How to determine the age of fish?
It is important to know that there are simple ways by which you can determine the age of fish. For this you will need fish and attentiveness. This is a useful skill with which it is possible to determine the age of fish, which will definitely be able to surprise your friends and acquaintances, even not being an expert or an experienced angler.
There are several options which can determine the age of fish.
Determine the age of fish
Weight and size — this is the first method by which to determine the age of fish. It all depends on the environment, it may be a fish fed feed in the pond. Depending on the environmental conditions it can grow and develop unevenly.
But there is another way of determining the age of fish, which is popular among fishermen, and is considered more accurate than the previous one. This method equates to calculating the age of trees by their annual rings. But in fish, is to learn the scales by looking at the gills, or in her bones, for it is only need very carefully to consider them. This can be done much easier than it would seem. Taking the fish, you can see it on the scale ring. The principle on which it is possible to determine, based on the formation of layers in the form of rings on the fish scales, which alternate with each other. Each ring is responsible for passing year. Moreover, with the help of this method, it is possible to determine not only its age, but the size which it has grown over the past year, in other words, the annual ring. Because we all know that fish growth in length, grows and increases in size its scale. It’s more than actually make the sclerites. The sclerites are troughs and ridges that are formed on the scales. They are visible to the naked eye. In one year, up to two layers of sclerites is one more, another less. Due to the large scleritis can be traced to the active growth of fish and less you can learn how have weathered the winter. When the fish is rapidly growing, therefore more increases of the sclerites, and the distance between them becomes wider. The slow growth of distance between sclerites reduced, they become closer to each other. However, in order to determine the age of fish, you need skills and a little knowledge in this area. After all, the scales of big fish, make it easier than the small scale of representatives. For studies which may need special equipment. If absolutely can’t wait to find out the age, we recommend that you take the fish skeleton.
How to determine the age of fish by the rings?
Please note that the rings are arranged in several layers. Those that are wider, they are light, which is already darker. Wide are responsible for the active growth and rapid development of the fish. Usually, it is a warm time of the year when fish favorable conditions for life: spring, summer or early fall. Dark — formed, if the fish lives in cold, icy water, and little eats. If there were difficult conditions in winter, it becomes difficult to identify the dark ring. Rings of scales can determine the age of fish and its length, on which it has grown over the past year. Fish having a length up to 1 m, have scales of up to 1 cm From the rings to the centre of a single scale distance is about 3 mm. on this Basis, we conclude that over the past year, the fish grows to 30 cm it Should also be noted that some representatives of the fish is missing scales. It can be naked carp, catfish, tench. But do not despair, their age can be identified by their tubular or flat bones.
