The largemouth bass is native to the United States and is a freshwater fish. Its body surface is light yellow-green, and its back is black-green. Its identification mark is a black horizontal stripe on each side of the body, extending from the head to the caudal fin.

The body of California bass is elongated and flat on the side, slightly fusiform, with an oval cross section. The ratio of body height to body length is 1:3.5-4.2, and the ratio of head length to body length is 1:3.2~3.4.
The head is big and long. Eyes are large and prominent. The muzzle is long, the mouth is upper, the mouth is large and wide, and it is oblique. It exceeds the back edge of the eye and the jaw can stretch. The jaws, palatine bones, and vomeres have complete comb-like teeth, which are many and small, and of the same size.

The whole body is covered with gray silvery white or light yellow small comb scales, the back is black and green, and the sides are blue and green. There are often black markings on the side of the body along the side line, from the snout to the base of the caudal fin arranged in a strip, and the abdomen is gray and white.
The first dorsal fin has 9 hard spines, the second dorsal fin has 12 to 13 fin rays, the anal fin has 3 hard spines, 10 to 12 fin rays, and the pelvic fin has 1 hard spine and 5 fin rays.
It is naturally distributed in the freshwater basins from central and eastern North America to northern Mexico.

Life habits:
In the natural environment, largemouth bass prefers to inhabit in shallow water areas (1 to 3 meters water depth) in a still water environment with low turbidity and sandy mud, low turbidity and aquatic plants, small streams in swamps, and stagnant water in rivers. Areas, ponds, etc., the Youxi group lives in the clear, slow flowing water. Generally active in the middle and lower water layers, often hiding in underwater rocks or vegetation.
Not tolerant to low temperatures, it can survive in the water temperature range of 1~36℃, start to eat above 10℃, and the optimum growth temperature is 20~30℃. The amount of dissolved oxygen in water is required to be above 1.5 milligrams per liter, which is stronger than that of mandarin fish to withstand hypoxia.
It has the habit of occupying land and the scope of activities is small. The temperament is relatively tame, not like jumping, and easily frightened. Juveniles love to move in groups, while adults are scattered.

feeding habits
Carnivorous fishes are highly predatory and have a large food intake. Adult fish often forage alone, preferring to prey on small fish and shrimp.

How to catch largemouth bass
Largemouth bass like to live in sandy or sandy muddy still water environments, especially in clear water with a slow flow rate, generally in the middle and lower water layers, hiding in aquatic plants, but black bass only works at a temperature of ten. The predation started only when the temperature was higher than the temperature. Seeing the startling of small fishes and shrimps on the surface, the flashing of fish blossoms, etc., it was mostly clusters of sea bass chasing for food. As a carnivorous fish species, black bass eats astonishingly, and even cannibalize the same species.

The fishing rig needs to be composed of about 10-20 grams of bullet lead, retaining beads, crank hook (usually No. 3 hook for bass fishing), and soft bait. The key to the lure largemouth bass lies in the use of fake bait: the length is about 5 to 7 cm, the soft bait can choose the lead-head lead between 1.5 and 5 grams, the 1.5-inch soft insect or the upside-down fishing set.

After the lure is thrown, don't rush to close the line and let it sink for a while. Take up the thread after about 5 seconds, try to keep it at a certain depth, but each time you can change the speed and depth of the thread to try and get it to the bait. Largemouth bass is too "stupid" and easy to be hooked. This is why many Luya novices like it.
