Domestication of Motan (Thynnichthys thynnoides Blkr) in Cages with Different Types of Fish Meal
ABSTRACT: The research was
conducted from 18 March until 16 May 2011 in Research Station of Fisheries and
Marine Science Riau University. The objective of the research was to find out
the suitable fish meal as long as domestication activities on the growth and
survival rates of Thynnichthys thynnoides Blkr. The fish meal used in this
research was shrimp pellet, snail meat, chicken intestines and vegetables. Fish
were reared in the 0.5 m x 0.5 m x 0.5 cages for 60 days with stocking density
of 25 fish/m3 cage. The method used in this research was completed randomized
design method with four treatments and three replications. Results showed that
the best absolute growth rate of 19.02 grams, daily growth rates of 2.304 %
were obtained in the treatment of dried pellet combining with vegetables, while
the worst performance was obtained in treatment of dried pellet combining with
vegetables with growth rate of 12.39 grams and daily growth rate of 2.134 %
respectively. Water quality parameters recorded in the research were water
temperature, pH, dissolved oxygen and NH3 of 27 – 30 oC; 6 – 7; 4 – 4.6 ppm;
0.006 – 0.024 ppm respectively.
