Roe Housing is a term used to describe the practice of providing housing for fish eggs. This type of housing is often used in aquaculture, which is the farming of aquatic organisms such as fish, mollusks, crustaceans, and plants. The term SHAD, which is an acronym for SHAD-darting, is a method of collecting fish eggs from rivers and streams for use in aquaculture. This method involves using a net to collect the eggs, which are then placed in Roe Housing for incubation and hatching.
