World Aquaculture 27 the fish flesh quality by increasing the content of omega-3 fatty acids and other relevant compounds that have substantial importance for the prevention of cardiovascular and other diseases. The output of the program will be technology for production of fish, mainly carp flesh with better dietary effects for human health. 2. Caviar production technology by means of breeding allfemale populations of sturgeon species in fish ponds and recirculation systems, while maintaining the existing genetic diversity of current farmed species (Figure 17). The output of the program will be production technology for rapid growth of sturgeon populations with higher survival rates in recirculation systems. The subject will also be the production of genetically characterized parental populations of sturgeons with the determination of the molecular-genetic profile of caviar from producers. 3. Innovation of intensive production methods of commercial and game fish species focused on the innovation of intensive production of commercial fish species and production of quality fish intended for restocking non-aquaculture waters. The output will be technological procedures ensuring fast-growing populations of commercial fish species. For the production of fish stocked in open waters, the breeding technology that uses modern molecular methods will ensure high bio-genetic quality of fish. 4. Development and innovation of continuous water quality monitoring systems utilizing fish and crayfish as bio-indicators and innovative procedures within the management of reservoirs. The main objective of this project is the development and innovation in systems of continuous monitoring of water quality using fish and crayfish (Fig. 10) as bio-indicators with an emphasis on their maximum capability, reliability, low attendant demands and efficiency. The output of the program will be suggestions of technological quality and safety control of drinking and supply water with the use of fish and crayfish as key bioindicators and other sophisticated control mechanisms. 5. Innovation in monitoring the occurrence and impacts of extraneous substances in the environment aimed at innovation and efficiency of procedures focused on detection of compounds that contaminate the environment and also the evaluation of the effects of ´new´ contaminants on water organisms. 6. Creation and utilization of systematic knowledge basis for development of experimental techniques directed to the implementation of the latest trends in seafood processing in terms of their analysis and evaluation including development of new standards. Current Constraints and Opportunities Environmental regulations severely constrain opportunities for some intensive and even semi-intensive culture systems. For instance, fertilizers and feeds cannot be used in fish ponds without special permission. The majority of ponds are heavily silted, with soil particles deposited in thick sediments that considerably reduces the pond production capacity and contributes to overgrowth of water (Continued on page 68) Fig. 17.
