Salmonid fishes viz. pacific salmon (oncorhynchus sp.) Atlantic salmon (Salmo sp.)
Trouts are grown in cold areas of world. Both pacific salmon & Atlantic salmon are Anadromous fishes and they need saline environment for growth.
But trouts can be grown in inland waters.
Contribution of salmonid to global aquaculture production of fishes is next to that of carps. Hundreds of hatcheries operate in several parts of cold areas of the world which are meant not only for providing stocking materials for aqua farms but also for stock enhancement in natural waters through ranching.
Hatcheries of oncorhynchus and Salmo sp.Are engaged in the production of smolt for farming and ranching.Trouts hatcheries are established in several cold regions of the world including India. In India trouts were introduced from other countries. Mahseer found in the cold streams and lakes are endogenous fishes in India.

How much force is needed to accelerate a
1400 kilogram car 2 meters per second/per

18. If mass remains constant, doubling the acceleration, doubles the force. If force remains
constant, doubling the mass, halves the acceleration.
19. Newton’s 2nd Law proves that different masses
accelerate to the earth at the same rate, but with
different forces.
• We know that objects
with different masses
accelerate to the
ground at the same
rate.
• However, because of
the 2nd Law we know
that they don’t hit the
ground with the same
force.
