As the opposing side, we may start from two aspects: one is to emphasize that frogs are beneficial insects, and tadpoles will grow into frogs in the future. Frogs are beneficial insects of crops and good friends of human beings. Data show that an adult frog can eat more than a dozen rice lice or rice leafhoppers at a time, more than 50 a day, and tens of thousands of pests a year. If there are 100 frogs or 1000 frogs in an acre of rice field, it can eat 1000 to 1000 pests a year. We can know how much contribution frogs have made to mankind by protecting beneficial insects. Nowadays, farmers' friends have little knowledge of the protection of frog beneficial insects, and always think it is delicious on the table. It is particularly common for many rural farmers to catch frogs at night, which is a concrete manifestation that pests also harm themselves, destroy ecology and destroy production. We must act quickly to protect beneficial insects and frogs, and never catch and destroy frogs.
Second, raising tadpoles will only affect its growth, and even affect its predation on pests in the future. Just like the tiger, the king of the forest, the tiger is the king of all animals in the wild. Once kept in a cage, its wildness will be gradually erased, losing its nature and its ability to hunt in the wild. Such a vicious circle, the tiger's nature will disappear, we feed tadpoles in the same way, change their living habits, and eventually lead to the destruction of ecological balance.
As a positive, we can also start from two aspects:
First, the process of raising tadpoles. Raising tadpoles is really simple! Moreover, many interesting phenomena can be observed in this process. However, there are still some things to pay attention to, which can help you raise it easily!
In fact, raising tadpoles is like raising a pot-bellied fish. The jar should not be too big, preferably not more than one foot (30? ); Even if it's a container that won't leak! The biggest difference between keeping small fish and tadpoles is that the former can be kept for a long time, while the latter usually becomes a small frog in 1 ~ 2 months. Therefore, you don't need to spend too much "gorgeous" equipment and furnishings; Unless, you raise frog tadpoles (tadpoles for more than half a year), or you raise small fish aquatic plants by the way. Otherwise, the "luxury house" that has been painstakingly renovated will soon be revoked!
Therefore, raising tadpoles only needs a "bare jar" (that is, empty basin water); If you think this is too cruel, just lay a layer of fine sand on the bottom and put some strong aquatic plants, which is very advanced. In addition, when collecting tadpoles, you can observe the original living environment of tadpoles a little. If it is caught in a still pool, it can be raised according to the above method. If tadpoles are caught in flowing water, it shows that the tadpoles have a high demand for dissolved oxygen, so an air pump should be prepared for them to minimize the gas output and avoid excessive water flow. Prepare another basin for changing water. The most important thing to pay attention to when raising tadpoles is the water quality. There are many factors that affect the water quality, including the number of tadpoles, the type and quantity of feed, the frequency of feeding and the layout environment. The most direct way to maintain good water quality is to "change water frequently", but how often is it changed? Changing water too often is also very troublesome, just change it every 3-5 days! When changing water, you only need to pour 2/3 of the water, and then add the aerated tap water to the original position. It is suggested to prepare another container for water aeration, and then fill it with water after each water change for the next water change. But the worst water quality is usually at the bottom, where there will be a lot of feces and inexhaustible feed. Therefore, when changing water, it is best to suck up the sediment at the bottom as much as possible to effectively improve the water quality.
Therefore, under such a frequency of changing water, the number of feeding times is determined. Although tadpoles can't be eaten as much as possible, they can't be given too much at a time, which wastes food and easily pollutes water quality. Therefore, according to the feeding times, different amounts of feed are put in; With a little observation, you can eat almost 2-3 times a day every time 10 minute, or add it slowly until the tadpoles stop eating. If you raise it at your desk, you can also adopt the method of "small meals and more meals", but only if the boss does not object to raising it first.
As for the number of tadpoles (it should be said that the density of tadpoles), it is best not to be too much. In this way, feces will increase and water quality will soon deteriorate. Secondly, living too close can easily lead to diseases and poor health. If you keep some big tadpoles, you should keep them sparsely and leave room for them to grow. Of course, you can only raise a few, and you don't have to change the water too often!
Common fish feed
Of course, if a frog wants to grow well, it must be provided with proper nutrition, that is, it must be fed. The simplest way is to use "fish feed", which is easy to buy and easy to feed. However, there are many kinds of fish feed on the market, each with its own characteristics. Which one should we choose? There are several principles to choose from:
"Quantity", as I said before, tadpoles will end in about two months, and it will be wasted if you buy too much at a time. If you have fish, you can use the same feed.
"Characteristics", after the feed is put into the water, some will float and some will sink. Observe in advance which water layer your tadpoles like to feed on (surface layer, middle layer or bottom layer), and then buy feeds with different characteristics.
"Ingredients", it is not easy to judge the quality of feed directly by the label of ingredients, but you can choose feed suitable for general fish with balanced nutrition.
"size", feed that is too big can't be eaten immediately, and it can only be eaten after soaking thoroughly (otherwise it needs to be slightly ground); If the feed is too small, the feeding efficiency of tadpoles will be greatly reduced. Of course, it needs a little observation, and then they can choose the right feed.
If you suddenly run out of feed, or occasionally want to change your taste, you can choose "rotten vegetables" (boil them, don't put them in! ), making tadpoles easy to scrape. If you find it troublesome to cook every time, you can cook a little more at a time, then soften it into green vegetable balls of moderate size, freeze them, and take them out one at a time and put them in water. After a while, tadpoles can eat. In this way, tadpoles can grow smoothly through interaction with feed!
Secondly, feeding tadpoles has played a role in protecting tadpoles to a certain extent, avoiding tadpoles from being killed in the stomach of fish or being captured and disabled by some ignorant farmers. Do you think tadpoles really find their mother as smoothly as they write in the book? How many dangers and hardships have to be experienced along the way.
Thirdly, feeding tadpoles can also exercise our independence and cultivate our love and perseverance. Therefore, we will know more about frogs, their growth process, their benefits and thank them for their contributions. May I ask the opponent, you keep saying that frogs are beneficial insects and want to protect frogs, but what have you done to protect frogs besides paying lip service? We know that frogs are beneficial insects, and we are doing our best to protect their tadpoles. Are we wrong? You're just talking, you're right, we're just putting anti-party slogans into action, but we're wrong? If the opponents say that it is wrong for us to protect the tadpoles of young frogs, do they mean that frogs, as beneficial insects, should not be protected by us? The opposing side's statement is so contradictory, how can your theory be convincing?
Because raising tadpoles as a positive side is not easy to demonstrate, when grasping each other's weaknesses, we must hold on to it, affirm that frogs are beneficial insects, and say that raising tadpoles is to protect frogs' babies, then the argument against it will naturally be broken!
