Scientists at Bangor University, working with the Welsh Fishermen's Association Natural Resources Wales and the Welsh Government, have published their findings from what they say is the world's biggest ever fishing impact study.
They chose twelve sites in Cardigan Bay where scallop fishing was halted in 2009.
The sites were fished at different intensities and compared to four areas which were left unfished. The results suggest the area can sustain a certain level of fishing.
The study could open the door for fishing to resume once a sustainable level is decided.
Scientists at Bangor University are working to maximise the efficiency of tidal and wave energy generating equipment.
They say computer modelling at the SEACAMS programme accurately predicts tidal currents, wave heights and other important measurements through the water column.
That helps identify the best sites for energy schemes.
They say one project is a 10MW tidal energy converter planned for The Skerries off the North West coast of Anglesey.
A teaching technique that claims to help children relax and perform better at school has been developed by Bangor University. The Mindfulness techniques as they're known, are already being used at a number of schools including one in Colwyn Bay. Kevin Ashford went to see it in action.
The Vice Chancellor of Bangor University, Professor John Hughes, told the Assembly's Finance committee that Welsh universities are 'not in a position to invest' in the way that competitors elsewhere in the UK are.
He said that's making it difficult to attract students from across the UK and from overseas.
The Vice Chancellor of Bangor University has told Assembly Members that universities in Wales are struggling to attract students from the rest of the UK and overseas.
John Hughes told the Finance Committee that institutions here 'are not in a position to invest' in the sort of facilities students who are now paying their own fees expect.
He said that's 'limited' the ability of Welsh universities to recruit students, something which they're 'already seeing in the figures.' The Finance Committee is looking into the impact of the Welsh Government's decision to subsidise the bulk of students' tuition fees.
