CATDOLL : CATDOLL: What are some fish that can survive in both seawater and freshwater?

There are only a few fish that can survive in both the sea and fresh water.

The Chinese sturgeon lives in large rivers and offshore seas. It is a bottom fish that is migratory or semi-migratory. It likes to gather at river mouths from May to June in spring and summer, and swim upstream to the upper reaches of rivers in autumn.

Eels are warm-temperate, downriver migratory fish that migrate from freshwater areas to river estuaries in late autumn and early winter, and follow the currents out to sea for spawning. After entering the sea, their gonads rapidly develop to maturity.

The spawning grounds are in the deep sea waters south of Taiwan, China. The hatched eels drift with the ocean currents, changing from eels to flat lanceolate eels during the drifting process, and then to thread eels before entering the estuary.

Salmon. Salmon mostly lives in the ocean in spring, and enters the river to migrate in autumn for the reproductive season. Throwing away the head is a local common name for fish, but its scientific name is goby. This fish can survive in both seawater and freshwater, and is an annual small carnivorous fish. It has a big head, a big mouth, small eyes, a small spindle-shaped body, and delicious meat. Whether it is made into soup, braised, or stewed with sauce, it is a favorite delicacy. However, if you throw away the fish head when eating this fish, it is equivalent to missing a delicious dish, so people often call it "throwing away the head" fish.

Among many fish species, the mullet is the easiest to catch. Firstly, although the mullet does not form a school, it has a wide range of activities. It can be found almost everywhere, whether it is a spring tide or a neap tide, whether it is deep water or a shallow beach, and whether it is a muddy or sandy bottom. Secondly, the method of catching this fish is very simple. You don’t need to take a boat or go to an island. You can fish anywhere with sea water. The mullet has a strong appetite and its hunting action is fierce. Sandworms, earthworms, small fish, small shrimps, and small crabs are all good baits. Some people even use the fish pieces of the mullet itself as bait, and they will eat them.

The head-throwing fish is a bottom-dwelling fish. It swims and preys at the bottom. It grabs the bait and swallows it quickly. Because of its wide distribution range, it visits deep water, shallow water, reefs, and mud ponds. In view of these characteristics, the following points should be noted in the configuration of fishing gear and fishing group: First, the selection of fishing rods should be combined with hand-sea fishing and both picking and throwing. The equipped fishing rod should be able to fish both near and far, and can be adapted to both deep and shallow water. It is recommended that anglers should be equipped with a hand rod and two casting rods. The hand rod should be a light and hard fishing rod of more than 4.5 meters, which is suitable for fishing near the shore. When the tide is high and there are many fish, using a hand rod is conducive to increasing the frequency of casting, making it convenient to pick fish ashore, thereby increasing the catch. The casting rod can be equipped with two long-distance casting rods of 3.6 meters or 4.2 meters. It is best to use a reel with a large line capacity to meet the needs of long-distance casting. During the process of rising and falling tides, use a casting rod to fish and chase the fish.

2. The fishing line should be matched with a combination of thickness and reasonable matching. The fishing line should be adapted to the characteristics of the head-throwing fish that eat bait fiercely, demand lines fiercely, and have complex bottom conditions. Strong and durable products should be selected, and at the same time, how to minimize the occurrence of line breakage and loss should be considered. The main line of the hand pole is suitable for nylon line No. 5 to No. 7, and the sub-line and branch line are one size smaller respectively. Once hooked, it is better to throw away the hook and sinker, but also to keep the main line, saving time for replacing the main line and increasing the catch. Sea fishing must not be done with one line to the bottom, and the hook is directly tied to the main line. In this way, once the hook is hooked, it is most likely to break the main line and delay the fish. The main line of the casting pole can choose a strong fishing line of No. 5 to No. 6. The strong fishing line of No. 6 to No. 7 is the sub-line, and the hook-tying line generally chooses a strong fishing line of No. 3 to No. 5, with 3 to 5 hooks tied on it. This line group seems to be an unreasonable reverse-pull bull-style line group combination, but it is more conducive to increasing the casting distance, because the casting distance is far and the main line is long and generally will not be easily broken.

3. Use a suitable weight of fishing sinker, preferably a through-hole sinker. Fishing for head-throwing fish is a bottom-dwelling fish, so bottom fishing must be implemented. Whether it is a casting rod or a hand rod, there is no need for a float. Only by the feel and the change of the rod tip can we judge whether the target fish has taken the bait and been hooked. Therefore, the choice of fishing sinker is very important. It is not good to be too light or too heavy: first, it does not match the elasticity of the rod body, which directly affects the accuracy of the casting distance and the landing point; second, it will affect the relative stability of the hook bait in the water; third, it will affect the state of the fishing line and the reaction of the fishing group when the fish swallows the hook bait. Therefore, the selection of fishing sinker should be based on the principle that the fishing rod can give full play to its elasticity under the condition of weight. This can maximize the casting distance and avoid damage to the fishing rod. According to my practice, it is OK to use a dead sinker or a through-hole sinker with a hand rod to fish for head-throwing fish, but it is best to use a through-hole sinker because it can increase the sensitivity of the head-throwing fish to swallow the bait and be hooked. Hand rods can generally be equipped with a through-hole sinker of 10 grams to 20 grams. Casting rods can use long rhombus-shaped lead sinkers, which are generally 100-120 grams. At the same time, according to the specific conditions of the fishing waters, several spare sinkers can be equipped in case of emergency.

4. It is better to use a small hook rather than a large one, and a long-handled hook is preferred. The head of a headfish has a big head and a big mouth, so you don't have to be too demanding on the hook. But the general principle is to use a small hook when the fish is small, and a large hook when the fish is big. My experience is that although a large hook can also catch fish, the hook rate is relatively much lower. Therefore, I suggest that it is better to use a small hook rather than a large one, so as to reduce the phenomenon of not catching fish when the rod tip moves and lifts the rod. I usually use a long-handled hook of Maruse No. 11~14, because the headfish is fierce in grabbing food, and using a long-handled hook can prevent the fish hook from being swallowed by the fish, and it is also convenient to remove the hook.

5. Rationally match the fishing group to ensure that the hook is undercover. In view of the benthic characteristics and predatory habits of the head-throwing fish, the requirements of fishing on the bottom should be highlighted in the equipment of the fishing group. The hand rod can be equipped with a double hook under the sinker, with one long and one short hook line, the long one is about 15 cm and the short one is about 10 cm. According to the characteristics of the fish, you can also tie another hook to the sinker. When the tide is good and the fish density is high, it can effectively increase the catch. The casting rod can use a fishing group with 4 to 5 hooks on the sinker, or a sub-sinking fishing group. Hang an 80-100-gram mother sinker in front of the branch line, and then tie 3 to 5 hooks evenly, and then wear a 20-40-gram through-heart active sinker on the branch line as a sub-sinker. The activity distance of the sub-sinker is fixed with two space beans, generally set to 15 cm to 25 cm. It is better to set the entire branch line to 1.2 meters to 1.5 meters, and it is better not to entangle the hooks. The advantage of this method is that all the hooks on the fishing group can lie on the bottom of the water, which can significantly increase the fish catching rate. It is one of the most suitable casting fishing methods for catching head fish. It is recommended to prepare several sets of line groups when fishing.

Seven-star perch is also called flower perch. Seven-star perch is a euryhaline fish that can survive not only in seawater, but also in brackish water and even in fresh water. Perch is a typical migratory fish. Whether it is artificially bred or naturally bred, it breeds in seawater. Seven-star perch cannot breed in freshwater reservoirs. Seven-star perch has delicate meat without small bones, tastes sweet and has no fishy smell, is rich in nutrients, and is the most highly rated target fish in the lure fishing world. The deliciousness of perch is deeply loved by foodies, and it is also loved by lure fishing enthusiasts because of its ferocious hunting. However, seven-star perch is cunning by nature. Based on my experience, this article shares the skills of lure fishing for perch. Let's analyze it from the following points:

Things to pay attention to when fishing for bass

Understanding the above important points is related to whether you can catch a bass. Understanding some of the characteristics of bass that are different from other fish can help you catch it better. For example, there are gill knives on the gills of bass. This feature is especially important in the process of bass fishing. When you catch a fish, you should try to lower the lure rod to prevent the bass from using the gill knives to cut the fishing line to save itself when washing its gills. This is also related to the need to choose a good leader line and lower the rod tip when fishing for bass. There are many other points to pay attention to when fishing for bass. Let's start with the habits of bass and learn more about them.

The seven-star perch is a migratory fish that goes to the deep sea to spend the winter after spawning. The hatched young perch enter the estuaries of rivers and grow in the spring. Perch is a carnivorous fish. The spotted perch feeds on many kinds of things, such as small fish and shrimps, and likes to hunt live food that can swim. The perch has teeth in its mouth and sharp gill knives on its gills. The seven-star perch not only ambushes its prey like the mandarin fish, but also chases its prey like the black carp. The seven-star perch is gregarious, and often after catching a fish, it will continue to catch fish.

Marine fish that can live in fresh water

There are only a few fish that can survive in both the sea and fresh water.

The Chinese sturgeon lives in large rivers and offshore seas. It is a bottom fish that is migratory or semi-migratory. It likes to gather at river mouths from May to June in spring and summer, and swim upstream to the upper reaches of rivers in autumn.

Eels are warm-temperate, downriver migratory fish that migrate from freshwater areas to river estuaries in late autumn and early winter, and follow the currents out to sea for spawning. After entering the sea, their gonads rapidly develop to maturity.

The spawning grounds are in the deep sea waters south of Taiwan, China. The hatched eels drift with the ocean currents, changing from eels to flat lanceolate eels during the drifting process, and then to thread eels before entering the estuary.

Salmon. Salmon live mostly in the ocean in spring and migrate to rivers in autumn to breed.

Salmon are born in fresh water, grow up in sea water, and return to fresh water to spawn when they mature.

There is a species of eel in Australia that is born and raised in the sea, but they swim back to live in fresh water.

The sea bass we usually eat, such as "green strips", live at the mouth of the river and are neither salty nor bland.
