The possibility to protect oneself against financial losses through an insurance policy is not new and is practised in almost every area of life. Many aquaculture companies choose to do without this risk insurance however because they feel the requirements are too high, the procedure too complicated or the premiums too expensive. But taking out insurance in the aquaculture sector can definitely be worthwhile and should be a part of risk management.
Chapter Five: Running a recirculation system
Moving from traditional fish farming to recirculation significantly changes the daily routines and skills necessary for managing the farm. The fish farmer has now become a manager of both fish and water, and the task of managing the water and maintaining its quality has become just as important, if not more so, than the job of looking after the fish.
Chapter Six: Waste water treatment
Farming fish in a recirculation system where the water is constantly reused does not make the waste from the fish production disappear. Dirt or excretions from the fish still have to end somewhere. The biological processes in the system will to a certain extent reduce the amount of organic compounds, because of simple biological degradation or mineralisation within the system. However, a significant load of organic sludge from the farm will still have to be dealt with.
Chapter 7: Disease
There are many examples of recirculation systems operating without any disease problems at all. In fact, it is possible to isolate a recirculation fish farm completely from unwanted fish pathogens. Most important is to make sure that eggs or fish stocked in the facility are absolutely disease free and preferably from a certified disease free strain. Make sure that the water used is disease free or sterilised before going into the system; it is far better to use water from a borehole, a well, or a similar source than to use water coming directly from the sea, river or lake. Also, make sure that no one entering the farm is bringing in any diseases, whether they are visitors or staff.
Gümüşdoğa A.S was established by Mr. Halil Milas in 1995 with the first facility of seabass and seabream farms in the Bodrum area of Turkey. The farm production capacity was initially 80 tonnes per year, a figure that increased continuously to the current 10,000 tonnes per year.
Against a backdrop of global economic uncertainty and food price volatility demand for fish and fishery products as a source of high-quality, affordable animal protein is rising steadily. From 1990 to 2008, per capita world fish consumption increased by 27 percent (from 14 kg in 1990 to 17 kg in 2008) despite a 26 percent growth in world population during this period. This increase in fish consumption is mainly attributed to aquaculture growth.
The GlobalG.A.P. Aquaculture Standard is a voluntary standard developed by a private sector body that sets criteria for legal compliance, food safety, workers’ welfare, animal welfare, and environmental and ecological care.
Salmon lice are probably one of the biggest threats to salmon farming at the moment. The available control methods are often not sufficient to effectively reduce lice infestation. In Norway radical measures are sometimes even considered, such as slaughtering whole salmon stocks or concerted action to leave farms unstocked. But might it be possible to solve the salmon louse problem biologically using “cleaner fish”?
Although fishmeal production in the two main producer countries Peru and Chile was 40% higher in 2011 than in the previous year this increase brought little relief to the situation on the aquafeed market. Fishmeal prices fell slightly but are still at a high level. And they will probably remain more or less the same, particularly since already in spring 2012 there were signs that raw materials availability for the fishmeal industry would probably be lower again this year.
