The criteria for selection are as follows: (1) Good steel quality, sharp hook point.
The standard fish hook should not be bald, not hollow, and should be sharp and round. When selecting, it should feel sticky when gently touching with your hand.
（2）钓条坚韧有弹性；

Good fishing rods should be able to withstand the struggle of the fish and the pull of the rod, and their hardness and toughness should be good. To do this, you can pull the fishing tip with your hand to test its elasticity and hardness.
（3）thorns are distinct;
The purpose of the barb is to ensure that once a fish has swallowed the hook, it cannot spit it out. It is made by slantingly cracking the hook's lower part. The manufacturing process is very precise, as the cracking must be just right. If the cracking is too deep, the angle of the barb becomes too large or too high, which is ineffective. If the cracking is too small, the barb is not noticeable, and it does not work. Therefore, the cracking must be just right. Some fishing hooks also have a back barb, which is best at a 30-degree angle.
(4) The blanks should be as thin as possible to facilitate hooking;
Under the same tension, the finer the fishing hook, the easier it is to pierce the fish's mouth, so the rate of catching fish with fine hooks is higher. Fine hooks require better electroplating layers to ensure their durability. Most commercially available fishing hooks are electroplated with yellow, black, or white layers, with white being the best.
The bend of the hook is appropriate.
Hook ears are of equal size, making it convenient to tie fishing lines.
A fishing hook can be divided into six parts based on its structure: the hook shank, hook handle, hook back (bottom), hook tip, hook point, and hook barb. The hook shank's role is to prevent the line from slipping out. There are various shapes such as straight flat, side flat, ringed, and barbed heads. As long as it is suitable, there is generally no need to pay attention to it. The hook handle can be long or short. Long-handled hooks are suitable for using long shapes such as worms and insects, while short-handled hooks are suitable for using small granular baits such as gluten and rice grains. The hook back has shapes such as round, flat, inclined, and arched. From a mechanical standpoint, a round back hook can withstand greater tension, while a flat or inclined back hook can withstand less. If the steel is used, it should be chosen according to the fishing situation.

The hook is designed to be easily detached once it is hooked onto the fish. The width of the hook shank varies. The distance between the handle and the point is the width of the hook shank. If it is too narrow, the hook may not fully penetrate the fish's mouth and the fish may be able to break free; if it is too wide, the hook may not be able to withstand as much tension. The ideal width should be based on the size of the entire hook, so that the hook point, hook shank, and handle essentially form a circular shape.
The hook is large, the circle is also large, and the width increases. After the fish is hooked, the hook back plays a main role in bearing force, and the different shapes of the hook mainly lie in the hook back, which is the most worth noting. The length of the hook end means the depth of the meat after entering the hook. It is long, the depth of the meat is deep, but it is not easy to enter the hook; it is short, it is easy to enter the hook and easy to be removed. The hook tip requires sharpness, but if it is too sharp, it is easily caught by water plants and so on, and it is difficult to string earthworms. The barb requires clarity, if it is too long, it is troublesome to remove the hook, and if it is too short, it will lose the role of the barb.
Novice fishermen generally leave it to chance when it comes to choosing fishing hooks, many simply assuming that any hook will do. In fact, experienced anglers are very particular about the selection and use of their hooks. According to the experience of fishermen, most of the avid anglers in our country choose different types of hooks depending on the fish they are targeting.
In fish ponds and channels, fishing for small fish such as carp, bream, etc., should use small-sized sleeve and circular mouth hooks, with sizes ranging from 4-7 to 3-5 for Ishigaki and 0.8-1 for Kainomaru. For competitive fishing, choose Kanto 5-8 and Ishigaki 5-8. When selecting fishing hooks, you can use the hook point to "

Gently drag the hook over the nail of the thumb, selecting those that are difficult to drag on the nail, as if they are sticky and rough, and can leave a white imprint when slightly forcefully dragged. The hook bar should be as thin as possible in the same type of hook, with good toughness and elasticity. As for the color of the hook, it can be chosen according to personal preference, such as black, green, blue, metallic white, and red.
To fish for large fish such as carp, grass, green, silver, and so on in rivers, fish ponds, and reservoirs, you should choose large hooks such as the 2,000-yen 2nd, Eshiki 9th, Maruishi 12th, and domestic black carp 8th, as well as the 921th or above of Changhai. The hooks should have distinct barbs, and the distance from the hook tip to the barb should not be too long. If the fishing target is carnivorous aggressive fish such as tilapia, white carp, and red fins, you should choose larger long-handled hooks, such as the 312-315th of Changhai, the 13-19th of Maruishi, the 9-12th of Xishui, or the 12-14th of Eshiki, as well as the 3rd or above of 2,000-yen.
In fish ponds, lakes, and reservoirs, using bomb hooks and combination hooks, and loop hooks, it is generally recommended to use the Ishigaki type hook. Black ones are more commonly used, and you can choose the Ishigaki 7-12, or the stream 5-8 if needed. Of course, smaller fishing hooks can have a higher catch rate if used properly. For fishing in seawater, long-handled large hooks are usually used. Because most sea fish are carnivorous, they often swallow the bait and hook together when feeding aggressively. This can be quite inconvenient for fishing. Therefore, it is recommended to use long-handled crane beak-shaped hooks, such as the long sea 312-315, or the Maruyuki 12-17, etc.
When tying hooks, pay attention to the following: no matter what kind of fishing line you use, you should tie the two loops at the top and bottom of the line to the inside of the hook to ensure that the direction of the pulling force is correct when fishing, so that the fish does not slip off the hook. If you use a multi-strand silk line as a leader or tie your own bomb hook, do not wrap more than four times when tying the hook, as too many wraps will make it harder to tie tightly, and the silk line is more likely to come off the hook shank. You can also use an "8" double knot line, which can make the hook tied more tightly and firmly.
Maintenance of Fishing Hooks

After each fishing trip, it is necessary to clean the hook and the barb channel of the hook to remove any debris, and to dry it promptly. Do not store the hooks in oil or powder. These substances will leave an odor on the hook. Fish have very sensitive senses of smell, and hooks with these odors can have a negative impact on their feeding behavior. Maintenance of fishing hooks: After using the hook, it should be wiped clean, and it should be allowed to dry before being wound onto the spool or cylinder. To prevent the spare hooks from rusting, they can be stored in a powder box or bottle, or they can be coated with oils such as Vaseline, wrapped in tin foil, and then stored in a plastic bag.
Many friends who enjoy fishing with sea rods do not pay attention to the maintenance of the hooks during use. After returning home, they are too lazy to move the fishing gear, and over time, the hooks rust and become dull. When fishing, they often see the rod moving but do not see the fish caught, leaving a regret. If you pay attention to the maintenance of the hooks and keep them clean and shiny, then you will inevitably reduce many "regrets". In addition to the size of the hook, the most important thing is to ensure its sharpness. Because when fish feed, they suck the bait and hook into their mouth at the same time. When they find an object, the sharp hook tip has already adhered to the inner skin of the mouth, and they cannot spit it out. As soon as they struggle, they will deeply pierce. This is different from the hand rod, which is actively piercing, while the sea rod is passively piercing. Clearly, whether the hook is sharp or not is the key factor to improve the rate of catching fish. As a lover of sea rods, you must always remember this.
Fishing with a sea rod is all about two things: bait and hooks. The former ensures the bite rate, and the latter ensures the catch rate, and both are complementary and indispensable. The main maintenance of the fishing rod is to adopt the following simple methods, the key is to be careful and diligent.
1. After each fishing trip, no matter how tired you are, do not forget to lay out all the fish hooks used that day in a well-ventilated place to dry and air-dry.
2. Regularly check each fishing hook individually, and if any have rust spots or become dull, use a small piece of fine sandpaper to polish them a few times to restore their shine and sharpness. If a hook is truly unusable, discard it without hesitation; there's no need to hold on to it.
3. Whether it is a bomb hook, a string hook, or a box hook (box lunch), it should be wrapped in paper after the above processing, not in plastic paper or plastic bags, to avoid moisture. The former is breathable, while the latter is not.
The water quality is not very good now, and fishing hooks are easily corroded, so it is particularly important to maintain the fishing hooks scientifically. This applies to both foreign fishing hooks and domestic ones. In fact, maintaining fishing hooks and playing with fishing gear is also a kind of fun.
The quality of the fishing hook

Choosing a fishing hook involves more than just studying the hook shape; one must also pay attention to the quality of the steel. Hooks that are too brittle or too soft are not ideal. A good hook should be strong, tough, and sharp. Strong means it is durable. If the hook is too thin, it is prone to deformation when used, and if a large fish is caught, the hook can be pulled straight, leading to a lost catch. The thickness of the hook can be judged by visual inspection and touch. The sharpness of the hook is also important. When a fish takes the bait, the angler can simply move the rod lightly, and the hook can catch the fish's mouth. There is a simple test method to determine if the hook is sharp: place a piece of cotton cloth flat on a table, put a fishing hook randomly on the cloth, and then lift one side of the cloth with both hands. A sharp hook can be lifted by the cloth. In addition, anglers might want to perform some destructive tests on the hooks they buy: hold the hook handle with a pair of pliers, and if the hook point can pierce a piece of wood when pulled, then the steel is too brittle and should not be used. If the hook straightens when pulled, the steel is too soft, and it is also not suitable. If you catch a large fish or a stone, and find that the hook is deformed, it should be discarded and not used. Do not let a small problem lead to a big loss, and regret it later.
Types and Their Usage Methods

Uppercut Hook

Commonly known as the standing hook, also known as the weight hook. Its characteristic is that the hook and weight are integrated. The lead weight is located on the hook eye of the fishing hook, with an oval shape and a groove in the middle, used for tying the fishing line. Some are also made by welding lead with copper skin. When the fishing hook is submerged in the water, the buoyancy of the fish float makes the hook point upward, higher than the underwater plane, less likely to be covered by mud or water plants, which is beneficial to the fish biting the hook, with a relatively high hook rate, and both large and small fish can be caught. It is very popular in the Yangtze River basin in China.
When it comes to the Chongtian Hook, it's impossible not to talk about traditional fishing. Long pole and short line fishing. The configuration of the Chongtian Hook is usually a main line directly tied to the hook groove with a bottom color, and the fish float is mainly made of seven star floats and standing floats. Due to the integration of hook and weight, when a fish bites the hook, the fish signal is often a floating signal, and only when larger fish such as grass carp, green carp, and bream bite the hook, will the fish float show as a black float. The use of the Chongtian Hook is very wide, it is the main fishing equipment for wild fishing. A hand pole with a set of traditional fishing equipment can be used to fish in complex natural environments. In addition, there is more flexible mobility. The advantage of fishing in grass ponds. These are all superior to the suspended sinking fishing. In addition, the Chongtian Hook is almost all with barbs, after a fish is hooked, due to the effect of the barbs, it is difficult for the fish to be released, which is deeply welcomed by senior fishermen and beginners.

Eye Hook

Also known as reclining fishing, this method uses a hook without a weight, with the line directly attached to the hook eye. About 3-5 centimeters from the hook, a small lead sinker the size of a green bean is clipped. When casting the rod, the hand swings forward to throw the hook into the fishing spot. The fish bite signal is: the float is lifted (sent floating), or it is black floating, and there is also dragging floating. This fishing method is suitable for older people with slower reactions, especially for leisure fishing enthusiasts.

eel hook

Take a bicycle spoke, one end sharpened into a hook shape, and tie a 20-centimeter piece of bamboo to the other end. Use a thick earthworm as bait, attach it to the hook, and slowly probe into the eel hole. When you feel a fish biting the hook, quickly turn your hand 90 degrees and bend it, so that the hook pierces the lower jaw of the eel. Then, suddenly pull outward to catch the eel.

triangular anchor

The three-claw hook is pointed upward, divided into equal parts at 120 degrees from the anchor handle, and the handle tail has a ring for tying a line. It is commonly seen in the dipping powder fishing in the Guangdong and Guangxi regions and Fujian in China. The principle of this fishing method is similar to the two-foot anchor hook, both of which are used to hook the fish with difficulty. In addition, this anchor hook can also be made into a copper badge fishing group, used to catch aggressive fish such as fish whitefish, fish zongyu, and fish ganyu. When fishing, choose the rapid current and the waters with strong winds and waves to cast the hook, using the fishing line reel to receive the line and the shiny copper badge to attract the fish whitefish or fish ganyu to feed. When the fish bites the hook, the angler will feel a noticeable tension on the rod, and a strong pull of the rod can catch the fish.

"细条钩与粗条钩"可以翻译为 "Fine Hook and Coarse Hook"。

There are not only differences in size and shape, but also differences in thickness in fishing hooks. The thickness of the hook bar is related to the hook size. In normal circumstances, the hook size of the fishing hook is proportional to the thickness of the hook bar, that is, the larger the hook size, the thicker the hook bar, and the higher the tensile strength of the fishing hook. On the contrary, the smaller the hook size, the thinner the hook bar, and the weaker its tensile strength. However, not all small hook sizes have thin hook bars and poor tensile strength. We know that the main factor affecting the tensile strength is the material of the hook bar. The better the quality of the steel wire, the stronger the tensile strength, and in addition, the rationality and science of the hook bar angle can also enhance the tensile strength of the fishing hook. Taking the example of the Eshi Ni hook, the thickness of the hook tip is different, which makes the role of the thick bar hook and the thin bar hook different. The thick bar hook is often used to catch larger fish. For example, in freshwater, such as green carp, grass carp, carp, silver and large head, or in marine waters, such as black sea bream, true sea bream, etc., these kinds of fish often eat more vigorously and have strong power. If you use a thin bar hook to fish, it is very easy to cause the hook to be straightened, broken, and the fish escapes. The carp, which is cautious in feeding, has small body shape and struggles, and small mouth shape, can use thin bar small hooks to fish them. The advantage of the thin bar hook is good concealment, thin hook bar, strong penetrating ability, small target, and can be used to catch the clever fish in the pond, with good effect. The advantage of the thick bar hook is high tensile strength, which is not easy to be pulled off after catching the fish, but the disadvantage is that the penetrating ability is poor, which may cause the fish to be cautious, affecting the bite rate of the fish, and is not suitable for catching smaller fish.

Long-handle hook and short-handle hook

Long-handle hooks are often used in deeper water bodies, suitable for fishing depths over 2 meters. Due to their long handle, even if the fish is struggling for a long time after being hooked, it is less likely to break free. Long-handle hooks are typically used by anglers who prefer to use casting rods to attach multiple hooks. The representative hook types of long-handle hooks include Marubashi, Gohyu, and Crane Beak.
Short-handle hooks represent hook types such as marubushi, Isumi, marusode, and kame-gata, and are mainly used for fishing in shallow water areas with a depth of less than 2 meters. Due to the higher bite rate of short-handle hooks compared to long-handle hooks, they are widely used, and many anglers re-process them by welding a hook with a line slot (turning hook) at the eye of the hook, which is used for fishing freshwater fish. The difference between long-handle hooks and short-handle hooks is that the former is mainly used for fishing deep-water fish such as carp, green carp, and grass carp, while the latter is mainly used for fishing shallow-water fish such as crucian carp, bream, and silver carp.

fishing tackle

Bomb hook, also known as explosive hook, is a group of hooks, commonly known as mother-child type, bean cake hook, and flying hook. A bomb hook is usually made up of six hooks, with nylon braided line used as the leader. It is primarily used to catch larger fish by casting a fishing rod and sinking the hook to the bottom. It is an effective fishing hook. It is deeply welcomed by many fishing enthusiasts in wide-ranging and deep natural waters such as reservoirs and lakes.
Sleeve: This hook type has no barb. The hook point is sharp, the handle is long, the hook is thin and light, suitable for small fish species that suck and feed, fast fishing and quick retrieval, often used for fishing white croaker, small white barbel, etc.
Floor Hook

In deep-sea or near-shore trolling and bottom fishing methods, a steel plate is used as a bait and lead weight. Its designs are varied and colorful. Its appearance in water can greatly attract sea fish, and the triple-barbed hook it uses has three hook points, which greatly increases the potential for catching fish. It is suitable for fish such as albacore, bluefin, and white marlin.
Competitive Hook

Due to the lack of barbs and the shortness of the hook point, it is easy for inexperienced anglers to lose the fish, but it is the future direction of fishing. Because the hook without barbs can quickly remove the fish without causing too much pain to the fish, which reflects the humanitarianism.
