fish worship... is it wrong?

fish

The freshwater rivers, streams and lakes of the North American continent is the native land for roughly 800 native fish species in 36 families. 
North America has the most diverse temperate freshwater fish fauna on the planet.

Tennessee has >300 recorded species of fish.


what is a fish?Salmonidae Oncorhynchus

Fish are cold-blooded animals with a backbone, gills for breathing underwater, and paired fins for swimming.
Fish live underwater and depend upon water for dissolved oxygen, support, food and shelter.
Some people are surprised to learn that whales and dolphins are not fish.



brief discussion of anadromous versus catadromous fishes
-anadromous fishes
anadromous fishes live in the sea and enter freshwater to reproduce
"an", meaning "up", as in anabolic
once anadromous fishes enter freshwater, they stop drinking and begin absorbing salts

salmon are a example of an anadromous fish, as they will return to the very stream (and sometimes the same gravel bar) as where they were born.  Salmon suffer greatly from clear cutting of timber, shoddy logging practices, acid rain and farmed salmon


-catadromous fishes
cat meaning "down", as in catabolic
catadromous fishes inhabit freshwater, and move downstream to saltwater to reproduce/spawn, once catadromous fishes enter saltwater they initiate drinking, and they begin to secrete salts

Anguilla rostrata the american eel
Anguilla rostrata, is an example of catadromous fishes, as they spend most of their lives in fresh water, and after 40 years eventually migrate to the sea to spawn



Fish migrations range from daily migrations to annual migrations.
Some fish migrate only a few meters and other fish will migrate thousands of miles for either feeding or breeding, or other, still unknown reasons.
-diadromous fish travel between salt and fresh water
-amphidromous fish move between fresh and salt water during some part of their life cycle, but not as a function of breeding
-potamodromous fish migrate with fresh water only

fish matter greatly.  Fish are indicator species for humans. When fish suffer, humans are not far behind.

so any fish that makes the ocean a home, or a part of its life cycle is involved with Global Ocean Currents.

Lets consider Global Currents. ocean current drift
As the sun warms the earths surface and atmosphere, it drives convection within the atmosphere and oceans, producing winds and ocean currents. Differential heating of Earth results in circulation patterns in the atmosphere and oceans distributing heat globally. 
The rotation of the Earth affects the circular motions of the ocean currents and air pressure.
Surface currents are created by prevailing wind systems.
The ocean is one continuous body of water with global current systems that interact with water surrounding all landforms.  The primary source of oxygen for the deep sea is the cold polar bottom current.

The properties of ocean water, like temperature and salinity, are used to better understand the layered structures in the oceans and the generation of horizontal and vertical ocean currents, and the worldwide distribution of marine organisms.  Water density (as dictated by temperature and salinity), results in deep water currents. Example; at the north and south poles, very cold and salty water sinks to the ocean bottom and flows toward the equator.

Water on Earth is very old.
Water on Earth dates from the beginning of Earth and continues the hyrdological cycle of continuous recycling through the atmosphere, from fog to clouds, from water vapor or droplets to snow, hail, rain, and sleet.

Water and air behave similarly as fluids. Ocean currents affect the earth's climate and the flora and fauna on land and in the ocean. The Humbolt Current is the largest upwelling area in the southeastern Pacific Ocean. The Humbolt or Peru Current helps to create one of the world's most productive marine ecosystems, using a cold Antartic current which flows up the coast of Chile and Peru to move surface waters offshore, and cause upwelling of deeper nutrient rich waters, helping to sustain an extraordinary number of marine birds, mammals and fish.
