This particular approach is one that groups might utilize to enhance salmon populations in small streams where the sponsoring group does not have a hatchery infrastructure in place and the site is logistically challenging, ie: no road access and difficult terrain for equipment etc. All that's required is a stream with good water quality parameters, good substrate (spawning gravels) and access to eyed eggs.
The base of a large plastic recycled drum was cut and used as a cylinder form to pile gravel and coho eggs. Layer by layer the eggs and rocks were stacked until volunteers were ready to remove the form. This artificial redd is now left alone for the remainder of the egg incubation period.
