Appearance feature
A pair of well-developed gills surround the mouth on both sides of the head. It often moves in shallow seas’ upper and middle layers, with a vertical movement range of more than 100 meters. The body is slender and has a long tapered shape. It is Calamari feeds on krill, sardines, silver fins, small male fish, etc. It is also a prey target for ferocious fish. The eggs are matured in batches and produced in clusters. The eggs are encapsulated in colloidal egg sheaths. Each egg sheath contains several to hundreds of eggs, depending on the type.
Amount of Eggs
The amount of eggs laid by different styles is also very diverse, ranging from hundreds of eggs. To tens of thousands. Squid body has two gills as respiratory organs; the body is divided into head, a short neck Chinese squid (commonly known as “squid”), tender meat, dried products called ” squid “, succulent particularly good at home and abroad seafood market prestigious annual output 4–5 tons, the main fishing grounds in the North Bay, Hainan, China, Fujian, southern Taiwan, Guangdong, Hebei Bohai Bay and Guangxi offshore, as well as the Philippines, Vietnam and Thailand offshore, of which the South China Sea, Beibu Gulf, The squid produced in Bohai Bay is the best.
Squid, although it is customary to call them fish, it is not a fish but a mollusc living in the ocean. The body is slender and has a long cone shape with a suction cup at the front. The squid has two gills as respiratory organs; the body is divided into a head, a short neck and a trunk. The body is slender and has a long tapered shape, two of which are longer. In the taxonomy, squid belongs to mollusc door – cephalopods – two gills subclass – Ten wrist purpose animal. Both sides of the head have a pair of well-developed eyes and wrists and feet around the mouth.
Life habits
It is often active in shallow seas’ upper and middle layers, with a vertical movement range of more than 100 meters. Calamari feeds on krill, sardines, silver fins, small male fish, etc., and itself is the prey target of ferocious fish. Eggs are matured in batches and produced in clusters. The eggs are encapsulated in colloidal oocytes. Each oocyte contains several to hundreds of eggs, depending on the species. The amount of eggs produced by different species varies greatly, ranging from hundreds of eggs. To tens of thousands.
Chinese squid (commonly known as “squid”) has an annual output of 40,000 to 50,000 tons. The main fishing grounds are the Bohai Sea, southern Fujian, Taiwan, Guangdong and Guangxi offshore, and the Philippines, Vietnam and Thailand.
Species distribution
It mainly distributed in tropical and temperate shallow seas.
Farming technology
Squid is precious seafood. The sex of squid fry artificially controls the sex change feature of squid. From hatching to 10 months of age, male squid weighs up to 700 grams is Calamari, while female squid is only 300 to 400 grams. Therefore, experts discussing changing most of the squid male so that squid production has dramatically improved.
The primary method to mix the male hormones of the squid with the squid eggs three weeks before hatching (that is, the insemination eggs and male hormones that have not yet shown sexual characteristics mix for incubation), and the hatched small squids can up to 75% male.
Some of the cultivated squids can grow very large, and the meat is tender and delicious.
Plastic bottle farming
Use wild young octopus, put it in a 500ml discarded beverage bottle with fine holes, seal the bottle’s mouth, hang it in series with a rope, and place it in the sea for natural suspension, adding floats at appropriate intervals, the effect is better. The method is simple, but the growth rate of octopus is slow, and it is suitable for breeding in sea areas rich in plankton.
Cement pond farming of Calamari
Using eight cement pools of about 20 square meters and 80 cm deep, the bottom of the pool cover with sea mud of 20-30 cm thickness (50 cm in the centre of the collection) and the sedimented seawater injected. ~50g (average about 40 grams) size of octopus larvae. It is fed once a day in the afternoon, and the bait is small live crabs (2-6g individuals, 300/kg on average) dug from the beach. Indoor light is between 800~1000LX. During the breeding process, the sedimentation seawater change (100%) times a day. As long as the water change in the hot season, the octopus will generally not die. After about six months of rearing, individuals reach typically 50-100g (about 70g on average) before catching. The method is simple and easy to implement, has low technical requirements, and is suitable for small-scale family breeding.
Seine farming of Calamari
Octopuses cultivated by purse nets and dense nets around 3000 square meters in the middle and high tide areas. When the tide is dry, the octopuses hide in the caves. However, the mesh of the fence must be higher than the highest tide level to prevent escape. The method is low-cost and straightforward, but the digging and catching area is extensive and labour-intensive when harvesting.
