A common rig for fishing on the bottom is a weight tied to the end of the line, and a hook about an inch up line from the weight. The method can be used both with hand lines and rod fishing.
The weight can also be used to cast or throw the line to an appropriate distance. Bottom fishing can be done both from boats and from the land.
Bottom fishing targets groundfish such as sucker fish, bream, catfish, and crappie. Specialized fishing rods called “donkas” are also commonly used for bottom fishing.
In Share Market terminology, Bottom fishing is simply buying the cheapest investments (in terms of valuation ratios) available. Bottom fishing is value investing concentrated on the very cheapest companies. The term can be derogatory as it can imply a lack of attention to the quality of the investments selected
