To mark the new decade, Lord Sanderson of Bowden, Min- ister of State for Agriculture, Fisheries and Forestry at the Scottish Office, looked back at what the ’80s had signified for the aquaculture industry and forward to what the next 10 years might have to offer. ‘Worldwide,’ the Minister reflected, ‘the pressures on commercially exploitable spe- cies of fish are all too obvious. By creating new stocks, aqua-

soundtrack was probably best remembered for Pavarotti’s gut- busting rendi- tion of ‘Nessun Dorma’. None shall, indeed, sleep if they find themselves near the great Italian tenor when he’s on song. Mean- while, back at home, the Iron Lady lost her vice-like grip on power, to be re- placed by a man who, if Spitting Image was to be believed, liked nothing more than cricket and conversing with his wife about peas.

History, we are told, has a habit of repeating itself. Were you to turn to page 44 of our May/ June issue in 1990, this theory would be borne out, for it reveals an article about the possibili-
Warming warning
While concerns about global warming are top of the public’s worry list these days, the first feature on the subject to appear in Fish Farmer was in our September issue of this year. Penned by Steven Drummond Sedgewick, he pointed out that changing sea temperatures and levels, might have a catastrophic effect on mariculture – unless, of course, we adapt. Sedgewick then mentioned the potential benefits of diversification into farming species such as gilthead seabream or seabass. While this might have seemed premature to many, he cited the example of a large rainbow trout farm in the English Channel, which had had to cease operations because sea temperatures had remained too high for too long. While Scotland may not have yet suffered to such an extent, it seems his predictions may well have been more far-sighted than many would have guessed at the time.

ties presented by using wrasse to clean sea lice from salmon. The tendency of wrasse to clean other fish had only been discovered in 1973 and, by 1988, their effectiveness had been assessed by a trial in Shetland. This reported that each wrasse accounted for up to 78 lice per day. What’s more, the trials also showed that salmon de-loused by wrasse showed better growth than those treated with organophos- phate pesticides and that it was both cheaper and less laborious than chemical treatments. As a further benefit, the wrasse, which had previously been a worthless bycatch of lobster fisheries, became a target for local fishermen, who were selling them for 45p apiece.
culture provides a source of self-sustaining supply for the future.’ ‘The value and scale of development of salmon farming and trout farming,’ observed the peer, ‘has been the most obvious feature of the 1980s…but a special mention ought to be made of shellfish cultivation, not least because of the variety, and opportunities for smaller producers, which it brings to the scene.’
