CIESM Workshop Series, n°12:

Fishing down the Mediterranean food webs?
Kerkyra, Greece, 26-30 July 2000, 99 p. (190 ref.)

The development of "trophic level" reference points is an important issue for fisheries research in the Mediterranean where other "traditional" reference points are hard to establish. The meeting, which brought together prominent and younger scientists active in this area, allowed to :

  • identify gaps in and assess the potential use of trophic levels for the identification of fisheries status;
  • assess the usefulness of trophic levels as reference points, and
  • establish directions for future ecological and fisheries research in relation to the above aspects.
  • This volume, fully illustrated and rich in references, is available in print from our on-line bookstore.
