Artificial though they may be—often lacking natural vegetation or wood cover—these small urban waters collect profusions of fish around manmade spillways, bridges, culverts or the odd submerged shopping cart; any object creating current and oxygen or cascading a blanket of shade. To intercept larger, especially cautious fish, accomplished urban anglers prefer to hit the water at dawn, dusk or well after dark. They do their reconnaissance online (spot-scouting on Google Earth) and aren’t afraid to hike in a few miles to check a juicy little sweet spot away from the crowd. And because these waters are mostly shallow, sight fishing and staying alert for “signs” pays rewards. “Instincts are everything with this style of stealth fishing,” suggests Pat Kohler, a frequent canal sneak who pursues an eclectic collection of gamefish in the southern tier of Florida. Like most of his buddies, Kohler has developed a keen interest in conquering some of Florida’s newest fresh- and brackish-water arrivals. “Over the last couple decades, these canals have been illegally planted with a bunch of different exotic species, most of them ex-aquarium inhabitants native to South America and Southeast Asia,” notes Kohler. The extraordinary clown knifefish, for example, is a native of Thailand and Vietnam. Kohler says numbers and size of knifefish in various Florida canals has slowly expanded. To date, he’s caught specimens up to 10-pounds, with larger fish up to 15 possible. He explains that while largemouth bass previously dominated these flood-control canals, exotics such as peacock bass appear to displace native largemouth populations. “These days, if I catch five largemouths, that’s an epic outing. Peacocks are just crazy predators. While largemouths lurk and ambush their prey, peacocks can both ambush and actively hunt away from cover. |
