We need a synergy strategy (example improved and advanced technology in fish farming operations ) for this to happen because human population is growing geometrically as against the arithmetic growth pattern of food (fish) source/production.
fish consumption is higher than global average in high income countries and lower in low income countries
production could be increased if overfishing was stopped and more adult fish left in the water to reproduce with management according to the ecosystem approach, incl. harvesting less than can regrow and fishing prey species less than predators to account for interaction in the ecosystem;
Fishing should be high in the food web, fish farming low in the food web for best results
