CATDOLL : CATDOLL: The reason why fried clams release a lot of water

The reason why fried clams release a lot of water

1. The excessive water secretion of clams is related to the salinity of the water during storage.

2. Razor clams are very sensitive to seawater concentration. When the concentration is too low, they will balance the salinity in their nuclei by absorbing a large amount of seawater. At the same time, they will also absorb water to increase their weight. In addition, their taste will become dry and tasteless, and they are more likely to die than normal seafood. Taking razor clams as an example, the standard breeding salinity is 18‰. If 500 grams of live clams are cultured at 9‰ salinity for 8 hours, the weight will become about 600 grams, an increase of more than 20%.

3. If the clams you bought release a lot of water during the cooking process, it is most likely caused by too low salinity during the breeding or selling process. Such clams must be cooked immediately after purchase, otherwise they will be more likely to die and deteriorate. It is recommended that you touch the belly of the clam with your hand when buying clams. If it is a little swollen, it may be farmed under low salinity, and it is normal to be firm.

What is the temperature and salinity of yellow croaker?

The temperature and salinity of yellow croaker are 20°C, the water temperature is 12-15℃ in summer, 18-19℃ in winter, and the salinity is 24-26%. Lobsters can generally survive for a week. In the case of non-muddy water, the water can be changed every three months. Because Australian lobsters are vigorous and active, it is best not to mix them with other seafood except crayfish. Concentrate on the development of certain fish, shrimps, shellfish and echinoderms (such as sea cucumbers) with higher economic value, with a shorter production cycle and higher yield per unit area. According to the breeding pairs, it is divided into marine aquaculture such as fish, shrimps, shellfish, algae and marine treasures. Among them, marine aquaculture of shellfish and algae develops rapidly: shrimp, fish, and marine treasures of mollusks are relatively weak. According to spatial distribution, it is divided into marine aquaculture such as sea mudflats, harbors and shallow seas. According to the degree of intensiveness, it is divided into rough breeding (including care and management), semi-intensive breeding and intensive breeding, with rough breeding as the main one. Left-mouthed fish: The water temperature is about -2℃, the salinity is 24-25%, it can be fed for up to 15 days, and the water needs to be changed once a week.

Scallops, scallops, mussels, and conchs: water temperature 0℃, salinity 18-20%, can be placed for up to 3 days, and are generally fed with running water. There is generally no taboo on mixed culture of these shellfish, but because of their small size, they are placed separately. Grouper, grouper, humphead grouper, mouse grouper, tiger grouper and other grouper materials: water temperature around 20℃ (use a thermostat in winter), salinity 24-26%, generally change water once a week, except for grouper, the rest can be mixed cultured. Geoduck: water temperature is about -2℃, salinity 24-25%, generally can be stored for 5 days, local hunger average water change every 2 days, can be mixed cultured with left-mouthed fish. California bass: water temperature 23-28℃, although the origin of California bass is pure fresh water; but as long as the salinity is kept below 10%, it can generally survive for 20-30 days, change water once a week, and can be mixed cultured with other fish species. Live abalone: ​​water temperature 12-15℃, salinity 10-12%, can be kept for up to 15 days, water is changed every 5 days on average, and usually fed alone.

Small green dragon (crayfish): water temperature 17-18 ℃, salinity 24-26%, generally can survive 3-4 days. Can be mixed with lobsters.

Turbot and knife fish: Water temperature is 18-19℃, salinity is 16-18%. They can be fed for up to 15 days, and the water should be changed once a week. The two can be raised together.

Flower crab, Dungeness crab, swimming crab, crab with roe: water temperature 17-19℃, salinity 23-24%, generally can survive 7 days, all crabs can be mixed

Clams and razor clams: water temperature 13-15℃, salinity 12-15%, can survive for about 5 days, generally fed with flowing water, and there is generally no taboo on mixed breeding of these shellfish, but because of their small size, they are placed separately.

Sturgeon, longspined fish, river shrimp: water temperature 12-15℃, salinity 0. Since sturgeons are more aggressive, they need to be fed alone, while other species can be raised together.

Prawns, mud shrimps, snail shrimps, and grass shrimps: water temperature 18-19℃, salinity 16-18%, can survive for 1-2 days at most. Since shrimps can easily deteriorate the water quality, the water must be changed every other day. If dead shrimps are found in the pool, they must be removed immediately. Since the hotel feeds them in large quantities, they are generally fed individually.

Left-mouthed fish: The water temperature is about -2℃, the salinity is 24-25%, it can be fed for up to 15 days, and the water needs to be changed once a week.

Scallops, scallops, mussels, and conchs: water temperature 0°C, salinity 18-20%, can be kept for up to 3 days, and are generally fed with running water. There is generally no taboo on mixed breeding of these shellfish, but because of their small size, they are kept separately.

Raw materials for grouper, grouper, humphead grouper, mouse grouper, tiger grouper and other grouper species: water temperature is about 20℃ (use a thermostat in winter), salinity is 24-26%. Generally, the water is changed once a week. Except for grouper, the rest can be mixed.

Geoduck: The water temperature is about -2℃, the salinity is 24-25%. It can generally be stored for 5 days, and the water is changed every 2 days on average. It can be raised together with left-mouthed fish.

California bass: Water temperature is 23-28℃. Although the native place of California bass is pure fresh water, as long as the salinity is kept below 10%, it can generally survive for 20-30 days. The water needs to be changed once a week and it can be mixed with other fish species.

Live abalone: ​​water temperature 12-15℃, salinity 10-12%, can be kept for up to 15 days, water is changed every 5 days on average, and usually fed alone.

Live sea cucumbers: water temperature is around 15°C, salinity is 10-22%, can be kept for up to 3 days, with water changed every 2 days on average, and are generally fed individually.

Clams, conches, clams, and swan eggs: the water temperature is 10℃, the salinity is about 12%, and they can be kept for up to 5 days. They are generally fed with running water, and there is generally no taboo on mixed breeding of these shellfish, but because of their small size, they are placed separately.

Advantages of marine aquaculture:

Focus on the development of certain fish with higher economic value,

The temperature and salinity of yellow croaker are 25℃, while for African crucian carp and colorful cloud eagle: add more salt or sea crystal, no ice is needed in winter, and the salinity should be measured beside the car when changing water. This fish is a tropical fish, and the water temperature should be between 18-20°. Loach, yellow eel, and moon snakehead: change water frequently, use pure tap water, and it is strictly forbidden to breed with dirty water or circulating pool water. The water in the circulating pool has salinity. Don't let the water temperature be too low, keep the water temperature at 16-20°. In winter, the water temperature should be specially controlled, and in summer, pay attention to adding a little ice to keep the temperature balanced. Note: If the activity of loach and yellow eel is found to decrease, add a small amount of ginger slices to stimulate to increase the activity. Hairy crab: The water temperature is kept at 15-16°, and the water in the sales pool must be kept clean and small, just enough to submerge the crab eyes. Add a little sea water or glucose in summer to increase the activity.

Osmanthus fish, pearl spot, freshwater melon, yellow snapper: pay attention to salinity, the water temperature should be a little cooler, and the salinity should be around 4-7° (Note: yellow snapper does not need salinity). Lufan Bridge

Grass carp and silver carp: Use clean tap water, add a little salt, no ice in winter, the water temperature should be around 15° (Note: For grass carp, keep the temperature and add more ice)

Sturgeon: It is strictly forbidden to raise it together with grouper (mutual infection), the salinity is about 10°, the water temperature is about 18°, and the water quality is clean.

Be careful when raising artificial plums, natural plums, and yellow plums together to prevent them from infecting each other.

Among freshwater fish, scaled fish and scaleless fish need to be farmed separately, because scaled fish need to be sterilized with salt, while adding salt to scaleless fish will cause the mucus on the surface to fall off and the epidermis to ulcerate.

Yellowtail, also known as silver carp, is a common freshwater fish. The ideal water temperature range for yellowtail is

20℃-26℃, water temperature that is too low or too high will affect their growth and health. Generally speaking, the temperature controlled between 22℃-24℃ can make the growth of yellow croaker smooth.

Yellow croaker has a low requirement for the salinity of water bodies, and Zhaobiku does not like high-salinity water bodies. For yellow croaker, the ideal salinity should be controlled between 0.1% and 0.5%. Too high or too low is not conducive to its growth and health. It should be noted that yellow croaker is different from other freshwater fish and cannot be directly placed in seawater, because high salinity in seawater will cause harm to its life and health.

The temperature range that yellow croaker can adapt to is 15℃-25℃, and the most suitable temperature is about 20℃. Yellow croaker has relatively low requirements for salinity. It is generally adapted to salty and fresh waters. It can grow in salinity between 0-5‰, but the most suitable salinity is 0-2‰. It should be noted that different yellow croaker varieties may have slightly different requirements for temperature and salinity, so when raising them, it is necessary to adjust according to the characteristics of the specific variety.

Yellow croaker is a common tropical fish in spring, belonging to the family of carp. Yellow croaker usually lives in warm ocean waters at a depth of about 30 meters. In such waters, the water temperature is generally between 24°C - 28°C, and the salinity is generally 30ppt - 35ppt. In such a marine environment, yellow croaker grows faster, grows healthily, and can produce delicious meat. Their bodies are silver-gray, and there are obvious yellow hail-colored triangular markings on the sides, hence the name yellow croaker. Yellow croaker is one of the common ingredients on our daily tables, and Lao Senfan is very popular because of its delicious taste.
