Cold-water fish farming is an important part of China's aquaculture industry. To promote the development of the cold-water aquaculture sector, the China Aquatic Products Processing and Marketing Alliance (CAPPMA), Heilongjiang River Fisheries Research Institute (HRFRI) and Aller Aqua recently hosted the 2nd International Cold-Water Fish Aquaculture Technology Seminar in Qingdao, Shandong Province, China.
Participant numbers reached no less than 280 and was comprised of foreign experts and companies, Chinese fishery authorities and major cold-water fish companies (breeding, feed, processing), scientific research institutes, colleges and universities, and cooking, e-commerce, purchasing and media representatives. The event focused on cold-water fish farming, fish nutrition, disease prevention and industrialization. Specific production challenges and potential solutions within farming systems, equipment and recirculated aquaculture systems (RAS) were discussed. Also, the reaction of Chinese salmon and sturgeon industries to the complex situation of international market competition and perception bias of the domestic market was discussed.
Robert Tillner, product manager at Aller Aqua Group, introduced the recently launched feed, PowerRAS, developed by Aller Aqua for high efficiency RAS. He explained how the feed has evolved through years of research on traditional feed combined with the water quality requirements and pollutant discharge characteristics of RAS.
Jacek Juchniewicz, Aller Aqua Polska Sp.zo.o. CEO, introduced Polish trout farming, based on his extensive experience in farm management and RAS. Northern Poland has good water quality, low temperature and few hot periods. It is suitable for rainbow trout and the consumer market is huge. However, many factors need to be considered. These factors, as well as advantages and disadvantages of RAS for trout production, were discussed.
The agenda was also comprised of topics such as applied research, intelligent feeding, processing and consumer trends, ecological culture, trout farming, sturgeon breeding, disease prevention, among others.
The next International Cold-Water Fish seminar will be held in 2021.
