    Based on the discussion at EMM 2016 we here present challenges, results and potential of using a net cable to inform crew and scientists on trawl performance. Some results from ongoing tests demonstrate its potential in allowing observations of trawl in relation to krill distribution and behaviour, including real time imaging of krill and predator behaviour in relation to fishing gear during experiments. Due to the vessel-and gear differences of Saga Sea and Antarctic Sea presently using the continuous trawling method they require different solutions to operate an instrument cable. This paper therefore clarifies alternative approaches and suggests for Antarctic Sea the option of attaching the net cable to other operational cables of the trawl system thus avoiding a free third cable.
