Biology & Life cycle: Distribution & Habitat: Norway Lobster; Dublin Prawn; Langoustines Adult body length between 8 and 24 cm. Ovigerous Females (Carry eggs). Mating around July the eggs spawn Aug/Sep & are carried 9 months, Hatching April/ May. Berried Females . Larvae develop in the plankton & only settle on the seabed 6-8 weeks after spawning. Males are generally larger than females. Discontinuous growth due to successive molts (Changing of the shell). Rapid growth when soft. Soft mud =Low density but fast growth. Larger. Sandy mud =High density, slow growth. Smaller. A scavenger & non-selective predator. Diets on North Eastern side of the detritus, crustaceans, molluscs, worms, & others. Atlantic Central & Western Mediterranean regions. Muddy/sandy bottoms. 20 to 800 metres deep. Primarily nocturnal.
Main Behaviour trait affecting fishing: The Burrow is my house Sustainability Norway Lobster lives in small burrows (with 2 or more openings) up to 30cm deep. Trawling (main fishing method) is generally unable to catch burrowed individuals. They emerge from burrows generally to feed & mate. Light plays a major part on thetiming. Higher catches at dusk & dawn suggest it is then it occurs. Jun-Sep = 50%. Females are berried for 9 months & spend most of the time inside their burrows.Therefore they are generally protected from trawlers. Males dominate catches.
Fishing methods, w ork on board and product destination: OTTER TRAWLING. Norway Lobster tailed at sea. Twin & Single. Product destination = SCAMPI The catch being lifted: Only commercially viable fishing method that delivers required volume. Single rig Trawl Twin rig Trawl The catch being sorted: Norway Lobster landed whole. Product destination = EXPORT CREELING. Traps containing bait. Very selective. Delivers low volume but of high importance for high end restaurants.

FACTS/TRENDS: IMPORTANCE: Reduction of: Fishing fleet. The most valuable UK fishery. Crew members. By very far the largest on shellfish. No of Days at sea/effort. Dependency of smaller communities on it, Nephrops catches, since 2007. especially the ones that have the <10m fleet, The % of Nephrops tails landed. that consistently deliver the highest product Increase of: freshness. Seafood consumption Sustainable fishery, MSC on the way. Whole langoustines landed. A species that is highly regarded as one of a Price for the last year. kind, with enormous commercial potential, that delivers on many product tiers. Maximise growth.WHAT IS HAPPENING?: POSSIBLE ACTIONS NEEDED: WHY THE RECENT DECLINE (price is as Extra assessments of Natural Stocks.good as ever): Evaluate benefits of area/month closures. Industry NEEDS stability, we cannot Is MSC a real measure on sustainability? over fish then strangle the supply. Price. Need support from the industry. Expensive to go out to sea for the very New Market avenues. low return...low landings VS fuel prices. More effort needed in research. Are natural stocks worse than More consumer awareness required, especially expected? the UK Broaden offering of different product Closure of large fishing areas in the NE. types. How to maximise the quota uptake.
