Inside the narrows between Greencastle and Magilligan Point, the Lough is comparatively shallow with depths seldom exceeding 18 metres at low tide.
There is some boat fishing west of McKinneys Bank on the slope running from 10 metres at the Saltpans Buoy down to 18 metres opposite Moville. Bottom fishing over a mixture of sand, shingle and mud will yield dogfish, ray, flounder, dab and occasional plaice.
Some anglers tackle tope from small boats and many more enjoy fishing for other species around the rocky Inishowen coast and within the more sheltered Lough Foyle. There are slipways at Malin, Glengad, Bunnagee, Moville and Greencastle. An increasing number of anglers are fishing with a fly at sea, mainly for mackerel, pollack and garfish.
Small boats can be launched from the slipway beside the pier at Bunagee for fishing the inshore waters between Glengad Head and Dunmore Head where red gurnard to over specimen size, plaice, ray, turbot, john dory, codling and whiting have been recorded - up to twenty species can be expected in a day. The slipway is viable for launch and retrieval on all stages of the tide with the exception of extreme low tide on springs.
Another notable feature of the area is the first class tope fishing which is available from mid-June to mid-September. In recent years catches of up to 30 fish a day have been recorded with the best fish weighing almost 23kg.
Many anglers enjoy fishing within the estuary of Lough Foyle and off Benone beach. There is some boat fishing west of McKinneys Bank on the slope running from 10 metres at the Saltpans Buoy down to 18 metres opposite Moville. There are slipways at Culmore. An increasing number of anglers are also fishing with a fly in the lough, mainly for bass, mullet and mackerel.
In summer, mackerel shoals enter the Lough and during these periods tope will occasionally be found there. Fishing is usually carried out from an anchored boat, but caution should be exercised at all times as shipping has right of way in the buoyed channel.
