Ziel der Reise / Objectives of Cruise:
Bottom trawl survey. Main purpose: Applying swept area method for biomass estimation, population parameters collection, catch per unit effort, CPUA, maturity, stomach content, establishing MSY and TAC (quota) for turbot in Bulgarian Black Sea waters; composition and parameters characterization of by catch species.

\nZooplankton samples were collected with ring net - 36cm.diameter, and 150im mesh size. The species abundance was accomplished according to Dimov's method (Dimov, I., 1959). Individual standard species weights were used for calculations of biomass in milligrams per cubic meter (Petipa, 1959). Samples-9\n | no |
| IFA | Iankova Maria | 18 | stations | B19 Demersal fish |
\nSamples were collected by bottom trawl with parameters: 10x10cm mesh size; length of the mouth: 25m; vertical disclosure of the trawl: 3m; effective part of the mouth: 10-12m.\nAll individuals were measured to the nearest (cm) and weights were measured to the nearest (g) with technical scales; sex of all individuals were determined; otholits for age reading were also collected; stomachs were collected for food composition estimation; All necessary biological indexes and technical data were sys | no |
