11. Can fish appreciate ultra-lifelike lures' detail?
The science suggests that fish generally can see such detail, but that this can vary widely. Perhaps the best indicator of that ability is eye size, particularly for fish inhabiting generally clear waters. If you favor very lifelike lures and light fluorocarbon leader, odds are good you're targeting fish with large eyes, such as tunas, equipped to look closely at their prey. They're among many predators with great visual acuity—higher than ours. But exquisitely lifelike detail on lures might be wasted in murky inshore waters. Also, whatever fish do see must be processed and interpreted by the brain. The nuances our eyes take in can be noted and remembered, allowing us to discriminate, for example, the differences in thousands of faces we see over a lifetime. But fish, without our significant CPUs, lack as fine a cognitive ability to interpret what they see. Of course, using very lifelike lures might benefit an angler by giving him confidence, reminding us that lures are designed to catch fishermen.
