ABSTRACT:
Described herein is a novel method for the implantation of fish eggs usually salmonidae eggs in a stream or lake bed and the accompanying apparatus. In practicing this invention the stream or lake bed substrate is subjected to high pressure hydraulic flushing to loosen the gravel and remove undesirable sediment. Once the substrate has been properly prepared fertilized eggs are injected by means of hydraulic pressure into the substrate. The egg planting device of this invention comprises a receptacle for the fertilized eggs which has a valved orifice at its base through which the eggs pass into a central chamber and which central chamber has a lateral orifice to permit the entry of water; the flow of the water being governed by a control valve and the base of the central chamber being provided with a rigid hollow tubing adapted for insertion into the substrate.
