A seine survey is a relatively easy way to learn about fish populations in impoundments and streams and to help improve management decisions. Seining is one of several fish survey techniques, which also include hook and line fishing, electrofishing, scuba diving/snorkeling, cast netting, gillnetting, hoop netting, fyke trap netting or fish trapping.
Appropriate water quality is fundamentally important for fish and aquatic plants, and muddy water limits production of both. Ideal clarity for largemouth bass and bluegill production in ponds without substantial vegetation is 12- to 30-inch visibility, with primarily phytoplankton turbidity. Turbidity is cloudiness caused by suspended or dissolved material. Sport fish also perform well in clearer water when substantial aquatic vegetation is present. Ideal clarity for aquatic plant production is generally greater than 36-inch visibility.
