The Growth Of Motan (Thynnicthys Thynnoides) With Different Rearing And Stocking

Abstract

The research was aimed to determined the growth and survival rate of Motan fish (Thynnicthys thynnoides) were rearing in cages with different stockings and locations. The treatments stocking used 40, 50, and 60 fishs/cage with a size 1 x 1 x 1 m. It was conducted on May to October 2010, while the located of rearing was in Kampar river and ponds of Fisheries and Marine Science Faculty of Riau University. Results of this studiy was showed that the best growth was rearing in the cage with stocking 50 fishs/cage on Kampar river, the growth in the absolute weight of 8,61 grams, the growth of the absolute length of 2,34 cm, the daily weight growth rate of 0,5445 %, the daily length growth rate of 0,1750 % and the survival rate 100 %.The research was aimed to determined the growth and survival rate of Motan fish (Thynnicthys thynnoides) were rearing in cages with different stockings and locations.
