Growth performance of ornamental fish species Poecilia reticulate W. Peters and Pethia conchonius F. Hamilton subjected to various treatments

The present investigation suggested that the growth performance of Guppies (Poecilia reticulata) and Rosy barbs (Pethia conchonius) was assessed and prepared six different types of formulated novel diets comprised of some nutritional natural ingradients of probiotics (T1), Spirulina (T2), synthesized zinc oxide nanoparticles from Spirulina (T3), Cynodon dactylon (T4), synthesized zinc oxide nanoparticles from C. dactylon (T5) and combination of all five (T6) and the results was compared with the supplied commercial diet as a control. The growth trend of guppies and rosy barbs from all the supplied formulated novel diet of T6 resulted better rather than the imported commercial diets respectively. The natural biologically new novel diet for ornamental commercial fed might be replaced by experimental diet for the better growth production of guppies and rosy barb of ornamental fish.
