Management AdviceManagement considerations
There are no management objectives for this stock and there is no TAC. Almost all catches are taken by Spanish and Portuguese purse-seiners in a directed human consumption fishery. The stock is managed by Portugal and through minimum landing size, maximum daily catch, days fishing limitations, and closed areas.
Sardine is distributed in the Iberian region, to the north in Subareas VII and VIII and in the North Sea, and to the south on the Moroccan shelf. The information presented here assumes that sardine in Divisions VIIIc and IXa is a unit stock, based on biological characteristics. However, some movement of fish between Divisions VIIIb and VIIIc is known to occur. The effect of this movement is uncertain but is presently considered to have little influence on the estimation of the stock in the assessed area (Divisions VIIIc and IXa).
Short-term predictions indicate a moderate decline (-14%) in SSB in 2010 from the SSB in 2008 at the assumed fishing mortality level, providing the 2008 recruitment is confirmed to be average and no strong recruitment occurs in 2009. Therefore, the catch in 2010 should be reduced. In the past, extended periods of successive low recruitments have been associated with periods of minimum stock size, most recently in the late 1990s, causing a negative impact in the Spanish fisheries.
A long-term plan would result in an improved management of this stock. Such a plan should take into account the spatial distribution of the stock. Management aiming at stability of catches may be more consistent with the objectives of stakeholders. A long-term management plan would be useful if stability of catches is desired. Such a strategy should be sufficiently flexible with respect to catch limitation to protect the stock under periods of poor recruitment, but also avoid unnecessary fluctuations in the catches when the stock biomass is higher.
