How to raise a crab in a fingerling pond

In mid-April, the fish and crab farming area was thoroughly cleaned using 75 kilograms of lime per acre to ensure a clean and healthy environment. On May 15, a total of 200,000 carp, including grass carp, were released into the ponds. Four thousand kilograms of fingerlings, with each weighing about one kilogram, were introduced on May 20. Additionally, 2,000 bean crabs were added to the system. One month later, soybean milk was used as feed for the fish flower ponds, given once daily. After another month, when the fish reached a length of 3 to 4 centimeters, the feeding of concentrated feed was stopped, and instead, calabash (also known as flounder or sesame moth) was introduced as a new food source. After a week of this transition, the fish began to grow well. The waste produced by the grass carp and squid species served as natural fertilizer, enriching the water and also being consumed by other fish species like carp. From mid-June to late September, a total of 7,500 kilograms of calamus was fed into the pond to support growth. During July to September, the water transparency was carefully maintained at 10–15 cm to ensure the water remained clear, fresh, and suitable for optimal fish and crab development. After 10 months, fresh chicken manure was added as a supplementary feed, ensuring that the fish and crabs received adequate nutrition. By October, the water transparency was adjusted to 5–10 cm to maintain a stable and healthy aquatic environment. Water quality management is essential in this system. Feeding chicken manure can make the water too acidic, so quicklime must be used regularly to balance the pH. Typically, for an acre of pond with a depth of one meter, 15 kilograms of slaked lime is scattered every 20 days to maintain ideal conditions. Harvesting occurs around mid-October. Capturing adult crabs at the right time is crucial—harvesting too early results in underdeveloped crabs with low yield, while harvesting too late increases the risk of them escaping onto land. It is best done one week after the crabs reach gonadal maturity and before they begin to move ashore. The method involves using flashlights at night to spot crabs along the water’s edge, capturing them every hour for a full week. This process ensures most of the crabs are collected effectively. The benefits of integrating fish and crabs in the same pond are significant. They create a symbiotic relationship, enhancing productivity and reducing the need for artificial inputs. The natural ecosystem supports both species, providing ample food sources for the crabs. This method often outperforms single-species stocking. Moreover, in the fingerling stage, disease incidence is lower, allowing for reduced or even no use of antibiotics. As a result, the crabs are free from drug residues, making them more appealing to consumers.

Coffee Green Hydrochloric Acid

green coffee extract:

Green coffee bean extract is made from the green beans of the coffea Arabica plant.

There are two types of coffee plants, arabica and robusta. The arabica is higher in quality and higher in chlorogenic and caffeic acids, two primary compounds responsible for anti-oxidant activity. Coffee might have anti-cancer properties, and researchers found that coffee drinkers were 50% less likely to get liver cancer than nondrinkers.

Product features:

1. Special large package for industrial raw material sales(10kg/20kg);

2. 100% pure coffee;

3. Good instant solubility;

4. Stable raw material origin and long-term supply

Functions:

Losing weight.
Anti-virus; Anti-bacteria; Anti-cancer; Anti-aging; Anti-infectious.
Lowering toxicity.
Lowering blood pressure.
Reducing the risk of diabetes.
Help with muscle fatigue for athletes and bodybuilders.
Green coffee bean has strong anti-oxidant properties similar to other natural anti-oxidants like green tea and grape seed extract. Green Coffee Beans have polyphenols which act to help reduce free oxygen radicals in the body. Green coffee bean extract is sometimes standardized to more than 50% Chlorogenic Acid. Chlorogenic Acid is the compound present in coffee which has been long known as for its beneficial properties. This active ingredient makes green coffee bean an excellent agent to absorb free oxygen radicals; As well as helping to avert hydroxyl radicals, both which contribute to degradation of cells in the body.
