However, in several cases, the spawning jar method has some advantages. If spawning other species such as Chinese carps, striped bass or hybrid striped bass, no new equipment is needed to include catfish. Less space is needed for hatching jars as opposed to hatching troughs. Less expensive to use this method in some cases. Three liter soft drink bottles can be used very satisfactory in the place of expensive spawning troughs or McDonald hatching jars.
Less electricity is needed since no motor driven paddles are needed for agitation.
There is less chance for disease infection on the eggs since the matrix tissue is removed. The spawning jar method offers some advantages over traditional means of hatching catfish. This method can allow existing hatcheries to include catfish in their production without the addition of expensive equipment.
