    Fish culture is sometimes done in combination with a rice crop, so that fish are grown in the water in the paddy field. More intensive fish farming can be done in composite fish culture systems. In such a system, a combination of five or six fish species is used in a single fishpond. These species are selected so that they do not compete for food among them having different types of food habits. Example - Catlas are surface feeders, Rohus feed in the middle-zone of the pond, Mrigals and Common Carps are bottom feeders, and Grass Carps feed on the weeds, together these species can use all the food in the pond without competing with each other.

    Rutherford's model of an atom stated that the electrons revolved continuously as they possessed energy and would eventually lose energy and finally fall into the nucleus. If it was so then the matter wouldn't be in it's stable form and matter would not exist as we know .

    • Rutherford's Atomic Model:

     

    Based on the results of the α-particle scattering experiments, Rutherford put forth his atomic model. An  atom  contains  a  positively  charged  centre  called the nucleus  of  the  atom.  Almost  all  the  mass  of the atom is concentrated in the nucleus. The electrons of the atom revolve around the nucleus in fixed, circular orbits. The  size  of  the  nucleus  is  many  times  smaller  than  the  size  of  the  atom.  The  nucleus  of  an  atom  is 10,000 times smaller than the atom.
