LEDding the Way?

Researchers at Bangor University appear to have shown that, at least in deeper, darker waters, attaching LED lights to 'escape hatches' in trawler nets (such as those used for scallops) can significantly reduce the 'by-catch' (https://www.theguardian.com/environment/2020/may/01/led-lights-halve-unwanted-fish-in-nets-research-finds). The by-catch are unwanted species that one does not intend to capture and, without the facility for escape, end up being captured, killed and discarded. This seems an excellent and relatively cheap means of limiting some of the more destructive consequences of this type of fishing.
