Fish assemblages have been extensively studied in the Tabarca Island Marine<br />

Reserve (TIMR) since 1990, using underwater visual census (UVC) as the<br />

main sampling technique. The principal objective has been to study the<br />

temporal and spatial variations <strong>of</strong> fish assemblage at several spatial scales,<br />

from 10s to 1000s metres (Bayle 2002; Forcada 2004; Valle Pérez et al.<br />

2001; Valle Pérez 2001, 2005). Fish assemblages associated with an artificial<br />

reef placed in the TIMR were also studied to evaluate the suitability <strong>of</strong> these<br />

structures to restore <strong>marine</strong> habitats and species (Bayle et al. 1994, 2001;<br />

Bayle & Ramos 2003). Larval fish stages were also studied to describe its<br />

assemblage structure over an annual cycle (Bordehore 2000; Bordehore et al.<br />

2001) and the effect <strong>of</strong> P. oceanica seagrass meadows as habitat on the<br />

vertical distribution <strong>of</strong> ichthyoplankton (Del Pilar Ruso 2004; Del Pilar Ruso &<br />

Bayle 2006). Metallic trace elements were studied in otholits <strong>of</strong> D. vulgaris to<br />

define their suitability as a markers to assess the spillover from MPAs<br />

(Gillanders et al. 2001), and the results showed a very low variability among<br />

different locations along Alicante coast.<br />
