59 LINN Each fish stock is assigned numerous properties in a clearly arranged input overlay. In addition to purely basic infor- mation (such as species and sex), para- meters for feeding can be set. We provide characteristic curves for temperature dependency (specific to the fish species), daily requirements, expected feed quo- tients and much more. The daily feed ration can be divided into up to 20 indivi- dual feeds, even repeated feed-free days are possible. The harvest maturity (date for desired tar- get weight) can be calculated on the basis of the current settings, the adjustment of the growth rate then allows fish produc- tion to schedule. Since the water tempe- rature plays a decisive role, a characteris- tic curve with monthly mean values can be used as a basis. All characteristic curves are already included in the software, but can be individually adapted to the condi- tions of your own system. The fish stock can be afflicted with un- foreseen losses, so the stock numbe- ris automatically reduced once a day. Stocking densities are determined, ex- ceeding limits generates corresponding warnings. The growth of the fish requires an adjust- ment to take account of the feed pellet size. FishFarmer can do this for you ea- sily . It is possible to store feeding plans, which assign a mix of 2 feed types to a fish weight. In the transition phases, for example, Feed 1 is reduced from 100 % to 67 % at 100 g fish weight and Feed 2 then comprises the remaining 33 %. A further reduction of Feed 1 to 33%would then be conceivable from 110g onwards, in order to finally feed only Feed 2 from 120g on- wards. This allows the fish time to adapt to the new size. All Automated data inputs and where necessary, manual inputs are brought together in a report. Using all data inputs FishFarmer can then make evaluations. The actual feed quotient calculated in this way can then provide an optimised feed supply for the next generation of fish. However, meaningful results are only possible if the actual fish weight in the tank is determined regularly, compared and entered as a correction in the pro- gram. Another function is growth plan- ning. Here the growth of the fish can be calculated with different defaults. The de- termined optimum growth factor is then set in the feeding overlay and provides precisely produced fish with the desired weight. growth planning ADVANTAGES: l Developed frommany years of practical experience! l Integrated online help to support the user l German and English version can be interchanged l A 30-day demo version is available as a free download
