For Stock abundance, the large variability in time and space is mostly attributable to environmental factors.

Echosurvey
Data

The annual echosurvey was performed in the summer season 2006 covering the western part of GSA 18. Pelagic biomass estimates, as a whole and per anchovies and sardines, were analyzed.
Results

In this area there was an increase in biomass in the last year. Trends of the western GSA 18 (from Vieste to Brindisi, historical surveys since 1987) show an abundance level similar to that of the years 1997-2002 for total pelagic biomass after the fall of the years 2003-05; this result is mainly due to the anchovy stock that has come back to the abundance level of 5-10 years ago.

The results of the studies of small pelagic populations derived from the historical surveys in the western Adriatic Sea show that these populations are affected by large variability in time and space. This variability is mostly due to environmental factors and this is why an effort is currently in progress to find possible relations between abundance estimates and oceanographic parameters. Even if anchovy (both in Northern and Southern Adriatic) and sprat stock (in Northern Adriatic) showed good levels of abundance in 2006 survey they have just recovered from a previous worse condition; moreover sardine stock still shows a low level of abundance that is going on with continuity since 1998.


Sci Advice

For management considerations
  • It is reasonable not to increase the actual level of fishing effort on small pelagic fish
  • SCSA endorsed the WG management advice and recommendations on sardine (Sardina pilchardus) in GSA18.


For research
Fishery data should be collected
Management
 
Advice

Scientific advices for management consideration formulated by SCSA have been adopted by SAC.
