Thanks for the trust, the answer is as follows:
The red fishing hook I exported
I started fishing in the second grade of elementary school and have been fishing for sixty years. But I know that fish have a preference for color in the 1990s, after the production and export of fishing tackle. One year the Egyptian guest asked me for a red fishing hook, so I quickly looked up the information, figured out why, and then knew:
Fish are not color blind and are sensitive to color.
Different fish have different preferences for color. Freshwater fishing, carp like red, crucian carp like yellow, grass carp like green, this is just one factor to refer to when fishing to lure fish. Whether you can catch fish or not, there are many factors. Especially carp fishing, the key is bait. Or nesting.
Fish forage by sight or smell can not be generalized, Lua fishing method works does not mean that fish feed by vision?
All kinds of soft lua
In fact, the teasing fishing method itself also explains the limitations of fish vision--- objects can stimulate the visual nerves of fish and stimulate the central nervous system of some fish. Why shouldn't we humans? Who wouldn't want to look at a pretty girl, a handsome guy, a naïve little kid?
Fish textbooks say that "fish vision can not only feel the shape of the object, but also feel the color and brightness of the object." ”
The target fish of Lua fishing are mostly ferocious carnivorous fish and predatory fish. The distinction between carnivorous and non-carnivorous fish must be confronted and the difference in feeding habits of pelagic and benthic fish must be noted.
Carnivorous fish have far more developed organs than non-carnivorous fish.
Largemouth bass, eel, mandarin fish, mullet, catfish Yellow jawfish, etc. Although the sense of smell and taste is extremely acute, the visual organs are more developed.

Should fishing focus on the fish's sense of sight or smell? It depends on what fish you want to catch.
Do fish find food by sight or smell? This is a complex issue.
The chapter "Sensory Organs of Fish" in Ichthyology says:
"Fish sensory organs are divided into sight, touch, hearing, smell and taste."
Please note that textbooks talk about fish, not specific types of fish. It means that fish have so many sensory organs, and the specific kind of fish, which kind of sensory it relies on to catch food, also needs to be analyzed in detail.
