Water is life ! It is a precondition for human, animal and plant life as well as an indispensable resource for the economy. Water also plays a fundamental role in the climate regulation cycle

C&R primary environmental meaning is conservation: it protects fish populations from overharvesting, maintains balanced aquatic ecosystems, and ensures breeding fish remain in the gene pool to spawn future generations.

Water bodies, particularly flowing river systems, are classified depending on their longitudinal zonation, which is primarily determined by physical characteristics like temperature, flow velocity, and oxygen content

In an ecosystem lots of different organisms interact with each other. The living organisms can be divided into three categories: producers, consumers and decomposers.
