#Angling - Inland Fisheries Ireland (IFI) is currently carrying out a fish stock survey on Lough Derg to assess the current status of the fish populations in the lake.

The survey began on Monday 13 June and continues till Friday 1 July. It involves the netting of over 200 sites throughout Lough Derg and Parteen reservoir.

Four different types of survey nets are being used. Many of these survey nets are being set on the lake bed but a small proportion are being set as floating survey nets on the surface. A hydroacoustic survey of the deeper parts of the lake is also being undertaken.

The fisheries research survey will be conducted by IFI under the supervision of Inland fisheries research staff and will include a total of five boat crews with one of these working at night.

The survey will provide a range of information on the fish stocks in the lake, such as size distributions of fish captured, age and growth information for all species, diet of selected species, and catch per unit effort (CPUEs) for each fish species.

It will also provide information on the status of pollan, a rare and endangered fish species. In addition, samples for genetic analyses of brown trout and pike and other species will be taken.

The survey crews will be very visible on Lough Derg over the next few weeks and all sets of nets will be marked with distinctive buoys labelled ‘IFI Survey’.

Any anglers or other lake users are asked to be vigilant if out and about on the lake over the next few weeks and to avoid snagging in the nets.

We've got a favour to ask

More people are reading Afloat.ie than ever thanks to the power of the internet but we're in stormy seas because advertising revenues across the media are falling fast. Unlike many news sites, we haven’t put up a paywall because we want to keep our marine journalism open.

Afloat.ie is Ireland's only full–time marine journalism team and it takes time, money and hard work to produce our content.

So you can see why we need to ask for your help.
