First suggested step to this may be to better break down and understand who is who in the ‘seafood industry’.
Aquaculture and fishing? Fish and shrimp? Sustainable resource building or controlled natural resource exploitation?
As for human gender in shrimp farming the industry has created millions of jobs for women in the processing, post farmed shrimp harvest side. Industry is pretty gender equal in labor and, also, consider that all products getting into mature developed markets are subject to base level import regulatory labor laws (all rights under ILO) with appropriate certifications or, surely, would not enter under basic trade standards.
