Introduction of bait and management techniques for quail species in trout farming

The squid, also known as white peony and white bream, is a valuable fish in freshwater farming and has a high economic value. The squid's meat is very delicate, delicious, rich in fat and protein, and has a very high nutritional value. Basically artificial breeding. Carp is China's largest export aquatic product, bringing 6--8 dollars of foreign exchange income to the country every year. The world's main consumer of carp is in Japan, and 90% of China's carp products are sold to Japan. Due to the good economic benefits of squid farming, the development of eel farming in China has developed rapidly in recent years. In squid farming, the breeding of scorpion species is a very important part. Here we introduce the feeding and management techniques of scorpion species in professional squid farming.

Every kind of breeding pond is equipped with a food court. According to the characteristics of the living characteristics of the catfish, it is better to have shade buildings in the food field. Each pond is provided with 2 to 3 food platforms (bait boxes). The mesh size of the food table is gradually changed depending on the size of the species. The fish can both enter the table and eat as much as possible, and the small piece of bait is not easy to leak out. : In general, a table with a size of 0.4 cm is used for the ones with a specification of 0.5 g or less; a mesh size of 1 cm is used for 1 to 3 g; a size of 1.5 to 10 g; a size of 10 cm or more; cm. For each feeding, the bait frame should be hung close to the water so that the loss of feed is less.

It is necessary to open the aerator during feeding, so that with the flow of water, the smell of the bait quickly spreads to the whole pool, attracting the squid to feed on the food market. At the same time, fresh water is constantly flowing into the food market to flush out the manure and bait deposited at the bottom of the food field to keep the food field clean and improve the water quality conditions of the food field. This will help the carp eat at a high density in the food field and prevent the carp from being absent. Oxygen causes vomiting.

1. Breeding times

The squid who had just been raised to the secondary pool were baited three times a day (2 times in the morning and 1 in the afternoon). When the squid grew to more than 0.5 grams, they could be fed twice a day for 7 to 8 hours in the morning and 1 in the afternoon. ~ 2 hours. In the summer afternoon, when the water temperature rises above 33°C, the feeding capacity of the carp is poor. Therefore, the feeding time should be advanced to 5-6 am and 10-11 o'clock in the morning, and no baiting or feeding in the morning should be done in the afternoon, and it should be postponed to 6 o'clock in the afternoon. . This time it must change with the specific climate and water quality conditions.

2. Feeding amount of quail species

The amount of feed varies greatly depending on the temperature, water quality, weather and other specifications. Generally, under the conditions of good temperature, water quality, and good weather, the daily feeding rate of 1 gram of quail (the percentage of dry weight of the bait is 8% to 10%), and 3 to 5 grams of 6% to 8%. 5 to 10 grams of 5% to 6%, 10 to 20 grams of 4% to 5%. When the pod grows to more than 20 grams, it can be in accordance with the breeding method and feeding ratio. As for the determination of the specific amount of feed, according to the feeding situation of squid, it is generally grasped each time the training of the bait, in 1 to 1.5 hours after eating the right amount.

There are plans in advance for the feeding of quail species. The amount of feeding mainly refers to the following three aspects. The first is the amount and size of the oysters (which can be calculated from the weight and the number of tails at the time of stocking, plus the expected feed efficiency from the feeding amount since stocking); the second is the last two days of eating. Third, the day's weather, water quality, and gathering activities in the food market. After the number of feedings is determined, when preparing the bait, one or two ponds with better feeding should be set aside for feeding. Observe the feeding conditions of the feeding pools of the feeding ponds before deciding on the amount of the last batch of bait. Prevent the waste of feed due to abrupt changes in climate and the reduction of food by carp.
