This research identified that the Northern Ireland (NI) Nephrops fleet segments using demersal trawlers (DTS) with vessel lengths (VL) up to 24 meters (i.e. NIDTSVL0010, NIDTSVL1012, NIDTSVL1218 and NIDTSVL1824), are sustainable. Therefore, this study concludes that overall, the Northern Ireland Nephrops fleet segments are making profit in the short term while fishing from stocks that have not been depleted.
