What fish eat in nature | What aquarium fish eat

Food food, like any living creatures on Earth, ensures the course of all energy (and others!) processes in their body.

Like many other residents of the planet, fish at the first stages of their life existing provide it at the expense of the resources that were transferred from the mother’s body we are talking about the yolk of caviar.

But due to such an image of food, fish cannot exist for a long time only a limited period of time. And after the interval of mixed nutrition, they usually completely switch to the appearance of the feed.

A variety of nutritional methods

There are a huge number of species of a wide variety of fish and all of them also differ in the nature of the food consumed: here the value of the object of consumption and systematic affiliation matters here. It is not surprising that it is fish that are record holders among other types of animals in terms of a variety of food consumed.

In the image of fish, fish are divided into several types:

  • Herbivorous that consume a variety of aquatic plants.
  • Livestock, feeding invertebrates.
  • Predatory, in whose diet, fish and other vertebrates consist of.
  • Predatory fish are usually divided into:

  • Ambush are those species that usually sit in ambush, t.e. they lie for days and simply wait for food (catfish, pike);
  • active predators they do not stand still, pursuing prey until they grab (salmon, perch).
  • In fact, such a separation is quite conditional so, animal can sometimes consume young animals (sometimes even their own). At the first stages of food, any young animals in the early stages can serve the smallest protozoa, and only then the transition to large nutrition objects plankton, claws and other crustaceans is carried out. And only then there is a division into herbivorous, livestock and predatory, and the nature of the nutrition can change over time.

    Most fish species are able to eat both plant food and a variety of animal organisms. Those who prefer exclusively herbivores are not so much (sweatshirt, white Amur).

    Method of nutrition

    Fish eat in a wide variety of ways. Some of them consume food from the surface of the water, most prefers to find it in the middle layers, but a certain number of species collect it from the bottom, rummaging in the ground. Predatory fish also use various techniques.

    According to the method of feeding, fish acquire their body forms, as well as in the process of evolution, they have formed a special device of the nutrition organs, which helps to eat specific food:

  • Those species that feed on the surface are distinguished by an elongated body and usually a straight back. Their mouth is located up, which provides the possibility of maneuvers and hunting for insects.
  • Pisces that are looking for food at the bottom of the reservoir, on the contrary, formed a straight belly that does not complicate the movement along the ground, and the mouth facing the downpart with a mustache that help to detect food.
  • Fish with a plant diet (algae, for example) have wide lower lips, which practically performs the function of a plate scraper that cleans the algae cover.
  • Food of fish

    The indicator of the need for food has a significant impact on the behavior of any type of fish: they often have an intraspecific (what to say about interspecific!) the struggle for food objects.

    Moreover, under natural conditions, with a sufficient amount of food and its diversity, the frequency of eating is not at all the same for different fish. For example, the amount of food consumed in fish of one species may change here the age of individual plays a role, the quality of food, and even the season of the year.

    Conditionally food, if we take into account the attitude to it of fish, can be divided into several categories:

  • Favorite;
  • replacing;
  • Forced.
  • For example, under normal conditions, the fish, of course, will choose a favorite food for saturation. But in the event of a lack of (or complete absence) of food, the fish will perfectly switch to a replacing nutrition. Well, if it is not enough then the need to consume forced food will be used.

    Most of the fish feed for a daylight, but some species eat at night; Predators, having saturated with prey, may not resume hunting for a long time hours or days.

    In all fish, the main share of the adopted feed (and the one that is absorbed) goes to support all the functions of the body: metabolism, movement or breathing. A similar feed was called the supporting person and the more it is the more significant than the size of the fish itself. There is another type of feed producing, t.e. the one that goes to increase the size of the body. At an older age, like all organisms, in fish the growth rate decreases and, accordingly, the volume of the consumed feed will be reduced, which goes just on maintaining life functions, and not for a set of mass.

    Feed of aquarium fish

    Of course, those fish that are contained in the aquarium are forced to adapt to the power regime that is established by the rules developed on practical experience. In this case, a twotime power option is considered normal practice in the morning and at night. It all depends on the types of fish for example, you need to understand that feeding fish is only unacceptable once a day. Although there is an opinion among aquarists that it is better not to fade fish than to overfeed-for their normal state. But in general, fish requires quality food and they should always be wellfed.

    The number of food required for a day differs depending on the species variety of fish. Here, as a rule, the quality of food, water temperature and oxygen content, and the physiological state of the body are important. It is clear that the wellfed fish does not eat as actively as hungry and exhausted, but young animals are characterized by an increased diet compared to adults.

    There are a lot of feed for aquarium fish:

  • animal origin;
  • dry food;
  • frozen food;
  • plant food;
  • Artificial mixtures.
