New technology of shrimp worms
Shrimp polyculture is a new technology that utilizes shrimp ponds to raise polycultures without affecting shrimp production. It can not only improve the utilization rate of ponds and the quality of commercial shrimp and alfalfa, but also greatly increase the economic benefits of pond culture. The farming techniques are introduced as follows and referenced where applicable.
First, the pond conditions shrimp ponds mixed pond area is best between 5-6 acres. This will not only be easy to manage but also catch. Pool depth 1.2-1.5 meters, water depth 0.8-1 meters. The slope of the pond is 1:3, and the pond foundation is firm. In order to prevent flooding and escape, Tong-based iron or cement tiles can be used to prevent escape. Anti-escaped walls are required to be buried 20 centimeters underground and 30 centimeters high. In the north of the pool, a few cement tiles are located at the south position as a feed station. Half of the water is placed halfway between the water and the water. The pond requires easy injection and drainage, and the aquaculture water source should meet the national fishery water standards.
Second, shrimp stocking
(I) Preparation before stocking
1. Disinfection of fresh ponds In addition to the new ponds, the old ponds must completely drain the pool water and clear more than 15 cm of mud, and then disinfect it with 100 kg of dry lime in each dry dry pond. Clear water is injected 80 centimeters after 3 days. When the water is injected, the 80 mesh sieve filter should be used to prevent the entry of harmful organisms into the shrimp pond.
2. In order to supply the sputum to feed the biological feed of the earthworm, fresh spores of 100-150 kilograms shall be placed on each acre before stocking for reproduction and growth.
(II) Stocking
1, stocking specifications and density of stocking density according to the year to raise the law, so the stocking species specifications should not be less than 250 grams, so that by the fall of the season can develop into 0-6 kilograms of high-quality goods listed. Stocking density is 150 per mu.
2. Stocking time and method of stocking time East China and Central China are generally from mid-May to early June, and southern China is in early May. The water temperature of the pond at the time of stocking is required to be above 25°C and the weather is fine. The species of stocking requires uniform specifications, and no disease or injury. Before stocking, the carcass can be soaked in 4% saline for 10 minutes.
(C) Shrimp species The stock of stocked shrimp is best produced locally by self-producing freshwater prawn. The specification of shrimp species requires 1-5 cm or more, and the stocking quantity is 60,000 mu per mu. Restocking time in early July, shrimp species can be deepened to 1 meter after pooling.
Third, the daily management of daily management mainly to shrimp.
1. Feeding shrimp is fed with commercial shrimp feed according to conventional feeding amount. After stocking, some fresh live fish such as small ragfish and pig liver can be put in stocking. After one month, they can gradually stop feeding. Afterwards, they use bait shrimp and breeding snails as baits.
2. Water quality management During the breeding period, lime is properly applied to maintain the pH of the pool water between 7-7.5. Appropriate exchange of new water, changing the amount of water is generally 1/5 of the original pool of water.
3. The daily patrol pond The patrol pond is mainly for observing the activities of shrimps and cockroaches in the pool, the conditions of the barriers in and out of the water inlet, and the changes in water quality. The patrol pond should make records and discover problems and deal with them in time.
Fourth, fishing and temporary shrimp farming can be based on market conditions and growth specifications to take the combination of catch and centralized fishing. The clams have to wait until the dry pool is caught at the end of the harvest. Due to the relatively concentrated catching of crickets, if they can not be sold off once, they can be raised temporarily, and 25 centimeters thick moist sand can be laid on the idle floor of the home or warehouse, and the pupa can be buried in the sand. Usually at room temperature about 15 °C, can save more than 30 days. During the period, it can be gradually listed and sold according to the market conditions at that time.

Dried Squids are a popular snack in many Asian countries, especially in Japan, Korea, and Thailand. They are made by cleaning and drying fresh squids until all the moisture is removed, resulting in a chewy and flavorful snack.
Pure dried squids are made without any additional flavorings or seasonings, so they have a natural taste that is slightly salty and briny. They are often served as a bar snack or as a topping for rice dishes, noodles, or salads.
Dried squids are a good source of protein and low in fat, making them a healthier snack option than many other processed snacks. They are also rich in vitamins and minerals, including vitamin B12, selenium, and phosphorus.
Overall, dried squids are a tasty and nutritious snack that can be enjoyed on their own or used as a flavorful ingredient in many dishes.
