An Automatic Feeder with Two Different Control Systems for Intensive Mirror Carp Production

An Automatic Feeder with Two Different Control Systems for Intensive Mirror Carp Production Feeding management provides the producer with a possibility to overcome limited feeding that may exhibit aggressive behavior during feeding due to limited feed availability resulting in carps that do not reach maximal growth.

Abstract

Feeding management provides the producer with a possibility to overcome limited feeding that may exhibit aggressive behavior during feeding due to limited feed availability resulting in carps that do not reach maximal growth. Overfeeding results in feed waste, poor water quality, lower economic profit and additional environmental pollution. An automatic feeder was constructed and evaluated to provide predetermined amounts of food to four fish tanks (9.5m diameter) had 7000 Carps. Growth methodology optimized carp production in the tanks which are grouped in four, three tanks worked as rearing tanks and the fourth as nursing tank. These big tanks required a better of food distribution so three points of the tank were selected as feeding spots: two aside the edge of tank wall and another close to the center. Each point or wireless controlled gate provided the necessary food, giving more chance to the fishes to obtain their provisions without competition. The system uses a hopper which is capable of feeding the four tanks during a week, and the precision of the hopper was relied on a weighting mechanism. Two ways were used to control food provisions in this study. An opened control system based on the ATM89c51 microcontroller controlled the exact dosing based on the tank rquirements according to the carp cycle and the other closed loop control system was determined by the conditions of water temperature, fish age, body weight and the amount of oxygen consumed. The amount of oxygen consumed by carps was the best parameter knowing fish metabolism and growth that the feeder can rely on its controlling meals provisions. The results showed minimal differences in growth (P<0.05) between treatments, a food saving of 25.337% (i.e. 3495.5 kg), and lower water pollution (reduced water dissolved solids and ammonium components) compared with the first automatic feeder.
