PPT-Salinity and Buoyancy: Fish Swim Bladder

httpwwwscienceisartcomBSwimBladderSwimBladderhtml Buoyancy T he relationship between density of a fluid weight of an object and buoyancy is an absolutely basic concept for all students of the sea or fresh waters because density directly affects everything in the water.

Fish Characteristics. All fish are . ectotherms. . They can live in any water habitat. . Some fish have the ability to live part of their life in fresh water and part in salt. . Most fish can move quickly because they have a muscular tail and fins. Fins are fanlike structures used for steering, balancing, and moving. Paired fins on the left and right of the fish allow them to move right, left, backward, and forward. Fins on the top and bottom give stability. . Section 1 - Buoyancy Guide 1.1 Intro Buoyancy is defined as the tendency of a fluid to exert a supporting upward force on a body placed in a fluid (i.e., a liquid or a gas ) .

Many fishes have well-developed eyes and a keen sense of vision that they rely upon to find and capture food, avoid predation, locate shelter and find a mate.
