Practical experience in Koi keeping - "three highs and three lows"

How should I care for my koi now that I've safely survived the winter and spring is in full swing?

Breeding begins with observation. Regularly check the koi pond in daily management: whether the pond filtration equipment and pump are running normally, whether the filter tank is clogged with dirt, whether the ultraviolet germicidal lamp is working effectively, whether there is any leakage in the pond, and whether there is any abnormality in physiological characteristics of koi.

In order to raise koi to understand, in addition to the above daily management, need to do "three high and three low".

        In Guangzhou nowadays, the daytime temperature ranges from 25°C to 30°C, which is the optimal temperature for koi growth. In this optimal temperature range the fish have the most digestive enzymes in their body, the activity of digestive enzymes is strong, so the fish have the most vigorous intake, strong digestion, high digestibility, and their metabolism level is also high, so the fish have the most vigorous growth, which belongs to the so-called peak period.

        Under the condition of outdoor ponds, with the use of high quality feed normal feeding and normal intake of fish, the digestibility of the feed is only about 80%, feeding feed only 25-30% of the protein for the growth of fish. Taking into account the effects of various factors, it is generally true that 20% of the major nutrients in the feed consumed by the fish are digested and excreted as part of the feces, 30% of the protein is used for growth, and 50% of the protein, essentially all the absorbed carbohydrates, and most or part of the fat is used for life support and activity.
