Chemoreception in fish, i.e. gustation and olfaction or more simply taste and smell, can play a large role in fishing success. While all fish can likely taste to some degree, taste would not be considered to be a primary means of identifying food for most fish. The one great exception…
When I started researching about hearing in fish I really started to get bogged down in a lot of biology and physics, things like bone conduction, transmission of sound in water and inverse square laws come to mind. After a bit of this I realized that for our purposes as…
As an addendum to the previous post, I’ve gone through a number or sources for the various depths at which the various colors will no longer be discernible underwater. For most freshwater rivers and lakes color loss underwater will be at approximately: Red ~15-18 ft (5 m) (note: after 5…
The various senses that fish use to navigate their watery world are of utmost interest to us as anglers. For each species a particular set of senses will dominate their hunt for food and our knowledge of this can be used to fool them to take our bait. As with…
In a previous post we looked at the temperature classification of different fish species – cold water, cool water and warm water. For each fish species there is a preferred temperature range that, given the choice, they will spend more time in. This “thermal optimum” temperature will not be too…
The effect of water temperature on fish is of incredible importance. Different fish can tolerate different water temperature ranges and, as cold blooded species, can suffer or die if they are subject to temperature outside of their range. They will also need a specific range of temperatures for successful spawning…
