A bottom feeder is an aquatic animal that feeds on or near the bottom of a body of water. Biologists often use the terms benthos—particularly for invertebrates such as shellfish, crabs, crayfish, sea anemones, starfish, snails, bristleworms and sea cucumbers—and benthivore or benthivorous, for fish and invertebrates that feed on material from the bottom. However the term benthos includes all aquatic life that lives on or near the bottom, which means it also includes non-animals, such as plants and algae. Biologists also use specific terms that refer to bottom feeding fish, such as demersal fish, groundfish, benthic fish and benthopelagic fish. Examples of bottom feeding fish species groups are flatfish (halibut, flounder, plaice, sole), eels, cod, haddock, bass, carp, grouper, bream (snapper) and some species of catfish and sharks.

Bream in the context of Vyatka River
The Vyatka is a river in Kirov Oblast and Tatarstan in Russia. It is a right tributary of the Kama. It is 1,314 kilometres (816 mi) long, and its drainage basin covers 129,000 square kilometres (50,000 sq mi).
The Vyatka begins in the northern parts of Udmurtia. It freezes over in the early November and remains so until the second half of April. The Vyatka teems with fish, including bream, roach, tench, sheat fish, pike, European perch, zander, etc.
Bream in the context of Salmon production regime
The aquaculture of salmonids is the farming and harvesting of salmonid fish under controlled conditions for both commercial and recreational purposes. Salmonids (particularly salmon and rainbow trout), along with carp and tilapia, are the three most important fish groups in aquaculture. The most commonly commercially farmed salmonid is the Atlantic salmon (Salmo salar).
In the United States, Chinook salmon and rainbow trout are the most commonly farmed salmonids for recreational and subsistence fishing through the National Fish Hatchery System. In Europe, brown trout are the most commonly reared fish for recreational restocking. Commonly farmed non-salmonid fish groups include tilapia, catfish, black sea bass and bream. In 2007, the aquaculture of salmonids was worth USD $10.7 billion globally. Salmonid aquaculture production grew over ten-fold during the 25 years from 1982 to 2007. In 2012, the leading producers of salmonids were Norway, Chile, Scotland and Canada.
Bream in the context of Bottom fishing
Bottom fishing, also called legering in the United Kingdom, is fishing of the bottom (demersal zone) of a deep body of water such as lake or ocean, targeting groundfish such as sucker fish, bream, catfish and crappie. It is contrasted with conventional angling in that no float is used with the fishing line.
