Fish that begin their life in freshwater, travel to and mature in the sea, and return to their native stream to reproduce and die. i.e. pacific salmon.
Captured marine organisms that are not the target species. (Tuna fishers accidentally netting a dolphin)
the bycatch that are thrown back for non target fish, endangered, juvenile, wrong size, inferior quality, or surplus to quotas
live their entire life in freshwater sometimes confined to a lake tributary or stream
water depth and velocity
habitat requirements for fish
cloudiness or haziness of a fluid caused by large numbers of individual particles that are generally invisible to the naked eye,
the natural environment in which an organism lives, or the surface or medium on which an organism grows or is attached.
natural limitations for fish
human interference for fish
fishery technique where gears are left in place for a period before retrieval. They may either attract fish using bait, or may passively wait for a fish to swim into a net or trap. Gill nets, longlines, traps and pots.
fishery technique where mobile gears are moved in order to catch fish by trapping or encirclement.
These gears can be divided into those which are towed along the seabed
