# Shellfish
The three types of shellfish species (Cockles, Mussels and Oysters) have different distribution within the Oosterschelde. The cockles are restricted to the intertidal areas. Mussels are cultured at the mussel culture plots. Oysters are cultured at the culture plots and at the wild oyster beds.

*Distribution of shellfish populations in the Oosterschelde. Cockles are restricted to the intertidal areas (khaki). Mussels are cultured at the mussel culture plots (blue) and oysters are present at the culture plots (orange) and the wild oyster beds (green).*
The total biomass of mussels at the culture plots in the Oosterschelde is estimated from the auction data. The cockle biomass is based on the results of the [WOT survey](https://shiny.wur.nl/Schelpdiermonitor_Delta/). The estimation of the wild oyster biomass is based on [Jansen et al. (2019)](https://edepot.wur.nl/504079) at the stock of oysters at the culture plots is calculated from the landings.
