| dc.description.abstract | Black ghost fish is a fish which is good economic value, both in the national
and international scope. Market demand for the black ghost fish high, so it requires
an effort to fulfill consumer demand for the black ghost fish. One of the efforts is to
giving stimulation with thyroxine hormone into the commercial feed which is used
for the growth of the black ghost fish. This research aims to determine the optimum
dose of decent used for the growth and survival of black ghost fish optimally.
Research held in April 2014 to June 2014, is located in the Regional
Technical Implementation Unit of the Department of Agriculture and Marine
Aquaculture Medan City, North Sumatera. The tested fish are black ghost fish size
of 6 cm which is maintained in an aquarium sized 60 cm×40 cm×40 cm by 13 units
arranged randomly. The design which is used was a completely randomized design
(CRD) with doses of 0 mg/kg, 10 mg/kg, 15 mg/kg, 20 mg/kg and 25 mg/kg.
The results showed that the optimum dose which is good for the growth and
survival of black ghost fish is 25 mg/kg, which is 4.36 cm long growing from the
initial length and weight growth of 4.96 g of initial weight. | en_US |
