Monitoring strategy description
Cephalopods play an important role in the Adriatic marine ecosystems and in commercial fishing (primarily demersal). During MEDITS expeditions in the Adriatic, 32 species of cephalopods were recorded. Most cephalopods in the Adriatic are short-lived organisms whose biomass varies significantly depending on the intensity of recruitment, and it is closely related to hydrographic conditions in the sea (primarily temperature and salinity). Given the fact that cephalopods are an important part of commercial fishing, the intensity of fishing also has a significant impact on biomass. The most important species in the coastal part are Eledone moschata, Loligo vulgaris, Octopus vulgaris and Sepia officinalis. In the deeper parts of the Adriatic, the most common species are Eledone cirrhosa, Illex coindetti, Todarodes eblane. The main strategy of monitoring is to assess the environmental status of the most commercially important cephalopod species that are intensively exploited by fishery fleet in the Adriatic Sea. The assessment will be based on determination of the level of anthropogenic pressure, population density, demographic characteristics of the exploited populations, and distribution of the species in the Adriatic Sea. Monitoring of the main cephalopod species will be conducted through scientific research at sea (MEDITS) and monitoring of commercial demersal fishery through EU framework for the collection and management of fisheries data (DCF). Monitoring sampling scheme and processing of the biological data will be conduct in accordance to the sampling scheme already described for demersal species under Descriptor 3 (Commercial Fish and shellfish).

Gaps and plans
The hydrographic conditions in the Adriatic Sea have seasonal trends and as it was aforementioned, those conditions are closely related to the biomass of short-lived organisms such as cephalopods. In order to collect more detailed information on environmental status of those species additional seasonal scientific surveys should be considered. The current monitoring strategy is going to cover seasonal sampling through monitoring of the commercial fisheries fleet. However, the information collected through commercial fisheries are dependent on methodologies of certain fisheries, specific management measures (season closures, mesh sizes, minimum reference size of species etc.) or socioeconomic factors, and cannot provide representative data on population density trends and distribution of target species.

Programme description
Cephalopods play an important role in the commercial fishing. The majority of data will be collected during scientific and fishery biological research within the MEDITS expedition, whose research area is the entire Croatian territorial sea from the coastline to a depth of 500 meters.
