This fish is slender and its body coloring is brown. A thick dark brown to black line extends the length of the body, from the end of the snout to the tip of the tail. A thin white to beige colored line is located right above the darker one. The belly is white and the fins are transparent. The eyes are relatively small.

When full-grown, this fish requires a larger tank.   Like most catfish, the Shovelnose Catfish prefers shallow tanks. The tank should have large, open swimming areas.   The tank should be dimly lit, with a cover of floating plants. Use large, sturdy, well-rooted plants.   Small plants will be hopelessly buried or up-rooted.   Provide sturdy hiding places with caves, rocks, or wood. Use fine gravel as a substrate.

Overfishing may hurt Amazon forest trees

Piranhas originated when Amazon was flooded by seawater
(12/4/2007) South America's piranha family of fish -- notorious as eaters of flesh -- can be traced back to a single ancestor which dispersed when the Amazon was flooded by seawater some five million years ago, report researchers from the Institut de Recherche Pour le Developpement (IRD). Today piranhas are exclusively freshwater fish found from the Orinoco River basin in Venezuela to the Parana in Argentina.

How to save the world's oceans from overfishing
(7/8/2007) Global fishing stocks are in trouble. After expanding from 18 millions tons in 1950 to around 94 million tons in 2000, annual world fish catch has leveled off and may even be declining. Scientists estimate that the number of large predatory fish in the oceans has fallen by 90 percent since the 1950s, while about one-quarter of the world's fisheries are overexploited, depleted, or recovering from depletion. Despite these dire trends, the situation is changing. Today some of the world's largest environmental groups are focused on addressing the health of marine life and oceans, while sustainable fisheries management is at the top of the agenda for intergovenmental bodies. At the forefront of these efforts is Mike Sutton, director of the Monterey Bay Aquarium's conservation program: the Center for the Future of the Oceans. The aquarium, which has long been recognized as one of the world's most important marine research facilities, is pioneering new strategies for protecting the planet's oceans. Sutton says the approach has four parts: establishing new marine protected areas, pushing for ocean policy reform, promoting sustainable seafood, and protecting wildlife and marine ecosystems.
