[98] The largest orders in the Yangtze are Cypriniformes (280 species, including 150 endemics), Siluriformes (40 species, including 20 endemics), Perciformes (50 species, including 4 endemics), Tetraodontiformes (12 species, including 1 endemic) and Osmeriformes (8 species, including 1 endemic). The origin of the Yangtze River has been dated by some geologists to about 45 million years ago in the Eocene,[52] but this dating has been disputed. Based on the successful pilot project, other provincial governments emulated the experience and also reestablished connections to lakes that had previously been cut off from the river. [11] The Chinese sturgeon is the largest fish in the river and among the largest freshwater fish in the world, reaching a length of 5 m (16 ft); the extinct Chinese paddlefish reputedly reached as much as 7 m (23 ft), but its maximum size is labeled with considerable uncertainty.

[110] Dams present another serious problem, as several species in the river perform breeding migrations and most of these are non-jumpers, meaning that normal fish ladders designed for salmon are ineffective.

[94][95], In 2002 a pilot program was initiated to reconnect lakes to the Yangtze with the objective to increase biodiversity and to alleviate flooding. Little formed the Upper Yangtze Steam Navigation Co., Ltd. and built Kuling but his attempts to take the vessel further upriver than Yichang were thwarted by the Chinese authorities who were concerned about the potential loss of transit duties, competition to their native junk trade and physical damage to their crafts caused by steamship wakes. Four years later, a group of researchers traversed 2,000 miles of the Yangtze River to see if … Instead, they spend much of their time at river bottoms, probing with sensitive snouts for mud-loving fish and crustaceans. The problems facing the Yangtze are, in other words, not just isolated to one species, but to the entire ecosystem, and ecosystems that live downstream of the river.
