Abstract: An ice fishing assembly of a radiant energy absorbing bubble-like cover and paraphernalia resembling commonly employed ice fishing devices. The minimum apparatus of this invention consists in an somewhat irregular dome shaped cover that is made from any material that will absorb and transmit, to the air confined under the cover, impinging solar radiant energy. In operation, the cover is placed over an ice fishing hole and its enhanced-design ability to collect radiation assures that the water surface beneath the air space confined within the cover will remain unfrozen. Conventional ice fishing apparatus such as fishing line placed on a suitable spooling device, with a tip-up flag or alarm actuating means penetrating through the cover, or in the case of solely visual means enclosed within the cover, are attachable to the cover proper or to a transitional piece that is insertable between the cover and the ice-covered water surface.
