What grass do bream like to eat? Introduction to common grasses for feeding in aquaculture

Bream is a relatively common food fish, with tender and smooth flesh and a delicious taste, loved by many people, and has become one of the main freshwater aquaculture fish species, so what grass do bream like to eat?

1. What grass do bream like to eat?

Bream like to eat aquatic vascular plants such as bitter grass, Hydrilla verticillata, and Potamogeton, and also like to eat terrestrial gramineous plants and vegetable leaves, and can also ingest some lake-bottom plant debris and a small amount of zooplankton, with a wide feeding range. They begin feeding in April and continue until November, with the largest amount consumed from June to October.

The feeding habits of bream are similar to those of grass carp; they can economically utilize the bait resources in natural waters, and can also consume artificial feed to promote the growth of adult fish. Bream are mainly distributed in the medium-sized lakes attached to the middle and lower reaches of the Yangtze River in China.

2. How are bream raised?

Farming methods include pond monoculture or polyculture, extensive farming in lake and reservoir waters with abundant aquatic plants, and intensive farming using cages. For monoculture of bream, in a pond with a water depth of 1.5-2 m, 600-800 winter fingerlings can be stocked per mu, with 200-300 silver carp and bighead carp fingerlings as companion species; after one year of rearing, individual bream can reach about 500 g. The growth rate is relatively fast before the age of three years, then gradually slows down. The feeding habits of bream are similar to those of grass carp, so they can economically utilize the bait resources in natural waters, and can also consume artificial feed to promote the growth of adult fish. In a trial pond in Wuhan, monoculture of bream achieved very good results; the method was: stocking 1,220 overwintering bream fingerlings weighing 40 g each per mu, with 200 silver carp fingerlings weighing 50 g each and 30 bighead carp fingerlings weighing 60 g each as companion species, and also appropriately stocking some high-backed crucian carp fingerlings, using “Zhengda” No. 083 feed, with a feed coefficient of 1.8, broadcast evenly by hand when feeding. Usually pay attention to water quality management to prevent water quality deterioration and pond fish kills, and the dissolved oxygen in the pond water should not be lower than 2 mg/L day and night.

Bream has a delicious taste and very high edible value, is suitable for most people to eat, and is a very good fish species.
