Changes in Life History Traits of Small Pelagic Fish in the Western Mediterranean Sea Open
Small pelagic fish (SPF) in the western Mediterranean Sea are key elements of the marine food web and are important in terms of biomass and fisheries catches. Significant declines in biomass, landings, and changes in the age/size structure…

Zooplankton Biomass Depletion Event Reveals the Importance of Small Pelagic Fish Top-Down Control in the Western Mediterranean Coastal Waters Open
The influence of hydrochemistry and trophic conditions on the coastal zooplankton community’s biomass and metabolic activities was investigated along the Spanish Mediterranean coastal waters, from Algeciras Bay to Barcelona, from autumn 20…

Variability of oceanographic and meteorological conditions in the northern Alboran Sea at seasonal, inter‐annual and long‐term time scales and their influence on sardine (<i>Sardina pilchardus</i> Walbaum 1792) landings Open
Time series of European sardine ( Sardina pilchardus ) landings from 1962 and environmental variables from 1978 in the northern Alboran Sea are analysed. European sardine spawns in the northern Alboran Sea from mid‐autumn to late winter at…

Report on stock status and reference points Open
The status of the sardine and anchovy stocks in GSA 06 and GSA 07 were investigated using statistical catch-at-age (a4a) and two-stage biomass models. Life-history parameters of both species were reviewed and new estimates of the von Berta…

Report on historical reproductive pattern : Size and age at first maturity and reproductive period Open
Long term trends in the variation of reproduction parameters can be indicative of a change in the life-history traits of the species and could have consequences for survival (i.e. natural mortality) and condition, and ultimately affect rec…

Report on body condition Open
Body condition is a proxy of the quantity of energy stored and is dependent on food supply and energy allocation strategies. Population reproductive potential, growth and survival (i.e. natural mortality) can be affected by body condition.…

Report on gonadosomatic index, size at firs maturity and reproductive parameters Open
European anchovy (Engraulis encrasicolus) and European sardine (Sardina pilchardus) have short lifespan and produce many eggs per body mass. Both species usually spawn at 1 year old. In order to understand population dynamics in small pela…

Report on age, growth and age-composition Open
In order to manage small pelagic fish species, such as European anchovy (Engraulis encrasicolus) and European sardine (Sardina pilchardus), and enable to implement properly stock assessment analysis, it is essential to study the growth and…
