The development of marine fishing in Montenegro during the 1945-1990 period was insignificant. However, since 1992/93 there has been a rapid increase in a number of ships, so in the season 1997/98 there were 196 registered vessels intended to be used for professional or supplementary fishing. During the last decade or so, there was a period of intensive extraction of trawling resources. There is no doubt that such an activity led to the disturbance of the natural state and the decrease of fish population numbers in the sea. Catch calculated by one hour of trawling decreased from 60 to 20 kg/h. The estimated biomass was half of the similar estimate in 1973 (1,700 tons against 3,400 tons). There data were also used to estimate the biological Maximum Sustainable Yield (MSY) of these resources, which is 602 tons per year, and the optimum fishing effort of 1,190 days per year. First echo-probing in 2002 was used to estimate the biomass of small blue fish to 136,119 tons, including 90,383 tons of anchovies, 30,760 tons of sardines and 14,970 tons of other pelagic species. The initial MSY is 30,910 tons of anchovies and 9,721 tons of sardines. Questionnaires given to fishermen and the rough statistics show that coastal fishing brings annually a yield of 1,200 tons of quality species of fish, crustaceans and cephalopods. Keeping score of catch in marine fishing is still one of the greatest problems at the Montenegrin coast.
