Abstract:

This is an Ecopath with Ecosim model of the West Florida Shelf. It is based on a model constructed by Mahmoudi (unpublished data) (see Okey et al. 2004 for an application) and later modified Gray et al. 2013 to incorporate additional exploited and non-exploited species and life stages known to be sensitive to harmful algal blooms (HABs). To incorporate HABs an additional (pseudo) fishing fleet is added into the model to provide a red tide mortality driver on adult fish and invertebrates. Biomass caught by this fleet is immediately cycled into the detritus pool, and thus nutrients from killed fish are made available to detritivores and the bacterial decomposition process. Included in the model are forcing functions to drive historical fishing and HABs from 1980 to 2009. NMFS (2013) was used to force fishing effort. J. Walter (unpublished data, SEFSC) provided a red tide composite series that is used as a driver of the red tide mortality (entered as an effort driver in Ecosim). The series also includes cell count information from FWRI. See Gray et al. 2013 for more information on model and time series development. This model was used in working papers for SEDAR 33 (Gray et al. 2013) and SEDAR 42 (Sagarese et al. 2014) benchmark assessments. Gray, A., Ainsworth, C., Chagaris, D. and Mahmoudi, B., 2013.

Purpose:

This is an ecosystem model for use in harmful algal bloom simulations. The goal of this research is to develop high-resolution models to interpolate oil/dispersant impacts on various trophic levels within the Gulf ecosystem.
