First of all, the water quality should be kept clean and pollution-free, and dissolved oxygen should be sufficient. The culture area is about 0.5 to 5 mu, and the water depth is about 1.5 m. When feeding, fish of different sizes should be cultured separately to prevent each other from eating. At the same time, you can put some wild fry and shrimp in the pond and let them reproduce naturally. In order to provide bait for tiger fish, snails, maggots and mussels can be added in the late feeding period or when the feed is insufficient.
Gecko needs to live in rivers or ponds with pure water quality, and cannot grow normally in polluted waters, so this kind of fish is a very healthy and pollution-free green food. Now people pay attention to healthy diet, so this kind of fish is liked by many diners, which is why it is more and more expensive.
The following points should be done well in raising ground tigers: 1. Patrol the pond every morning and evening 1 time, and fully grasp the feeding, activities and growth of fish through patrolling the pond; Second, regularly detect the changes of water quality such as ph value, transparency, dissolved oxygen and water temperature; Third, regularly check the integrity of facilities such as aeration and escape prevention, and take corresponding measures in time when problems are found.
