Why does sea bass have so few bones in blackfish? And silver carp carp has a lot of bones?

Why do some fish have more bones and some have less? Because of the number of fish bones, to a certain extent, it reflects the evolution of fish. Evolution is mainly due to environmental factors, for example, fish living in high water pressure generally have small spines, so deep-sea fish have small spines.

Marine fish are more advanced, so there are relatively fewer spines, and freshwater fish are lower grade, so there are more spines.

Freshwater fish have many small spines, which are intermuscular spines, which are distributed in the small bones in the septum on both sides of the vertebral body, and their number will gradually decrease as the fish evolves until they disappear. Carp such as carp, crucian carp, silver carp, grass carp and other carp have a low degree of evolution and many small spines. Sea bass, freshwater pomfret, mandarin fish.

Catfish, salmon trout, tilapia.

Fushou fish), black fish, catfish, etc., have a high degree of evolution and have no small spines. In addition, the difference in meat quality is also related to intermuscular spines.

Among the marine fish, hairtail, mackerel, pickled wolf, yellow croaker, grouper, and dragon fish are commonly eaten along the coast.

There are fewer spines such as treasure fish, and fewer deep-sea fish bones are suitable for making fish steaks, fish burgers, Western food, etc. Fish with fewer spines are suitable for braised and steamed, steamed sea bass.

Braised hairtail fish, delicious and nutritious.

Fish with more small spines are more suitable for frying, grilling, and grilled crucian carp in the night food stalls, which are particularly attractive, charred on the outside and tender on the inside, and the meat is delicious. Finally, smoked fish is also a good choice, crispy yellow croaker, with an endless aftertaste.

One. 2. The most beautiful thing about this fish is the abdomen with soft edges, and its swim bladder is particularly fat, and it is a precious fish belly after drying.

3. Catfish is rich in protein and carbohydrates.

Calcium, phosphorus, niacin, vitamins A, B, B12 and many other vitamins and trace elements.

It is a good nourishing and nutritious product.

Sea bass is a fish that has fewer bones.

The perch has fewer bones, only a relatively large main spine, which runs through the whole body of the perch, and contains some fine serrations in the perch strips.

Perch is a freshwater fish in China, in the natural ecological growth, predatory birds, carnivorous fish, etc. will feed on perch, among which the fish are man-eating pomfret, podocarp, map fish, etc.

Artificially farmed

1. Pond construction

Choose a place with abundant water sources and fresh water quality to build a pool. Each pond is 5-8 acres, rectangular, and the north-south direction is better. The bottom of the pool is required to be flat, the bottom of the sand and mud, the bank of the pool is firm, and the depth of the pool is 2 meters.

He is to be buried in the inlet and drainage pipes. Farms should have backup units for power generation.

When stocking, the pond should be desilted and disinfected, and 50 kg of quicklime or 5 10 kg of bleaching powder can be sprinkled and disinfected per mu one week before the seedlings. Before putting seedlings, the basic bait of the cultivation pond water should be fertilized, so that the pond water is oily green or brown.

2. Stocking of fingerlings

Perch fry are mostly caught in the sea at present, the spring sea catch fry is about centimeter-4 cm, and the fish will be injured to varying degrees by fishing and transshipment operations, in order to improve the survival rate of aquaculture, the intermediate temporary breeding can be carried out first. It is more convenient to set up 40 mesh cages in the breeding pond for temporary breeding. 2000-3000 seedlings are temporarily raised per cubic meter of water.

For the first 10 days, Artemia larvae or marine freshwater horns, copepods, and then fresh surimi. Fingerlings are cultured to about 10 cm, and the tail is put into the grow-out pond according to the square meter.

3. Bait

The bait is mainly low-value trash fish, and it can also be fed with pellet bait. Each feeding should be less and then more, and then increase the amount of bait after the fish floats up to grab food, and the daily amount of bait is subject to being full and not wasted, and the fish should stop feeding when they do not grab food. The number of bait is 4-5 times a day, and 2-3 times a day in early spring and late autumn when the water temperature is low.

Glutamic acid, glycine.

and alanine. The total amount accounts for the total amount of amino acids in the muscle of sea bass. There are 3 types of pepsin contained in sea bass.
