What food does mussels eat?
The food of mussels is mainly unicellular algae, protozoa and organic debris, such as rotifers, flagellates, green algae, scenedesmus, navicular algae, dinoflagellate algae, quadrangular algae, spindle diatoms, cladosporium, crustacean debris and plant leaves.
Diatoms are mainly digestible.
Mytilus can't actively chase food, but depends on the opening and closing of mussels. The oscillation of cilia and gill cilia in the mantle causes water flow, and food enters the mussel body with the water.
Food enters the coat cavity with water, and the particles move up along the gill filaments to the base of the gill and then forward to the lips. After being selected by the lips, the small particles enter the mouth, the large particles move backwards from the edge of the inner gill, enter the capsule at the junction of the two gills to the back end, and the two shells are slammed out of the body.
Do mussels have pearls?
Mussels have pearls.
However, not every mussel has pearls, and it is not easy for wild mussels to grow pearls. The formation of pearls requires external insects or small grains of sand to enter the mussel. After a long time, mussels secrete nacre and wrap worms or small grains of sand for many years to form pearls. Natural pearls are generally the best, and cultured pearls are cheaper.
How to clean mussels?
The first step: clear water culture
After buying mussels, don't cook them in a hurry. You can put them in clean water, put some salt in the water first, and then cook them for about two to three days.
Step 2: Cut and get the meat.
Take out the cultured mussels and rinse them with clean water.
First cut a gap along the edge of the clam shell with a knife, then insert the knife along the gap and pry it open.
After the mussel shell is opened, separate the mussel meat from the mussel shell, dig it out and put it in the basin.
Step 3: Choose the meat.
Remove the grayish yellow cheeks and the mud intestines at the back first.
The blue dirt in the intestine should be thoroughly removed. Many people use the method of squeezing, but the squeezing is not clean.
Because only some dirty things near the holes can be squeezed out, but the dirty things in the whole mussel intestine can't be squeezed out.
