: Original report from Aquatic Frontier Network, important! The brothers of Dingfeng, Thailand, will launch a new "balanced" shrimp - Dingfeng resists resistance, which has increased its disease resistance by 50%, and its growth rate is 20% slower than Dingfeng's "fast-large" shrimp, but it is more suitable for environmental changes, adapt to temperature differences, easy to cultivate shrimp seedlings, and high yield! In short, it is to "satisfie the needs of most areas of China, meet the needs of most breeders, and meet the needs of most breeding models"!
It is reported that the "balanced" shrimp was independently bred by the Thai Siamese shrimp company and has been bred for 6 years. Thailand Siamese shrimp farming company is affiliated to Thailand Sunanta Group. It is also the parent company of Thailand Dingfeng Aquaculture Co., Ltd. (English name: TOP AQUACULTURE TECHNOLOGY CO., LTD, Chinese abbreviation) which everyone is very familiar with. It is reported that the "balanced" shrimp will be officially supplied to the Chinese market in January next year and reservations have begun to be accepted.
Without further ado, let’s take a look at the true appearance of the Dingfeng-Nailable Shrimp!

has outstanding resistance to disease, with the highest survival rate in the pilot stage nearly 100%
At the beginning of this year, Dingfeng-resistant and anti-shrimp shrimp shrimp sanitary at the same time Breeding tests were conducted in China and Thailand. Judging from the test situation, in the high-density breeding model of Guangdong and Thailand, the seedling density was 136 tails/square and 130 tails/square, and the breeding cycle was 100 days and 97 days, respectively. The unit weight of shrimp was 24 jin and 25 jin, the average tail weight was 20.8 grams and 20 grams, the survival rate was 78.2% and 98.62%, respectively, and the daily weight gain was 0.18 grams and 0.21. In the medium-density breeding model in Tangshan and Thailand, the seedling density is 54 tails/square and 52 tails/square, and the breeding cycle is 95 days and 97 days, respectively, with the unit weight of shrimp produced is 22 jin and 21 jin, with an average tail weight of 22.72 grams and 23.80 grams, with a survival rate of 81.2% and 99.95%, respectively, and a daily weight gain of 0.23 grams and 0.25. Dingfeng-resistant anti-seed shrimp has good survival rates and growth rates in the above two modes, with the highest survival rate being nearly 100%. The excellent growth rate distinguishes it from ordinary high-resistant seedlings, and its growth rate is not slow! (See the table below for details)

Excellent production performance
It is reported that the best egg laying period (using time for shrimp) of this type of shrimp reaches 4 months, and the hatching rate reaches 90%. The female shrimp sold to China now generally has a tail weight of about 50 and a tail weight of about 45 for male shrimp. The number of eggs for the first time is 200,000, and the number of egg laying can reach 400,000 when it enters the peak egg laying period. The total egg laying volume of female shrimp in 4 months can reach 5 million. The maturity rate of female shrimp is 15%, the mating rate is 15%-20%, the mating success rate is 85%, and the hatching rate is 90%. For a shrimp with a "balance system", such data performs very well. (See the table below for specific data)
About Thailand Siamese Shrimp Company and its "balanced" shrimp
Thailand Siamese Shrimp Company and Dingfeng Company are both affiliated to Thailand Sunanta Group. Unlike the Xiangfeng "fast-large" shrimp that is positioned at high and long speed and is aimed at high density breeding models such as factory-based, high-level pools, and small sheds, Thailand Siamese Shrimp Company mainly oriented at the selection and breeding of "balanced" shrimp. In fact, the relevant person in charge of Dingfeng revealed in previous interviews that the group has been doing SPR seed sources, with the goal of selecting and breeding shrimp varieties that are fast, strong and resistant to disease.
Dingfeng began to participate in the selection and breeding of shrimps in 2010, sold shrimps to the outside world in 2015, and entered the Chinese market in 2017. With its outstanding performance in the north and south markets and good market reputation, it has become a big dark horse in the Chinese shrimp market in just two years, and has a high market share in China's fast-sized seedling market. In 2019, the number of Dingfeng family lines has reached more than 100, and it is still expanding. The rich family lines ensure the genetic diversity of Dingfeng shrimp and are more adaptable. With this advantage, the group can also be more diversified in its product positioning of shrimp cultivation.
To ensure the independence of breeding, the personnel of Siamese shrimps in Thailand are independently composed, but the technical level follows the fine tradition of Dingfeng, such as choosing a farm close to high-quality sea areas to develop; a closed shrimp farming environment to ensure biosafety; strictly limit the production quantity of shrimps to ensure the quality of shrimps, protect the market and the price of shrimp fry; strict screening to ensure the quality of shrimps; high maturity, it can be used for production immediately without long-term temporary cultivation; continuous breeding tests to ensure the stability of the traits; conduct EHP, WSSV, EMS, IHHNV, IMNV, ATM and other shrimp specific pathogens at Centex Shrimp (Laboratory of Shrimp Molecular Biology and Biotechnology, Mahilong University, Thailand), to ensure 100% disease-free in real time, and pass the inspection of the Ministry of Fisheries of Thailand during export and obtain the test results. Thai Siamese shrimps are also shipped in Thailand, with short transportation time, which greatly ensures the safety of shrimps.
Site selection of sea areas with excellent water quality

China's shrimp breeding areas are wide, with many models, and the levels of farmers are uneven. In addition, environmental deterioration, the breeding success rate is extremely unstable. Among them, the breeding outside the pond is still the main model, which is greatly affected by the weather and diseases, and has high requirements for growth rate and disease resistance. The emergence of "balanced" shrimp - Dingfeng tolerant resistance, undoubtedly provides a brand new choice, which is worth looking forward to!
