Any person who is found in possession of fish which has been captured with the aid of any explosive or poisonous substance and does not give a satisfactory account as to how he came to be in possession thereof, shall be guilty of an offence under this Act.

When any poisonous or explosive substance by which fish can be stupefied, poisoned or killed is found in the possession or control of any person in the neighbourhood of any waters shortly after the use of such substance in such waters, such person shall be presumed until the contrary is proved to have made use of such substance for the purposes aforesaid.

Any person in a fishing boat who is found to be in possession or control of any poisonous or explosive substance without a licence shall be guilty of an offence under this Act.
