Title

AN INVESTIGATION ON THE EFFECT OF INITIAL FEEDING ON GROWTH RATE OF TROUT (ONCORHYNCHUS MYKISS) LARVAL STAGE

Pages

  847-854

Abstract

 In the larviculture the use of high quality dietary components is critical for rearing fish. Artemia nauplii and decapsulated cyst have very wide usage on aquaculture industry. In most of fish species, especially in fresh water fish’s larvae stage, Artemia nauplii and decapsulated cyst have very important effects on GROWTH rate and survival. In this study, effect or different initial feeding upon the second GROWTH rate of trout larvae stage was studied. To this end, the new absorbed yolk sack trout larvae were used. All larvae in five feeding treatments (artemia nauplii, decapsulated cyst, commer-cial diet mixed with decapsulated cyst, commercial diet mixed with nauplii, commercial diet) for 20 day with intensity 6 larvae per litter at tanks 35-liter were reared. Then experiment extended in these treatments with the commercial diet (only) for 20 days more. Larvae fed with the artemia nauplii in the first experiment had the highest GROWTH and the difference was significant compared with the other treatments (p<0.05). In the second experiment, after 20 day in the all treatments, the GROWTH rate, survival, SGR, FCR, condition factor, feed intake rate, Gross efficiency were measured. Results showed that in the second 20-day period, the larvae fed with commercial diet mixed with decapsulated cyst treatment in first experiment, had a significant difference with the other treatments (p<0.05).The fish that were fed with decapsulated cyst mixed with commercial diet had the highest GROWTH rate rather than the other treatments.
