There are only three species of carps in our country: black locust, spotted plover and moon plague. Spotted turtles are mainly distributed in areas south of the Yangtze River basin, such as Guangdong, Guangxi, Hainan, Fujian and Yunnan provinces. Spotted Turtle (commonly known as the native fish of Guangdong Province) is fragrant and has less fishy flesh and taste, and has a high commodity value compared with Wuhuan (commonly known as the raw fish of Hunan). It is also an important fish for export. The intensive intensive culture technology of the cantharidin pond is introduced as follows.
First, ponds require intensive culture to use earthen ponds as well (cage or cement ponds can also be used for water culture). The pond area is suitable for 1-3 mu. The depth of the pond is 1.5 meters or more. It is better that the pond is more than 50 centimeters above the water surface, and the bottom of the pond is 10 to 15 centimeters thick. The water escape prevention facilities are safe and reliable, and the drainage and irrigation are convenient. The surrounding environment of the pond is quiet. A water hyacinth of about one-fifth of the water is planted in the center or corner of the pond to regulate the water quality and conceal the shade. Around the fish ponds, a fence of about 1 meter is set to prevent fish from jumping off. Before the fishes are pooled, they are sterilized with a quick-lime bottom clear pond and then stored. After the toxicity has completely disappeared, fish species should be cultured.
Second, the stocking of fingerlings in the Pearl River Delta has a large area of ​​cultivation, high stocking density and high yield. Usually, 3 to 5 cm of fingerlings are released from May to June, and large-sized fingerlings of about 10 cm are also introduced. The fish species to be released require the same source, once in sufficient quantities. The species is robust and disease-free, with uniform specifications. If small-sized fingerlings of the current year are stocked, the stocking density is generally 6,000 to 8,000 tails/mu. After about five months of breeding, the average individual is more than 500 grams. The yield per mu is generally 3,000 kg, and the high yield can reach 5000-7000 kg/mu. In addition, some fish species of the next year are released in February to March. After 4 months of cultivation, they are generally marketed from June to July, and then the new fish are raised.
Third, the feed feeding turtles is a typical carnivorous fish, mainly for small fish, shrimp, alfalfa, aquatic insects and other aquatic animals to eat, its food composition changes with body length and different living environment changes . Flappiness is fierce, bulimia, and when food is insufficient, or when the specifications are irregular, and the individual sizes vary greatly, they can eat each other. Therefore, special attention should be paid to the uniformity of stocking specifications in the breeding process.
At present, artificial breeding aphids are mostly fed with fresh fish such as small fish and shrimp, and artificially domesticated and fed with artificial compound feed. In the Pearl River Delta, because of the easy source of small marine fish (chilled fish), it is generally fed with small marine miscellaneous fish, and the feed coefficient is 3.6-4.2. However, we must pay attention to freezing, ensure quality, do not rot and odor, otherwise it can easily lead to illness.
Fourth, daily management
1. Regularly add new water to prevent deterioration of water due to excess feed or excrement.
2, thunderstorm days to prevent the escape of turtles and pools of water.
3. Adhere to the patrol pond, check whether the escape prevention facilities at the water inlet and outlet are in good condition, and repair it in case of damage.
4, do a good job of fresh-keeping feed to ensure that fresh feed does not rot deterioration.
5, feeding to achieve four set: qualitative, timing, positioning, quantitative.
6, do a good job of prevention and treatment of fish diseases: focus on prevention of fish diseases, every 15 to 20 days Quanchiposa a lime water disinfection, and adjust the water quality. The feed fish is disinfected once a week with 1010-6 concentration of quicklime or (1 to 2) 10-6 bleach. If fish disease is found, it must be dealt with promptly.

Curcumin is a yellow pigment extracted from the rhizomes of turmeric and other plants of the ginger family. It is an acidic polyphenolic substance with unsaturated aliphatic and aromatic groups in the main chain. It is commonly used as a meat coloring agent and acid-base indicator, and also has pharmacological effects such as anti-inflammatory and antioxidant.
