A Review on the Potential Uses of Ferns

Man has been using plants as a source of food, medicines and many other necessities of life since ancient times. Even to this day the primitive tribal societies that exist depend on the plant life in their surroundings. Though there were investigations of the edible economic values of the higher plants, especially the pteridophytes and angiosperms have been unfortunately ignored. The pteridophytes are used in Homoeopathic, Ayurvedic, Tribal and Unani medicines and provides food, insecticides and ornamentations

Application of Live Feeds in the Freshwater Ornamental Fish Larvae of Puntius Dorsalis (Jerdon)

Feeding experiment conducted under laboratory conditions, to determine the suitability of live feed for the larvae of ornamental fish Puntius dorsalis, shows the increase of specific growth rate and weight gain when they were fed with mosquito larvae( 3.284 and 8.04%/day),chironomus larvae(3.308 and 6.24%/day),chopped earthworm (2.618 and 4.39%/day). The maximum growth rate,0.614g was observed in mosquito larvae feed followed by chironomus larvae(0.522 g),chopped earthworm(0.411g) and plankton(0.405g). The present study indicates that mosquito larvae could be used as a suitable live feed for feeding Puntius dorsalis larval fishes
