In autumn, squid begins to prepare for hibernation. As temperatures drop below 15°C, they become less active and rely on minimal breathing to survive the winter. To support this process, it's important to feed them high-fat foods like mealworms, crickets, and fly larvae. These provide the necessary energy reserves that will sustain them through the colder months.
Proper harvesting is also crucial during this time. As the temperature decreases, squid tend to burrow into the mud. If you're planning to catch them before winter, start by draining some of the water from the pond and carefully remove a layer of mud. Use gentle methods to avoid damaging the squid. Avoid using hard tools like shovels, as they can injure or cut the animals. It's also wise to keep both large and small squid, as larger ones are more fertile and contribute to better spawning in the next season. Some farmers mistakenly keep only large fish for breeding, which is not only inefficient but also scientifically incorrect.
To protect the squid during hibernation, drain the pond water but ensure the soil remains moist. Cover the area with a plastic net to prevent predators like cats and weasels from attacking. In extremely cold weather, take extra measures to insulate the pond. For ponds with good water quality, consider the deep-water overwintering method—maintain a water depth of 50 to 70 centimeters and add aquatic plants or duckweed on the surface to help regulate the temperature and create a stable environment for the squid.
