Vol. 408 No. 9

Adjournment Debate. - Sea Trout Infestation.

There was a lovely run of sea trout smolts in Connemara this year. Everyone had hoped that the cold winter and cool spring would mean that the sea lice problem would not be as bad this year as it was in the past three years and that, consequently, the smolts would be able to get safely to the open sea where they could feed and grow. Unfortunately this was not the case. More smolts have returned prematurely to fresh water this year than in previous years and have come back in worse condition. Moreover, the returned smolts are absolutely teeming with sea lice, as is evident from the photograph in The Irish Times of yesterday.

There is little doubt that the salmon farms are responsible for the rise in sea lice numbers and the other problems now facing sea trout. Dr. Edward Fahy's climatic theories for the decline of sea trout have now been thoroughly discredited and the notion that disease or acidification as a result of afforestation could be responsible for their decline will be eliminated within the next two months. Even scientists in the Department of the Marine who have been reluctant to blame salmon farming for the decline in the number of sea trout are privately beginning to do so. It is apparent that the Minister for the Marine has refused to accept the evidence which proves that salmon farms are guilty of causing this decline.

Although it is now too late to prevent this disaster which has cost the economy of the West far more in income and employment than is currently provided by salmon farms, the Minister must now undertake to do five things in an effort to salvage as much as possible from this environmental disaster. First, he must give an undertaking to implement the main recommendation of the STAG report which was that fish farms which are unable to control their sea lice problem should be closed down. He should make it clear to the industry that he intends to do this and that he will order the cages of offending farms to be removed at least three months before next year's run of sea trout smolts in order that the sea lice population time can be reduced.

Secondly, he must give adequate finance to the regional fisheries boards to police the sea trout protection by-laws he has introduced. Last year Michael Kennedy, the manager of the worst affected board, the Western Board, was able to employ 15 summer staff to help protect the remaining sea trout and enforce the regulations. However, he does not have adequate funds this year to take on even one protection officer for the summer. Is the Minister serious about fishery protection or is he just too weak to negotiate funds from his colleagues? Thirdly, the Minister must ensure that adequate funding is made available to STAG so that they can continue their research into the causes of this disaster and restock affected rivers.

STAG have requested information from the Minister's Department about the history and records of some of the fish farms in the affected areas but to date they have not seen fit to release this information. Will the Minister say why this information has not been released?

Finally, the Minister might like to tell the House what he intends to do for all those people in the West who have lost all or part of their livelihood as a result of the sea trout collapse. He can no longer pretend that the decline of this fine fish is an act of God. It was a result of acts of man, of the over-rapid expansion of a new industry long before anybody knew what the environmental consequences might be. For allowing this, the Government were responsible and the Government must pay.

, Limerick West): First, I reject utterly any suggestion that there has been inaction on my part or that of my colleague in the Department of the Marine in relation to this matter. The Minister for the Marine dealt fully and comprehensively with the development of the problem with sea trout stocks that has arisen in the West over the past few seasons when this issue was last raised on the adjournment in this House on 14 February. During the course of his reply on that occasion the Minister outlined the action that had been taken up to that stage by the Department in response to the problem and referred to the report that had recently become available from the Sea-Trout Action Group.

A considerable number of the protection measures for sea trout stocks that were sought in that report have since been introduced. By-law No. 670 of 1991 reintroduced the prohibition on the retention, possession or sale of sea trout that was first introduced in 1990 and extended the area in which that prohibition applies. By-law No. C.S. 161 of 1991 introduced a much shorter open season for sea trout angling for 1991 in the areas covered by By-law No. 670. By-law No. 672 of 1991 extended the boundaries of the existing sanctuary areas where drift-netting for salmon and sea trout is prohibited in the western fisheries region. It also created a number of new sanctuary areas and prohibits drift-netting for salmon and sea trout within 200 metres of the coast in the same region.

These measures go a considerable way towards meeting the requests made by STAG in their report and I understand that members of STAG have expressed their appreciation of the measures in question and the alacrity with which they were taken. My Department continue to look at further measures put forward as being helpful to conservation of sea trout stocks but as the Minister indicated on 14 February, some of these cannot be dealt with immediately as they call for changes in legislation.

The foregoing puts paid to any suggestion that anyone in the Department of the Marine has been inactive in this matter. The Deputy should further note that an expanded research programme has been put in place for 1991, with increased funding from my Department, which will look into: (a) the physiological mechanisms involved in sea trout's transition from freshwater to the sea; (b) possible differences in the selected physiological parameters between depleted sea trout stocks and those less severely affected; (c) the dynamics of relevant brown trout populations, including interactions between the resident and sea run components of these stocks; and (d) the role of sea lice in relation to the above. My Department have also instituted a programme of inspections of salmon cages with a view to assessing sea lice densities.

I hope that this research effort will enable my Department to identify the root cause of the problem and I am sure the Deputy and the House generally will share my aspirations in this regard.

The Deputy in his opening remarks suggested that some new facts had come to light in relation to and cause of the problem. That is not so. What has become clear in recent weeks is that the problem is a continuing one and that certain hopes that had been entertained that improved weather and water-flow conditions this spring would have improved the situation have not been realised. This is not a new problem. It is a seasonal one and only manifests itself when young sea trout migrate to the sea in April-May and adults return in May-June. As soon as it became apparent that the problem was recurring, my Department moved quickly and decisively and mounted a rescue operation in close co-operation with STAG and the Western Regional Fisheries Board in order to trap and retain as many as possible of the remaining sea trout smolts and adults in order to ensure a continued spawning stock in the affected rivers in years to come.

I think it is clear from all I have said that my Department have responded quickly, decisively and positively to the requirements of the situation here.

That was a disgraceful and most inadequate reply. The Minister should resign at once.
