Reservoir for help, too many little tilapia. What to do if there are too many small tilapia fishing

Tilapia has basically no natural predators in the fish ponds of the freshwater reservoir in Fujian Province, Guangdong, and the alien species have been invaded, and there is no way to extinct it in the short term. There are several ways to reduce the number of tilapia, option 1: increase the fishing of birds, such as ducks and egrets, which will prey on small tilapia, so as to reduce the number of small tilapia.

The advantages of this approach are: the presence of birds increases the ecological balance; The disadvantage is that these birds or ducks do not prey only on small tilapia, which has many spines and a strong taste, and it is not the bird that preys on fish, it will prey on other native fish with fewer spines and tasty tastes.

Method 2: stocking crabs, crabs' eating habits are very mixed, the same as tilapia, if there are crabs in the reservoir fish pond, he will compete with small tilapia for food, the amount of small tilapia food can naturally be reduced, in addition to the crab itself will prey on small fish and shrimp, the swimming speed of small tilapia is not as fast as the native fish, it is a good predation object, there are crabs preying on small tilapia, the number of small tilapia will be further reduced. Tilapia has the same egg-protecting phenomenon as crabs, tilapia will put eggs in the mouth until hatching, crabs will also put eggs in the crab tail until hatching, and will not be eaten as food by small tilapia after laying eggs, ensuring its reproduction.

Other fish will lay their eggs on the grass, as long as the fish spawn will be eaten by tilapia as food, which is the fundamental reason why the local people can't compete with tilapia, because there are no offspring, the food is also robbed by tilapia, and it will naturally become extinct. It is also important to note that crabs are native species, have good economic value, and do not threaten the survival of other native species, and it is not advisable to introduce other exotic predatory fish to the extinction of native species.

Do you fish with sweet corn View the original post "Satisfied".

Use a larger net to fish. When fishing for fish, the density of the net should be considered, and the pores of the net should be slightly larger, so that the smaller fish can leak out the small fish, and the rest is the big fish in the later stage, which is relatively convenient.

Learn about tilapia preferences and choose fish food. Tilapia likes fishy food, at this time we try to choose lighter when we prepare, some grains may be eaten less, but the large type with tilapia is more experienced and will not be easily fooled, at this time we also need to laugh and need to consider, for the large tilapia summer food as much as possible to choose frozen.

When fishing, you should pay more attention to the changes in the fish drift. When fishing, we need to look at the fish float, generally the fish will sink when the fish is hooked, and the fish will float up after not catching the fish, if the small tilapia eats, we will find that the fish drifts strongly and the direction is not fixed.

A grandson rents a place and wants to change places after staying for a long time. When fishing, there will be a lot of small tilapia to grab food, we stay in one position for a long time, it will only make more and more small fish gather, then we have to find the right time, like moving some around, in order to stay away from the small fish, so that some big fish take the bait.

If you catch too many small fish, try to put them back. Too much small fish fishing is easy to make a certain fish in the reservoir will be extinct, we try to put the small fish back when fishing, let it grow up and then fish, the general fish in the breeding period should also limit the anglers, so that the fish have a good breeding life circle, but also make the small fish can grow well.
