Abstract
"Paddlefish, sometimes known as spoonbill, are among the oldest fishes in existence; fossil records date their appearance to before the first dinosaurs. The North American paddlefish (Polyodon spathula) is distinguished by its long, paddle-like snout, or rostrum (Figure 1 ). Its nearest living relative, the Chinese paddlefish (Psephurus gladius), is found in the Yangtze River and has a cone-shaped snout. Paddlefish commonly inhabited and moved freely within large, free-flowing rivers, channels, backwaters and oxbow lakes of the entire Mississippi River drainage. However, significant declines in paddlefish stocks have been occurring throughout their range. One of the primary reasons for the decline in paddlefish populations is the loss of spawning habitat due to the alteration of river habitats. Reservoir construction has eliminated many traditional spawning sites and interrupted natural spawning migrations. Pollution, illegal fishing and overexploitation by commercial anglers has also contributed to the decline." -- first page
