Consider the following statements regarding aquaculture practices and ecological resilience: Statement I: Reliance on a single aquaculture species increases system-wide vulnerability because pathogens can spread rapidly in genetically uniform populations raised under intensive monoculture conditions. Statement II: Indigenous prawn species such as Penaeus indicus and Penaeus monodon are less viable for brackish-water aquaculture as they lack broad salinity tolerance, unlike exotic species such as Litopenaeus vannamei. Statement III: Integrated Multi-Trophic Aquaculture (IMTA) primarily prevents epidemic disease outbreaks by ensuring that pathogens are neutralised through trophic-level interactions among different cultured species. Which one of the following is correct in respect of the above statements?
