CATDOLL : CATDOLL: Can sea bass be kept in fresh water?

Bass mostly lives near the mouth of rivers and streams near the coast. It is a brackish and freshwater fish. The fish is very large, with the largest one weighing more than 20 kilograms. The fish has a large egg-carrying capacity, and some parent fish can carry more than 100 million eggs.

Bass is a typical carnivorous fish with a varied diet. It likes to eat anything that lives in the water, whether it is a small loach, shrimp, small fish, sandworm or squid. It is ferocious and greedy. Because of its greed, it does not hesitate or doubt when biting the hook. When it finds bait to eat, it rushes up and swallows it in big mouthfuls, so it is relatively easy to fish.

The meat of sea bass is tender and plump, with few bones and no fishy smell. It is a precious edible fish and restaurants serve it as a high-end dish.

Sea bass, also known as spotted sea bass and seven-star sea bass, belongs to the order Perciformes and family Liparidae in taxonomy. It is also called sea bass because it breeds and grows along the coast, unlike the California sea bass and sweet-scented perch that grow in freshwater. Sea bass is one of the four famous fish in the Xijiang River, including sea bass, croaker, mandarin fish and bream. It has firm and delicious meat and rich nutrition. Every 100 grams of fish contains 17.5 grams of protein, 3.1 grams of fat and multiple vitamins.

1. Living habits and growth conditions of sea bass

Perch live in shallow sea estuaries and are suitable for wide salt. The fry are hatched in seawater with a salinity of about 22‰, then swim upstream to the estuary where salt and fresh water meet and live. They can enter fresh water to forage and grow, but most adult fish live in salt and fresh water. Perch is a ferocious carnivorous fish with a large appetite. The food intake can reach 5%-12% of its body weight at a time. The intensity of predation is the strongest in spring and summer. The fry use copepods and mysid shrimp as bait, and when they grow to 10 cm in length, they prey on small fish and shrimp. Perch grows quickly. The breeding period is generally from November to January of the following year. The fry grows to 25 cm in length and weighs 0.5 catties by the end of the year. The 6-year-old fish can reach 0.8 meters in length. The largest individual can reach 1 meter in length and weigh 15-20 kilograms. Artificially cultivated perch grows faster, usually reaching more than one catty in 280 days of cultivation. Perch can forage and grow normally when the water temperature is above 14℃, and can naturally overwinter in this area.

Bass can grow in fresh water, but according to its natural habits, it is better to choose brackish water areas reached by tides. Fish at river mouths and reclaimed areas are the best. The water salinity can be below 5‰. The growth rate will be slow if it is farmed in waters with too high salinity.

2. Activities and foraging of sea bass

1. Although bass have the habit of jumping and dancing in the process of fighting, it is limited to within 10 feet of the shore, and the jump is even more powerful when seeing people. However, more than 10 feet away, it will sink desperately after being hooked, and it is the kind of long air bag. At this time, it is recommended to hold the fishing rod high to prevent it from running into the fishing range of others. In addition to avoiding the entanglement of the fishing line of the neighboring angler, you can also know exactly where it slips away.

2. Although the skin of the bass' mouth is weak, it is very resilient, and it is rare for the hook to "cut" the skin and cause the fish to escape. Moreover, its gill cover is soft and slippery, so you may want to hold the fishing rod high for a long time and force it to perform a diving action. This action does not help it to break free from the hook, but will make it dive into the water for a long time, which is very risky.

3. In addition to its fast diving and diving speed, perch also has the habit of sprinting to the left and right.

4. Bass are very gentle when taking bait. If the main line is not tightened when assembling the hook, it is difficult to detect the fish.

5. The general way for bass to take bait is to flick it frequently. Whether it is a five-hook fishing rig or a double-hook fishing rig, you need to increase your mental concentration and grasp the opportunity to fish at any time, while avoiding having your fishing rod pulled away by the bass.

6. Bass live in groups. If you see bass jumping into the water or chasing food at the same spot, it means there is a group of bass here, not just one.

The length of perch can reach 60 centimeters. It is ferocious and carnivorous. There are many varieties. It is distributed along the coast of my country and in the estuaries of rivers and seas. In recent years, my country has introduced California perch (referred to as California perch) from the United States to breed in coastal and southeastern provinces. This perch is omnivorous, grows fast, has few diseases, is highly adaptable, and is very easy to catch. It has become one of the main target fish for fishing in coastal and inland my country.

Fishing for perch in coastal areas and estuaries can be done by hand fishing, hand rod fishing, or casting rod fishing. When hand fishing on a boat, you can pull the line up and down at a depth of 20 to 60 meters to lure the perch to take the bait. Once you feel that the hand feels heavy, you can pull it up suddenly to make the hook pierce the fish's mouth, and then slowly pull the line up. If you feel that the struggle is strong, you can slowly release the line, but do not let it go suddenly. The line is generally 5 to 6, the hook is 7 to 10, and the bottom weight is used, with 3 to 5 hooks hanging. The bait is sandworms, white shrimps, and small fish for good results.

When fishing with a hand pole on a boat, you should lift and release the pole, just like hand fishing. Since the pole is short and the line is long, if there is no release device, you still need to lift the line by hand after you catch the fish. It should be noted that the line should not be tangled during the lifting process, so that it will be convenient and time-saving when you fish again, and the line will not be damaged and the fish will escape. In contrast, it is of course best to use a casting rod to fish for bass, and a long casting rod of more than 3.6 meters and a grape hook will have the best effect. Since there are large bass weighing 40~50 kilograms in the sea, it is difficult to adapt to hand fishing or hand pole fishing, and it is easy to cause the danger of dragging people into the water. Casting rods have long lines and can be reeled in and released, which is much safer. As for local bass and California bass in coastal and inland artificial breeding waters, due to annual pond cleaning, the largest individual does not exceed 2~4 thousand, and is generally 1~2 kilograms. Therefore, you can use a hand pole or a casting rod. Hanging fishing and trolling fishing are especially good. The bait is mainly meat bait.
