to help combat the potential for oil pollution and the pirate attacks themselves. The levy would apply to vessels in the South China Sea and Malacca Strait. The money raised from the levy would be used to finance the, purchase of pollution surveillance aircraft, which had previously been shelved due to lack of funds, and to put police guards on merchant vessels in those waters. Senior shipping industry figures warned that there would be strong opposition to the levy amongst shipowners as they believed that it is the duty of governments to ensure safe passage for vessels in their waters and not that of the shipowners themselves. The UK Ministry of Defence (MoD) is considering mounting a Royal Navy patrol to escort UK-registered ships through the Strait of Malacca. This will come into effect if the current MoD intelligence gathering network fails to deter merchant ship attacks. The patrol could result in an increase in shipowners transferring to UK dependent terriroty registers so as to receive extra protection. This occurred during the last months of the Iran-Iraq war when the Royal Navy escorted UK registered ships through the Persian Gulf. As warships are capable of seizing pirate ships under international law it could mean that pirates arrested by the patrol could stand trial in Britain. PHILIPPA A M B R O S E
Europipe Objections There is growing opposition in Germany to the proposal by the Norwegian State Oil Company, Statoil, to build a pipeline to bring gas from Norway's offshore fields into Germany. The problem is that the S1.5 billion 650 km pipeline would have to cross the German National Sea Park in the environmentally sensitive Wadden Sea. Environmentalists opposing the scheme fear that the construction and presence of the pipeline will permanently disrupt the shallow Wadden Sea which is an important wildlife refuge. The company wishes to dig a trench through the wetlands and then fill it in, taking about six months. Greenpeace Germany suggests that at least a tunnel should be built under the wetlands, although they favour a detour around the 450 km coastal area of Germany, Denmark and the Netherlands, keeping the pipeline away from environmentally sensitive areas.
Mass Produced Cod Fry could Improve Sea Stocks Mass producing and releasing young cod, turbot and plaice may prove an effective method of enhancing stocks of marine fish according to a recent report in Fish Farming International. Denmark is now increasing its efforts to determine whether a large scale programme of release could be cost-effective. The Danish Institute for Fisheries and Marine Research 332
(DIFMAR), working with the fisheries associations is producing and releasing young cod into the Baltic Sea from Bornholm Island. With this year's fishing season described as 'catastrophic' by Philip Prince, the DIFMAR fisheries biologist leading the project, the new scheme of mass producing and releasing fingerling cod could rescue the livelihoods of thousands of fishermen in the Baltic States. The project follows the principle that fingerling cod, already between 3-7 cm, would not suffer such heavy predation from herring, bristling and cod itself, and thus more fish would survive to become available as recruits to the fishing industry. DIFMAR will rear 200 000 cod fry at their new hatchery at Nesko on Bornholm's east coast. One group will be reared intensively on rotifers and Artemia while a second group will be semi-intensively reared on natural zooplankton filtered from the sea. The fingerling fish will be released into the North Sea and Limfjord. Another project in conjunction with the South Jutland Electricity Generating Company will produce 200 000 plaice and 10 000 cod to enhance stocks in Denmark's inner seas, while the Sea Fishery Association plans to produce one million cod and 400 000 turbot, all in the 3-7 cm range, for release into the North Sea. Other projects are also underway. Enhancing marine fish stocks is not a new idea. As long ago as 1892 plaice were transferred from areas of high nursery stock density near Thyboron to low density areas in inner Limfjord where the conditions gave potential for rapid growth. The results were good, with improved growth rates, enhanced recapture and no evidence for migration from Limfjord. This project was discontinued in 1957. However, in 1988 over 9000 plaice between 14-31 cm were transplanted to the Kattegat in a scheme to determine whether North Sea stock would establish themselves there. Two thousand of the fish were tagged. The recapture rate in the area was very low, between 35% with most fish found to have migrated to Skagen in the Skagerrak or into the North Sea. This experiment demonstrated the complexity of activities of this nature. However the concept of fish enhancement is being taken very seriously and if the DIFMAR project is a success the Danish Ministry of Fisheries will build a much larger hatchery for mass production of cod fry. It is proposed that such a long term project as well as being funded by public money may expect fishermen themselves to pay towards some of the costs through a proportion of their earning from fishing trips.
