Como identificar Pescada

Para identificar Pescada (Cynoscion spp.), observe estas características principais.

Características físicas

Formato do corpo

elongated

Coloração

Generally silvery, often with iridescent reflections (e.g., pink, blue, green, gold) on the dorsal surface, fading to white or silver on the belly. Some species may have spots or faint bars.

Tipo de escama

ctenoid

Posição da boca

superior

Características distintivas

Two dorsal fins, the first spiny and the second soft-rayed., A prominent, often large, canine-like tooth or pair of teeth in the upper jaw, particularly noticeable in species like Cynoscion regalis (Weakfish)., Lateral line typically runs straight or slightly arched., Large mouth extending to or beyond the posterior margin of the eye.

Nadadeira dorsal

Two dorsal fins; the first is spiny with 8-11 spines, and the second is long and soft-rayed with 1 spine and 20-30 soft rays. The two fins are typically separated or barely connected.

Nadadeira caudal

Caudal fin typically truncate to slightly emarginate, sometimes pointed in juveniles.

Nadadeira peitoral

Pectoral fins are moderately long, typically reaching to or beyond the origin of the pelvic fins.

Nadadeiras características

Pelvic fins thoracic, located below or slightly anterior to the pectoral fins.

Dicas de identificação

1. 1

   Upper Jaw Teeth

   Look for one or two prominent, canine-like teeth at the front of the upper jaw. This is a key distinguishing feature for the genus Cynoscion.

2. 2

   Lateral Line

   Observe the lateral line; it is typically straight or only slightly arched, unlike some other sciaenids.

3. 3

   Dorsal Fins

   Note the two distinct dorsal fins, with the first being spiny and the second soft-rayed. The separation between them can vary slightly by species.

4. 4

   Body Coloration

   While generally silvery, specific species may have distinct patterns, such as spots (e.g., Cynoscion nebulosus - Spotted Seatrout) or iridescent hues.

5. 5

   Fin Ray Counts

   For precise species identification, fin ray counts (especially in the second dorsal and anal fins) and vertebral counts are often necessary and require expert examination.
