Step-by-step explanation:
A reduction in the cost of inputs means that suppliers will avail more fish in the market. An increase in supply caused by other factors other than price shifts the supply to the right. A shift of the supply curve outwards or the right makes the equilibrium point to move to capture an increase in supply.
In the diagram, the new equilibrium point will be at point C. The supply will increase due to a reduction in input costs.
