. This beats the previous record price hit last year by over $260,000. Why so expensive? Bluefin tuna, considered the best sashimi and sushi in the world, have been fished to near extinction with the population of the Pacific bluefin the most stable to date.
Top 10 Environmental Stories of 2011
(12/22/2011)
Many of 2011's most dramatic stories on environmental issues came from people taking to the streets. With governments and corporations slow to tackle massive environmental problems, people have begun to assert themselves. Victories were seen on four continents: in Bolivia a draconian response to protestors embarrassed the government, causing them to drop plans to build a road through Tipnis, an indigenous Amazonian reserve; in Myanmar, a nation not known for bowing to public demands, large protests pushed the government to cancel a massive Chinese hydroelectric project; in Borneo a three-year struggle to stop the construction of a coal plant on the coast of the Coral Triangle ended in victory for activists; in Britain plans to privatize forests created such a public outcry that the government not only pulled back but also apologized; and in the U.S. civil disobedience and massive marches pressured the Obama Administration to delay a decision on the controversial Keystone XL pipeline, which would bring tar sands from Canada to a global market.
