Answer 1

Answer: (A), (C)

The correct options are
A Mostly fishes breed only during monsoon.
C Lack of good quality seeds.

Composite fish culture involves combination of five to six species of fishes and all are cultured in a single pond. Species are selected so that they do not compete for food among them and have different types of food habits.
Disadvantages of composite fish culture are:-
$\bullet$ Many fish breed only in the rainy season so hormonal stimulation has to be given.
$\bullet$ Good quality seeds (i.e., organisms used for reproduction) are not available.
