Scutellaria baicalensis, commonly known as yellow crickets or field plovers, belongs to the family Blastocystidae and is widely found in inland water bodies across China, particularly in the Yangtze and Pearl River basins. These creatures have a slender, snake-like body with a rounded head that tapers toward the tail. Their eyes are small, but their sense of smell and hearing are highly developed. They are nocturnal, often burrowing into muddy, humus-rich substrates and preferring acidic water environments. Yellow crickets are temperature-sensitive animals, thriving best between 15°C and 30°C, with optimal growth occurring between 24°C and 28°C. When water temperatures drop below 10°C, they enter hibernation, slowing their metabolism and relying on stored nutrients. Conversely, when temperatures exceed 32°C, they become less active and seek deeper waters to avoid heat stress. Their growth period typically spans from May to October, with the fastest development occurring between June and September. These animals are known for their slippery nature and tendency to escape, especially when food is scarce, during thunderstorms, or when water quality deteriorates. They can leap out of ponds by pushing their heads upward along grasses or using nearby structures like walls or drainage channels. In severe cases, entire populations may escape, leading to breeding failures. Therefore, effective anti-escape measures must be implemented throughout the rearing process. As omnivores, yellow crickets feed on a variety of aquatic organisms, including insects, zooplankton, snails, small fish, and algae. They also consume organic detritus and some phytoplankton. They prefer fresh food and are resistant to hunger. In captivity, they can be fed a mix of live foods such as fish, shrimp, snails, and mealworms, as well as commercial feeds like pellets or extruded products. For successful farming, it is important to select suitable ponds with clean, flowing water, good drainage, and convenient access. Ponds should be 1.5 meters deep and cover an area of 3 to 5 acres. Net cages made of high-quality polyethylene are commonly used, with sizes ranging from 2m x 6m x 1.5m to 3m x 5m x 1.5m. The mesh size should be appropriate for the size of the juvenile crickets to prevent escape. Cages are typically placed on bamboo rafts, with the top of the cage 60–70 cm above the water surface. Cages should be spaced at least 1.5–2 meters apart, with no more than 15–20 cages per mu. Before introducing seedlings, the cages should be soaked in water for over a week to allow algae to grow on the nets, making them smoother and preventing injury to the crickets. In addition, planting aquatic plants like water hyacinth or duckweed in the cages can help regulate water temperature, providing cooling in summer and warmth in winter. However, these plants can sometimes host pests that damage the vegetation and increase harmful substances like nitrites and ammonia in the water. To manage this, a "sewage show" (likely a pest control spray) is usually applied every two weeks to maintain healthy plant growth and water quality.
