Somatic Condition and Reproductive Potential as a Tandem in European Sardine: An Analysis with an Environmental Perspective in the Northern Adriatic (Gulf of Trieste)

The European sardine’s condition is reflected in its reproductive potential, and therefore, status as a fishery resource. These values depend on the stock’s distribution resource availability, which highly determined by environmental characteristics. Sardines from productive Gulf of Trieste (in North Adriatic), located northernmost section most septentrional Mediterranean sub-basin sardine exploitation has traditionally been intensive, were analysed. cycle gonadosomatic index (GSI) studied. Tissue mesenteric fat values, well vacuity (% V), relative (Kn), hepatosomatic (HSI) indices evaluated due to their potential relationships with performance. results suggested opposite patterns between reserves GSI, while Kn showed relationship neither nor stage, led us conclude that it more advisable apply direct lipid project contribution potential. Moreover, females’ was generally better than males, added an advanced gonadal development during spring summer, albeit males females reached spawning season together. GSIs significantly higher active spawning. Furthermore, correlation analyses SST related parameters evaluated, available portion productivity for fish (OPFish), may explain sardines’ chlorophyll concentration.
