To investigate the relative importance of pineal and eyes in ovarian activity, catfish subjected to pinealectomy, binding, or both were exposed to continuous light (LL) or continuous darkness (DD) during the different phases of the annual reproductive cycle. Pineal or eyes have no influence on ovarian activity during the preparatory, prespawning, and spawning periods of the annual reproductive cycle under these photoregimes. However, the pineal accelerated ovarian activity under LL and DD during the postspawning period. Blinding alone has no effect on ovarian recrudescence under these regimes. However, combined surgery (blinded-pinealectomy) inhibited ovarian development under both these conditions, indicating that the pineal organ is more important than the eyes. Ovarian recrudescence occurred even in the absence of both pineal and eyes, indicating the involvement of extrapineal and extraocular photoreception in the regulation of reproductive activity in the catfish.
为了研究松果体和眼睛在鲶鱼卵巢活动中的相对重要性，在年度繁殖周期的不同阶段，对接受松果体切除、致盲或两者皆有的鲶鱼进行持续光照（LL）或持续黑暗（DD）处理。在这些光照条件下，松果体或眼睛在年度繁殖周期的准备期、产卵前期和产卵期对卵巢活动没有影响。然而，在产后阶段，松果体在LL和DD条件下加速了卵巢活动。在这些条件下，单独致盲对卵巢复旧没有影响。然而，联合手术（致盲-松果体切除）在这两种条件下均抑制了卵巢发育，表明松果体器官比眼睛更重要。即使在没有松果体和眼睛的情况下，卵巢也会复旧，这表明松果体外和眼外光感受参与了鲶鱼生殖活动的调节。
