CATDOLL : CATDOLL: How many major categories can squid be divided into?

1. How many major categories can squid be divided into?

A: There are two major categories: Decapoda and Octocapoda. Decapoda has ten tentacles, one pair of which is particularly long and has an inner shell, including various squids; Octocapoda has eight tentacles and no inner shell, which is the octopus. The specific subcategories are as follows:

There are about 350 species of squid in the world, among which the common squid species include needle squid, golden squid, calamari, needleless squid, flame squid, fluorescent squid, giant squid, spotted squid, fine squid, flying squid, etc.

The largest squid in the world is the giant squid, also known as the giant squid, and the smallest squid is the larvae squid.

Squid has long whiskers and a slender body. It is a common mollusk in the ocean. There are as many as 350 species of squid distributed in the vast ocean, making it the most beautiful embellishment in the entire ocean.

There are many types of squid in my country. The East China Sea is rich in Mann's needleless squid, which is abundant in the southern coast of Zhejiang and the coast of Fujian; the Taiwan squid is distributed in the sea area south of the Taiwan Strait, with the waters off Shantou and the Beibu Gulf as its spawning grounds.

2. How to plant freshwater squid fry?

Cultivation method: It likes mild light. Under warm light, it can accumulate some nutrients through photosynthesis. However, it needs to avoid exposure to the sun, as too strong light will also threaten its health. Generally speaking, it is more suitable to be between 15 and 25 degrees.

3. Can squid and cuttlefish be farmed artificially?

Squid and cuttlefish can be farmed.

1. Artificially cultivated cuttlefish

Squid (commonly known as cuttlefish) is expensive in the market. Its meat is thick and delicious, and it has high nutritional and economic value. However, due to overfishing in recent years, natural resources have declined significantly.

The technology of artificially breeding cuttlefish is an international problem. It was not until 2004 that artificial breeding of cuttlefish was first successfully achieved in Ningbo, China. The breeding technology and scale still need to be improved.

2. Artificially farmed squid

Some artificially cultured squids can grow very large, with tender and delicious meat. Squid is a valuable seafood. The characteristics of squid sex change are artificially controlled. From hatching to 10 months old, male squids can weigh up to 700 grams, while females only weigh 300 to 400 grams. Therefore, experts are exploring ways to change most squids into males to significantly increase squid production.

Additional information

The provincial aquatic seed project "Reproductive Regulation and Seedling Breeding Technology Development of Tiger-spotted Cuttlefish" and the provincial public welfare technology research agricultural project "Research on Reproductive Regulation and Seedling Breeding Technology of Pseudo-order Cuttlefish" have passed the acceptance of the expert group organized by Zhoushan Ocean and Fisheries Bureau and Zhejiang Ocean University.

After two years of research, the team successfully used wild squid parents to hatch artificially bred false squid and tiger squid larvae, with a hatching rate of over 90% and a seedling survival rate of over 60%. Both species have the characteristics of fast growth, low leftover food, high survival rate, short breeding cycle, and suitability for large-scale breeding.

During the research period, the project team cultivated more than 64,000 fertilized eggs of tiger-spotted squid and Pseudo-eye squid, more than 57,000 tiger-spotted squid and Pseudo-eye squid larvae with a body length of 1 cm, and more than 33,000 tiger-spotted squid and Pseudo-eye squid seedlings with a body length of more than 3 cm.

In addition to the research base, breeding is also being promoted in Ningde, Fujian and other places. The growth rate of the two types of squid is extremely fast, and they can grow to more than 500 grams in 4 to 5 months. They can grow even faster in waters with high temperatures, which greatly shortens the time to market.
