CATDOLL : CATDOLL: Are seafood clams considered wild animals?

1. Are seafood clams wild animals?

It is not considered a wild animal, but it is considered a seafood product.

Clams are farmed now.

There are both wild and farmed

2. Can clams be raised with tap water? How many days does the breeding period last?

answer

Clams generally refer to clams, which mainly live in the ocean. Therefore, they cannot be raised with tap water. Seawater should be used, and a layer of sand should be laid underneath. If there is no seawater, salt can be added to the water to simulate seawater, and it can be raised for several days (30-34g of salt per 1kg of water). The breeding cycle of clams is relatively short, and they usually grow to about 10-16 months, and are captured when they grow to 30mm or larger.

1. Can clams be raised in tap water?

1. The clams people usually refer to are usually flower clams.

2. Clams mainly live in the ocean, so they cannot be kept alive with tap water. Seawater should be used, and a layer of sand should be placed underneath. If there is no seawater, salt can be added to the water to simulate seawater. Generally, 30-34g of salt is added to every 1kg of water, and the concentration of the salt water is controlled between 3-3.4% (usually it can be kept for several days).

3. The feeding method of clams is passive filter feeding. The main food includes unicellular algae such as sieve algae, boat algae, chlorella, and nitzschia, as well as invertebrate eggs, bivalve D-shaped larvae, copepods, nauplii and a large amount of organic debris.

4. Clams can survive normally in seawater with a dissolved oxygen content of 1 mg/L, but when the dissolved oxygen content is continuously lower than 0.5 mg/L for more than 10 days, the clams will die.

2. How many days does it take to cultivate clams?

1. The cultivation cycle of clams is relatively short, generally about 10-16 months, and clams are harvested when they grow to 30mm or larger (in China). If it is in European waters and North America, it is generally 16-30 months, and clams are harvested when they grow to 30-40mm or larger.

2. Clams grow fastest when they are 1-2 years old, and their growth rate becomes slower after 3 years old.

3. Influence of temperature: Clams have a wide range of temperature adaptability and can adapt to water temperatures of 0-36°C. They grow normally in water temperatures of 5-35°C. They grow fastest in water temperatures of 18-30°C. When the water temperature is 44°C, the mortality rate is around 50%; when the water temperature is 45°C, almost all of them die; when the water temperature drops to 0°C, they stop eating; when the water temperature is minus 2-3°C, the mortality rate is around 10%.

3. Are clams freshwater or seawater?

Clams live in seawater and are a kind of shellfish. They are a common shellfish seafood on the market and are widely distributed in the southern and northern seas of China. They grow quickly, have a short breeding cycle, are highly adaptable, and can survive long out of water.
