Terms of the fisheries management

The management of fisheries is mainly based on scientific evaluation of the stock state performed by the ICES and the STECF for European stocks, by scientific committees corresponding to each regional organization for fisheries management (RFMO) for stocks they are responsible of.

The evaluation of a state of stocks consists in several steps:

  • First step: Collecting catches data using fishing logbooks and sampling, notably to establish the composition of catches by fish age or size;
  • Second step : Collecting biological data via at sea scientific campaign and sampling on board of fishery vessels or at the fish auction;
  • Third step : The modelling of each stock and the simulation of its evolution depending on several parameters (recruitment, individual growth, natural mortality and mortality when captured)

Fisheries management can be divided in 4 steps which make several actors intervene:

  • Gathering evaluation data (professional fishermen and scientists)
  • Evaluation of stocks (scientists)
  • Creating management rules (the government and professional fishermen)
  • The monitoring of the enhancement and the compliance to the management rules (administration)

Fisheries management can be of different forms.

It may consist in the creation of rules regarding access to waters, often via the creation of specific fishing authorization per areas.

Fisheries management can be a regulation on fishing effort such as restricting the number of vessels in a certain area or limiting the number of catches per vessel. The most known management method is setting TAC and quotas.

Finally, the creation of technical measures is also part of the tool range available to the manager in order to rule the fisheries. Technical measures consist in the creation, for example, of operating rule for fishing gears, minimum fish size or area closure.

All these measures may combine and be part of a management plan. These various fisheries management methods are also used in the « licenses » or « fishing authorizations » delivered by State, the Committees for Fisheries and the OPs.
