Golden carp cage culture technology

1. Selection of sea area

The choice of sea areas for cage culture of golden mullet is very important. Golden mullet is a warm-water fish. The sea area is best to be selected in the sea area south of Huidong (including Huidong) of Guangdong. The bottom of the cage is about 1.5 meters away from the bottom with a minimum tide level. The wind and waves are calm and the traffic is convenient.

2. Stocking specifications and density

In the breeding stage, for early harvest, the fish seedlings with a body length of about 6 cm can be sold as early as 40 to 50 fish/cubic meters. If they are not in a hurry to harvest, the breeding density can be appropriately increased.

3. Daily management

(1) There are mainly two types of bait feed, one is fresh fish; the other is artificial feed. Due to the smaller mouth of the golden mullet, fresh fish must be fresh, crushed to prevent fish bones stuck in the throat and starved to death. In June-August, the daily feeding amount is more than 20% of the fish’s body weight and is fed two times a day. In other times, the amount of feeding can be appropriately reduced depending on the circumstances at other times. In order to accelerate the growth rate, the daily feeding amount can be increased by about 40% of the fish body weight, and the number of feedings can be increased to 3 times - 4 times or even 5 times. Formulated feeds can be fed by referring to instructions.

(2) Safety inspections In order to prevent fish from being caught, check the cages frequently. After the typhoon, check whether there is any loss in the cage and whether fish escape occurs.

(3) Elimination of cage attachments Net cages will enter the sea for a period of time. Defiled organisms will adhere to the cages and must be promptly removed.

(4) Accumulation of records and data is an important task in raising fish farming technology. Every day, we must make detailed records of water temperature, salinity, fish feeding conditions, dead fish conditions, weather changes, and fish diseases.

Food Sweeteners

Sweetener is a food additive that provides a sweet taste like that of sugar while containing significantly less food energy. Some sugar substitutes are natural and some are synthetic. It allows you to enjoy sweet tasting foods without the extra kilojoules from sugar. It can be beneficial for anyone trying to lose weight and control their sugar intake. Sweetener also does not contribute to tooth decay, as they are not broken down to acid by bacteria in dental plaque.
