This upward trend would follow a number of factors, in which are mentioned the decline in production volume of cultured tilapia and higher operating costs for producers.
The lower production of tilapia is one of the consequences of the cold wave that hit the southern China region from late 2009 through the first quarter of 2010. Low temperatures caused the deaths of many tilapia fingerlings, with mortality rates being reported in some areas of up to 50 per cent.
Some estimate that the production of tilapia in the country could decrease between 20 per cent and 30 per cent.
Another factor that is affecting prices is the increased cost of feed.
The price of fish meal and maize increased significantly in the last year and these hikes, coupled with cost increases in the logistics sector, impact on operating costs for tilapia producers.
