Effects of different three live foods on growth performance and survival rates in Beluga (Huso huso) larvae
To determine the best live food and to reevaluate the optimal weaning period for beluga fish (Huso huso) larvae, seven experimental diets: Daphina (DP), Chironomids (CH), Gammarid (G), Daphina + formulated diet (DPFD), Chironomids + formulated diet (CHFD), Gammarid + formulated diet (GFD ) and formulated diet (FD ) in triplicate groups were fed to 4662 sixteen-days-old larvae which were captu...

متن کاملStudy on population growth and production of cyclopoid copepod Acanthocyclops trajani fed on different diets
In this study the effects of different algal and nonalgal diets on density and population growth rate of cyclopoid copepod Acanthocyclops trajani were studied. To this intention, the copepod were mass cultured in 120 liter tanks by feeding on different diets (5 treatments, 3 replicate in each one) including fresh composition of microalgae: Scenedesmus obliquus and Spirulina maxima (LSS), dried ...
