Vol. 139 No. 4

Adjournment Matter. - Salmon and Sea Trout Stocks.

I welcome the Minister to the House. I know this matter will become controversial for him in the months to come. If some of the people who have been writing to him have anything to do with it, it is a subject in which he will be embroiled in a different arena, especially coming up to June. I wish him the best of luck in solving this problem; undoubtedly he will do his best to resolve it.

As the Minister knows, a very strong campaign called SOS is being launched to save our sea trout. There has been a depletion in sea trout stocks over the last five years particularly on the west coast — from Donegal to Cork. This will have a very dramatic effect on our tourist industry and on employment.

We have a problem here. It will be very interesting to hear what the Minister has to say on this subject because we have two conflicting industries fighting. The wild angling industry and the salmon farmers are at odds on this issue. Every Senator will have been lobbied by both groups. May I share my time with Senator Norris?

An Leas-Chathaoirleach

Is that agreed? Agreed.

Will Senator Ross give me a minute of his time?

Of course. I would be delighted to accommodate the Senator.

An Leas-Chathaoirleach

I take it then that the three Senators are sharing their time.

Correct. One of the great problems with this issue has been the tendency of the Government to address it in palliative way. The salmon farmers say there is no proof of a connection between sea lice and salmon growing and the destruction of sea trout. I suppose one can compare that to the argument made against smoking. It is not possible to prove that smoking causes lung cancer but the statistics are very compelling. In this case precautionary measures are absolutely necessary from the point of view of the Government. It is no good asking for more research and statistics or for more information when these stocks are being depleted in an appalling way. Because of what is happening here the Government's prime objective of giving employment is suffering. As a precautionary measure the salmon farms should immediately be relocated a distance from the estuary supporting the migrating fish population. That would be sensible and it would not put the salmon farm growers out of business, but it would reduce the numbers of wild salmon being infested by lice.

Research overseas shows that there is an extraordinary connection between these two industries. Nobody is asking that one industry should destroy the other, we are asking that they live together on terms which are to the benefit of the wild trout. A Daly Kelleher McCarthy report is due to be published next month. Before then the Minister should introduce measures to regulate the salmon farming industry. I also ask him to announce today what work has been done by the sea trout task force. After five years we are a little tired of having task forces set up to solve an urgent problem.

I am grateful to my colleague Senator Ross for sharing his time with me.

This is an important matter. Senator Ross and I both received communications from the proprietor of a hotel in Connemara who had to close an important fishery because of the infestation of sea lice. He made the very cogent point, which has been already stated by Senator Ross, that this has a substantial impact on tourism and on that industry in the west. He instances the spin-off effects, such as loss of income to hoteliers, car rental agencies and publicans. That income is assessable in terms of millions.

I will be brief because Senator Daly wishes to speak as well. I wish to put a couple of points on the record with regard to the clarity of the evidence. A report in The Irish Times on Tuesday, 8 February, made it clear that an increase in sea lice caused the sea trout stocks in County Galway and County Mayo to collapse according to the Western Regional Fisheries Board, an independent body, which determined this by examining and removing from consideration all other factors which had been proposed by the Irish Salmon Growers' Association, with which I have a certain amount of sympathy.

The available evidence points to an increase in sea lice lava production arising from salmon farms with consequent lethal infestation of migrating sea trout as being the sole cause of the sea trout stock collapse. This is clear when one considers that sea trout stocks are unaffected in areas where there are no intensive salmon growing facilities. As soon as intensive salmon farming facilities are established, the infestation of lice passes from the cages into the sea trout stock. There is no doubt about the evidence. One has sympathy for the salmon growers but there is no doubt about the scientific cause and relationship.

The evidence is not clear. There is no evidence to support the theory that sea lice have been the major factor in the decline of sea trout stocks.

The Senator is challenging the Western Regional Fisheries Board.

Sea trout stocks have declined on numerous occasions over the past 100 years. Anyone who has studied the records——

They have not collapsed.

——will see that sea trout stocks declined over periods of four to five years long before fish cages were introduced into the coastal environment.

Nothing like this has happened before.

It happened before and the reason given on that occasion was that the small herring mesh nets were depleting the stocks. At that time a big campaign was organised to stop the herring fishery because of the damage it was doing to the trout stocks. There is no doubt that netting in the estuaries has been a major cause of the decline in sea trout stocks and the Minister acted on this a few years ago by banning the widescale netting of sea trout stocks in estuaries.

Sea lice have been part of the marine environment since time immemorial. It is a matter of opinion as to whether they have expanded adjacent to cages——

It is a matter of statistics.

Sea lice are present where fish congregate. Sea lice have always infested wild salmon. Salmon go into the fresh water to shake off the sea lice because the sea lice die there.

They commit suicide.

Sea lice have been part of the marine environment. In relation to this issue, the great tragedy is that when efforts were made to find the finance to undertake research in this area, many of the people who are loudly criticising the decline in sea trout stocks today objected to the provision of that money necessary to undertake the vital research work which needs to be done in this area——

The Senator is challenging the Minister's research.

——to establish what is happening rather than accepting irresponsible statements which have no evidence, factual or scientific, to support them.

An Leas-Chathaoirleach

I welcome the Minister of State to the House. He has a busy year ahead of him. I wish him good luck.

Donegal South-West): Ba mhaith liom mo bhuíochas a ghabháil do na Seanadoírí Ross, Norris agus Daly as ucht an méid a bhí le rá acu.

Is doígh nach n-aontaíonn gach duine leis an méid a bhí á rá ach, ag am céanna, tá sé tábhachtach go dtiocfaimís isteach anseo agus tionscal tábhachtach mar seo a phlé.

The preservation and enhancement of our wild salmon and sea trout fisheries and the proper exploitation of this valuable natural resource is a key policy objective. A variety of conservation, protection and management strategies are in place and are under continuous review to ensure that this objective is realised. All the reports indicate that 1993 was a good year for wild salmon stocks and that strategies implemented in recent years to conserve, rehabilitate and protect stock levels are paying dividends.

A considerable number of legislative controls are already in place and these are designated to ensure that the maximum number of salmon return from their feeding grounds at sea to their breeding grounds in fresh water by restricting the fishing effort of commercial salmon fishermen at sea. These controls include restrictions on the number of licences made available to fish for salmon, no fishing at weekends and at times when breeding takes place, restrictions on the maximum lengths and depths of nets and the material allowed to be used in them, extensive sanctuary areas where no fishing is allowed at any time and an absolute prohibition on fishing for salmon beyond the 12 mile limit.

It is important to note the varying degrees of weather during the salmon season. If the weather is too calm the nets do not drift and if the sea is too heavy the nets rope. A natural type of conservation exists in addition to the legislative means used for conservation purposes.

The Department of the Marine is conducting a review of all aspects of salmon fishing with particular reference to drift netting. We would like to see fishermen and drift net fishermen, who have no other source of income, working each day in a calm environment, but in order for this to happen it will be necessary for all parties to agree a strategy. This situation develops every year during the months of June and July and now is the time to do something about it. I will recommend to the Minister for the Marine that all parties — the regional boards, the fishermen and officials from the Department of the Marine — should enter into discussions in ample time for the next drift-net fishing season.

I have no doubt there will be full cooperation in relation to improvements in the existing regulations. Enforcement of the salmon fishing regulations has been stepped up considerably in recent years. Some people might say it is too severe, but others feel it is not severe enough. Extreme views are held by many people, but there is room for compromise and manoeuvre. The regional fisheries boards, which have the primary responsibility for ensuring compliance with the regulations, have been equipped with a number of fast patrol boats specifically for this work. The Department is at present examining additional ways in which the boards' capability can be further enhanced with the benefit of significant levels of EU Structural Funding being provided for angling tourism.

The Naval Service enforces the prohibition on salmon fishing outside the 12 mile limit on a year round basis as part of its general enforcement of EU regulations. It also dedicates its two fast inshore patrol vessels full-time to aiding the fisheries boards in enforcing the salmon regulations within the 12 mile limit during the summer months when the main salmon run is taking place.

The decline in sea trout stocks is a cause for considerable concern and measures to address this decline are being further enhanced for 1994. A number of sea trout fisheries in the west have experienced declines in recent years with a severe collapse in stocks in 1990. A scientific working group was established in 1991 to co-ordinate the national sea trout research programme, evaluate the results and recommend action to halt the decline of stocks. Its report for 1993 will be published shortly.

To date the research effort has not identified a single definitive cause for the decline in sea trout numbers. Various views may be held by many people, including Senator Ross and Senator Norris, but I must also take seriously Senator Daly's views because he was an experienced Minister for the Marine. We must accept there is no definite cause but we must try to establish one.

Some of the Minister's own working group has established a cause.

(Donegal South-West): The research effort to date, irrespective of what has been said, has not identified a single definitive cause for the decline. The widely held perception that there is a casual link between sea lice infestations at salmon farms and the localised demise of sea trout populations has not been proven; it may be a view but it has not been proven. However, in addition, to determining the research priorities each year, the scientific working group advises on the precautionary measures needed to conserve and rehabilitate sea trout stocks and on management strategies for salmon farms. These measures have been put in place.

A programme of precautionary action to address the problem of sea trout declines in the west has been in operation since 1991 under the following key headings: conservation and protection of existing stocks; rehabilitation of stocks; improved management strategies for fish farms; and continuing research into the causes of sea trout declines. Further intensified action under all these headings will be undertaken this year.

The extent to which fish farm management strategies have been improved can be gauged from the substantial reduction in sea lice numbers at farm sites which are regularly monitored. The regional fisheries boards are to address as a priority this year the major gaps in historical and actual data on sea trout stocks in individual fisheries.

To augment the action programme, and on the principle that different perceptions as to the causes of sea trout declines should not stand in the way of a concerted effort to address the problem, the Minister established a sea trout task force in July 1993 to advise on additional measures necessary to combat the sea trout decline. Dr. T.K. Whitaker assumed chairmanship of the task force in October. The conclusions in an interim report by the task force in November have already been acted upon and its final report is expected before Easter.

I appreciate that there are difficulties in relation to sea lice and sea trout declines. There is no scientific evidence of such a link but we are all interested in ensuring that we halt this decline and continue to develop our fisheries, because they are so important to the economy and to everybody working in the sector. This is a recurring resource which as far as the deep sea sector, inland fisheries and tourism are concerned, is vitally important.

I thank Senators for their contributions. I too am looking forward to reading the final report which we expect before Easter.

A Leas-Chathaoirligh, I think I am allowed a supplementary.

An Leas-Chathaoirleach

One very brief question from Senator Ross.

I thank the Minister for his reply, although it was disappointing. He said he looks forward to these reports; so do we all. However, what I would like from him is a pledge for action. There are two reports coming that I know of, maybe more. We have already had the western fisheries report which should have prompted action, but next month there is a report due from DKM which, even if it cannot prove them, will express strong opinions. There is also the report of the task force. If the task force and DKM express the opinion that the salmon farm growers are the cause of this problem, will the Minister act accordingly?

(Donegal South-West): It would be wrong to assume what might be in the report of DKM or any other report. We should await the outcome of that report. As responsible as Senator Ross is——

I am not and never was.

An Leas-Chathaoirleach

You said it.

(Donegal South-West): ——I think it might be wrong at this stage. The House realises the importance of farm fisheries. They have made a tremendous contribution to the economy, particularly in areas along the coast where there is no alternative source of income. Let us await the outcome of the reports and then decide on the action that should be taken.

The Seanad adjourned at 4.25 p.m. until 2.30 p.m. on Wednesday, 16 February 1994.
