Temporary fish farm relocations require environmental studies, says Birdlife Malta
BirdLife Malta condemns the approval by the Environment & Resources Authority (ERA) and the Planning Authority (PA) of the relocation of tuna fish farming cages from an area close to Comino to a new site by l-Aħrax tal-Mellieħa, without the authorities requesting the Appropriate Assessment, mandatory under the European Habitats Directive.
While BirdLife Malta acknowledges the need to relocate fish farms to cause less pollution to beaches – a phenomenon which has been impacting water quality in various beaches and marine ecosystems – the application approved on Thursday did not carry the necessary prerequisities of siting such developments within marine Natura 2000 sites. In turn, the approval actually sanctioned an increase in the number of fish cages (from four to six) than what was originally permitted at Comino.
The application in question relates to a temporary relocation of tuna pens from the south Comino channel to a site approximately 6km offshore near Sikka l-Bajda, until a north aquaculture zone is set up by the Department of Fisheries.
The chosen location is within two designated marine Natura 2000 sites which qualify as both a marine Special Protection Area (marine SPA) for seabirds under the Birds Directive, and as a marine Special Area of Conservation (marine SAC) under the Habitats Directive.
Article 6 (4) of the Habitats Directive states that Natura 2000 sites require specific conservation measures and if plans or projects do not contribute to the conservation objectives of the site, they will be subjected to an Appropriate Assessment of their implications for the site in question. Plans can be approved only after it has been ascertained that these will not adversely affect the integrity of the site concerned, and, if appropriate, after having obtained the opinion of the general public.
In this week’s approval, ERA and PA did not follow this directive by not demanding any impact assessment of the proposed development. In fact, according to ERA, the proposal did not qualify for the need to have an Environmental Impact Assessment or Appropriate Assessment, because the relocation is just a temporary two-year solution.
Although a two-year period could be enough for the proposed fish cages to exert an impact, the proposal may also have various other concerns such as those listed below:
(i) The area is within the rafting zone of Yelkouan Shearwaters, which occupy their largest colony (estimated at 3% of the world population) at the cliffs of Rdum tal-Madonna. This is one of the reasons why the area is designated as ‘Il-Baħar tal-Grigal’ marine SPA. It is not known how fish farming activities will affect the species as no impact studies have been carried out
(ii) The sea bed beneath the proposed fish farms constitutes protected maerl grounds which are part of the ‘Il-Baħar fil-Grigal ta’ Malta’ SAC. Despite consultants mentioning during the PA’s hearing that the immediate area of the fish farm has a sandy bottom, its effect or impact on surrounding maerl habitat still has to be appropriately assessed
(iii) No assessments were presented on the possible damage caused by tuna farms at Comino to the marine environment in the past in order to predict the impacts these might exert elsewhere
(iv) Despite the concerns raised over the years from government authorities and the general public about the impact of fish farms on water quality, it is understood that no changes to aquaculture practices are being imposed
(v) ERA and PA have raised no objection over the fact that the developer in question did not comply with a previous planning permit and have actually sanctioned a larger amount of cages in a new area.
While development in the area was scrutinised for the then proposal to erect wind turbines, this time round ERA and PA have not raised similar concerns or objectives.
In the end it is unclear what permit conditions have been imposed on the developer to ensure that environmental impacts are contained, and that the developer complies to permitting conditions. BirdLife Malta states that such conditions should be made public.
