Often used synonymously with lacustrine (oradfluvial-lacustrine) to describe fish that spend most of their lives in lakes, typicallymigrating into streams to spawn. Juveniles generally reside within streams and thenmigrate into lakes as subadults.adfluvial-lacustrine: Refer to definition for adfluvial.agonistic: A threat, offensive movement (aggression), or retreat (appeasement) directedat another member of the same species. Agonistic behavior is often associated withterritorial behavior, where a space is defended.allopatry: Refers to populations or taxa whose ranges do not overlap (i.e. populationsare geographically separated).alluvial fan: A type of floodplain, typically located at the mouth of a tributary valley,created when sediment is deposited by flowing water. Usually results from decreasedwater velocity, increased sediment content, or changing channel form with the resultinglandform resembling a cone or fan shape.anadromous: Fish which spend most of their life in the sea and which migrate tofreshwater to reproduce.anthropogenic: Involving the impact, usually negative, of mankind on nature.benchmark: A defined reference mark, used to measure change.biological oxygen demand (BOD): A measure of the quantity of oxygen needed toincorporate organic waste material into the environment or, alternatively, a measure ofoxygen consumption over a fixed time period. A high BOD will generally restrict thediversity of fish.creel: A creel is a survey of recreational anglers to gather information on a fishery. Theorigin of this term is from the word’s original use as a wicker basket used by anglers tohold fish.
