(4) On receipt of an application under paragraph (3), the British sea-fishery officer shall decide whether the sampling systems at the harbour are adequate for the purposes of monitoring effectively the landing of the catch having regard to the overall size and characteristics of the catch and shall notify the decision of that officer to the master.
