Abstract
The occurrence of Nephrops norvegicus larvae in the western Irish Sea determined by survey cruises during 1969, 1970 and 1971 showed distribution patterns of the Irish coastal population which appeared to be, to some extent, separated from
others adjacent (e.g. S.W. Manx), Vertical distribution showed the greatest numbers at 10-15 fm depth by day, ascending by
approximately 5 fm around dusk; numbers deeper than 20 fm were very small except late in the season when they increased
greatly. Differences between the Irish Sea and Faeroe, north~eastem English and Adriatic waters in larval season and rate
of development were also found.
