Catfish eggs are connected by a sticky matrix that holds the eggs together in a mass. In the hatchery, this stickiness causes problems during incubation. In addition, the gelatinous matrix of catfish egg masses can be dis-solved with sodium sulfite so the eggs can be incubated in hatching jars. Induced hatchery spawning of fish requires a continuous series of decisions, any of which if improperly made, can diminish or completely obliterate the success of the project. There are many ways to fail at each step and only a very few that are productive.
Consistent performance requires strict attention to detail.
