How to identify white bass

Safety

Look at this first

Diagnostic — settles it on its own

Each of these settles the identification on its own. If one is clear, you have your answer.

• Stripes faint and broken rather than clean and continuous

  Pick a single dark line on the flank and trace it. A white bass's lines are dim, interrupted, offset where they cross, and largely absent above the lateral line. A striped bass carries seven or eight sharp continuous lines that hold from behind the gill cover to the tail. The pattern is legible on a fresh fish and degrades within hours of death, so read it early.

• One tooth patch on the tongue, not two

  Put a thumb on the tongue and feel. White bass carries a single rough patch; striped bass carries two parallel ones. This is the character that separates both from the hybrid, which usually carries two patches that are joined at the rear, and it is the only reliable way any of the three are told apart when the stripes are ambiguous. It requires the fish in hand and a willingness to feel inside its mouth.

Supporting — use with other characters

Real characters that are not conclusive by themselves. Use two or three together.

• A deep body for its length, arched behind the head

  White bass is roughly a third as deep as it is long and the dorsal profile rises sharply behind the head. A striped bass of the same length is noticeably more elongate and slab-sided with a straighter back. Because it is a proportion it survives handling, and it is the character to fall back on when the stripes have faded.

• Two clearly separated dorsal fins

  The spiny first dorsal and the soft second dorsal are separate rather than joined by a membrane. This places the fish in Morone and removes the sunfishes and the drums; it does nothing to separate the three Morone a reader is actually choosing between.

• Size class as a prior

  A white bass over about two kilos is exceptional; striped bass reach many times that. So a large striped fish is unlikely to be a white bass, though a small striper is entirely likely to be mistaken for one, which is the direction the error actually runs.

What it gets confused with

• Striped bass, the main confusion, separated on stripe continuity, body depth and the tongue tooth patches.
• The white × striped hybrid, stocked into thousands of reservoirs and often the most abundant of the three; broken stripes AND two joined tongue patches point to it.
• Yellow bass, which has broken stripes as well but carries a distinctly yellow flank and whose lower stripes are offset in a characteristic step.
• White perch, a smaller Morone with no stripes at all as an adult, common in eastern waters.
