| Objective | Calculating a stock abundance index for Nephrop prawns in the Grande Vasière mudflat (Bay of Biscay), size and gender structure; spatial distribution of the population by sedimentary unit. Macroscopic observation of stages of sexual maturity in females, sampling of male appendices. Abundance index estimations for related species. Calcified parts were removed to determine the age of species of commercial interest whose stock dynamics are being monitored. Temperature, salinity and depth logs taken. |
