Each Member State shall establish a sampling plan to implement the conditions laid down in paragraphs 1 and 2, indicating, inter alia, the distribution of observers among the geographical areas, and transmit it to the Commission for approval. 4. The observers shall record for each operation of the fishing gear, the mesh size of the trawl and the geographical location of the operation and shall implement an appropriately designed sampling procedure to estimate: (a) the total quantity by weight of hake, of Norway lobsters and of all other marine organisms caught by each operation of the fishing gear; (b) the length to the nearest centimetre below the absolute length of the hake caught by each operation of the fishing gear; (c) the total quantity by weight of hake, of Norway lobsters and of all other marine organisms landed; (d) the length to the nearest centimetre below the absolute length of the hake landed. 5. The master of a Community fishing vessel designated to receive an observer on board shall facilitate the arrival and departure of the observer and shall provide the observer with appropriate facilities for accommodation and work. 6.
