To ask the Scottish Executive whether all egg producers in Scotland are compliant with the Welfare of Laying Hens Directive and, if not, how many producers are non-compliant and what action is being taken to ensure compliance.
Answer
I am pleased to confirm that the last Scottish producer to have laying hens in conventional cages contrary to the requirements of the Laying Hens Directive had removed the hens before 1 February. All egg producers in Scotland now comply with the ban on keeping hens in conventional cages that came into force on 1 January.

To ask the Scottish Executive what impacts on benthic invertebrates have been recorded in the areas assessed by the Scottish Environment Protection Agency reports, JT000811_JT and TR110810_JT, since they were published.
Answer
There have been no surveys of benthic invertebrate populations undertaken in the six weeks since the publication of these reports. SEPA has however a range of data on the benthic invertebrates in the relevant waterbodies. The available data on benthic invertebrates are from surveys undertaken both by SEPA and by marine biologists commissioned by fish farm operators to meet licence condition requirements on self-monitoring.

To ask the Scottish Executive what the allowable concentration is for sediments of chemicals used in sea lice treatment and what powers are available to the Scottish Environment Protection Agency should this be breached.
Answer
There is a range of allowable concentrations for the various medicines used as sea louse treatments. Some of these are formal Environmental Quality Standards (EQS), others Probable No Effects Concentrations (PNEC). The standards are as set out in the following table:

Should an EQS or a PNEC for sea louse chemical be breached following the use and discharge of the substances to treat sea lice at fish farms, SEPA would take various steps to rectify the situation - for example, through a variation of licence conditions limiting the further release of these substances until residue levels reduced to below those identified safe levels.

To ask the Scottish Executive what the penalty is for non-conformance with the (a) aquaculture industry’s code of good practice and (b) Scottish Environmental Protection Agency's licences for discharge.
Answer
The question of any penalties for non-compliance with the Code of Good Practice for Scottish Finfish Aquaculture is not a matter for the Scottish Government. The code is non-statutory and auditing of compliance with its terms, as appropriate, is a matter for industry.
Non-compliance with the conditions in licences issued by SEPA under the Water Environment (Controlled Activities) (Scotland) Regulations 2011 can lead to a number of steps being taken by SEPA. These can include negotiations with the operator to agree remedial actions, the issue of formal warnings, the serving of Enforcement Notices, undertaking variations of the site licence and, if necessary making reports to the Procurator Fiscal with a view to bringing a prosecution.

To ask the Scottish Executive what investigations (a) have taken place and (b) are planned regarding the potential terrestrial sources of the chemicals identified in the Scottish Environment Protection Agency reports, JT000811_JT and TR110810_JT.
Answer
Prior to publication of the reports, informal investigations took place into other potential sources of the chemicals identified in the reports published by the Scottish Environment Protection Agency (including forestry agriculture and horticulture uses). No plans for further investigations into these possible sources have been finalised at present. However, SEPA is progressing with plans to investigate the results of the surveys further and any future investigations will be planned with a view to providing evidence of the source of any contamination to facilitate further enquiries and enforcement should that be necessary.

To ask the Scottish Executive whether it considers that the aquaculture developments in the areas assessed by the Scottish Environment Protection Agency reports, JT000811_JT and TR110810_JT, comply with the aquaculture industry’s code of good practice.
Answer
The Scottish Government has made no such assessment. The code is non-statutory and auditing of compliance with its terms, as appropriate, is a matter for industry.

To ask the Scottish Executive when it will publish the 2010 data on the occurrence of chemicals used in sea lice treatments in sediments adjacent to marine fish farms.
Answer
The analysis data from samples taken in 2010 and 2011 will be published in the spring or early summer 2012.

To ask the Scottish Executive what evidence it has on the use of unlicensed chemicals to treat sea lice.
Answer
Reports recently published by the Scottish Environment Protection Agency (SEPA) show residues of various chemical substances in sediments. Some, although not all, of these substances are legitimately licensed as sea louse treatments but the nature of sampling in this case means the analytical results are not sufficient to identify the source of those chemicals nor to link these residues to the unlicensed use of the chemicals for the treatment of sea lice.
