Australian shellfish fish cage culture benefits

In recent years, most farmers have cultivated bamboo shellfish in ponds, but there are fewer ways to use cage culture. Although some people know that there is a method for breeding cages in Thailand, they are used for cage culture in mainland China. Actual. According to the life characteristics of Australian shell fish, the range of activities is small, so it is suitable for breeding in the environment of small water bodies. There are many advantages in cage breeding in ponds or reservoirs:

1, easy to maintain. With cage culture, it is easy to observe and check the fish condition. The daily activities of the fish are obvious at a glance. If there is a problem, it is very convenient to handle it. When the breeding process needs to be repeated and grading by multiple sizes, the operation of the fish distribution is also simple.

2, using cage culture Australian shell fish, good growth, fish neat, fast speed. Due to the small scope of the cage, the fish is relatively concentrated. When the feed is fed, all the fish are able to catch food. Since the fish concentrate on eating, the food is particularly full, which can prompt the fish to have a faster long speed.

3, the water utilization rate is high. There are many farmers who use ponds for breeding, but also want to breed some other varieties. Because the life characteristics of Australian bamboo shell fish are docile and do not love to swim around. Once mixed with other fish, it will affect the feeding and long speed, such as hanging cages on both sides of ponds and bridges. In this way, the ponds can be stocked with some suitable species. This can achieve a good effect of cage culture and the same high harvest rate. The double benefit.

4, stocking density. The seedlings that are required to enter the cages are preferably 8-10 centimeters or more in length. Generally, about 100 tails per square meter of water can be stocked. Until the raising of the market specifications of about 500 grams can maintain this density, but the water quality must be kept fresh.

Australian shellfish fish cage culture conditions

1. The use of cages for aquaculture requires larger ponds, better water depth, and better breeding of cages in reservoirs because the water quality is relatively stable.

2. The size of the cage is usually 4 meters long and 3 meters wide. The cage dives to a depth of about 2 meters. The mesh size depends on the size of the fish cultured in the cage. The quality of the cable and reticulation is better and smoother. The net cloth is better.

3, hanging net requirements: the bottom of the cage should be about 30 cm away from the bottom of the pond to ensure that the bottom of the net is not polluted. The four corners of the cage are best made into garden corners. Before the seedlings of the cages are placed, some water lettuces should be stocked in advance. The area covered by the water lettuces is about 3/5 of the cage area, leaving 2/5 of the space for the convenience of bait feed. However, it is advisable to hang a tight net bag under the feeding position. After one hour of feeding, check the bag to check if there is leftover material, so as not to sink the leftover material into the bottom of the cage, causing waste and pollution.

4. The feed of Australian shellfish is mainly used for soft bait such as chilled fish or squid. When the fish grows to a large size, the chilled fish can be fed with the cut fish, and the feeding method is an artificial renewal box. After the fish have finished eating and then feed continuously, the feeding time must be regular, and the feeding amount is based on the food supply.

The cage culture should pay attention to several points

1. Please note that the cages are kept intact and cannot be broken so as not to cause fishing, especially ponds that have raised blue crabs and raised turtles. They also need to prevent turtles and blue crabs from crawling the cages. Once they are found, they can use fish threads. The sticky net is placed around 2 meters away from the cage, so that once the soft-shelled turtle or blue crab wants to enter the cage, the sticky net can catch the turtle or blue crab.

2, cages in the water for a long time, the president grows moss, which leads to poor dredge, this can often use potassium permanganate water diversion in the cage range spilled for 20 minutes, this can not only remove the cage moss but also Can play a role in disinfection.

3, to be often grading: In the breeding process, the fish will appear in size, in order to avoid the impact between size, according to the fish to be separated in time, in the classification of network clearance to check whether there are holes in the cage. Once there is a hole, it is necessary to make up or replace the cage in time. In winter, hang cages and don't forget the fish's temperature requirements.

4. Build confidence through trial training. Australian cage fish cage culture is a very good way of breeding, I have adopted a variety of farming methods, methods, after several batches of fish of different specifications for farming to sum up the above practical experience for reference for farming. If you don't have enough confidence, you can use a cage to try it out, and then you will breed it with 10, 30, or more cages. In this way, you will likely become a web-based atmospheric school breeder.
