Mass-balanced Ecopath model integrating ecosystem stressors and fisheries bycatch. Network analysis evaluates impacts of fisheries and red tide events on species. Meta-analysis of diet composition filled critical gaps in predator-prey linkages. Higher connectivity (amongst groups) and increased omnivory compared to past models. Reveals detrimental effects of red tides on sharks, skates and rays, and fishes.
