The amount of fish consumed per day depends on many factors.
Daily food intake is different in individual species. In the same species, this diet varies depending on the age of the fish, the quality of the feed, the season of the year, the condition of the fish, and the concentration of the feeding fish.
Usually young fish consume relatively more food than old ones. The daily feed intake by fish larvae is equal to their mass, i.e. 100%.
The amount of feed consumed per day depends on the quality of the feed itself. The various amounts of feed eaten are directly related to its calorie content and sometimes digestibility.
The intensity of feed consumption depends on the condition of the fish. During spawning, many fish stop feeding. More well-fed eat less food than poorly fed.
Daily food intake also depends on the concentration of feeding fish. At the same time, juveniles feed at higher concentrations more intensively than at low concentrations. In adult fish, on the contrary, with significant concentrations, the intensity of feeding decreases.
It is known that the fish grows all life, only at different speeds. In accordance with this she eats. Need to know the approximate need of fish in the feed.
Here are the data on its daily consumption (with optimal content):
- from the moment of transition to active nutrition up to two weeks of age. 150–170% of fish weight;
- from two weeks to one month. 80–100%;
- from one to two months. 30%;
- from two months to the moment of separation by sex. 15%;
- from the moment of separation by the floor to full maturity. 5-10%;
- manufacturers. 3-5%.
In the prespawning period, the mass of feed is increased by 1-2%; during spawning, as a rule, producers are not fed; after spawning the fish, they are kept on a diet for two days, reducing the usual amount of food by 1-2%.
Feeding mode Most adult fish are fed at intervals of 8 hours (except for night time); food debris is removed half an hour after feeding; young juveniles after 6 hours, cleaning after half an hour; fry at the age of 1-2 months. 4 times a day, cleaning. in an hour; fry up to one month. once every 3-4 hours (at night it is necessary to turn on low light and preferably feed), cleaning after 2 hours. Fryers up to two months of age should be twice a day (go after each feeding) as much as possible and replace up to a third of the volume of water with fresh water of the same chemical composition and temperature, or move them to another container with settled water.
It should always be remembered that live and fresh food (less frozen) is more complete and physiological than substitutes. feed, feed mixtures, etc.
Adult fish and young fry, determined by gender, need to arrange a fasting day (not to give food at all) every ten days, replacing part of the water in the aquarium.
Introduce new food components or change the “menu”. You need to gradually. every day up to 10-15% of the diet. New, MI previously known feed can not be used immediately. First you need to test them on a group of experimental fish in a separate container. The best advisers in the selection of feed. the fish themselves (or rather, their reaction to a particular food).
The size of the food objects should correspond to the size of the mouth of the fish. Feeding can begin one hour after the Light is turned on in the aquarium and finish one hour before the shutdown (the time it takes to clean up food residues and fish excrement).
What is the best way to feed aquarium fish?
When buying fish, you first need to think about whether you can provide them with good nutrition. There are enough omnivores that eat both live and dry food; others are difficult to teach to dry food, they have to give only alive.
Of the most common natural foods, the best are the bloodworm (mosquito larvae from the family Cyironomidae), cororet (mosquito larvae from the Culicidae family), daphnia (Crustacea), Cyclops (copepods), and the strawberry (ringed worms from the Tubificidae family).
In addition, fish can be fed gray-black larvae of devil mosquitoes (family Culicidae), earthworms, pottery worms — enchitreus, flies and their larvae, caterpillars (not hairy), cockroaches, crickets, aquatic and land mollusks.
