<jats:title>Abstract</jats:title><jats:p>The leuteinizing hormone‐releasing hormone (LH‐RH) analog, DAla<jats:sup>6</jats:sup>DesGly<jats:sup>10</jats:sup> LH‐RH‐ethyl amide, delivered by intraperitoneal or intracranial injection was an effective agent for the induced spawning of channel catfish (<jats:italic>Icrulurus punctatus</jats:italic>) held in aquaria. A daily dose of 100 μg LH‐RH analog (LH‐RHa) per kg fish body weight was recommended as the dosage schedule of choice, but daily doses as low as 1 cg LH‐RHa per kg fish body weight induced spawning of channel catfish. LH‐RHa was as good or better than human chorionic gonadotropin or carp pituitary to induce spawning of channel catfish in aquaria. Sham‐injected (control) channel caffish spawned in this study contradicting observations in earlier studies.</jats:p>
