Growing aquarium fish on organic food objects

Abstract

The dependence of the cultivation of predatory aquarium fish on the use of live food in the diet as an organic food object in the aquaterrarium of the Roev Ruchey Park in the city of Krasnoyarsk was studied. When choosing an organic food object for growing ornamental fish, guppies and swordtail fish of the Pecilia family were considered. Their diet consisted of a combination food and meat mix for freshwater fish. Swordtails gave offspring more than guppies by almost 2 times, puberty came 1 week earlier, the life cycle is longer by 2 years. Brilliant cichlazomas of the studied groups received a combined feed in the diet, the fish of the control group were additionally fed a meat mixture for freshwater fish, in the experimental group this mixture and part of the combined feed were replaced with organic food objects - swordtails in the amount of 0.75 g/head per day.
