Review of long-therm changes in trammel bottom ste catches, crustacean, cephalopoda and fish communities along the Eastern Adriatic (Croatian) coastal area

State and changes in the coastal crustacean, cephalopoda, and fish communities are investigated from 1960. Changes in target communities were manifested as: (i) decline in catches per unit efort (CPUE) ; it was during investigated period along the Dalmatian area between 62.3 percent on Kornati Island, 69.4 percent in the Palagruža Island area, and 24.6 percent in the southern Adriatic ; (ii) increase, on the one hand, in the CPUE of fish family Scorpaenidae as well as fish species Scorpaena porcus and Symphodus tinca and crustacean Maja crispata, and on the other hand CPUE decline of fish family Labridae and Serranidae as well as fishes Mullus spp. and cephalopod species Octopus vulgaris ; (iii) changes in the length frequency distribution of dominant species in the catches, that is Scorpaena porcus, Symphodus tinca and Mullus surmuletus. The changes are primarily due to intensive fishing sctivities in the populations and effect inerspecific and intraspecific relations in them.
