In another thread: A very good point (although I disagree with harvesting whales). The word that catches my eye however is 'sustainable'. This brings me to an alternative way of 'sustainably harvesting' fisheries resources. People hail the Quota Management System [QMS] as the best way to sustainably manage fish stocks, assuming you have an accurate way to assess those fish stocks, and know the fundamental biological data about species life histories and interconnectedness with their environment. Sadly we know too little about their life histories, and almost nothing about trophic interconnectedeness. I would like to see an alternative 'QMS' developed. We know that it is the effort (trawls, dredges, frequency) that damages the environment (sea bed and water column), and removes from the system (ecosystem) huge numbers of bycatch species that are of no commercial value and are discarded. As we pillage the environment, increasing effort to catch fewer fish, we end up doing more damage to it ('Catch Per Unit Effort' [CPUE] decreases, Total Catch may remain the same, but environmental damage increases). Why don't we quota the effort? Example: "The fishing industry is allowed to conduct 'x' trawls within a given area any given year, regardless of CPUE" Comments? How could a system like this be developed? Myopsida?
