FIG. 1.
Distinguishing male and female zebrafish based on large clusters of breeding tubercles (BTs). (A) Male zebrafish possess BT clusters, observed as brown lines, along the central pectoral fin rays (blue arrowheads). (B) Female pectoral fins are translucent, as they do not possess BT clusters (pink arrowhead). (C) Dorsal view of zebrafish in a standard breeding tank. Female pectoral fins (pink arrowheads) can be distinguished from male pectoral fins (blue arrowheads). (D) Under the stereomicroscope, male zebrafish possess BT clusters that appear as spike-like structures along the central fin rays. (F) These structures are absent on female pectoral fins. (E, G) Higher magnification of the central rays of male (E) and female (G) pectoral fins (red boxes in D, F) highlights the presence (blue arrowheads) and lack of BTs, respectively. All scale bars=200 μm. Photographs (A–C) were taken with an 8-megapixel camera on an iPhone 5S. Color images available online at www.liebertpub.com/zeb
