Description: 1982: Five surveys of samples were carried out to estimate the spawning stock biomass of the western Irish Sea nephrops. Plankton samples were sorted and all fish eggs and larvae were identified to species level where possible. Nephrops (Nephrops norvegicus) larvae were also sorted and staged into 4 developmental stages. Seasonal production estimates and mortality rates have been calculated for nephrops. Temperature and salinity "V" shape profiles are available at each sampling portion. Surface salinity values are available from bottle samples and nutrient data (nitrate, nitrite, phosphate and silicate) are available from each sampling position. 1985: Four surveys of 70-90 stations were carried out to estimate the spawning stock biomass of Western Irish Sea nephrops. The analysis was as described for 1982. Environmental parameters were also as described for 1982.
