CATDOLL : CATDOLL: How to farm squid

Cuttlefish farming technology

1. Cage culture

1. Cage setting

It can be cultured in cages (3.94m×1.82m×0.9m, the mesh is smaller than the individual fish, and a net cover is required to prevent the squid from escaping. Squids are mostly cultured in harbors with quiet waves, and the suitable water temperature is 15-23℃. Under normal circumstances, they are mostly cultured in spring, summer (June and July) and autumn (October-December).

2. Seedling capture

Squid fry caught in cages are the most suitable, but those caught from bottom drag nets can also be used. The amount of fry to be released varies depending on the water temperature and water flow. Use large cages to release 36-42 kg of fry per cubic meter, and small cages to release 25-30 kg of fry per cubic meter. To prevent the fry from killing each other, the same batch of fry should be released, and the fry should be put into the cage after they have eaten their fill.

3. Bait placement

Cheap small fish and shellfish can be put in, frozen small fish can also be put in, but they must be fresh. If there are too many leftover baits, it is better to reduce or stop feeding for 1-2 days. Leftover baits will cause water pollution. If feeding is stopped for more than 3 days, it will cause cannibalism. The feeding behavior is irregular when the water temperature is around 13℃, and the squid will not eat when the water temperature is below 7℃.

4. Survival rate The survival rate of caged seedlings is 70% to 80% after 2 months of culture, while the survival rate of fished seedlings is about 50%. The mortality rate of seedlings in cages is 20% to 30% after 15 days, and then gradually decreases. After 15 days of culture, the squids are divided into three sizes: large, medium and small, and raised in different cages. Clean the cages every 15 days in spring and autumn, and every 30 days in winter.

2. Plastic bottle farming

According to reports, some fishermen use wild young squids, put them in 500ml discarded beverage bottles with fine holes, seal the bottle mouths, hang them in a series with ropes, and place them in the sea for natural hanging. They also add buoys at appropriate intervals to achieve better results. This method is simple, but the squid grows slowly and is suitable for breeding in sea areas rich in plankton.

3. Pond culture

According to reports, a farmer uses 8 cement pools of about 20 square meters and 80 centimeters deep. The bottom of the pool is covered with 20 to 30 centimeters thick sea mud (50 centimeters thick in the center of the pool), and the settled seawater is injected. A total of 10 to 50 grams (average of about 40 grams) of squid larvae dug from the beach are put in. Feed once every afternoon, and the bait is live crabs dug from the beach (2 to 6 grams per individual, an average of 300 per kg). The indoor light is between 800 and 1000LX. During the breeding process, the water is changed with settled seawater (100%) times a day. As long as you pay attention to changing the water during the high temperature season, squid generally will not die. After about 6 months of breeding, the individual before catching generally reaches 50 to 100g (average of about 70g). This method is simple and easy, and the technical requirements are not high. It is very suitable for small-scale family breeding.
