| Summary: | The Loch Linnhe Biological Sampling data resource contains both biological and sampling information for 2011-2013. This is linked to the physical data collected at the same time which is available upon request from MSS. During the 2011, 2012 and 2013 field seasons sea lice were sampled using plankton trawls at 30 trawling stations sampling for planktonic phase lice (following Penston et al. 2008, and described in Salama et al. 2017), and 9 sentinel cage fish (as used by Pert et al. 2014) sites to sample settled stage lice. This data can be used to provide an assessment of the validity of modelled outputs.?? The “plankton station information” contains all the technical information required to describe each individual station sampled. The “plankton sampling information” data set includes the counts of pelagic stages of lice collected in the water column at each individual haul. The “plankton data summary” summarises the sampling information by season. The “sentinel cage station information” contains all the technical information required to describe each individual cage location. The “sentinel cage sampling information” contains all of the counts of lice present on fish. Product usage: The recommended usage of these data is for sea lice dispersal model validation for the time periods included in the products. References Penston, M. J., Millar, C.
