Maybe this will not happen again in European waters

Worst than any fish that is killed to eat,
is the fish killed and thrown out without use neither control.
What a waste!

The new, reformed Common Fisheries Policy says:
Discarding, that is the practice of throwing unwanted fish overboard, is estimated at 23% of total catches (substantially more in some fisheries!). 
This unacceptable practice will be phased out with a precise timeline for implementation (progressively between 2015 and 2019) and in combination with some flanking measures.
Fishermen will be obliged to land all the commercial species that they catch. 
Under-sized fish can generally not be sold for human consumption. 
Member States have to make sure that their fishing vessels are equipped to ensure full documentation of all fishing and processing activities so as to monitor compliance with the obligation to land all catches. 
This ban will lead to more reliable data on fish stocks, support better management and improve resource efficiency. 
It is also an incentive for fishermen to avoid unwanted catches by means of technical solutions such as more selective fishing gear.

Portuguese NGOs have met with the government to discuss these issues and understand how it gone be in the future.
Very good job!
