To purchase crab seedlings, farmers should establish quality awareness

Entering the “Thirteenth Five-Year Plan”, the development of fishery from the past “increased production and income” to the “improved quality and efficiency” stage, the quality of high-quality aquatic products to better prices, prices will increase efficiency. The goal is: By the end of the “Thirteenth Five-Year Plan”, the quality, efficiency, and competitiveness of fishery development will be significantly enhanced, fishermen’s lives will reach an overall well-to-do level, and coastal areas, the middle and lower reaches of the Yangtze River, and the Pearl River Delta region will be the first to basically achieve fishery modernization.

At present, the main monitoring items for quality and safety monitoring of aquatic products are malachite green, chloramphenicol, nitrofuran metabolites, Escherichia coli, total bacterial count, lead, cadmium, diarrhetic shellfish toxin (DSP), and paralysis. Shellfish poison (PSP), PCBs, etc. The cultivation of crabs should be promoted in healthy breeding, and the use of “banned drugs” is strictly prohibited.

There are large differences in climate between the north and the south of China, and some farmers in the current climate-friendly regions have begun to launch crab seedlings. When purchasing crab seedlings, we must first establish a sense of “quality and safety”, followed by the price of crab seedlings.

View Tangkou Record Consultation Grassroots Fisheries Agency

Crab farms need to produce licenses, with detailed records of the Tangkou. Purchasers can learn about the development of crab seedlings by looking at the relevant records, and they can also consult the grass-roots fishery organizations in the location of the crabmeat farm, so that they can purchase the good quality seedlings with confidence. Grass-roots fishery agencies will effectively supervise the seed farms within their jurisdiction. For example, the Agriculture Bureau of Gaochun District, Nanjing City, Jiangsu Province recently organized fishery supervision brigades and the Department of Fisheries, and conducted aquatic seedlings for the whole area's crab farms (households). Law enforcement inspection. Site inspection of crab seedlings: specifications seedlings per catty 60 to 80, specifications neat, shiny body, appendages intact, visible food in the intestine, strong ability to move, no disease occurred.

High-quality crab seedlings are the basis for breeding large-scale crabs. A good crab can be identified by the following points:

1. Crab seedlings are neat in size. Neatness means that the weight of each crab is basically the same. This determines the synchronization of clam shells in crab farming. Simultaneous clam shelling can effectively reduce the killing of crabs, and it also facilitates crab management.

2. The appearance of the crab shell is bright and bright, with complete appendages and no body surface parasites.

3. Crab claw sound, golden, no wear. If the tip of the crab claw is worn out, it may be a seedling with a long storage time.

4. The length and width of the crab leg should be evenly proportioned, and the third appendage exceeds the eye point when “receding the leg”. This kind of crab has an advantage in growth.

5. Uncover the shell of crab seedlings. This kind of crab has good constitution and it is easier for the first time. If the abdomen is bright and transparent without meat, the mortality of crabs is high when they are shelled. Then observe the crab, white, light white is better, can not have black, serrated situation.

The number of seedlings purchased is determined by the seedling release plan. What kind of farming mode should be adopted, and how many seedlings should be put on it, which should be planned before purchasing seedlings. According to the situation of crab breeding and price changes in 2016, some experts suggested that the density of seedlings should not be high, and small ponds (below 50 mu) should be kept in the range of 1000 to 1200 per mu, and more than 50 mu should be planted in Tongkou. Only within / mu is appropriate. This stocking density is based on the refined degree of Tangkou management and the return on investment in Tangkou. For a higher degree of fine-grained management of the “small fine high” Tangkou, it is also possible to formulate a stocking plan based on their actual situation.

Before the seedlings are released, they must first test water and bubbling seedlings. When testing the water, 10 shrimps with better quality can be selected. The shrimp seedlings are hung on the bottom of the pond in a mesh bag. After 48 hours, the vigor of the shrimps is checked to determine whether the water quality meets the criteria for releasing seedlings. If the shrimp show normal signs of no poisoning, they can be planted.

Before the crabs are launched into the water, they must use the pond water to carry out the “bubble seedlings” and allow them to spit out the “foreign water” and draw water from the pond to improve their adaptability.
