1.-Difference between discards and bycatch.
By-catches are the portion of the catch that is not targeted. Organisms are considered as by-catches when:
- the organisms caught have no commercial value (most invertebrate species, some fishes species, birds, marine mammals, turtles…);
- the organisms caught belong to protected species whose fisheries are not allowed;
- the organisms caught have commercial value but their size is below legal limits or the allocated fishing quota has already been reached.
- the organisms caught have commercial value, their size respects legal limits and they correspond to the allocated fishing quota, but they do not belong to the species originally targeted by the concerned fisheries.
Discards are defined by the FAO as the portion of the catch that is thrown away at sea. The reasons for this practice are various:
- the organisms caught have no commercial value (most invertebrate species, some fishes species, birds, marine mammals, turtles…);
- the organisms caught belong to protected species whose fisheries are not allowed;
- the organisms caught have commercial value but their size is below legal limits or the allocated fishing quota has already been reached.
-the organisms caught have commercial value but this is less than that of other specimens caught. This phenomenon is known as “high grading”, in which the haul is sorted to keep the most economically interesting specimens.
3.- What is the framework proposed by Oceana for the implementation of a discard ban?
| First transitory period 1 to 2 years | Second transitory period Several years | Routine enforcement period | |
| Legal size specimens of commercial species | Yes | Yes | Yes |
| Juveniles or undersized specimens of commercial species | Yes | Yes, unless they have a chance of survival | Yes, unless they have a chance of survival |
| Specimens of non commercial species | Yes | Yes, unless they have a chance of survival | Yes, unless they have a chance of survival |
| Specimens of threatened species | Yes, unless they have a chance of survival | Yes, unless they have a chance of survival | Yes, unless they have a chance of survival |
| Specimens of protected species | Yes, unless they have a chance of survival | Yes, unless they have a chance of survival | Yes, unless they have a chance of survival |
| Offal | Yes | Yes | Yes |
| Discards rate | Current | Progressively reduced to minimum | Minimum |
| Marketing of previously discarded organisms (except protected species) | Yes | Yes but progressively reduced | No |
