Optimization of protein level of feed for Tor Sp. Fry

Presently there has been few of a special feed for freshwater fryr. Feed manufacture are generally reluctant to produce special feed for fry because the volume a bit so as to provide a significant advantage for this Manufacture. Generally many farmers provide grower feed  pulverized to fry feed  , The difference between the feed requirement specification for grower and starter feed for fry resulted in the growth of the fry is not optimal. Seeing this condition is necessary for an investigation to get fry feed that support optimal growth so that the impact on seed production.

The Research  aim to getting feed formulation to support the growth and survival of seed Tor Sp been done in the wet lab research and development Installation Germplasm Cijeruk. maintenance container used is an aquarium with a size of 60 x 40 x 40 cm with an effective volume of 48 liters of water. Average weight used was 1.2 g / fishl with a density of 50 fish / aquarium. The treatments were attempted intended to get the right energy content on feed that impact on growth and survival. the treatment applied is 35% protein levels with energy (GE) of
A. 2,500 kcal / kg
B. 3,000 kcal / kg
C. 3,500 kcal / kg and
D. 4,000 kcal / kg
The parameters observed weight gain, survival, feed conversion and water quality as a supporter. Long maintenance 40 days. The result showed different energy content in the feed with a protein content of 35% gives a real impact on the parameters observed. The highest population gain shown in treatment D (GE 4000 kcal): 78.55 g and the lowest in treatment B (GE 3000 kcal / kg feed) 62.44 g. Lowest feed conversion treatment D: 5.86, and the highest treatment B; 6.97, the highest individual weight gain in treatment D; 1.91 g /fish and the lowest in treatment A: 1.51. g /fish
