Sažetak
The global increase in fish consumption tallies with trends in food consumption in general. Following this trend the global fish production has grown impressively and it is believed that the increasing trend of animal protein demand will continue in both developing and developed countries. Over 90% of fish products on the international market are traded in the processed form. Fish processing industry is one of the most important industrial sectors in Croatia. Despite this, effective regulations regarding emission limit values for wastewater (NN 087/2010) do not specify values for fish processing industry. Moreover, monitoring reports from Croatian fish processing plants suggest that wastewaters have significantly high concentrations of chlorides and very high concentration of biological and chemical oxygen demand. For this reason it is necessary to perform detailed study in order to establish specific effluent values for different parameters, considering effective emission standards set by EU Directives (76/464/EEC, 91/271/EEC and 2000/60/EC) and international emission guidelines for the management of wastewaters from the fish processing plants. Fish processing plants are situated on islands, in coastal and hinterland region including sensitive water protected areas, which requires specific solutions for each one. This paper reviews this problem and suggests its possible solution through microzonation and elaboration of specific studies for every single area, in order to consider all peculiarities of different plant locations. Helping the fish processing facilities to meet the environmental management objectives for sustainable development and good status of wastewater, values for some parameters are suggested as suitable limits to be considered for the complementation of the regulations, taking into account the location and wastewater discharges in urban wastewater treatment plants, specific discharge recipients and receiving local water bodies.
