Article 5
No vessel shall carry on board or use any trawl, seine, or other net towed or hauled at or near the bottom of the sea, which has in any part of the net meshes of less dimensions than those specified in Annex I1 to this Convention : provided that a trawl net made of single twine and containing no manila or sisal in any part may be carried on board or used by a vessel, notwithstanding that such a net has a minimum size of mesh 5 mm. less than the dimensions specified in Annex I to this Convention.
Article 6
Notwithstanding the provisions of Article 5, vessels fishing for mackerel, clupeoid fishes, sand eels (Ammodytes), smelts, eels, great weevers (Trachinus draco), shrimps, prawns, nephrops or molluscs, may carry on board and use nets having meshes of dimensions less than those so specified : provided that (a) any fishing instruments used by such vessels for the capture of any of the fish described in this Article shall not be used for the purpose of capturing other kinds of fish ; and (b) any fish in excess of the percentages set out in Annex III2 to this Convention, of the species set out in Annex III3 to this Convention, which may be captured by such instruments and which are of less than the minimum sizes prescribed in Annex II to this Convention shall be returned to the sea immediately after capture.
Article 7
(1) No vessel while operating shall use any device by means of which the mesh in any part of a fishing net to which Article 5 of this Convention applies is obstructed or otherwise in effect diminished.
(2) Notwithstanding the provisions of the foregoing paragraph, it shall not be deemed to be unlawful to attach to the underside of the cod-end of a trawl net any canvas, netting, or other material, for the purpose of preventing or reducing wear and tear.
Article 8
Subject to the provisions of Annex III to this Convention, no vessel shall retain on board any sea fish of the descriptions set out in Annex II to this Convention, of a less size than the size prescribed therein for each fish, and all such fish shall be returned immediately to the sea ; provided that they may be retained on board for the purpose of transplantation to other fishing grounds.

Subject to the provisions of Annex III to this Convention, each Contracting Government undertakes to prohibit by regulations the landing, sale, exposure or offer for sale, in its territories of any sea fish of the descriptions set out in Annex 11 to this Convention which are of a less size than the size prescribed therein for each fish and have been caught in the waters defined in Article I of this Convention, whether such fish are whole or have had their heads or any other part removed.
Article 10
The provisions of this Convention shall not apply to fishing operations conducted for the purposes of scientific investigation, or to fish taken in the course of such operations, but fish so taken shall not be sold, or exposed or offered for sale in contravention of the provisions of Article 9.
