Squid is a highly valuable marine creature, with its entire body offering numerous culinary and commercial uses. The meat is tender, free from intermuscular punctures, and has a high consumption rate. It can be enjoyed as sashimi, fried fillets, smoked, or canned products. Additionally, various parts of the squid—such as the tentacles, fins, liver, mucus, bones, gastrointestinal tract, and notochord—are used in different cuisines. Notably, dishes made from processed squid eggs are celebrated as premium nutritional foods worldwide. The tentacles, bones, and skin can even be transformed into glue, while the leather is used for high-quality leather production. Studies suggest that squid contains 10 to 15 times more anti-cancer compounds than sharks, making it beneficial for cancer prevention, gastric health, and even reducing hair loss. In recent years, the artificial breeding of eel has gained momentum, and the aquaculture industry is optimistic about its future potential.
Carp is another promising species due to its large size, long lifespan, high survival rate, fast growth, strong disease resistance, and adaptability to artificial conditions. Under controlled feeding, fry can reach 0.7 to 1 kg by the end of their first year, 2 to 3 kg by the second, and up to 5 kg by the third. Multiple carp species have been successfully bred and farmed, including small carp, paddlefish, austerichthys, Siberian gudgeon, and hybrid varieties. These are raised in both still and flowing water systems. However, despite their potential, these fish are not yet widely cultivated, limiting the availability of eel-based products.
To enhance squid farming efficiency, new techniques have been developed. First, for calm water cultivation: select ponds of approximately 1,300 square meters with a depth of 1.5 to 2 meters, using clean water sources like reservoirs or rivers. Disinfect the pond with quicklime a week before stocking, avoiding bleach. Stock fingerlings over 15 cm long at a density of 500–700 per acre, along with oysters and squid. Soak the seedlings in 3% saltwater for 20 minutes before placing them in the pond. Install feed tables in the deepest part of the pond, especially during summer, with one or two stations per acre. Use catfish compound feed with over 35% protein, feeding three times daily (6 AM, 1 PM, 4 PM) and once at night (11 PM), at a rate of 2.5% to 4% of the fish weight. Maintain water clarity above 40 cm, and when water temperature exceeds 28°C, stop feeding and increase fresh water supply. Start aeration at noon on sunny days.
For running water cultivation: build ponds between 50–100 square meters, with circular, square, or rectangular shapes and efficient water systems. Construct each pool in a stepped shape with a depth of 1.5 meters and 80–100 cm at the top. Cover the pond with a steel shed and install film and screens. Use clean, oxygen-rich water, such as reservoir bottom water or aerated underground spring water. Stock 30–40 squid per square meter, adjusting density based on water exchange. Feed specialized squid feed with over 40% protein, granulated according to fish size, and add vitamins and fish oil for balanced nutrition. Feed 4–6 times daily at a rate of 3%, placing food around the walls and reducing water flow during feeding.
Daily management includes maintaining water flow to replace the pond within 1–1.5 hours, monitoring water quality and temperature, and cleaning the pond 2–3 times weekly. Drain half the water each time and remove waste. In summer, use shade nets and increase flow to keep temperatures below 30°C. In winter, cover the pond with black film to prevent frost and reduce water changes.
Disease prevention is crucial. Although carp have few natural predators and rare outbreaks, poor water quality can lead to issues. Regularly disinfect the pond, use special sanitizers, and add antibiotics like furazolidone or norfloxacin to feed to prevent intestinal diseases. In winter, maintain higher water temperatures to avoid white spot disease and fungal infections. Treat trichodiasis, oral filariasis, and tongue cup disease with potassium permanganate (2 mg/L) or copper sulfate (75 mg/L). With proper care, squid farming can become a sustainable and profitable venture.
Smart Locks For Cabinets
