Objectives

1) Establish a data collection co-ordination group whose function would be to facilitate the process of acquiring the (Boundary Condition and in-loch) data required to validate these and similar models in future.
2)Link an appropriate version of the PML ShellSIM model with the LESV model
3) Assess constraints and advise on application of existing farm-scale and spatially-resolving shellfish models for farm scale (A) management.
4) Complete development of the improved bio-optical model in LESV, using samples and observations already made by FRS
5) Support use of ACExR and LESV models.
6) Extend the physical boundary condition data base and test the ACExR models at a wider range of sites (using the data already collected by FRS and new data)
7) Extend the chemical-biological BC data base and test the LESV models at a wider range of sites (using the data already collected by MLA and new data)
8) Test the ShellSIM-LESV-ACExR combination against observations of mussel growth in at least one sea-loch.

Summary

The proposed research aims to continue work done in SARF 012 to develop modelling tools for the estimation of the capacity to assimilate waste from cage-farmed fish on the zone 'B' or water body scale in Scottish lochs and voes. The ACExR and LESV models will be tested at additional sites. A sub-model for the growth of farmed bivalve molluscs will be added to provide a tool for estimating bivalve carrying capacity on the water body scale and to investigate synergies between shellfish and finfish farming.
