Crayfish farming is also a type of aquaculture that has only become popular in recent years. Crayfish is the only alien species that has been eaten alive and cannot satisfy people's appetite even with artificial farming. So when farming crayfish, does frequently setting nets to catch crayfish in the lobster pond have any impact on the shrimp in the pond? Is it good to frequently cast nets in lobster ponds?Actually, it depends on when you set the nets (cages) and when you take them out. Normally, you will go out to catch shrimp only when most of the shrimp in the pond have reached the market size. In this case, as long as we choose the right time, it will not have a bad impact on the shrimp. For example, in hot weather, try to set the nets in the evening and collect the cages before the sun comes out, so that the impact on the shrimp will be reduced. It is best not to set the nets and catch lobsters at noon in hot season or in hot weather. These two weather conditions are very harmful to shrimp. Improper handling will cause a large number of shrimp to die. As mentioned before, nets are only put out to catch shrimps when they are to be sold, which means that each time the shrimps are caught, some shrimps that can be put on the market will be sold. In this way, the density of shrimps in the pond will decrease. From the perspective of the entire breeding process, the density will decrease after a part of them are sold, which is more conducive to the growth of the small shrimps in the pond. If we look at it from this point of view alone, it is beneficial to the entire breeding process, which is not only conducive to increasing production but also to capital circulation. Of course, during the entire production process, you cannot set out nets to collect lobsters every day as soon as the lobster season arrives. This is not conducive to the growth and health of the shrimp, and too frequent operations can easily hurt the shrimp. Therefore, the best way is to set out nets to catch lobsters in different water bodies in turn according to the growth of the shrimp. When is the best time to cast the lobster net?Crayfish are mostly active at night, so it is best to put them in the cage at noon and collect them in the morning. Crayfish netting is one of the necessary means of catching crayfish. Only when the shrimps are caught by the ground net can they be sold profitably and generate value. Crayfish can only grow rapidly by molting. By reducing the density, there is more living space, especially during the peak growth season. After the density is reduced by setting nets, the growth rate is significantly accelerated, which is conducive to generating good value. How to download the lobster net correctlyIt is not recommended to fish for three days and dry the nets for two days when fishing in lobster ponds. It is necessary to set enough nets at one time. This can not only seize the high prices in the market, but also concentrate the output and ship quickly, thus improving efficiency and promoting the healthy development of aquaculture. When large-sized lobsters are sick, it is recommended not to set nets. When lobster ponds are sick, it is recommended to set fewer nets or no nets. After scientific treatment, the nets can be set in a concentrated manner. Finally, if you want to achieve good breeding benefits, you need to have both production and specifications, and most importantly, you need to keep up with the price. Good benefits are sold, and farmers scientifically arrange their production according to their own conditions. |
